Neiv genera and species : — 
Prof. Reinhardt, Overs. Yid. Selsk. Forhandl. Kjdbenh. (1863, 
December), has discovered a very interesting new genus of 
snakes, which is provided with an apparatus of gular teeth simi- 
lar to that of the African Dasypeltis. He names it Elachistodon, 
the teeth in the jaws and on the palate being minute and few in 
number. The maxillary has one or two small grooved teeth 
behind. Scales smooth, in fifteen series, those of the vertebral 
series being enlarged, bexagonal. Two nasals; loreal oblong, 
entering the orbit ; one praeorbital. — Elachistodon westermanni, 
from Rungpore ; tlie head and the dentition are figured. Rein- 
hardt refers this snake to the DasypeltidcCj whilst Gunther (Rept. 
Brit. Ind. p. 444) would prefer to place it as the type of a dis- 
tinct group in the family of Coluhrid(E. 
Kynrpho}^hidimn is a new genus proposed by Giinther, Rept. Brit. Ind. 
p. 235; it is allied to Odontomtfs, from which it differs in the dentition, the 
three posterior maxillary teeth being very strong and trenchant ; it has coni- 
cal prominences on the base of the skull, reminding us of the vertebral teeth 
of T>amfpdtis and Elachistodon. — N. macidatum, pi. 19. fig. H. — The Recorder 
may add that he has lately received a second example from the East Indian 
Archipelago.
