548 CENSUS OF AUSTRALIAN SNAKES, 



CENSUS OF AUSTRALIAN SNAKES WITH DESCRIP- 

 TIONS OF TWO NEW SPECIES. 



By William Macleay, F.L.S., &c. 



In a very interesting collection of mammals and reptiles lately 

 sent to me by J. A. Boyd, Esq., of Ripple Creek, Ingham, in 

 Northern Queensland, I have found two species of Snakes not 

 hitherto recorded. Their descriptions are as follows : — 



DlPSAS BOYBII. 



Ventral plates 252 



Sub-caudal 90/90 



Anal plate entire. 



Scales in 19 rows 



Total length 3 feet 11 inches. 



Tail 9 J inches. 



Form slender and compressed behind the head, the rest of the 

 body move robust and less compressed that in D. fusca. Head 

 large, broad, much broader than the neck. Head shields much as 

 in D. fusca, the anterior ocular large, intervening between the 

 superciliary and the posterior fiontals ; the two posterior oculars 

 very small ; ten upper labials, the fourth, fifth and sixth touching 

 the orbit ; superciliaries much narrowed in front, triangular. 

 Mouth much curved. 



The colour is of a tolerably uniform dark olive brown, paler and 

 more yellowish on the belly.
