Variations on the Author
“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Ring conformations and intermolecular interactions in two fused dibenzoazocines
5-Acetyl-2-chloro-8,11-dimethyl-5,6,11,12-tetrahydrodibenzo[b,f]azocine, C(19)H(20)ClNO, (I), crystallizes as a single fully ordered isomer, but 14-acetyl-8,11-dimethyl-7,8,13,14-tetrahydrobenzo[f]naphtho[1,2-b]azocine-14-acetyl-8,9-dimethyl-7,8,13,14-tetrahydrobenzo[f]naphtho[1,2-b]azocine (74/26), C(23)H(23)NO, (II), exhibits threefold whole-molecule disorder involving both configurational and structural isomers. In (I) and in the predominant form of (II), the azocine rings adopt very similar conformations, forming boat-shaped rings having approximate twofold rotational symmetry. There are no direction-specific intermolecular interactions in the crystal structure of (I), but the molecules of (II) are weakly linked into chains by an aromatic pi-pi stacking interaction. The compounds were made under green conditions using an acid-catalysed cyclization process having very high atom utilizatio
Helluoherpia vieiralaneroi Cobo & Kocot 2021, sp. n.
Helluoherpia vieiralaneroi sp. n. (Figure 6, Table 2) Type material. Holotype: ZSM Mol 20171268. (Zoologische Staatssammlung München). Serial sections (seven slides) and sclerites (one SEM stub, five slides). Brazil Basin, DIVA 3 Me 79/1 area 2, station 561 (26º 34.78’S, 035º 13.90’W), 4484.7 to 4503 m depth. Derivatio nominis. Male genitive in honor of Dr. Vieira Lanero (University of Santiago de Compostela). Diagnosis. Small animal (<2 mm) with elongate body. Appearance slightly scaly. With a depression around the atrio-buccal cavity. With lanceolate, leaf-shaped scales as the main type of sclerites, pedunculate, lanceolate scales, and solid, curved acicular sclerites. With a single pedal fold. Common atrio-buccal cavity is very small and without papillae. Helluoherpia - type ventrolateral foregut glands. Radula with three denticles. Mantle cavity very small. With seminal vesicles. Description. Habitus: Small animal (1.35 mm long, 0.2 mm wide in the middle) with the anterior end rounded and somewhat wider than the rest of the body (0.3 mm). With a small ventral depression where the atrio-buccal opening is located (Figure 6 A). The posterior end was externally damaged, but good histological preparations were still obtained. The pedal groove is evident externally. Yellowish-white in 96 % ethanol. The imbricate arrangement of the sclerites is easily observed, although it does not have a very scaly appearance. Mantle: Thin epidermis (1.5 to 2.5 μm thick) without epidermal papillae. Thin cuticle (5 to 7.5 μm) with three types of sclerites arranged in a single layer: 1) Regular lanceolate, leaf-shaped scales (Figure 6 B, C) that cover the entire body (60 to 80.5 μm long, 20 to 12.5 μm wide). The other sclerites appear intermittently between them. 2) Irregular, pedunculate, lanceolate leaf-shaped scales (Figure 6 D) are the second most common type of sclerites (34 to 36 μm long, 10 to 12 μm wide). 