King George's Sound (Quoy fy Gaimard); Houtman's Abrolhos (Gould). Pelage brown in males, with a distinct yellow space on the back of the neck ; in females grey, becoming a dirty white on the neck and head; red under the body. The line of demarkation between the red and grey is said to be very distinctly marked. No under-fur. Nails on all five digits of " pes." Snout short; nostrils on upper surface. Teeth 36, sometimes 34 ; first four upper and lower molars with anterior cusp; last two upper and last lower tricuspid. Skull rounded behind orbits. Opening of palate wide, V-shaped. 4. OTARIA HOOKERI. 1844. Arctocephalus hookeri, Gray, Zool. Erebus and Terror, Mammalia, p. 4. 1871. Phocarctos hookeri, Gray, Suppl. to Cat. of Seals and Whales, p. 15. 1873. Otaria hookeri, J. W . Clark, P. Z. S. p. 750. Hab. Auckland Island (J. W. Clark) ; Campbell Island (French Expedition, 1875); coast of New Zealand, subfossil (Dr. Hector). I suggest this rearrangement of the Australian Otariidce with much diffidence, as the quantity of material at present available is quite insufficient for any thing like certainty respecting them. I am especially doubtful about the identity or difference of O. forsteri and O. cinerea. Allen (I. c. p. 40) considers that " Peron, under the name Otaria cinerea, undoubtedly referred to Zalophus lobatus of recent writers." Still the additional cusp to the molar teeth in the latter would seem to preclude the possibility of their being the same. 9. On the Generic Peculiarities of the distinctively Madeiran Achatince of Lowe. By the Rev. R. B O O G W A T S O N, F.R.S.E., F.G.S. Communicated by J. G W Y N JEFFREYS, Esq., LL.D. [Received October 27, 1875.] I have to propose a new genus for certain species of Madeiran Mollusca hitherto classed as Achatince. The name Lovea is a tribute to the labours of Mr. Lowe in connexion with these species, as, indeed, with the whole Natural History of Madeira. The distinctive characters of the genus in which it differs from Achatina are:- The mantle extends beyond the edge of the aperture all round. It is thinly spread over the outside of the shell, and extends like tongue backwards behind the posterior corner of the aperture. The tail carries a mucous gland and is abruptly truncate. |
