* Dr. Giinther has noticed (Biol. C.-Am., Rept. p. 166) that the groove on 
the posterior maxillary tooth is absent in these specimens. At his suggestion 
one of the specimens has been handed over to Mr. G. 8S. West, who is now 
ane investigating the poison-glands of Opisthoglyphous Snakes, and I 
have favoured with the following report "The buecal glands of Yrythro- 
lamprus e@sculapii and of the Lrythrolamprus from Nicaragua are precisely 
identical in disposition and extent, and they have the same structure. The 
maxille only differ in the former sing on the two posterior ar A 
larger teeth a very shallow groove, which does not extend more than two-thi 
the way to the apex of the tooth.”
