I have now tlie pleasure of describing another snake of the 

 same group, but of much larger size, and to connect with it 

 the name of Sir W. Ingram. 



Diemenia ingravii. 



Eye rather small, its diameter equal to its distance from 

 the oral border and one third the length of the snout. Snout 

 rounded, strongly projecting beyond the lower jaw, with 

 feeble canthus. Rostral broadtir than deep, the portion 

 visible from above measuring about one half its distance 

 from the frontal ; internasals a little shorter than tlie pras- 

 frontals ; frontal bell-shaped, as broad as the supraocular, 

 once and two thirds as long as broad, as long as its distance 

 from the end of the snout, tiiree fourths the length of the 

 parietals ; nasal divided, separated from the single, deeply 

 grooved prasocular ; two postoculars ; temporals l-|-2; six 

 upper labials, second in contact with the prsefrontal, tliird and 

 fourth entering the eye, fifth narrowly separated from the 

 parietal, sixth very large ; four lower labials in contact with 

 the anterior chin-shields, which are larger tiian the posterior. 

 Scales in 17 rows, on the body, in 21 on the neck. Ventrala 

 205 ; anal divided ; subcaudals 65 pairs. Uniform dark 

 brown above and on the outer ends of the ventral shields, 

 some of tiie scales lighter in the centre, yellow beneath. 



Total length 1510 mm. ; tail 240. 



A single specimen from Alexandria. 



LI. — Note on tlie Type Specimen of a Blind Snake, 

 Helminthophis vvilderi (Garman), from Brazil. By A. 

 G, Hammar. 



In the course of studies of South-American snakes in the 

 Museum of Cornell University, I had the opportunity to 

 examine the type specimens of Tiiphlops wi/deri, Garm. 

 Since this species is not recognized in the literature, and has 

 been referred to in Boulenger's ' Catalogue of Snakes,' i. p. 7, 

 in a footnote, as insufficiently characterized, I have made 

 a careful study of the specimens and give below a new 

 description, which will bring it into its proper systematic 

 position. 



l)ue to the presence of two very large prefrontals, Typlilops 

 wilderi, Garm., must be included under the genus lldinm- 

 thophis, Peters, Boulenger, Cat. of Snakjs, i. p. 4.
