LeptojDhis liocercv.s (non Wied), Bocourt, Miss. Sc. Mex., Eept. 

 p. 823, pi. Ixii. fig. 3 (1895). 



Eostral much broader than deep, just visible from above ; inter- 

 nasals shorter than the praefrontals ; frontal once and one third 

 as long as broad, as long as its distance from the rostral or the 

 end of the snout, as long as or a little shorter than the parietals ; 

 nasal elongate, divided ; no loreal ; prsefrontal in contact with 

 labials ; one praeocular, in contact with or narrowly separated 

 from the frontal; two postoculars ; temporals 1 + 2; nine upper 

 labials, fifth and sixth entering the eye ; five or six lower labials 

 in contact with the anterior chin-shields, which are shorter than 

 the posterior. Scales in 15 rows, all except the outer row strongly 

 keeled ; scales on the neck and tail keeled. Ventrals feebly angu- 

 late laterally, 159-168 ; anal divided ; subcaudals 165-172. Bright 

 green above, closely speckled all over with black ; the keels on the 

 scales black ; a black streak behind the eye ; upper lip and lower 

 parts pale green. 



Total length 1600 millim. ; tail 620.

 Paramba. 



36. Ateacttjs multicincttts Jan. 



Paramba. 



The specimens belong to the form figured by Jan as Eahdosoma 

 hadium, yar. multicinctum. 1 think they deserve specific distinction 

 from A. haclius, as first suggested to me by my friend Count 

 Peracca, owing to the higher number of ventral shields (177-182) 

 and the shape of the rostral, which is as deep as broad. No spots 

 whatever on the belly.
