Mr. Martin called the attention of the meeting to a specimen of 

 the Dasypus hyhridus, in the collection presented to the Society by 

 C. Darwin, Esq. This animal, the tatou mulet of Azara, has been 

 characterised in all systematic works, as closely related to Dasypus 

 Peba, and as having large ears ; whereas the ears are much smaller 

 than in D. Peha, and but little larger than those of D. minutus. In 

 reference to this species, which he at first was unable satisfactorily 

 to identify, he observed that the vague and unsatisfactory account 

 given in systematic works would, he conceived, justify him in laying 

 before the meeting a more complete and definite description of the 

 animal than he had been able to meet with, the want of which he 

 had himself experienced, which he thus ventured to supply. The 

 description appears in No. xlix. of the Proceedings. 



Mr. James Reid exhibited to the Meeting, and characterized as 

 new, under the name of Obscurus, a dark- coloured monkey, from 

 the Society's collection, belonging to the genus Semnopithecus. 

 The locality of the particular specimen before the Meeting was 

 unknown. 



February 14, 1837. — A letter was read from C. R. Read, Esq., a 

 corresponding member, dated Singapore, September 2nd, 1836, an- 

 nouncing a present of 56 skins of birds, and the skin of an alligator 

 of large size, which have been received. 



At the request of the Chairman, Mr. Waterhouse brought under 

 the notice of the Meeting numerous species of the genus Mus, form- 

 ing part of the collection presented to this Society by Charles Dar- 

 win, Esq., a Corresponding Member. The specimens placed on the 

 table had been collected at various parts of the Southern Coast of 

 South America, viz. Coquimbo, Valparaiso, Port Desire, Maldonado, 

 Bahia Blanca, &c. 



Most of these numerous species were considered by Mr. Water- 

 house as hitherto undescribed, and drawings were exhibited by him 

 illustrative of the modifications observable in their dentition. 



The characters, dimensions, and particular habitats of the species 

 above referred to are given in No. I. of the Society's Proceedings, 

 under the following specific names ; viz. 



Mus tumidus, nasutus, obscurus, longipilis, olivaceus, micropus, 

 brachyotis, xanthorhinus, canescens, arenicola, bimaculatus, ele- 

 gans, gracilipes, flavescens, brevirostris, and Maurus.
