524 A Collection of Mammalia, fyc.from Cherra Punji. [No. 6. 



5. Trigonocephaly gramineus, (Shaw). Young, 13 in. long, 

 of the Malayan variety with defined whitish lateral line. From 

 Sylhet. This small individual had bitten a labouring man/ but the 

 wound merely caused a painful swelling in the arm, which, however, did 

 not prevent the patient from returning to his work after a few hours ; 

 i. e. in the afternoon of the day during which he was bitten in the 

 course of the morning. This agrees with the remarks upon the venom of 

 three species of Trigonocephaly in J. A. S. XVI, 1044 et seq.* 



[We may here describe the following remarkable Bat, purchased 

 with a miscellaneous collection made at Darjiling. 



Lasiurus PEARSONII, Horsfield.f Length about 3J in., of which 

 the tail measures 1^ in., having its extreme tip exserted. Head 

 f in. Ears (posteriorly) \ in. ; and about 1^ in. from tip to tip. 

 Expanse about 13 in. Fore-arm 1 J in. : tarse f in. Head broad and 

 short : the ears broad, subovate, widely separated apart ; and the 

 tragus small, narrow and elongated. Teeth very robust ; the grinders 

 antero-posteriorly compressed, with the carnassiez contiguous to the 

 canine above and below, and the canines less elongated than in the 

 Nycticeji : there are four incisors above, of which the outer or lateral 

 are much smaller than the others. Fur soft and extremely dense, of 

 a uniform rufous-brown above and dingy greyish below, with conspi- 

 cuous hoary tips a little curling, more especially upon the head, 

 shoulders, and breast. The membranes are dusky, and the alar is 

 attached to the base of the outer hind-toe. The lateral membranes 

 near the body, and the whole interfemoral, are somewhat plentifully 

 covered with brownish-rufous fur, more scant on the interfemoral, and 

 very dense at the base of the tail above, being continued throughout 

 its length, and also along the hind-limbs, with the feet and calcanea. 

 Excepting in having two pairs of upper incisors, this species seems to 

 agree generically with the Lasiuri, Rafin., of N. America, or Vesp. 

 pruinosus and V. ruftjs (v. noveboracensis), auctorum]. 



* Notes by Mr. Frith. " The man was bitten, as above mentioned, at about 

 10 a. m. ; and when I saw him, at about 4 p. m., he was at his work, and the 

 swelling (which had been somewhat considerable) had by that time almost subsided. 



"As regards Talpa leucura (p. 518), I do not say that it may not inhabit the 

 valleys or lower lands of Cherra, that is to say, at the foot of the hills. The Kha- 

 sias state that they never met with it there ; but some of them at once recognised 

 the animal as being like one found about two or three days' distance in the interior, 

 but which they stated to be of a white colour." 



We should here add that Mr. Frith has favoured the Society with a free selection 

 from the above interesting collection. 



f Since the above description had gone to press, we have received Dr. Horsfield's 

 Catalogue of the Mammalia in the Hon. Company's museum, in which we find 

 ourselves forestalled as regards the specific name.
