height, 160 feet, gives an area of wall aud window saved by the circle of 21,7G0 

 superlicial feet. There would also be a saving in the distances to be walked over. 

 The whole museum would be lightning-proof aud also hre-proof, as no wood would 

 be used. The building to be faced with vermilion-coloured bricks with stone 

 dressings, the walls being strong and well bonded. A three-story museum of 3§ 

 acres costing £:350,000, one of b-^ acres would cost proportionably £705,000. The 

 expense of tlie twelve-story museum and its appendages, worked out in detail at 

 the prices current in April 1872, would be £^54,788, which includes £6471 for 

 kamptulicon lloor-cloths, seats, tables, and desks ; but it includes nothing for tlie 

 85 acres of land. This twelve-story inuseum could be built equally well on any 

 otiier site where the square of 400 feet had two of its adjoining sides bounded by 

 roads, if no other lofty buildings were erected too near it. [Messrs. Spon of

On a new lihlnoceros, luitJi Bemarhs on the Recent Species of this Genus and 

 their Distribution. By P. L. Sciater, M.A., Ph.D., F.B.S., Secretary 

 to the Zoological Society of London. 



On the 14th of February last the Zoological Society of London received in their 

 Gardens a female two-horned Ehinoceros, which had been captured near Chitta- 

 gong four years previously, and had been since kept in captivity at that station in 

 indfa. This animal had "been referred to Rhinoceros sumatrensis of Cuvier by the 

 author and by other writers who had spoken of it, that being the only species of 

 the Asiatic two-horned section of rhinoceroses hitherto recognized by naturalists. 



The recent acquisition of a female of tlie veritable E. sumatrensis from Malacca 

 had enabled the author to compare the two animals together, and had led hini to 

 the conclusion that the first-mentioned specimen belonged to a diti'erent_ species, 

 which he proposed to call Rhinoceros lasiotis, or Hairy-eared lUiinoceros, its most 

 obvious external peculiarity being the long hairs which fringe the ears. 



The existing species of Rhinoceros certainly known were considered by the 

 author to be six in number, viz. : —

The author exhibited specimens of bodies bearing the general external shape 

 and appearance of long thin tapering white willow wands from 4 to 6 feet in 

 leno-th, which he had received from Captain David Herd, of the Hudson's Bay 

 Company's service, with the information that they liad been brought by that 

 company's vessel from Barraud's Inlet, Washington Territory, North-west America. 

 The captain who brought them stated that they were the " backbones" of a gelatinous
