430 bulletin: museum of comparative zoology. 



Variation: — The female and the young are very similar to the male 

 in coloration; but, although the pattern is the same, the colors are 

 much richer. In the female the dark blotches of the sides are more 

 numerous and confluent than those of the male, while in the young 

 these dark areas are so much increased that they often surround the 

 light spots and make a dark background for them as for example in 

 the specimen M. C. Z. 7334 (same data as above). Ventrally, the 

 young have a wash of turquoise-blue varying to yellow instead of the 

 checker pattern. 



Remarks: — The description was taken from a full grown adult male 

 that measures eighty-nine millimeters from snout to vent. 



Habitat: — Confined to Jamaica where it has become rare, because 

 of the introduced mongoose.
