 it abounds. 



We dredged many Holothurise ; notably everywhere 

 below 200 or 300 fathoms the delicate little Echino- 

 cucumis typica, M. Sars ; and Psolus squamatus, 

 Koren, which does not seem however to be common,

 to which they were attached. Ilolothuria ecalcarea,

 which I figure as they are highly suggestive of the
