This is the genus Dipsas as understood by Giinther 1. c. We have, however, 

 not followed this author in the application of a name, since that employed by 

 him was given to auother and allied form, long previously. Some time subse- 

 quent to the first use of Dipsas,*the present genus received the barbarous ap- 

 pellation of Boiga (!). This we would gladly resign in favor of Triglyphodon 

 Dume'ril, but dates are inexorable. Vae serioribus.

 Hallow, loc. cit. p. 60, 1857. Our specimens of this fine and interesting dipsa- 

 dien agree very nearly with the description and figures of Fischer. The two 

 preoculars and divided anal shield are striking characters,* and it exhibits a 

 relationship to Ophiodon Dum. and Bibr. in its elongate anterior maxillaries, 

 On these peculiarities, but especially from the fact that our specimens have but 

 a single grooved tooth on each side, Dr. Hallowell proposed his genus Toxico- 

 dryas 5 . The latter character is, however, inconstant, for Fischer states that his 

 specimen had two such teeth on each side, and Dumeril, that his had three. 

 The elongation of the anterior maxillary and palatine teeth does not appear 

 to us sufficiently distinctive to afford generic characters, nor are the other 

 peculiarities of sufficient importance.

 in this species, also, but one groved superior maxillary.

This genus unites the short, flat head of the true Dipsas, (Leptognathus D. 

 & B. Gthr.) with the dentition of the preceding genus. The tail is very long and 

 slender.
