598 Zoological Society, 



Mus Abbottii, from Trebizond. 



This species is less than the harvest mouse (Mus messorius), and 

 of a deeper colour than the Mus musculus, in which respects it agrees 

 with Mus Alleni ; from this, however, it may be distinguished by the 

 tail being longer in proportion, the ears larger, and the tarsi more 

 slender. It was presented to the Zoological Society ,by Keith E. 

 Abbott, Esq., Corr. Mem., after whom it has been named. 



Mr. Gould then continued the exhibition of Mr. Darwin's Birds, 

 a series of which were upon the table. One only among them was 

 considered new, a species belonging to the genus Pyrgita from the 

 island of St. lago. Mr. Gould characterized it under the name of 

 Pyrgita lagoensis, from St. lago. This is in every respect a typical 

 Pyrgita, and rather smaller than the common species, P. domestica. 



Mr. Gould then called the attention of the Members to some spe- 

 cimens of M. alba and M. Yarrellii, which presented in a very de- 

 cided manner the distinctions referred to by him at the last Meeting, 

 He afterwards characterized a new species of that genus under the 

 name of Motacilla leucopsis, from India. 



August 8th, 1837.— Mr. Gould then characterised the following 

 birds from the Society's collection as new species : 



Corvus nobilis, from Mexico. This beautiful species is a true 

 raven, and may be distinguished from the European, and from that 

 inhabiting the United States of America, by the more metallic lustre 

 of its plumage, by its more lengthened and slender bill, the greater 

 length of its primaries, and the more cuneate form of its tail. 



Ortyx guttata, from the Bay of Honduras ; Thamnophilus fuligi- 

 nosus, from Demerara ; Dendrocitta rufigaster from India. 



Mr. Ogilby exhibited skinspf two species of his new genus Kemas*, 

 and directed the attention of the Society to their generic and specific 

 characters. Mr. Ogilby observed, that the genus in question occu- 

 pied an intermediate station between the goats and the Oryges, 

 agreeing with the former in its mountain habitat and general con- 

 formation, and with the latter in the presence of a small naked muzzle 

 and four teats in the females. Of the two species exhibited, one 

 was a fine male specimen of the IJiaral, presented by James Far- 

 rail, Esq., and the other a new species from the Neilgherry Hills, 

 known to Madras and Bombay sportsmen by the name of the Jungle 

 Sheep, and which Mr. Ogilby had long looked for. In form and 

 habit of body, as well as in the character of the horns, this animal 

 is intermediate to the Iharal and Ghoral ; the specific name of Kemas 

 Hylocrius was proposed for it in allusion to its local appellation. 

 The body is covered with uniform short hair, obscurely annulated 

 like that of most species of deer, and more nearly resembling the 

 coat of the Ghoral than that of either the Iharal or Chamois, the 

 other species of which the genus is at present composed. The horns 

 are uniformly bent back, surrounded by numerous small rings, 

 rather flattened on the sides, with a small longitudinal ridge on the 

 inner anterior edge : the ears are of moderate length, and the tail
