side, i)roocular and postnasal hcino- in contact. Garman mentions a 

 specimen in the musemn at Cam))ridg-e, Massachusetts, havin*;- tlie pre- 

 frontals fused on the median line. The normal number of supralal)ials 

 is 8, l)ut the Culebra specimen described has !> on oiu^ side. Meer- 

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

 specimens recorded) vary between 134 and llC, subcaudals betwecMi 79 



and S() pairs. 



IMifdf.—Thuti far this species has only l)een known from St. Thcmias 

 and St. John. During his visit to Cuhdn-a 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 Le'DnadopHs sfahh\ described above. 



Bemarl-s.—Tho only essential difference between Z. ,:.e!guus and 

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

 Altogether 1^9 specimens of both species have ])een examined and 

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