DISTRIBUTION: C Peru (Junfn), south through W Bolivia, to C Chile and WC Argentina. SYNONYMS: abrocodon, arenarius, boedeckeri, campestris, capito, chilensis, dichrous, fulvescens, glirinus, griseoflavus (of Philippi, 1900), illapelinus, lanatus, limatus, megalotis, melanotis, melanotus, mollis, platytarsus, posticalis, ricarulus, rupestris, segethi. COMMENTS: See accounts of P. bonaeriensis, P. caprinus, P. definitus, P. magister, P. osgoodi, P. wolffsohni, and P. xanthopygus, previously arrayed as subspecies of P. darwini by Pearson (1958) and /or Hershkovitz (1962), for references addressing their specific status. The complexity of populations comprising this species urges still further revisionary attention.Published as part of Guy G. Musser & Michael D.

Geospiza darwini Rothschild and Hartert
No full textGeospiza darwini Rothschild and Hartert Geospiza darwini Rothschild and Hartert, 1899: 158 (Culpepper Island, Galapagos). Now Geospiza conirostris darwini Rothschild and Hartert, 1999. See Hellmayr, 1938: 130, Paynter, 1970b: 164, and Dickinson, 2003: 796. HOLOTYPE: AMNH 516980, adult male, collected on Darwin (5 Culpepper) Island, 01.39S, 92.00W (Paynter, 1993), Galapagos Islands, Ecuador, on 27 July 1897, by Rollo Beck on the Webster-Harris Expedition (no. 157). From the Rothschild Collection. COMMENTS: No type was designated in the text of the original description, where measurements were given for four males and one female, but Beck’s specimen no. 157 is designated as the type of Geospiza darwini in the same publication on pl. VI, fig. 21, a drawing of the beak of the holotype. Reference to this plate is also written on the reverse of the Rothschild type label of AMNH 516980. Paratypes in AMNH, all collected on Darwin Island on the Webster-Harris Expedition in 1897, are: AMNH 516977, adult male, 26 July, by Harris; AMNH 516978, adult male, 26 July, by Hull; AMNH 516979, immature male, 27 July, by Drowne; AMNH 516785, adult male, 27 July, by Beck, the last three now identified as magnirostris. I think that Rothschild and Hartert considered the immature bird to be a female. The right wing of that specimen is missing feathers, but the measurement of the left wing is 84 mm, the measurement given for the female.Published as part of LeCroy, Mary, 2012, Type Specimens Of Birds In The American Museum Of Natural History Part 10.

Generating synthetic social graphs with Darwini
No full textSynthetic graph generators facilitate research in graph algorithms and graph processing systems by providing access to graphs that resemble real social networks while addressing privacy and security concerns. Nevertheless, their practical value lies in their ability to capture important metrics of real graphs, such as degree distribution and clustering properties. Graph generators must also be able to produce such graphs at the scale of real-world industry graphs, that is, hundreds of billions or trillions of edges.In this paper, we propose Darwini, a graph generator that captures a number of core characteristics of real graphs. Importantly, given a source graph, it can reproduce the degree distribution and, unlike existing approaches, the local clustering coefficient distribution. Furthermore, Darwini maintains a number of metrics, such as graph assortativity, eigenvalues, and others. Comparing Darwini with state-of-the-art generative models, we show that it can reproduce these characteristics more accurately. Finally, we provide an open source implementation of Darwini on the vertex-centric Apache Giraph<sup>TM</sup>&nbsp;model that can generate synthetic graphs with up to 3 trillion edges.</jats:p
Camponotus darwini subsp. themistocles For.
No full textCamponotus Darwini For. st. Themistocles For. Cette forme ne constitue qu'une race du Darwini tres voisine de robustior For. La [[worker]] maxima atteint 11 mill. La tete est plus large que le pronotum. L'epistome n'est plus carene chez le [[worker]] au-dessus de 10 mill. de long, comme du reste chez robustior For., mais en differe, comme l'indique M. Forel, par le pronotum plus anguleux, la face basale de l'epinotum plus longue et plus convexe. La pilosite beaucoup plus espacee (ne formant pas pelisse); par contre, il y a quelques poils fins dresses sous le bord inferieur des cuisses, et surtout par la ponctuation plus regu- liere, tandis qu'elle est presque reticulaire et transversale chez robustior.
