 frontal rather small. Two posterior frontals wliicli enter the orbit. 

 Upper labials five. Pupil round. 



F. BENGALENSIS, U. S. 



Head not very distinct from body, rather ovate and elongate, rather 

 narrowed in front. Nostril almost dividing a small nasal (perhaps 

 two small nasals). Loreal one, small, squarish. Ante-ocular very 

 elongate. Upper labials five. The first very small, second and third 

 enter the orbit, fourth and fifth large, increasing in size regularly from 

 the first backwards. Anal bifid. Three undivided sub-caudals, the others 

 divided. 



a. Type specimen. Parisnath. A. Grote, Esq. 



This species approaches the Ceylonese genus Haplocercus, but differs 

 too materially to be considered a second species, and I have therefore 

 formed a new genus for its reception, bearing the name of the late 

 eminent Palaeontologist whose loss is still so fresh amongst us. 



BLYTHIA, GEN. NOV. 



Scales smooth in thirteen rows. Loreal none. Ante-ocular none, 

 both replaced by, a very large posterior frontal. Pupil round, sub- 

 caudals bifid. 



B. RETICULATA, Blyth. 



Calamaria reticulata^ Bhjth^ J. A. S., XXIII. 



Nostril in a small oblong shield. Frontals two pairs, anterior small ; 

 posterior very large. Vertical and superciliary moderate or smallish. 

 Posterior frontal forms a suture with the nasal, second and third upper 

 labials, the superciliary and vertical which has an obtuse angle in 

 front. Upper labials six. First very small ; third and fourth enter the 

 orbit; sixth largest. 



Occipitals large; lower labials five; 1st moderate, 2nd and 3rd small, 

 4th large, 5th band-like, narrow. The iirst lower labials form a suture, 

 and are followed by a pair of very large chin shields which are again 

 followed by a pair of small ones, the suture falling in the centre of 

 the 4th lower labial. Anal bilid.* Tail round, short.
