Dr. P. L. ScLATER, F.R.S., made some remarks on the specimens 

 of the Okapi lately inspected by him in the Congo Free State 

 Museum, at Tervueren, near Brussels. 



Mr. W. B. Tegetmeier, F.Z.S., exhibited a specimen of the 

 Asiatic King Crab which had been discovered in a living condition 

 off the Isle of Wight. 



Mr. Oldfield Thomas, F.E..S., read a paper on the Mammals 

 obtained in the island of Fernando Po by Mr. E. Seimund during 

 an expedition supported by the Society's President (the Duke of 

 Bedford), Mrs. Percy Sladen, and the Hon. Walter Rothschild. 

 Twenty-four species were enumerated, and the two following new 

 subspecies were described : — 



Galago demidoffi poensis, subsp. n. 



Similar to true G. demidoffi, but the under surface much paler, 

 and the inner faces of the limbs pure white. Size as in the typical 

 form, 



ffab. Bantabiri, Fernando Po, alt. 1800 m. 



Type. B.M. no. 4.7. 1.8. 



Anomalurus fraseri nigrensis, subsp. n. 



Similar to true A . fraseri, but size smaller and colour paler. 



Length of hind foot 57 mm. Skull : tip of nasals to back of 

 parietais 53 mm. ; length of upper tooth series 11-9 mm. 



Hab. Abutschi, Lower Niger. 



Type. B.M. no. 2.11.10.5. 



A special genus, Sylvisorex, with type *S'. morio, Gray, was formed 

 to include the Shrews hitherto put with 31. varius in Myosorex, and 

 another, Mimetilhis, for the Bat described as Vesperugo (Vesperus) 

 moloneyi Thos. 



A list was appended of the Mammals, 36 in number, now 

 known to inhabit the island. 



Mr. Oldfield Thomas also read a paper, entitled " On Hylo- 

 chcerus, the Forest-Pig of Central Africa," and exhibited the 

 skulls and portions of skin of this animal obtained by Mr. R. 

 Meinertzhagen in the Nandi Forest, British East Africa. 



This Pig had been heard of by the late Sir H. Stanley, Sir H. H. 

 Johnston, Mr. F. J. Jackson, and other naturalists, but Mr. Mein- 

 ertzhagen was the first to obtain specimens of it, and these he had 

 presented to the National Museum. 



Hylochoerus m&mertzhageni, as it was proposed to be called, 

 proved to be a remarkably interesting type, annectant in many 

 respects between the ordinary Pigs and the Wart-Hog {Phaco- 

 choerus), to which latter on the whole it was most nearly allied. It 

 agreed with that genus in the number of its incisors, the presence 

 of large basisphenoid pits, the great thickness of the upper 

 canines (though not their length), and in the direction and shape 

 of the lower ones. Its molars were not hypsodont, but were of a 

 type very different to that found in &'us, and one fi'om which the 

 peculiar hypsodont molars of Phacochoerus might conceivably have 

 been evolved. 



The genei'al shape of the skull was more nonnal than in Phaco- 

 choerus, while in the breadth of the crown there was a peculiar
