which both the second incisors were wanting, and as von Nathusius, 

 in his lengthy experience of the Leporines, had recorded ' but two 

 similar cases, the variation would appear to be very exceptional. 

 In the specimen exhibited the single pair o£ incisors in both upper 

 and lower jaw were longer and more curved than is usual where 

 the smaller upper incisors are present. This was most marked in 

 the lower jaw, the cutting-edges of the incisors, instead of termi- 

 nating posteriorly on a level with the upper surface of the sym- 

 physial end of the mandible, standing 3 millim. above it. In 

 this greater elongation of the incisors the specimen approximated 

 the more closely towards the simplicidentate type. 



Nathusius had remarked of one of the two examples which fell 

 into his hands that not only were there no traces of the teeth in 

 question, but that there were no indications of their having been 

 developed and subsequently lost. In the specimen which Prof. 

 Howes exhibited the premaxillse bore a couple of excessively 

 minute perforations, which might possibly be the reduced vestiges 

 of the alveoli of the missing teeth. That of the left side, however, 

 led off into an outwardly directed groove, and from the characters 

 of these passages, in consideration of the recent cf\ref ul investigation 

 of Aschenbrandt ", he was disposed to regard them as those of transit 

 of palatal branches of the naso-palatine nerve. 



The cheek-teeth of the specimen showed no features that were 

 exceptional. 



A letter was read, addressed to the Secretary by Dr. A. A. W. 

 Hubrecht, F.M.Z.S., calling attention to the account of a supposed 

 new Mammal from Sumatra by him, published in the ' Notes from 

 the Leyden Museum ' (vol. xiii. p. 241), under the behef that it 

 would turn out to be an unknown species of Edentate, and which he 

 had proposed to call Trichomanis Jioevenii. further inquiries and 

 information received from Mr. Pruys Van der Hoeven (after 

 whom the supposed new animal had been named) had convinced 

 Dr. Hubrecht that it was an Arctonyx {A. coUaris), and that no 

 further hopes could be entertained of the existence of an unknown 

 Edentate in the forests of Sumatra. 



In reference to his remarks made at the last meeting (see above, 

 p. 400) on the existence of a second Gazelle in Egypt, besides 

 Gazella clorcas, Mr. Sclater exhibited the skin and skuU of the 

 male Gazelle of this second species which he had seen alive at 

 Cairo. These had been kindly sent to him by Mr. Jennings Bramley. 

 Mr. Sclater had ascertained, by comparison with one of the typical 

 specimens in the British Museum, that they were referable to 

 Mr. Thomas's lately described species Gazella loderi (P. Z. S. 1894, 

 p. 470, pi, xxxii.), the extension of which into Egypt was a novel 

 fact of great interest.
