Amphip.ians and Reptiles of Santa Marta 67 



Imantodes cenchoa (Linnaeus). — A single specimen from Aracataca 

 (Rehn and Hebard). 



Leptodeira albofusca (Lacepede). — Bolivar; Fundacion; Fonseca. 

 Found near irrigation ditch at Bolivar, about a marsh at Fundacion, and 

 in the flood-plain forest at Fonseca. A nocturnal species usually found 

 under logs, under the scales of palms, etc., during the day. One specimen 

 had eaten a frog. 



In six specimens the dorsal scale formula is 19-21-19-17-15, and in 

 three it is 21-19-17. For remarks on the relations of this form and Z,. 

 annulata see infra. 



Leptodeira anuulata (Linngeus). — Arroyo de Arenas. A single speci- 

 men taken at night on a tree trunk in the flood-plain forest. 



The dorsal scale row formula is 19-17-15. The ground color is brown- 

 ish white with numerous broad, black-edged, brownish spots about one and 

 one-half scales apart descending to the first row of scales. 



After examining a series of specimens from South America, Grififen*^ 

 has arrived at the conclusion that L. annulata is a synonym of L. albofusca. 

 The writer does not concur in this opinion. It is true that many of the 

 characters do not, because of overlapping, indicate two forms ; but in the 

 number of dorsal scale rows there is an apparent difference at least which 

 is not brought out in Griffen's counts. When two species are as mvich alike 

 as these two, the maximum number of scale rows means little. It is the 

 average for the entire body that is significant. In L. albofusca the scales 

 are usually 19-21-19-17-15 or 21-19-17 in the females and usually 19-17- 

 I5"(i3) i" t^ie males. From the number of specimens of L. annulata 

 recorded with 19 rows the usual formula is evidently 19- 17- 15. The two 

 forms can be considered identical in the dorsal lepidosis only if it is revealed 

 after a study of large series that the scale formulae are the same. 



Clelia petola (Linnaeus). — Don Diego (M. A. Carriker) ; La Concep- 

 cion (W. W. Brown). The specimen taken at Don Diego was on the 

 ground in a cacao plantation. 



In all of the specimens the dorsal coloration is principally red, the 

 tip of each scale is tipped with black, and the black cross bars are present 

 only on the anterior one-third of the bod}^ and distinct only on the anterior 

 one-fourth. 



Oxybelis acicminatus (Wied). — Bolivar to 800 feet, San Lorenzo; 

 Fundacion ; Arroyo de Arenas ; "Macotama or San Miguel, 6,000-8,000 

 feet" (W. W. Brown). Common in trees and bushes at Bolivar, and taken 

 in the same habitat at Fundacion and Arroyo de Arenas. Known locally 

 as the bejuca snake. (PI. X. fig. i.) 



The scale formula is 17-15-13, 15-17-15-13, and 15-17-15-13-11. 



Brythrolamprus acsculapii (Linnaeus). — San Lorenzo from 4,500 to 

 6,000 feet; Palomina, La Concepcion, Pueblo Viejo at 8,000 feet (W. W. 

 Brown). A common ground form in the wet forest. A specimen taken 

 on San Lorenzo had eaten two small individuals of Atractns irridescens.
