The two following species appear to be new :— 



Cyclodus carinatus. 



Similar to C. gigns, and with the same elongate temporal shields ; 

 but the scales are larger, there being thirty-two in a series round 

 the body, and fifty in a longitudinal row between the axils of the 

 fore and hind limbs*. The median scales along the back are very 

 distinctly keeled, the keels forming slight longitudinal ridges along 

 the back of the tail. 



Brownish olive, with about ten narrow black bands across the back 

 of the trunk ; sides and belly marbled with black ; limbs black. 



Total length 18 inches, of which the tail measures 8 inches. 



Coluber holochrous. 



Scales smooth, without groove, in seventeen rows. Seven upper 

 labials; two anterior- and two posterior oculars. Uniform brownish 

 grey ; belly and the outer series 0/ scales dull yellowish. 



Body and tail moderately elongate, but slightly compressed. 

 Rostral shield broader than high, scarcely reaching to the upper 

 surface of the head ; anterior frontals not quite half as large as the 

 posterior ; vertical pentagonal, as broad as long, the lateral edges 

 being shorter than the anterior. Occipital shields moderate, slightly 

 notched behind. Nostrils wide, the suture between the two nasals 

 being very indistinct. Loreal large, longer than high ; two anterior 

 and two posterior oculars, the upper anteocular not being in contact 

 with the vertical. Seven upper labials, the third and fourth coming 

 into the orbit. Eight temporal shields in three transverse series ; 

 the two anterior temporals are somewhat elongate, and the upper of 

 them is in contact with both postooulars, the others are scale-like. 

 Eight lower labials, five of which are in contact with the chin-shields. 

 Ventral shields 20() ; anal entire ; subcaudals eighty-seven. There 



* Cychdiis gigas, from New Holland, has thirty-six series of scales round the 

 body, and fifty-seven or sixty between the fore and hind limbs.
