Nouvelle Hollande par MM. Quoy et Gaymard." It has been 

 much distorted in stuffing, but indicates a large brown or brownish- 

 grey animal, like the figure in the 'Voyage de 1' Astrolabe,' plate 12. 

 The description quoted above, on the other hand, indicates an animal 

 rather grey than brown, like the skin of the female which I have 

 received from Mr. Ramsay. The adult male, however, at the 

 Fisheries Exhibition, and the second specimen there, which I take 

 to be a young male, agree fairly well with the type specimen at 

 Paris and with the figure. I would suggest that the description may 

 have been taken from a female skin, which MM. Quoy and Gai- 

 mard believed to belong to a male, while the figure (which appears 

 to have been drawn on the spot, for the authors say that the atti- 

 tude is that in which the animal lay after death) was really of a 

 male. We know, however, so little about the external appearance 

 of Otarias, and they look so different according as they are young or 

 old, wet or dry, that we must wait for further material before these 

 points can be cleared up. For the same reason I would for the 

 present return to the original generic name, and refer these specimens 

 to Otaria cinerea, Pe'ron. 



In 1874 Dr. Gray received a somewhat imperfect skull of an 

 Otaria from Dr. Hector, which he referred to this species by com- 

 paring it with Quoy and Gaimard's figure, though, as was his wont, 

 he made a new genus for it, and called it Euotaria cinerea'*. This 

 skull is now in the British Museum, along with others received subse- 

 quently from Dr. Hector. These skulls are undoubtedly of the same 

 species as that to which, as mentioned above, Dr. Hector has given the 

 name Arctocephalus cinereus, or "Fur Seal of Australia." Whether 

 this Fur Seal be identical with the small Fur Seal which I have called 

 Otaria forsteri, as mentioned above, is a question which cannot be 

 settled until we obtain a larger series of specimens of different ages 

 and sexes ; but I feel certain that it is different from the Otaria now 

 before us. The skulls are all broader in proportion to their length ; 

 and the molars have not the three prominent cusps which appear to 

 be characteristic of this species.

Mr. H. O. Forbes has lately described (Proceedings of this 

 Society, 1883, p. 586), under the provisional name of Thomisus 

 decipiens, the habits of a Spider which he met with in Sumatra aud 

 Java. The Spider itself is remarkable from its exact resemblance to

 Museum' (8vo, London, 1874), p. 34.
