The David W. Fentress Family Letters, 1856-1969
No full textTranscript of a letter by an unidentified author to David Fentress regarding sharing federal newspapers and the banning of federal newspapers in some areas. The author passes on the news of the war including the destruction of the Federal merchantmen by the Confederate fleet. He passes along world news: Russia preparing to go to War with Europe and how that could negatively affect the Confederacy. There is also speculation on the future of the war

Massisteria marina Larsen and Patterson 1990
No full textMassisteria marina Larsen and Patterson, 1990 (fi gures 21q, 22f) Description. Cells measuring 3-6.5 Mm, dorso-ventrally fl attened irregular body. Cells produce delicate pseudopodia with extrusomes, which extend radially from the cell and normally adhere to the substratum. Two short curved fl agella arise from the dorsal side of the cell and are relatively inactive. Rarely observed. Remarks. Generally, our observations are in good agreement with those of Larsen and Patterson (1990). Previously reported size ranges are 2.5-5 Mm (Patterson and Fenchel, 1990), 3-9 Mm (Larsen and Patterson, 1990; Vørs, 1992a, 1992b), 4.2-7 Mm (Ekebom et al., 1996), 2.5-4 Mm (Tong, 1997a) and 2-9.5 Mm (Tong et al., 1998). This species was found in marine sites in subtropica l and tropical Australia, Brazil, Denmark, Gulf of Finland, equatorial Paci fi c and Panama (Larsen and Patterson, 1990; Vørs, 1992a, 1992b; Vørs et al., 1995; Ekebom et al., 1996; Tong, 1997a; Tong et al., 1998).Published as part of Lee, Won Je & Patterson, David J., 2000, Heterotrophic flagellates (Protista) from marine sediments of Botany Bay, Australia, pp. 483-562 in Journal of Natural History 34 on page 54
Cafeteria roenbergensis Fenchel and Patterson 1988
No full textCafeteria roenbergensis Fenchel and Patterson, 1988 (fi gures 20g, 21d, e) Description. Cells are D-shaped, 3.5-5 Mm long, and laterally compressed. There is a shallow groove on the left side of the cell. Two fl agella of similar length emerge subapically and are slightly longer than the cell. The anterior fl agellum is directed perpendicular to the ventral face of the cell of attached cells. The posterior fl agellum is reflexed, passing over one face of the cell and then attaching to the substratum by the tip. In swimming cells, the anterior fl agellum is directed forwards and beats with a sine-wave, and the posterior fl agellum is directed backwards and trails. Usually moves fast following a spiral path, but sometimes moves slowly. Food particles (bacteria) may be ingested near the posterior part of the ventral groove. Not common. Remarks. Generally, our observations are consistent with descriptions of Fenchel and Patterson (1988) and Larsen and Patterson (1990). Previous studies reported the size range to be 1.5-10 Mm (Fenchel and Patterson, 1988; Larsen and Patterson, 1990; Vørs, 1992a, 1992b, 1993a, 1993b; Patterson et al., 1993; Vørs et al., 1995; Ekebom et al., 1996; Patterson and Simpson, 1996; Tong, 1997 a, 1997b; Tong et al., 1997, 1998; Bernard et al., 1999). This species has been widely found from marine sites in Antarctica, subtropical and tropical Australia, North Atlantic, Baltic, Denmark, England, Gulf of Finland, Greenland and equatorial Paci fi c. This species resembles Cafeteria minuta (Ruinen, 1938) Larsen and Patterson, 1990 in general appearance, but is distinguished because C. minuta has a longer anterior fl agellum. Cafeteria roenbergensis resembles C. marsupialis Larsen and Patterson, 1990 in general appearance and in having a short anterior fl agellum, but C. marsupialis is larger and has a ventral groove with a posterior channel leading into the cell. It may not be clearly distinguished from Acronema sippewissettensis (Teal et al., 1998), the fl agella of which are said to be acronematic. Cafeteria roenbergensis may occasionally occupy about 6-20% of the heterotrophic fl agellate population (Fenchel, 1982; Tong, 1997b) and is cosmopolitan.Published as part of Lee, Won Je & Patterson, David J., 2000, Heterotrophic flagellates (Protista) from marine sediments of Botany Bay, Australia, pp. 483-562 in Journal of Natural History 34 on page 53
Protaspis obliqua Larsen and Patterson 1990
No full textProtaspis obliqua Larsen and Patterson, 1990 (fi gures 22j, 23i, j) Description. Cell slightly oval or roundish, 12-32 Mm long, 10-27 Mm wide, dorsoventrally fl attened, with thickened cortex. With a ventral median groove; cell indented anteriorly and posteriorly where groove meets margin. Subapically, the right margin of the groove forms a protrusion. With two fl agella inserting under the protrusion; the anterior fl agellum is about 0.5 times the length of the cell and the posterior fl agellum is about 0.5 -1.5 times the length of the cell. The nucleus is without nuclear caps, is located subapically in a median position, is rounded and is 5-13 Mm in diameter. Contained many food particles up to 5 Mm long. Commonly observed. Descriptions based on observations of 16 cells. Remarks. This species was described from marine sites in tropical Australia, Fiji and England by Larsen and Patterson (1990) and Tong (1997b). Cell length was reported to be 8.5-20 Mm by previous authors. Generally, our observations are in accordance with those of Larsen and Patterson (1990) although our length range extends the previous range. Although the identities of most species within the genus are di ffi cult to establish, the protrusion near the fl agellar insertions makes this species easy to identify.Published as part of Lee, Won Je & Patterson, David J., 2000, Heterotrophic flagellates (Protista) from marine sediments of Botany Bay, Australia, pp. 483-562 in Journal of Natural History 34 on page 54
