HERPETOLOGY OF PORTO RICO.

side, preocular and postnasal being - in contact. Garman mentions a 

 specimen in the museum at Cambridge, Massachusetts, having the pre- 

 frontals fused on the median line. The normal number of supralabials 

 is 8, but tin 1 Culebra specimen described has 9 on one side. Meer- 

 warth describes a similar specimen from St. Thomas. Ventrals (in 19 

 specimens recorded) vary between 134 and 14*>, subeaudals between 79 

 and 86 pairs. 



Habitat. — Thus far this species has only been known from St. Thomas 

 and St. John. During his visit to Culebra Island Mr. A. B. Baker 

 secured a single specimen there. The probability is that it will also 

 be found on Vieques. It does not occur in Porto Rico proper, where 

 its place is taken by Leimadvjf/us stahlt, described above. 



Remarks. — The only essential difference between L. exiguus and 

 L. stahli seems to be the lower number of ventrals in the former. 

 Altogether 29 specimens of both species have been examined and 

 recorded, and in these the difference is marked and constant.
