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.
