66 THE VOYAGE OF H.M.S. CHALLENGER. * 



1879, Mr Edgar Smith mentions this shell as having been obtained with the aid of a grapple 

 out of a cleft in the rocks at 4 fathoms depth, at Observatory Bay, Kerguelen Island. I 

 have seen the specimen in the British Museum, and it certainly belongs to the species so 

 named by Lamarck, but it remains still to be determined whether it is specifically distinct 

 from Waldheimia venosa, Solander. Mr E. Smith says : " Reeve questions the correctness 

 of the habitat attributed to this species by Gray, but considering how many species of 

 animals found at Kerguelen Island are also indigenous to the Patagonian seas, there can 

 be Little doubt that Gray was correct in this instance." 



Waldheimia septigera, Lovdn. 



In his work MoUusca Regionis Arcticse Norvegise, 1878, Dr G. 0. Sars describes this 

 sheU as in all probability a true Arctic species. Professor Herman Friele, however, 

 informs me by letter that he is unable to agree with Sars in regarding it as a true Arctic 

 form, or its asserted occurrence in the cold area. He further states that Waldheimia 

 septigera is not found, so far as he is aware, living there ; some dead valves only were 

 dredged by Sars outside the steep Banks of Aalesund in 1872. During the Norwegian 

 North Atlantic Expedition, it was not found either in the cold area or north of Finmark ; 

 and neither he nor Sars dredged it above lat. 65°. Lovdn states that he has found it 

 in Finmark. It has never hitherto been obtained at Spitzbergen. In the Arctic seas it 

 is replaced by Terehratella spitzbergenemis, Dav. 



Magasella cumingi, Dav. 



Mr John Brazier, of Sydney, Australia, informs me by letter that this species is so 

 exceedingly abundant at Pigs Rocks, Port Jackson, that in one haul he obtained about 

 one hundred dead specimens at a depth of 3 to 4 fathoms ; bottom, sand and mud. At 

 South Reef, Port Jackson Heads, in 10 fathoms, bottom of broken shells, stones, and 

 coarse white sand, he obtained twelve living specimens, of which he sent me examples ; 

 they are of a light salmon colour. Although quoted by Cuming from New Zealand, Mr 

 F. W. Hutton of the Otago Museum, Dunedin, assures me he has never seen a New 

 Zealand specimen. 



Mr Brazier has also dredged Megerlia pulcheUa ofi" Bottle and Glass Rocks, Port 

 Jackson, rocky bottom, 5 fathoms, attached to a large Sp>ondylus. In the year 1868 he 

 obtained a few specimens near the rocks at Camp Cove or Green Point, Port Jackson, 

 in 7 fathoms, bottom of bi'oken shells and sand ; and in 1869 he found a specimen which 

 was washed on shore at Cabbage Tree Bay, outside Sydney Heads, and which was well 

 marked with red. Mr Brazier dredged Megerlia sanguinea at Sandal Bay on the north- 

 west side of the island of Lifou, Loyalty Islands, in 1873, the beach being strewn with it ; 

 he also found a small specimen of this shell attached to Pecten palliwn, Lam., at Wantoro,
