This species, with the LiopMs bicinctus Dura. Bibr., belongs to a 

 genus distinct from both Liophis and Xenodon. Its characters are : Den- 

 tition diacranterian ; anal acute, entire ; a circle of scales, with the super- 

 ciliary surrounding the eye ; scales smooth. Professor .Jan has already 

 distinguished the genus, but has given it a name (Lejosophis) which, when 

 properly spelled (Liophis), is one which has already been used. I, there- 

 fore, give it another name, as above.

The Naturalist Brazilian Exploring Expedition, under the direction of 

 Mr. Herbert H. Smith, commenced its work in the province of Rio Grande 

 do Sul. The principal collections were made at Sao Joao do Monte Negro. 

 The present catalogue shows that the snake-fauna is not poor, and it adds 

 some important points in the history of the geographical distribution of 

 the Batrachia and Reptilia of South America. A number of the species in 

 the collection are sent for the first time to the United States.

The normal coloration is presented by numerous specimens. Another one 

 is brown, with three darker, brown dorsal bauds, a median narrow one 

 and two lateral wider ones, with indistinct superior margins above the 

 light border of the lateral brown band. The hind-legs are also cross- 

 banded, a character not found in the normal form.