3) Solid, acicular, sclerites (Figure 6 E, D) are present, concentrated mainly in the dorsal region. These are curved sclerites with a narrow proximal region and are somewhat flat (but rounded in cross-section) in the middle region, with a pointed end (60 to 65 μm long, 0.8 to 1.5 μm wide). These acicular sclerites are concentrated mainly in the dorsal region. They are the least abundant type. No sclerites specific to the pedal groove were found. Pedal groove and mantle cavity: The pedal pit is very glandular (Figure 6 F-2). It appears just posterior to the atrium and continues internally (25 μm long with an opening that is 10 μm in diameter, 10 to 32 μm wide, 5 to 10.5 μm high). The anterior pedal glands connect with the dorsal wall of the pedal pit. They are very voluminous ven-trally and reach the mantle cavity. The pit originates as a single, triangular pedal fold in the anterior region (7.5 μm wide 8 μm high), which flattens in the medial and posterior body regions (10.5 to 17.5 μm wide, 7.5 μm high). The mantle cavity opening is ventro-posterior and very narrow (5 to 6 μm; Figure 6 G-5). In the sections it looks like a folded duct as it is small (20 μm long, 27.5 to 30 μm wide, 32.5 μm high) and is virtually confined to the opening of the spawning duct (Figure 6 G-5). Digestive system: The mouth, which is located at the posterior end of the atrium, continues as a foregut that is narrow and circular in cross-section (32.5 μm long, 5 to 15 μm in diameter; Figure 6 F-2) and surrounded by a thin layer of longitudinal musculature (<2.5 μm). It also has a small dorsal pouch (12.5 μm long, 15 μm wide, 10 to 15 μm high). Radula with three straight, identical narrow denticles per tooth (<1 to1.2 μm wide, fragments of 10 μm long) (Figure 6 H-H´). Fragments of a straight radular base were also observed (2 to 8 μm anterior to posterior and 2 μm high) (Figure 6 H-H´´). The fragmented tooth was observed in the radular sac. In this area, the ventrolateral foregut glands (type A) open ventrally in the foregut as a single duct (45 μm long). The ducts of the ventrolateral foregut glands are long and surrounded by a strong layer of longitudinal and circular musculature (approximately 5 μm thick). Most of the glandular cells discharge into the middle of the ducts, with the posterior region of the ducts free of glandular cells. The ventrolateral foregut glands are characteristic and were described for the first time for the type species of the genus Helluoherpia (H. aegiri) (Handl & Büchinger 1996) so they can be referred to as Helluoherpia - type. The midgut has a short dorsal caecum (10 μm long, 20 μm wide), just below where the esophagus ends. This caecum is circular in cross-section and similar in diameter to the foregut. The rectum emerges dorsally in the mantle cavity (5 to 5.5 μm in diameter) and its wall is made up of sparsely ciliated. Nervous system and sense organs: The cerebral ganglion (32.7 μm long, 62.5 to 82.5 μm wide, 32.5 to 70 μm high; Figure 6 F-2) and most of the ganglia were easily observed. The pedal ganglia (5 μm long, 5 μm in diameter) are located on both sides of the pedal pit and are joined by a small (<2 μm wide) commissure. The supra-rectal com-missure is short and narrow (7.5 μm long, 5 to 6 μm thick). The atrium is very small (15 μm aperture and full length, 25 μm wide and 10 to 15 μm high) with no atrial papillae, but with a glandular wall (Figure 6 F-1). Gonopericardial system: Well-formed gonads with the reproductive cells (lateral oocytes and spermatozoa in the central area) concentrated in their anterior region. The pericardium is long and narrow (217 μm long, 22.5 μm wide, 7 to 30 μm high; Figure 6 G-3), with a short heart attached to its dorsal wall. The pericardioducts arise in the mid-posterior region of the pericardium; they form a large seminal vesicle (50 μm long, 25 to 30 μm wide and 30 to 55 μm high; Figure 6 G-4) that is directed toward the posterior end, and although it has an unpaired