broad band of the same bordered with yellow, crosses the closed femora ^ 

 tibiae and tarsi. A similar one crosses the fore-arm. Upper lip varied with 

 yellow ; a band of the same, extending from the angle of the mouth to the 

 shoulder. Under surface of the belly and extremities, saffron yellow, with 

 some irregular medial spots of an orange bay color. 



Length from muzzle to end of coccyx' 1 inch, 2\ lines. Femur from coccyx 

 6 lines, tibia nearly 7 lines. 



Habitat. Ceylon. Mus. Acad. Nat. Sciences. From Mr. H. Cuming, in ex. 



Phyllobates truncatus Cope. 



Skin above and below smooth, except some faint granulations upon the 

 posterior part of the abdomen. Tongue small, linear, entire. Thumb nearly 

 as long as the middle digit. Front and canthus rostralis convex. Muzzle con- 

 cave truncate, elevated ; nostrils lateral. Tympanum very near the eye, less 

 than half its size. 



Coloration. Upper and lower surfaces of head, body and extremities a dark 

 ferruginous maroon. A pale, curved line upon each side; beneath this another 

 one, which unites with its fellow upon the anterior part of the abdomen. From 

 this point of junction a medial band takes its rise, and bifurcates posteriorly. 

 A pair of parallel lines upon the throat, which unite anteriorly, following the 

 curve of the mandible. Extremities sparsely and irregularly spotted with the 

 same faint shade. 



Habitat. ? New Grenada. Mus. Academy. From the Philadelphia Museum, 

 in exchange. 



The species of this genus hitherto described, are P. bicolor Bibron, from 

 Cuba, P. melanorrhinus Berthold, from New Granada, and P. auratus 

 Girard, from Chili.

"Salamandra togata Valencienes, Mas. Paris." Dumeril. 



Specimens of this fine Salamander are now in possession of the Academy and 

 of the Smithsonian Institute, which were brought from Jalapa, Mexico, by the 

 well known collector, Sr. De Oca. Though it is a species apparently well 

 knojvn in European collections, considerable confusion exists with regard to 

 the synonymy. This it is the object of the present article to set right as far as 

 the means at the author's dispo.-al may enable him to accomplish it. 



The first published notice of this species is probably that of Professor S. F. 

 Baird, in his valuable " Revision of the North American Tailed Batrachia," as 

 above cited. He supposed it to be the Oedipus platydactylus of Tschudi, 

 as it appears to me incorrectly, though the meagre diagnosis of that author 

 renders any identification sufficiently hazardous. The name at the head of this 

 article is that of Dr. J. E. Gray, whose description in the " Catalogue of Ba- 

 trachia Gradientia in the British Museum," no doubt, applies to this species. 

 It is the first name published with an appropriate specific diagnosis, and there- 

 fore is adopted here. Dr. Gray was, however, not aware that to the present 

 species belongs the synonymy and notice of the structure of the toes, quoted 

 from Baird, under the genus Oedipus of the " Catalogue." That this is the 

 case, I have upon the excellent authority of Prof. Baird himself, who states 

 that the appearance of " sucker-like discs upon the extremities of the toes, 

 similar to those of Hyla," resulted from the contraction of the integuments 

 about the proximal phalanges, in an old specimen, thus giving prominence to 

 the small tubercle upon the inferior surface of the extremity of each toe. The 

 Oedipus of Gray appetrsto be the Oedipus of Tschudi, but I have seen neither 

 specimens nor descriptions which correspond with that of his 0. variegatus.
