PSEUDAPISTOCALAMUS, gen. nov. 



This genus is allied to Apistocalamus, Blgr., and Pseud- 

 elaps (D. & B.), Blgr. 



Maxillary extending forwards fully as far as the palatines, 

 with two grooved teeth, anteriorly followed by four grooved 

 teeth, gradually, but feebly, decreasing in length. Head 

 small, depressed, hardly distinct from neck. Eye very small, 

 with round pupil. Nostril pierced in a single nasal, but the 

 margin of the latter bordering the first labial and the inter- 

 nasal comparatively narrow ; a large prseocular, in contact 

 with the single nasal. Body cylindrical ; scales smooth, in 

 15 rows; ventrals rounded. Tail short; subcaudals in two 

 rows. 



Pseudapistocalamus Nymani *, sp. n. 



Snout short, bluntly rounded. Kostral broader than deep, 

 visible from above, but the visible portion hardly one fifth of 

 its distance from the frontal ; internasals rather small, about 

 half as long as the prefrontals. Prefrontals not quite so 

 long as the frontal. Frontal almost as broad as long, almost 

 as long as its distance from the rostral, much shorter than 

 the parietals ; prEeocular single, longer than deep, forming a 

 suture with the nasal. Normally two postoculars, upper 

 much larger than lower, sometimes both fused to one. Tem- 

 porals 1 + 2 ; six (or seven) upper labials, third and fourth 

 entering the eye, sixth largest, sometimes divided ; five lower 

 labials, three in contact with the anterior chin-shields; poste- 

 rior chin- shields smaller, more or less separated by a scale, 

 which sometimes reaches the anterior chin-shields, sometimes