origin, the posterior region is bi-lobed. The pericardioducts run parallel to the pericardium and the midgut, on both sides of the spawning duct as a pair of circular tubes (120 μm long and 7.5 to 12.5 μm in diameter; Figure 6 G-3). The spawning duct is unpaired (175 μm long) in all its extension. The pericardioducts are centrally connected to its anterior region (52.5 μm wide, 30 to 45 μm high: Figure 6 G), which is narrower than the middle region (70 to 75 μm in diameter). The spawning duct narrows again in its posterior region (30 to 40 μm in diameter) and opens into the mantle cavity as a wide ciliated duct (opening 25 to 30 μm wide and high), which loses the surrounding musculature layer (2.5 to 4 μm). Without copulatory stylets. Remarks. The classification of Helluoherpia vieiralaneroi sp. n. within Dondersiidae is determined by the type of mantle sclerites, the ventrolateral foregut glands (type A), the radula, and the absence of respiratory folds. The description of the radula of H. vieiralaneroi sp. n. is based on fragments found in the radular sac and it is possible to affirm the presence of three denticles, which have an arrangement on the radula consistent with the genus Helluoherpia (Handl & Büchinger 1996). The inclusion of the new species in this genus is due to: 1) the sclerites (leaf-shaped scales and solid needles); 2) the radula; 3) the lack of a dorsoterminal sensory organ, copulatory stylets and respiratory folds; 4) the presence of a seminal vesicle, and 5) the peculiarities of the ventrolateral foregut glands (type A; Helluoherpia - type). Helluoherpia vieiralaneroi sp. n. is considered a new species based on its geographical distribution and a combination of anatomical characters that set it apart from the only other known species of the genus, Helluoherpia aegiri. Externally it resembles H. aegiri although the specimen studied here is much smaller (1.3 mm) than the holotype of H. aegiri (6 mm; Handl & Büchinger 1996). The main type of leaf-shaped scales of the two species are similar in shape and size, but in the new species the solid acicular sclerites are curved and somehow flattened, while those of H. aegiri are straight (Handl & Büchinger 1996), and it also has fewer pedunculated leaf-shaped scales. The basic internal anatomical characteristics of H. vieiralaneroi sp. n. and H. aegiri are similar but there are some important differences: a) H. vieiralaneroi sp. n. has a very small atrium, with no atrial papillae, whereas in the atrium of H. aegiri, there are large globular papillae (Handl & Büchinger 1996); b) In H. vieiralaneroi sp. n. the ducts of the ventrolateral foregut glands are shorter, and they run parallel to the foregut and then to the ventral region, and not to the dorsal region as in H. aegiri (Handl & Büchinger 1996); c) H. vieiralaneroi sp. n. has a small midgut caecum that is absent in H. aegiri; d) In H. vieiralaneroi sp. n. the seminal vesicles are exceptionally bulky and extended toward the posterior end, whereas in H. aegiri, they are smaller and extend toward the anterior region; e) The spawning duct in H. vieiralaneroi sp. n. is much longer and bulkier than in H. aegiri (Handl & Büchinger 1996); f) The pericardium is markedly larger in H. vieiralaneroi sp. n. than in H. aegiri, which has a very short pericardium (Handl & Büchinger 1996) and it also extends far posteriorly from where the pericardioducts fuse with it.Published as part of Cobo, M.

Inopinatamenia calamitosa Cobo & Kocot 2021, sp. n.
