presented by Mr. John Gunn ; a female Grysbok, presented by Mr. J. E. 

 Matcham, of Port Elizabeth, South Africa ; and a young male Panolia 

 Deer, from Southern China, presented by Mr. Julius Neumann. 



Mr. Sclater exhibited and made remarks on the head of a Barbary 

 Sheep, Oris tragelaphus, obtained by the late Capt. Dunning on the Nile 

 above Wady Halfeh, and the skin of a Humming-bird, Anthocephala 

 berlepschi, from Colombia, received from Mr. R. B. White. 



Prof. Howes exhibited and made remarks on the skull of a Rabbit 

 showing abnormal dentition. 



A letter was read from Dr. Hubrecht, showing that a supposed new 

 mammal from Sumatra, which he had described as Trichomanis hoevenii, 

 was probably nothing more than an Arctonyx. 



Mr. Sclater exhibited and made remarks on a specimen of Loder's 

 Gazelle, Gazella loderi, recently obtained in the western desert of Egypt. 



Mr. W. Saville Kent exhibited a drawing of a Nudibranch from Western 

 Australia, remarkable for its large size and brilliant colour. 



Mr. J. Graham Kerr read a paper on some points in the anatomy of 

 Nautilus pompilius. The morphological meaning of the arms in Cephalopods 

 was discussed briefly. It was pointed out that the only strong basis on 

 which the hypothesis of the pedal nature of these organs rested was that 

 derived from the consideration of their innervation by the "pedal" ganglion 

 or a derivative of it. The force of this evidence was completely dependent 

 upon the assumption that this ganglion was precisely homologous with the 

 pedal ganglia of Gasteropods; and this assumption appeared to be un- 

 justified, the evidence of comparative anatomy pointing to the independent 

 phylogenetic development of the several ganglia of Gasteropods, and of the 

 similarly named ganglia in the higher Cephalopods, from a condition of 

 continuous nerve-strands such as occurred in Chiton, Nautilus, and other 

 archaic forms. The author advocated the abandonment of the view that 

 the arms are pedal, and the resumption of what appeared the inherently 

 more probable view, that they are processes of the head-region. 



A communication was read from Messrs. F. E. Beddard and A. C. 

 Haddon, containing an account of a collection of Nudibranchiate Mollusca 

 recently made by the latter in Torres Straits. 



Mr. Boulenger read a paper on a large collection of fishes made by 

 Dr. C. Ternitz in the Rio Paraguay. 



A communication was read from the Babu Ram Bramha Sanval, giving 

 an account of the moulting of some Birds of Paradise in the Zoological 

 Gardens, Calcutta. 



A communication was read from Mr. 0. Thomas and Col. J. W. Yerbury* 

 giving a description of a collection of Mammals made by the latter at Aden 

 last winter. It was shown that thirty-six species of Mammals are now 

 known to occur in the Aden district.
