KHOiL TIII-: COAST OK BHITISH COLUMBIA. 119 



HiNNlTES (HOANTEUS, Gnii/. Entrance to Maluspina Inlet, associated with the two pre- 

 ceding species, one rather small and dead specimen. Low water at Fort Rupert, 

 on the north-east .-oast of Vancouver Island, one adult living shell, and a similar 

 one from the entrance to Quatsiuo Sound, also at low water. 



I'KCTEN AI-ASKKNSIS, Dnll. Quatsiuo Sound at station No. 20, one small but living 

 specimen. This species, which has hitherto been recorded as occurring only at 

 " North Harbor, Unga Island," and " Port Etches, Chugach Gulf," is new to the 

 Vancouver region. 



I'r.cTKX ii VST ATI'S, Soiverby. (=P. Jwrimnt. Grid.) Strait of Georgia at station No. 6, one 

 living, adult shell, with the exterior of both valves nearly covered by an encrusting 

 sponge. Goletas Channel, one small but living shell. Quatsino Sound at station 

 No. 1!'. live adult, living and brightly coloured specimens of the typical form of 

 the species, in which the principal ribs are few, distant, and ornamented with erect 

 vaulted scales. 



PECTEN ITASTATUS, var. HINDSII, Carpenter. Strait of Georgia at station No. 5, two rather 

 small, living shells and a few fragments. Discovery Passage at station No. 7, two 

 small, living shells and three single valves. Johnstone Strait at station No. 10, 

 four medium sized, living specimens (one passing distinctly into the var. rubidus) 

 and a few very small ones. Queen Charlotte Sound at station No. 14, one living 

 specimen ; at station No. 17, three small living shells ; and at station No. 18, one 

 small, living shell. Quatsino Sound at stations No. 19 and 20, a few living speci- 

 mens of various sizes. 



LIMATULA SL'iui'RicuLATA,' Monlugu. Johnstone Strait at station No. 10, and Queen 

 Charlotte Sound at station No. 14, a single living specimen from each of these 

 localities. Not included in the Vancouver fauna in Dr. Carpenter's " Guide to the 

 Diagnosis of the Vancouver and Californian Shells," on pages 122-150 of his last 

 report on " The Mollusks of Western North America," published in 1872 by the 

 Smithsonian Institution. 



YOLDIA LANCEOLATA, /. Smverby. Quatsino Sound at station No. 20, a few living specimens. 



/ YOLDIA (PORTLANDIA) THRACI^EFORMIS, Storer. From the same station as the last, two 

 small but living specimens. This species also is new to the Vancouver district. 



/ LEDA FOSSA ? Baird. Discovery Passage at station No. 7, one single and worn valve. 

 ^LEDA MINTJTA, O. Fabricius. Quatsino Sound at station No. 19, two living specimens. 



LEDA ACUTA, Conrad. (=L. cuneata, Sowerby.) Same locality and station as the preceding ; 

 ten perfect specimens (most of which were living) and three single valves. 



A single valve of a Leda from Houston Stewart Channel, Queen Charlotte 

 Islands, which was referred by the writer to the Leda ccclala of Hinds (on p. 200 B 

 of the Report of Progress of the Geological Survey for 1878-79) is almost certainly 

 referable to L. acuta, Conrad, of which, according to Dall, L. cuneata, Sowerby, is a 

 synonym. On the other hand, in the sixth volume of the " American Journal of 

 Conchology," (p. 55) Dr. J. G. Cooper suggests that Leda cuneata may be only a 

 variety of L. calata.
