Tlie Anoplotheriuin is an undescribed species, differing from those 

 of tiie Paris basin, and much larger, its size being between that of 

 the horse and of the Suraatran rhinoceros. It is founded on two 

 uppor jaws, with the near molars perfect. It is a true Anoplothe- 

 riuin, as distinguished from the subgenera of Xiphodun and Dicho- 

 bune. The discoverers have named it Anoplotherium Siva/ense. 'J'he 

 remains w^ere dug out of a bed of clay in the tertiary strata of the 

 Sewaiik hills, mixed up with bones of Sivatherium, Camelus Siva- 

 l nsis, Antelope, Crocodile, &c. The authors describe two species 

 of giraife. The first, which they designate Camelopardalis Sivalensis, 

 is founded on the third cervical vertebrae of an old animal, and they 

 infer it to have been one-third smaller than the existing species. The 

 bone is very perfect, and completely silicitied. It measures 8 inches, 

 -while the same vertebra of the existing species is 11 1 to 12 inches, 

 'ihe bone is more slender in its proportions than the existing one, 

 and exhibits a series of specific differences in addition to the size. 

 'J'he second species they name Camelopardalis ojpnis, provisionally, 

 from its close resemblance to the existing Cape Giraffe, in form and 

 size of teeth, &c. The species is founded on two fragments of the 

 upper jaw, with the back molars, and a fragment of lower jaw con- 

 taining the last molar. The dimensions agree to within the tenth 

 of an inch with those of a female head in the Aluseum of the College 

 of Surgeons. 7'he giraffe bones were found along with those of 

 Anoplotherium, Camel, Crocodilits biporcutvs, &.c., in a clay bed in the 

 Sewalik hills*.

A3IIM0LEAN SOCIETY. 

 Ojford, June 3. — Prof. Twiss read a paper in illustration of a 

 collection of speciruens of the Ova and Fry of the Salmon, presented 

 to the Ashmolean Museum by Mr. A. Young, the manager of the 

 Duke of Sutherland's fisheries on t!ie river Shin, in Sutherlandshire. 

 The collection consists of thirteen specimens of the ova, selected at 

 intervals varying from twenty to one hundred and thirty-three days 

 from the time of their being deposited, and ten specimens of the young 

 fry from the day on which they were hatched, the one hundred and 

 thirty-fifth after im])regnatiun, to the time when they assume the 

 silvery character of the smolt and descend to the sea, which in this 

 case was one year and nine days after exclusion from the egg. The 

 experiments of Mr. Young, which have now been carried on through 

 a period of three years with the greatest care, confirm the previous 

 observations of Mr. Shaw, in the Nith river in Dumfriesshire, in 

 their general bearings, with such slight variations as the different 

 characters of the respective rivers may account for. Mr. Young has 

 ascertained that the average period required for hatching the ova 

 of the salmon of the Shin river varies from one hundred to one hun- 



* The first announcement of the fossil remains of the Giraffe was made 

 by Capt. Cautlev in the Journal of the Asiatic Society of Bengal, vol. vii. 

 p. 65S (15th Ji.iy, IS.SS).
