* Amphibians and Reptiles of Santa Marta 65 



having six lower labials. The diameter of the body is contained 4i>^ times 

 in the length, the length of the tail 13 2/3 times. 



Bpicrates cenchria (Linnaeus). — Fundacion. A single specimen taken 

 near Fundacion was secured from a native. 



Constrictor constrictor (Linnaeus). — San Lorenzo, 2,200 feet. Taken 

 in the forest. Reported as frequently seen at an elevation of about 2,200 

 feet and lower. 



The characters given below are those of C. constrictor, not C. impera- 

 tor. Dorsal scale rows 81, supraoculars 24, ventrals 247, subcaudals 55, 

 rows of scales across forehead 18, dark cross-bands 20. 



Drymobius hoddaertii (Sentzen). — Two hundred feet above Bolivar 

 (observed) to 5,500 feet, San Lorenzo; Valencia; Palomina and La Con- 

 cepcion (W. W. Brown). A common ground snake in the wet forest on 

 San Lorenzo ; generally distributed above 2,200 feet, below this altitude only 

 seen in ravines in the dry forest. At Valencia found in the flood-plain 

 forest. The only food found in the stomachs examined was frogs. (PI. 

 VIII, fig. 2.) 



Drymobius rhombifcr (Giinther). — San Lorenzo from 3,000 feet to 

 5.500 feet; Don Diego (M. A. Carriker) ; Palomina and La Concepcion 

 (W. W. Brown). A common ground snake in the wet forest. One speci- 

 men was taken from an egg in the stomach of a Lachesis lance olatus. The 

 stomachs examined contained frogs, Prosthcrapis snbpnnctaius, and Eleu- 

 therodactylus sp. (PI. X, fig. 2.) 



The differences in the number of subcaudals is great, the extremes being 

 84 and 103. 



Phrynonax poecilonotits (Giinther). — San Lorenzo, 4,500 feet; Don 

 Diego (AI. W. Carriker). The specimen taken on San Lorenzo was in a 

 coffee tree ; the one from Don Diego was found on the ground in a dense 

 cacao grove. The San Lorenzo specimen had eaten a partly fledged bird. 



Peracca^® has shown that the characters used to distinguish P. poecilo- 

 notus, liinitlatiis, fa-sciatus, and guenthcri are not sufficient. The Santa 

 Marta Mountains specimens are like those hitherto referred to P. fasciatus 

 in that the dorsal scales are weakly keeled, the preocular is in contact or 

 narrowly separated from the frontal, and the upper labials are eight. The 

 dorsal scale formula is 21-19-17-15-13 and 2i-23-2i-i9-i'7-i5-i3-(ii), 

 (PI. IX, fig. 2.) 



Drymar^chon corias melaniirus (Dumeril and Bibron). — San Lorenzo, 

 600 feet to 4,000 feet ; La Concepcion, Palomina, and "Macotama or San 

 Miguel, 6,000-8,000 feet" (W. W. Brown). On San Lorenzo found in the 

 wet forest, and although but few specimens were seen, the number of cast 

 skins would indicate that the species occurs in some numbers. 



Chironius carinatiis ( Linnaeus ).^^ — Santa Marta; Palomina and La 



"''•Bol Mus. Torino, No. 253, pp. 6-8. 



"^ Fitzinger Syst. Rept., pp. 2Q and .31, specifically designates Linne's Coluber 

 carvmtus as the type of his genus Chironius. Dr. Leonhard Stejneger {in lift.) has 

 called my attention to the fact that C. cariiiatus has Coluber chiroMus Donndorf, 

 Zool. Beytr., vol. 3, p. 2og, as a synonym and is consequently type by tautonymy.
