424 PROCEEDINGS OF THE ACADEMY OF [1894. 



zoid; oculars 1-2; temporals 0-2. Interuasal mutual contact short; 

 parietals short, wide, truncate posteriorly, bounding both postoculars 

 posteriorly. Pregenials bounded by four labials, a little longer than 

 postgenials. Gastrosteges, 164, obtusely angulated ; anal entire; 

 urosteges, 36. 



Color above yellowish-brown; below brownish-yellow. No marks 

 on the head; on the superior surface of the body there are indistinct 

 cross bars, which consist of the dark edges of scales, at intervals of 

 two and three scales; they are not continued on the tail. Total 

 length, 400 mm. ; of tail, 58 mm. 



This species probably resembles the H. swiiihonis Gthr. (Rept. 

 Brit. India, p. 215, PI. XX, fig. E. ); but it differs materially in 

 having but one preocular; in the absence of an anterior temporal ; 

 in the contact of the anterior genial with four labials, and in the 

 longer postgenial. The color above is pale brown, not olive. 



The hemipenis of this species is smooth, and without spines, 

 flounces, or ruches; agreeing with that of the 11. ancorus, as figured 

 by me in the "American Naturalist," 1894, Plate XXVII, fig. 4. 

 These characters refer the genus to the Calamariiuse, with Oligodon, 

 etc. (See "American Naturalist,'" 1893, p. 480.) A character of 

 subordinate value seen in the hemipenis of H. ancorus, which is not 

 present in H. dolleyanus, is a shallow pocket on each side of the sul- 

 cus spermaticus. 



There is a rudimental right lung 5 mm. in length, communicating 

 with the trachea by foramen. No tracheal lung. 



This species is dedicated to my friend, the distinguished zoologist. 

 Dr. Chas. S. Dolley.

A single male specimen gives me an opportunity of determining 

 the position of this curious genus. With some external resemblance 

 to the American Leptognathus, it combines not dissimilar dentition 

 and squamation; it is to be presumed that the habits are not dis- 

 similar. Examination of the hemipenis shows, however, that it is 

 really related to the Calamariinte, and to Slmotes. This organ is 

 without spines or ruches, and has only flat obtuse papillre on the 

 middle third of its length, the distal portion being smooth, with a 

 few feeble papilke at the apex. It is deeply bifurcate, the basal 

 portion being quite short. At the summit of the middle papillose
