40 THE PROCEEDINGS OF THE LTNNEAN SOCIETY 



12. — Pappophis FLAVIGASTRA. 



Scales as in the last ; abdominal shields 264, subcaudals 94-94; 

 total length, 5 feet 2 inches ; tail, 11 inches ; length of head, 1| 

 inches ; width of head, 10 lines ; width of neck, 5 lines ; colour, 

 above pale olive brown, beneath yellow, getting darker towards 

 the tail. 



This species differs from the last not only in the number of the 

 abdominal and subcaudal shields and in co 1 oration, but it is pro- 

 portionally much narrower in the head and shorter in the tail. 

 The loreal shield also is more square. The ventral plates are dis- 

 tinctly keeled, but the tail is almost quite cylindrical. 



One specimen was obtained at Katow. 



VENOMOUS SNAKES. 



13. — DlEMENIA PAPUENSIS. 



Body elongate and slender ; head long, narrow, flat between 

 the eyes and rather convex in front ; scales in 15 rows ; anal 

 shield bifid ; abdominal shields 225, subcaudals 88-88 ; total 

 length, 5 feet 6 inches ; tail, 15 inches ; praeocular shield deeply 

 grooved; vertical shield elougate and narrow; superciliaries over- 

 lapping the eye. The colour of the head is pale olive, with the 

 under side to the lower edge of the upper labial shields, yellow, 

 and with numerous brown spots on the vertical, superciliary and 

 occipital shields ; the scales of the body are of a dark nitid 

 brown, the abdominal shields are of a light slate colour, and the 

 subcaudals pale brownish yellow. 



This species seems to come near D. Psammophis ; indeed I 

 should probably have taken it for one had I not found that the 

 specimens of D. Psammophis in the Australian Museum are 

 undoubtedly distinct. 



The collection contains only one specimen, and the exact loca- 

 lity of its capture is not mentioned ; it is simply labelled New 

 Guinea. I think it must have been got at Hall Sound. 



14. — Acanthophis laevis. 

 All the head shields and scales of the body quite smooth ; 

 superciliary shields much elevated over the eyes; only one
