6 Melvill and Standen, Report on Arctic Mollusca. 



Some specimens are unusually large, and the species 

 is generally abundant. 



Mya truncata (L.). 



Hab. Near East glacier, Cape Flora, 4 — 30 fathoms, 

 also from floe in West Bay. From isolated beach of most 

 westerly rocks South of Mabel Island. Off Cape Gertrude, 

 12 fathoms. Giinther Sound, 10 fathoms, and from beach 

 at north end of Windy Gully. From walrus' stomachs, 

 Miers Channel (siphons only). 



Very abundant. All the examples obtained are small 

 sized, and the majority are excessively truncate, agreeing 

 exactl)' with var. uddcvalctisis Forbes. 



SCAPHOPODA. 



SipJi07wdentalium vitrciim (M. Sars.). 

 Trawled, 100 fathoms. 



PLACOPHORA. 



Chiton {Lepidopleunis) sp. 



Dredged, 140 fathoms. 



We have not been able to idcntif)' this, but it seems 

 near to C. alveolus (Sars.). The sculpture, however, in our 

 shell forms lines which do not occur in alveolus. It also 

 recalls C. fuligifiatus (Ad. and Roe.). 



Chiton {Boreochiton) uiarniorciis (P\ib.). 

 Hab. Off Cape Cortin, three miles, 



CJiiton {Lophyriis) albus (L.),
