 Common, and in all the usual protean forms, both attached and 

 free and labyrinthic. The specimens are well developed and 

 quite typical, but do not, of course, attain a very large size 

 compared with those obtained from warm seas. Minute 

 specimens, exhibiting the regularly spiral arrangement of the 

 «arly chambers, are of frequent occurrence in the fine floatings. 

 (Plate 11, Figs. 1, 2, 3, and Plate 14, Fig. 2.) 



The species has been previously recorded from the Cornish 

 coast, 60 fathoms, and Mounts Bay, Cornwall (F. W. Millett) ; 

 also from the Southport coast (Chaster), and Kilchattan Bay, 

 Bute, 25 fathoms (Robertson). It does not appear to have been 

 recorded from Ireland.
