 some horns with scalps attached of an Antelope sent to him from Somali- 

 Land by Capt. H. G. C. Swayne, R.E., which he referred to the lately de- 

 scribed Cervicapra Clarkii of Mr. Oldfield Thomas. — Mr. Sci at er also ex- 

 hibited two skins of the Ounce {Felis uncia) in reference to the specimen of 

 this Cat lately acquired by the Society, and made some remarks on the geo- 

 graphical range of the Ounce in Central Asia. — Mr. A. Smith Wood- 

 ward, F.Z.S., gave an account of some dermal plates of Homostcus from the 

 Old Red Sandstone of Caithness, lately sent to him by Mr. Donald Calder, 

 of Thurso, the examination of which had enabled him to advance our know- 

 ledge of some points in the structure of this remarkable form of extinct 

 fishes. — Mr. G. A. Boulenger, F.Z.S., gave a detailed description of 

 Simony's Lizard [Lacerto, Simonyij from the large specimen lately living in the 

 Society's Gardens, which had been brought from the rock of Zalmo, Cana- 

 ries, by Canon Tristram. — Mr. W. F. Kirby, F.E.S., gave an account 

 of a small collection of Dragon-flies made by Mr. E. E. Green in Ceylon. 

 The series contained examples of sixteen species, of which three appeared to 

 be new to science. — Mr. Oldfield Thomas read some notes on the speci- 

 mens of Antelopes procured by Mr. T. W. H. Clarke in Somali-Land, which 

 had been submitted to his examination by Messrs. Rowland Ward and Co. 

 The specimens were referred to eight species. One of these, already prelimi- 

 narily described as Cervicapra Clarkii, was now regarded as constituting a 

 new generic form allied to the Gazelles, and proposed to be called Ammo- 

 dorcas Clarkii. — P. L. Sci at er, Secretary.
