88 AMARAL — NEW GENERA AND SPECIES OF SNAKES [^ol^vm' 



No. 346, adult d\ sent alive from the locality Guayuvira, State of Sao 

 Paulo, Brazil, by Mr. Antonio Azevedo da Silva Junior, in January, 1914; 

 subcaudals, 45/45; total length, 560 mm.; tail, 75 mm. 



No. 3006, young, without any data; subcaudals, 61/61; total length, 

 355 mm.; tail, 57 mm. 



Rhadinaea brazili, which is named in honor of Dr. Vital 

 Brazil, former director of the Institute de Butantan, is closely 

 allied to Rhadinaea cobella (L.), from which it differs in the num- 

 ber of maxillary teeth, in color and markings, shape and size 

 of the frontal shield, and much higher number of ventrals. 



During a careful study which I have been making of the speci- 

 mens of Brazilian snakes, existing either in Brazil in the collec- 

 tions of the Museu Paraense, Museu Rocha of Ceara, Medical 

 School of Bahia, Medical School of Rio, Instituto Oswaldo 

 Cruz, Museu Nacional, Museu Paulista and Instituto de Butan- 

 tan, or in those of the Museum of Comparative Zoology and 

 others in this country, where I am now continuing my work, I 

 have been able not only to corroborate Miss J. B. Proctor's l 

 recent description of the new genus Sordellina, but to add a new 

 species to it. 



Sordellina pauloensis sp. no v. 



Head scarcely distinct from neck; eye small, with round pupil; body 

 cylindrical; end of tail conical, sharply pointed. Rostral about twice 

 as broad as deep, slightly visible from above; nasal semi-divided; inter- 

 nasals triangular, shorter than the praefrontals; praefrontals about twice 

 as broad as long; frontal a little longer than broad, twice as broad as the 

 supraocular, a little longer than its distance from the end of the snout, 

 much shorter than the parietals; loreal as long as deep; a large praeocular 

 reaching the upper surface of the head but separated from the frontal; 2 

 postoculars, the upper large, deeper than long; temporals, 1+2, the an- 

 terior about twice as long as deep; 8 upper labials, 4th and 5th entering
