It is to be regretted that no specimens of this very remarkable 

 species should have been preserved with the soft parts ; it being 

 probable that the fissure in the last valve and in the posterior part 

 of the margin is accompanied by some anatomical peculiarity in the 

 animal sufficient to establish its claim to generic distinction. 



Found under stones at low water. 



Chiton coarctatus. Ch. testd elongatd, postice coarctatd, sub- 

 tunicatd; valvis reniformibus , subdisjwictis , carinatis, asperis ; 

 carina dorsali lavi ; margine lavi. 



Long. 1 ; lat. *50 poll. 



Hab. ad insulam Bohol, Philippinarum. 



From the peculiar shape of the valves, and the comparative small- 

 ness of the portion which remains uncovered, the observer would be 

 led to look for the small tufts of hair found in the margins of some 

 similarly- shaped species. All the specimens, however, have the 

 margins perfectly smooth. 



Found under stones at low water. 



Aug. 10. — William Yarrell, Esq., Vice-President, in the Chair. 



A letter from the Earl of Derby was read. This letter is dated 

 August 7, 1841, and announces the arrival of a pair of the African 

 Musk Deer (Moschus aquaticus, Ogilby) ; one of them (a female) is 

 alive, and in good health, in his Lordship's menagerie. Having two 

 skeletons of this animal, his Lordship has directed one of them to be 

 forwarded as a present to the Society. 



A letter from Dr. Cox, dated Naples, March 28, 1841, was read; 

 it refers to some engravings of a deformed foetus which this gentleman 

 had sent for exhibition at one of the Society's scientific meetings. 



A letter from the Society's corresponding member Dr. Poey was 

 read. In this letter, which is dated Havannah, June 26, 1841, Dr. 

 Poey informs the Society that he has forwarded for the Menagerie a 

 living Raccoon, and he moreover makes some observations upon its 

 habits. 



A letter from Edward Blyth, Esq., was next read. This letter is 

 addressed to the Curator, and is written by Mr. Blyth on his passage 

 to India ; the writer relates some facts respecting various Mammals 

 which have been communicated to him by his fellow-travellers. 

 Lieut. Beagin, upon being shown some drawings of species of Gib- 

 bons, at once, in a figure of the Hylobates leucogenys, Ogilby, recog- 

 nised an animal which he had met with, and examined, in the Ma- 

 labar jungles. " Lieut. Beagin," observes Mr. Blyth, " has frequently 

 seen this species in the Malabar ghauts, generally in groups of eight 

 or ten, among which were brown individuals." " They appear to be 

 unknown on the Coromandel side, but extend eastward to the Neil- 

 gherries ; inhabiting upland jungles, chiefly at about 2000 feet above 

 the sea-level."