Inopinatamenia calamitosa sp. n. (Figure 7, Table 2, 3) Type material. Holotype: ZSM Mol 20171269 (Zoologische Staatssammlung München). Serial sections (eight slides) and sclerites (one SEM stub, four slides). Brazil Basin, DIVA 3 Me 79/1 area 2, station 561 (26º 34.78’S, 035º 13.90’W), 4484.7 to 4503 m depth. Derivatio nominis. From Latin calamitosus-a-um: calamitous. Due to the overcoming of difficulties during the first author’s PhD studies. Diagnosis. Elongate and narrow body with sharp ends. Sclerites as lanceolate, leaf-shaped scales. Atrium with simple, pedunculate papillae. Flat pedal fold. Monoserial radula with six denticles per tooth: each tooth consists of a dumbbell-shaped base with three denticles on each side. Ventrolateral foregut glands of type A, with very short, wide and muscular simple ducts with inner musculature and extraepithelial gland cells. Midgut without lateral constrictions. With respiratory folds. Description. Habitus: Elongate animal (2.18 mm long, 0.2, 0.15, 0.10 mm wide in the anterior, middle and posterior part respectively), with pointed anterior and posterior ends (Figure 7 A). White in 96 % ethanol but with a translucent cuticle, especially, in the posterior region where the imbricated arrangement of the scales and the absence of intestinal constrictions can clearly be seen. Pedal groove not externally evident. Mantle: The cuticle and epidermis are displaced and quite deteriorated in most of the sections obtained, so the measurements (7.5 to 8 μm cuticle, 1.5 to 4 μm epidermis) are not very precise. Epidermal papillae are absent and the sclerites are embedded in a single layer. Sclerites as lanceolate, leaf-shaped scales (Figure 7 B, C) that are 94 to 100 μm long and 20 to 25 μm wide with a narrowing in the proximal end. Pedal groove and mantle cavity: The pedal pit is a short slit (17.5 μm long, 15 μm wide, 7.5 to 10 μm high; Figure 7 D-3), with almost no cuticular division between it and the opening of the common atrio-buccal cavity. The pedal fold is flat and does not change in shape or size (6.25 to 7.5 μm long, 2.5 μm high) along the length of the body until the mantle cavity. Whether or not it enters the cavity is unclear because of the quality of the histological sections. The anterior follicular pedal glands are bulky and extend towards the dorsal region of the body. The opening of the mantle cavity (35 to 37 μm wide, 20 to 40 μm high) is almost terminal (Figure 7 E). The epithelium of the mantle cavity is folded. The folds are interpreted as respiratory folds because of their position, shape, and the presence of ciliated cells. There are six or eight folds. The rectum (dorsal) and the spawning duct (ventral) open centrally into the mantle cavity. Remains of a posterior mass of glandular cells were found but their function could not be determined. Digestive system: The mouth (located within the atrium) gives way to an initially narrow foregut (15 μm long, 22.5 μm wide, 5 to 15 μm high), which becomes slightly wider (25 to 30 μm long, 20 to 25 μm in diameter). In this pre-radular region, the foregut runs almost parallel to the pedal groove. The foregut has a very glandular epithelium, and it is surrounded by longitudinal musculature (5 to 7.5 μm). In the radular region, the longitudinal musculature layer surrounding the foregut is reinforced with a layer of circular musculature (Figure 7 D-4). The ventrolateral foregut glands consist of a pair of short and wide, simple ducts (15 μm long, 12.5 to 20 μm in diameter) with inner musculature walls (Figure 7 D-4, 4’) and extraepithelial gland cells (type A). The gland cells are of two types (according to the shape and the staining). Most of the gland cells, which stained deep red, discharge into the ducts along their entire length, although with a greater concentration in their anterior region. In this area and dorsally, a cluster of a second type of gland cells, which are more rounded and stained intensely orange, also discharge into the ducts. The radular sac is short (15 μm long, 5 μm in diameter) and runs very close to the foregut, flanked by the ven-trolateral foregut glands (Figure 7 D-4, 4’). The monoserial radula consists of teeth having a plate with a dumbbellshaped outline (18.9to 19.2 μm long, 4.74 μm wide at the ends and 3.22 μm wide in the center; Figure 7 D-4’, F) with three denticles on each side. The outer-most denticles are the largest (8.8 to 9 μm long and 1.63 to 1.7 μm wide) and the innermost denticles are the smallest (6.41 to 6.8 μm long, 1.45 to 1.53 μm wide). The denticles are narrow and equidistant from each other. The inner denticles are