tury. It has sadly deteriorated, but still shows signs of former opulence. 

 It cannot be more than 500 to 600 feet above sea-level. 



Victoria, La. A coffee plantation on the north slopes of San Lorenzo, 

 adjoining the hacienda Cincinnati on the east and north. There is also 

 another plantation of the same name near Dibulla, on the sea coast, where 

 the writer worked some years ago. 



Vista Nievc. A new plantation estabhshed by the writer a few years 

 ago, lying on the south slopes of San Lorenzo, with lands reaching from 

 3,000 to 8,000 feet. A region of heavy mountain forest. It is reached by 

 the same road leading to the hacienda Cincinnati, passing through that plan- 

 tation and continuing on around the mountain about four miles. 



The ReptieE-Amphibian Fauna and its Geographical Relations 



Snuunary of the Knozvn Fauna: But few zoologists have visited the 

 Santa Marta range. Previous to 1913 only two collectors seem to have 

 collected reptiles and amphibians in the mountains, W. W. Brown for the 

 Museum of Comparative Zoology of Harvard College, and H. H. Smith for 

 the Carnegie Museum, and these men gave particular attention to other 

 groups. The published records are those of the Museum of Zoology of the 

 University of Michigan and a paper by Lawrence Griflfen- which includes 

 the snakes obtained by Smith. 



The writer has had the material collected by Brown and Rehn and 

 Hebard (in 1920), through the courtesy of the Museum of Comparative 

 Zoology and the Academy of Natural Sciences of Philadelphia, besides the 

 specimens obtained by the expeditions of the University of Michigan, but 

 he has been able to examine but two of the specimens of the Smith collec- 

 tion. The material studied represents 93 species and includes all but seven 

 of the thirty-one snakes recorded by Griff en, if from his list are excluded 

 four species: Leptophis rostralis, of doubtful locality; Bpicrates cenchria 

 fusca, a color variety of doubtful validity ; Micrurus cohimhianus, a syno- 

 nym , and Atraqtiis baditis, which is evidently identical with the species 

 referred to in this paper as Atractus irridescens. The seven species listed 

 by Griffen which have not been seen are Helminthophis bondensis. Boa 

 cooki, Leptophis hoeourti, Spllotes piillatns, Oxyhclis fulgidiis, Rhinostoma 

 gtiianense, Micrurus corallinus. 



It is very clear that much more field work must be done before the 

 components of the fauna, the habitats, and the exact distribution of many 

 of the species are accurately known, particularly since the records of Brown 

 and Smith cannot be used for detailed studies. (See page 15.) It is 

 believed, however, that the data obtained by the University of Michigan 

 expeditions is sufficiently detailed to permit certain deductions to be made. 

 An attempt was made to work out the breeding habits of the species, when 

 these were likely to throw light on the ■ distribution, and much time was 

 spent in the field to get representatives of every species in each habitat and 

 region and to determine the limits of range of each species. These data
