Amphibians and Reptiles of Santa Marta 49 



List of Species 

 Caudata 

 Oedipus adspersus (Peters). — San Lorenzo, 4,500 to 7,000 feet; Rio 

 Frio, 1,000 m. (U. S. National Museum) ; heights east of San Miguel, 

 6,000 to 7,000 feet (M. A. Carriker). Found principally in bromelias in 

 the trees and on the ground ; occasionally found in decaying logs and stumps 

 or under decaying leaves. 



This is a viviparous species, and both young and adults were taken in 

 the bromelias. 



Sauentia 



Phyllobates subpiinctatus (Cope). — San Lorenzo, 2,200 to 7,000 feet; 

 heights west of San Miguel, 7,000 feet, and Don Diegoi (M. A. Carriker). 

 A ground form generally found near water, and usually occurring in num- 

 bers where there are small clearings grown up to grass and herbaceous 

 plants. 



.'Vlthough common, this species is a difficult one to collect and study 

 in the Santa Marta Mountains. The breeding habits and tadpole have been 

 described (Ruthven and Gaige, Occ. Papers, Museum of Zoology, Univ. 

 of Michigan, No. 10). The eggs have not been found, but they are evi- 

 dently laid on the land. Adult males carrying tadpoles have been found 

 from June 4 to July 14. 



V'enezuelan specimens examined (La Gaira and San Esteban) are P. 

 trinitatus, as stated by Barbour and Noble (Bull. Mus. of Comp. Zool., 

 LXin, pp. 401-402). This species can be distinguished from P. subpunc- 

 tatus by the fact that it either has a dark bar across the chest, or the throat, 

 chest and belly are dark, but there are other distinctions between the forms. 

 The only structural difference which the writer has found is in the rough- 

 ness of the skin of the dorsal surface. Over most of the body the skin is 

 smooth or slightly granular, but in the lumbar region it tends to be more 

 granular, and in P. trinitatus is raised into more or less numerous and 

 prominent warts. Of 20 specimens from Trinidad, 14 have distinct warts 

 in the lumbar region, and in 6 Trinidad specimens and 3 Venezuelan speci- 

 mens the warts are small, and few in number. Of 18 Santa Marta speci- 

 mens of P. subpunciatus, one has a few faint indications of warts, in others 

 the skin is granular or smooth. 



Notwithstanding a general similarity, the specimens from Trinidad and 

 Venezuela [P. trinitatus) can be distinguished from those from Santa 

 Marta {P. subpunciatus) by differences in the coloration. In the latter 

 the black or blackish brown lateral stripe is very distinct and is usually 

 bordered above by a light stripe which may extend around the snout, but 

 at any rate is usually well defined forward to the eye. In Trinidad and 

 Venezuelan specimens the dark line is less distinct and the light band is 

 also much less distinct and often absent. In every specimen of P. trinitatus, 

 except the very dark ones, the lateral dark band is widened or divided pos- 

 teriorly to the eye, involving from a fourth to three-fourths of the tympa- 

 num and reaching the limb insertion. In P. subpunctatus the black band 

 is a little widened on the neck and includes but the upper margin of the
