TABLE 1.-COMPARISON OF THREE OF Enulius WITH BAY ISLAND SPECIMEN.

Bay Island Characters flavitorques sclateri oligostichus Specimen

Smith et al. (1957) pointed out, flavitorques from (to which they apply the subspecific name flavitorques) most often have a light collar, which Mexican specimens lack. They cited Dunn's (1938) mention of collarless specimens from Panama, , and Guate- mala (one specimen from each country). All 18 specimens of flavi- torques examined from mainland have a light collar. The ventral counts of 165 for the Bay Island specimen is one lower than the range-wide minimum for flavitorques, but 11 male flavitorques from mainland Honduras have a ventral range of 178 to 198, Y= 184.1. Even though there are definite differences in numbers of ventrals and subcaudals between the Bay Islands specimen and the material from the Honduran mainland, we believe that when additional specimens from the islands become available, they will show an overlap in these counts with those of flavitorques populations outside of Honduras. An ana- logous situation exists in Oxybelis aeneus (q.v.). Meanwhile, until additional island material becomes available, we prefer to allocate this specimen to flavitorques. This specimen was found crawling in low vegetation on a roadcut.

SPECIMENS EXAMINED.-Isla de Roatin: 0.5-1.5 mi N Roatin (LSUMZ 22382).

Leptophis mexicanus Dumbril and Bibron Two specimens of this are known from Isla de Utila, a female (CM 29003) collected 18 April 1948 by Twomey, and a male (UF 28401) we collected 13 August 1969 during the morning on the ground in a banana clearing. The two specimens exhibit the coloration typical of L. m. mexicanus and scutellational features fall within the ranges Oliver (1948) gave for this subspecies. Except for the subcaudal count of the male, the ventral and subcaudal counts fall within the range of 14 specimens
