The fine Axinus Sarsii was much more abundant in 

 these dredgings than A.flexuosus, and attains much greater 

 size, especially at Stations 7 and 24. I am unable to satisfy 

 myself that it is more than a variety oi A.flexuostis, but it is not 

 a variety which results either from softness of ground or depth 

 of water, as suggested by Jeffreys on Malms' authority (Brit. 

 Conchol., ii., p. 251), for my finest specimens are from very 

 shallow water and the softest possible ground. 



57. Axinus Croulinensis, Jeffreys.

This very small but strongly characterized species is at 

 once known from the young of its congeners by its long and 

 conspicuous muscular impressions, which appear shining as 

 opaque, white lines through the shell. Muddy bottom, 100- 

 400 fathoms. 



65. Cardium minimum, Phil A shell never absent from the 

 greater depths, of which it is markedly characteristic.
