 a little longer than one annulus ; red scales tipped with black ;

* Dr. Giinther has noticed (Biol. C.-Am., Eept. p. 166) that the groove on 

 the posterior maxillary tooth ia absent in these specimens. At his suggestion 

 one of the specimens has been handed over to Mr. Gr. S. West, who is now 

 engaged in investigating the poison-glands of Opisthoglyphoua Snakes, and I 

 have been favoured with the following report : — " The buccal glands of Erythro- 

 lamprus isscttlapii and of the Erythrolam/prus from Nicaragua are precisely 

 identical in disposition and extent, and they have the same structure. The 

 maxillse only differ in the former possessing on the two posterior slightly 

 larger teeth a very shallow groove, which does not extend more than two-thirds 

 the way to the apex of the tooth."
