14 L. G. ANDERSSON, SOME NEW SPECIES OF SNAKES. 



five in contact with the elongate anterior chinshields, wtich 

 are as long as and broader than the posterior. 



The body slender, cylindrical, very long and narrow, 

 tapering in a long and thin tail. Scales in 15 rows, elongate 

 and narrow, on the anterior part of the body obliquely dis- 

 posed, all smooth, but striated. The median row enlarged. 

 Ventral shields 157, without keels and notches. Anal divided; 

 subcaudals 169 pairs. 



The groundcolour above påle brown, each scale with 

 numerous copper-coloured döts and stripes, beside which there 

 are greater black irregular dashes dispersely spread över the 

 body. Beneath the darker cojDper colour is the ground co- 

 lour, the shields all marbled with ligth and black. The 

 throat light, with a dark spöt on the middle of each shield. 

 Where the epidermis is löst, the snake is white with a tinge 

 of red and sprinkled with black. The head above dark brown, 

 speckled with black, beneath yellowish white. The iirst. 

 second and third upp er labials are brown with the inferior 

 anterior corners white, the fourth, fifth, and half the sixth 

 white with brown spöts, and half the sixth, the seventh and 

 the eighth brown. There is no dark streak behind the eye. 



In colour this species seems to agree very closely with 

 Leptophis cupreus (Cope), but dilFers in the want of the dark 

 streak behind the eye, the smooth scales, the single enlarged 

 vertebral row, and the not nmusually short hroad head». 

 From Leptophis depressirostris^ with which it agrees in the 

 smooth scales, it differ in the colour, the enlarged vertebral 

 row, eight upper labials etc. 



The specimen in question belongs to the collections, above 

 mentioned, received in 1862 from Dr. Touzet at Rio Janeiro, 

 wherefore Brasilia probably is the patria of the new species.
