Mr. Ball states that the habits of the Irish Seal differ so much from 

 those ascribed to it in the Baltic, that he thinks it may, on compa- 

 rison, prove to be a distinct species. The colour of the Irish animal 

 varies so much, from sex, age, season, &c., that it cannot be regarded 

 of value as a specific character ; the brain is very small compared 

 with that of Phoca, and its intellectual power bears the same pro- 

 portion. It may always be distinguished from other Seals by its 

 straight profile, fierce aspect, and greater proportionate length. — Proc. 

 Royal Irish Acad. Dec. 1836, p. 18. 



The skull figured by Mr. Clift in Home's paper in the PhU. Trans. 

 1822, t. 27, with other bones of the body, is in the Museum of the 

 lloyal College of Surgeons (see Owen, Cat. Ostcol. Coll. Mus. Coll. 

 Surg. p. 643. no. 3943, from a specimen given by Mr. Oxendon to 

 Mr. Hunter). It was shot in the Orkneys. 



The " Grey-bearded Seal from Orkney " (Home, Phil. Trans. 1822, 

 t. 28, skull, cop. Ball, f. 31), Mr. Ball regards as the skull of Phoca 

 vittdlna with some teeth of P. Grcenlandica inserted in the upper 

 jaw. — Ball, op.cit. Dec. 1836, p. 18.