slightly curved while the outer ones are straight. The esophagus is narrower than the foregut (22.5 to 25 μm wide, 5 to 12 μm high) and very glandular. The longitudinal musculature surrounding the foregut disappears in the esophageal region. The esophagus terminates centrally into the midgut without forming a sphincter. The midgut has tenuous lateral constrictions in its anterior region. The ciliated rectum emerges centrally in the mantle cavity. Nervous system and sense organs: The cerebral ganglion (32.5 μm long, 25 to 37.5 μm in diameter) is nearly circular in cross-section and is located dorsal to the middle region of the foregut (Figure 7 D-3). The buccal ganglia (10 μm in length, 5 to 7.5 μm in diameter) surround the anterior half of the ventrolateral foregut glands. The pedal ganglia (20 μm in length 7.5 to 10 μm in diameter) are located beyond the posterior end of the pedal pit (after about 25 μm). The opening of the atrium is wide (20.5 μm; Figure 7 D-1,2) and located far to the anterior of the body. It gives way to a large horseshoe-shaped cavity (52.5 μm in length, 45 μm in width, up to 50 μm in height) that is surrounded by a compact glandular tissue layer. There are numerous long, pedunculated papillae (12.5 μm long, papilla head 2.5 to 3 μm wide, <2.5 μm peduncle; Figure 7 D-2), which take up almost all the space of the cavity (Figure 7 D-2). The anterior-most region of the atrium (Figure 7 D-1) is occupied by a characteristic compact cellular accumulation that represents a central fold Gonopericardial system: Oocytes were observed in the gonads. The pericardium is wider in the middle region (12.5 to 15 μm in diameter) before re-narrowing (5 μm in diameter) where the pericardioducts arise (Figure 7 E). A complete heart was not observed, although some blood cells were observed in the lumen of the pericardium. The pericardioducts are narrow (55 μm long, 5 to 7.5 μm in diameter) and join to the dorsal surface of the spawning duct in its middle region. The spawning ducts are completely fused into a single tube. In its anterior region, the lumen of the fused spawning duct is wide (12.5 to 22.5 μm in diameter) and surrounded by a thick glandular layer (20 μm). As the spawning duct narrows, the glandular layer becomes thinner, as does the outer layer of longitudinal musculature (2.5 to 3.25 μm), before discharging centrally into the mantle cavity. No copulatory stylets or other accessory reproductive structures were observed. Remarks. The description of Inopinatamenia gen. n. is based on the combination following characters: 1) Monoserial radula with six denticles per tooth. 2) Presence of a single type of scales. 3) Ventrolateral foregut glands (type A) with two different gland cells opening into the ducts. 4) No copulatory stylets or accessory abdominal spicules. 5) No seminal vesicles or receptacles. 6) With six or eight respiratory folds. 7) With a posterior gland, of unknown function, that connects with the mantle cavity. The new genus Inopinatamenia is mainly based on the unique type of radula. The number of denticles of the radula teeth is fundamental to differentiation of the genera of Dondersiidae (according to the current taxonomy, at least) and was one of the main characters in the diagnoses of the genera Helluoherpia and Squamatoherpia (Handl & Büchinger 1996; Büchinger & Handl 1996). Inopinatamenia calamitosa sp. n. is unique among Dondersiidae in that it has a monoserial radula with six denticles per tooth, where each tooth consists of a dumbbell-shaped base with three denticles on each side. The family Dondersiidae was originally defined by the presence of at least two types of sclerites. However, the dondersiid Squamatoherpia Büchinger & Handl, 1996 only has one type, which justifies the inclusion of Inopinatamenia gen. n. also has only one type of sclerites, in this family. The scales (lanceolate leaf-shaped) resemble those of Micromenia amphiatlantica but they are smaller, M. amphiatlantica also has acicular sclerites and the internal characters of the two species are very different (Cobo & Kocot, 2020). The ventrolateral foregut glands in Dondersiidae are of type A. In Inopinatamenia calamitosa n. sp. they are very short, wide and muscular, with two different cell types opening into the ducts. One type opens along the entire extension of the ducts while the other exoepithelial glandular cells connect with the ducts just in their anterior region. Neither of the glandular cell types have posteriorly bent necks, so, according Handl and Todt (2005) they could be classified as Pararrhopalia - type.Published as part of Cobo, M.
