196 MF. R. I. POCOCK ON BURCHELL's ZEBRA. [Nov. 3, 



near- the base of the outgiowth, the shell presents an appearance 

 not unlike that of a snail-shell which has undergone repair, so 

 that this variation would seem to lend support to the theory that 

 such duplicate parts may arise from injury. This, however, 

 cannot have been the case. The animal would scarcely have 

 survived such an injury. The specimen was the property of 

 Mr. G. A. Doubleday, who has kindly presented it to the British 

 Museum." 



Mr. R. I. Pocock, F.Z.S., exhibited two photographs (text- 

 fig. 22, opposite) of a specimen of Burchell's Zebra which has been 

 preserved for many years in the City Musevim at Bristol. The 

 photographs were kindly taken by Mr. William Moline, and every 

 facility for doing so was afforded by the Secretary and Curator, 

 Mr. Bolton, F.R.S.E., with the sanction of the Committee of the 

 Bristol Museum. 



The specimen is a small male, probably not quite full-grown, 

 standing 44 inches at the withers. Unfortunately, its locality is 

 unknown and nothing of its history can now be traced. Its im- 

 portance and interest, however, lie in the fact that it belongs to the 

 typical race of Burchell's Zebra, or, as it should be more properly 

 called, Burchell's Quagga [Equus quagga hurchelli), which is either 

 extinct as a wild animal or, at all events, verging on extinction. 

 Hence it is desirable that the characters of every specimen now 

 living in captivity or exhibited in museums should be permanently 

 recorded by photography. 



A marked difference between the Bristol example and the 

 typical example described and figured by Gray, but now unfor- 

 tunately lost, is to be found in the distinctness and distribution of 

 the paler, narrower, intermediate stripes. In the specimen sent 

 to the British Museum by Burchell these stripes, as attested by 

 the figure, were long, sharply defined, and extended without a 

 break from the hind-quarters to the head. In the Bristol speci- 

 men, on the contrary, they are short and pass from the hind- 

 quarters only halfway along to the shoulder. Owing to scarcity 

 of material of this rare animal, the exact systematic value of this 

 difference is unknown. 



Mr. Pocock also exhibited an example of a species of Notiphilides, 

 one of the Geophilomorphous Centipedes. The specimen came 

 from Venezuela, and is remarkable for its great length. It 

 measures 283 mm. (or nearly 11 inches) long and 9 mm. (or 

 about \ of an inch) broad — that is to say, it is, roughly speaking, 

 twice as long as the average-sized specimens of the largest species 

 hitherto recorded. 



Mr. Oldfield Thomas, F.R.S., exhibited specimens of three new 

 Mammals, two of them representing new genera, which had been 

 collected by Mr. A. S. Meek in British New Guinea. Besides 

 these new forms Mr. Meek had obtained in the same region 

 examples of several very rare species, such as Dorcopsis macleayi,
