40 miles N.E. by E. from Scar- 

 borough. 

 Natica groenlandica, Beck. Not 

 uncommon, living with Scalaria 

 Trevelyana. As the animal has 

 not hitherto been described, 

 we subjoin the following note, 

 taken on board : — ' ' Body canary- 

 colour ; snout depressed in 

 front, not quite so wide as the 

 shell, slightly narrowing; ten- 

 tacles one eighth of an inch 

 long, pointed at the extremities 

 and flattened at the base, turned 

 back on the shell ; eyes none ; foot, 

 when fully expanded (which 

 is rarely), twice as long as the 

 shell, posterior portion rounded, 

 partly enveloping the shell ; 

 ovary reddish brown ; liver deep 

 olive." It is a very sluggish 

 animal ; and our first living 

 example tantalized us for three 

 hours before fully exposing it- 

 self, although kept in a saucer 

 with a little water ; while others 

 never showed themselves at all, 

 though kept for two or three 

 days. 



Natica catena, Da Costa. Ex- 

 ceedingly large. 

 * , var. Leckenbyi, Mar- 

 shall. Shell brown, without 

 any coloured markings. It has 

 much the appearance of N. sor- 

 dida, but is thinner and more 

 globose. Searles Wood's N. ca- 

 tena, from the Coralline Crag, 

 is similar to this. We obtained 

 them on the Dogger bank, in 

 10 fathoms.

The Starfish and Crustacea were everywhere most abundant, 

 but nothing calling for special remark. On one occasion,
