 blackish, without spectacle-mark ; lower surface of neck white, 

 followed by a black cross-band, and with an azygous black spot ante- 

 riorly and one or two on each side. 23 or 25 scales across the neck, 

 17 or 19 across the middle of the body. Ventrals 183-192; sub- 

 caudals 50-52 pairs. 



This variety, which is closely allied to Cantor's var. niffra, connects 

 the typical iV. tripudians with Reinwardt's N. sputatrix.
