189S.] MR. BOULEXGER ON DISTIKA STOKESII. 851 



trotted or galloped away in a slow canter, so that I was able to 

 follow them for about twenty minutes by running, and I believe 

 I could have shot more of them had I not become quite exhausted. , 

 The following are the measurements of my four horns of 

 Hippotragus rufo-pallidus, the fifth being that of quite a young 

 animal : — 



November 29th, 1898. 

 W. T. BL.iNFOBD, Esq., r.E.S., V.P., in the Chair. 



Mr. P. Chalmers Mitchell, F.Z.S., exhibited and made remarks 

 on some etched studies of the young Orang-Outaugs recently 

 living in the Jardin des Plantes at Paris. 



Mr. G. A. Boulenger exhibited a dancing-stick from New Guinea, 

 marked " Native name Gooapey, from Dameracura, mouth of Fly 

 Eiver," to which two imperfect skulls of the rare Chelonian Caretto- 

 chelys insculpta Eamsay were attached as ornaments or charms. 

 This object had been acquired at Stevens's sale-room by the well- 

 known dealer Mr. Gerrard, and the skulls had been correctly 

 identified by his father, Mr. Edward Gerrard, lately of the Britisb 

 Museum, so distinguished for his great experience of osteological 

 specimens. 



The chief interest of the exhibit lay in the fact that since the 

 description of Garettochelys in 1886, from a single stuffed specimen 

 from the Ely E.iver, preserved in the Sydney Museum, nothing 

 had been heard of the occurrence of this extraordinary Turtle, the 

 affinities of which are still uncertain. The specimens exhibited 

 confirmed the account given by Baur in 1891, from photographs of 

 the imperfect skull extracted from the Sydney skin, and afforded 

 the further information that the pterygoids are not turned up in 

 front, being in fact absolutely similar to those of the Trionychidce, 

 and that the premaxillary is single, a feature otherwise restricted, 

 among Cheloniaus, to Chelys and the Trionychidce. 



Mr. Boulenger also exhibited a large female specimen of the 

 Sea-snake Distira stohesii Gray, measuring 1| metres. It had 

 been caught by Mr. E. W. Townsend in August last, floating on the 

 surface in Kurrachee harbour, entirely covered with a thick growth 

 of green weeds, which bad been kindly determined by Mr. Vernon H.
