Boulenger ^ makes Leiocejyhalus raviceps Cope a synonym of this 

 species. I have the types of Cope's species (No. 4162 U.S.N.M.) 

 collected by Charles Wright in "Eastern Cuba" before me and can 

 affirm that L. ravice'ps is a very distinct species and that the two 

 have absolutely nothing to do with each other. In fact, they belong 

 to different sections of the genus. Thus L. cuhensis has three pairs 

 of prefrontals (exclusive of intemasals) while L. raviceps has only

two, the posterior pair being exceedingly large. Moreover, L 

 raviceps is distinguished by much smaller scales, about 20 corre- 

 sponding to a head length against about 12 in L. cuhensis. It is 

 related to L. loxogrammus, but not to L. cuhensis. 



The latter is widely distributed and was collected by Palmer and 

 Riley at San Diego de los Banos, at Pinar del Rio, El Guam^,Caimito, 

 Marianao, and on the Isle of Pines at Nueva Gerona. Also by 

 Palmer in 1902 at Moro.

According to the old label in the bottle containing the types of 

 this species in the United States National Museum, they came from 

 Monte Verde in Eastern Cuba. The species seems to be confined 

 to that portion of the island, as it was not collected by Palmer and
