Mr. Sclater exhibited and made remarks on an original watercolour draw- 

 ing by Sir Harry Johnston, K.C.B., of the remarkable new Mammal from 

 the Semliki Forest in Uganda, which had been described (from fragments of 

 skin only) under the name Equus Johnsioni^ and announced that the complete 

 skin and two skulls from which it had been prepared were now on their 

 way home. There could be no doubt that the animal was not an Equus. 

 and could not be placed satisfactorily in any known genus of recent Mam- 

 mals. — Dr. W. G. Ride wood, F.Z.S., exhibited and made remarks on a 

 series of microscopic preparations of the hairs of Antelopes, Giraffe, Zebra, 

 and the so-called Equus Johnstoni , pointing out that the hairs of the last- 

 named animal were similar to those of the Giraffe as well as those of the 

 Zebra, but differed from those of the Antelopes. — Mr. R. I. Po cock, 

 F.Z.S., communicated a paper by Mr. G. W. Peckham, "on the Spiders of 

 the Family Attidae found in Jamaica, West-Indies". It contained descri- 

 ptions of thirteen new species, of which one was made the type of a new 

 genus — Nilahanfha. — Dr. David Sharp, F.R.S., F.R.S. , communicated a 

 paper by Mr. Peter Cameron, containing an account of the Hymenoptera 

 collected during the "Skeat Expedition" to the Malay Peninsula. Fifty-four 

 species were enumerated in the paper, of which thirtyone were described as 

 new. — Dr. David Sharp also communicated a paper by Mons. Eugène 

 Simon on the Arachnida collected during the "Skeat Expedition." It con- 

 sisted of a list of the 131 species represented in the collection and descri- 

 ptions of 48 new species and 4 new subspecies. — P. L. Sclater, Secretary. 

 May 21st, 1901. — Mr. R. I. Pocock, F.Z.S. exhibited, on behalf of 

 the Director of the British Museum (Natural History) , a hind foot of the 

 Canadian Beaver, showing the duplication of the claw on the second toe. — 

 Mr. Oldfield Thomas read a paper on the more notable mammals lately ob- 

 tained by Sir Harry Johnston in the Uganda Piotectorate. The following 

 species were described as new: — Colohus Btnveiizorii ^ allied to C. palliatus, 

 but with longer hair and less white on the tail-tip ; Genetta vicloriae^ a Genet 

 nearly as large as a Civet, strongly banded, and without a dorsal crest; Pro- 

 cavia marmota^ like P. chrsalis, but much smaller; and Cephalophus Johnstoni^ 

 like C. Weynsi, but darker throughout. — A communication was read from 

 Mr. R. C. Punnett containing an account of the Nemerteans collected by 

 Prof. D'Arcy W. Thompson and others in Behring Straits, Davis Strait, 

 and North Greenland. Of the seven species enumerated in the paper two 

 had been previously named, whilst the remaining five- were nevv to science 

 and were described as Amphiporits arcticxs, A. paulinus, A. Thompsoni , Dre- 

 panophorus borealis, and Cenhraiuhts greenlandicus. — A communication was 

 read from Dr. W. B. Ben ham, F.Z.S. , containing an account of the viscera 

 of a Whale of the genus Cogia. He pointed out that in this Whale there is 

 but a single blowhole asymmetrically placed like that of Physeter ^ but cres- 

 centic in outline, with the concavity directed backwards. The alimentary 

 canal contained a dark-coloured substance, which the author considered to 

 be the "ink" from the cuttle-fishes upon which this Whale undoubtedly feeds, 

 as was evidenced by the beaks of these molluscs in the stomach. The stomach 

 was constructed upon the plan ofthat of the large Sperm- Whale (P/^yse/e?-), and 

 the author agreed with others in regarding the first division of it as a paunch 

 belonging really to the oesophagus, and comparable with that of the Rumi- 

 nants. — Mr. G. A. Boulenger, F.RS., described two new species of
