Plectrurus trilineatus (Bedd.). 

 This is another very interesting addition made by Capt. 

 Beddome to the family of TJropeltidcB. It differs from Flec- 

 trurus proper, and, like MelanopMdium^ approaches the Cala- 

 maridce. The head is remarkably flattened, obtusely rounded 

 in front ; no mental groove ; tail comparatively long, with a 

 distinct double series of subcaudals, terminating in a horny 

 shield, the edge of which is horizontal, and not vertical as in 

 Plectrurus ; the shield is one-, and not two-pointed. I propose 

 the generic name Platyplectrurus for it. 



Silyhura grandis. 



Rhinophis grandis, Beddome. 



This snake is more closely allied to Silyhura ocellata than 

 to RhinopMs pidneyensis^ to which it has been compared by 

 its discoverer. However, these species show that the distinc- 

 tion between Silyhura and RJmiophis is scarcely generic, and 

 that they may be united before long. 



Xenocalamus (g. n. Calamar.). 



Body cylindrical, elongate ; tail short ; head long, depressed, 

 narrower than the neck. Eye extremely small, with round 

 pupil ; rostral large, conically produced, the mouth being quite 

 at the lower side of the head ; one pair of frontals ; vertical 

 enormous ,* occipitals small ; nostril between two shields ; 

 loreal none ; scales smooth, without apical groove, in seven- 

 teen series ; anal and subcaudals paired. Maxillary teeth few 

 in number, smooth ; palate without teeth.
