On the tube of an Annelid from deep water. 



I got this addition to the British list first in August, 1844, 

 from deep water off Groran Haven, and marked it in my diary 

 as '■'■ new, and of a dark-red colour." In 1877, I again turned 

 it up in my Cornish gatherings, on finding another, and then 

 marked it as Memhranifora Ro%ieri, of Busk's Crag Polyzoa. — To 

 Mr. Hineks is due the credit of truly defining it, and for the 

 new name. 



It is exce.edingly rare. (CW-P.) 



Genus, Cribrillina. — Gray. 



1 — Cribrillina Eadiata. — Moll. 



Eschara Eadiata. — Moll., Secrinde, 63, plate iv, fig. 17.

 fig. 4. 



Cribillina Eadiata. — Hinchs, Brit. M. Poly., p. 185, fol. xxv, 

 figs. 1, 9. 



This very pretty species is rather variable ; Hineks finds three 

 varieties, and at times a little puzzling. Par from rare, I have 

 got it in several localities in Cornwall, Sufi^olk, Aberdeenshire, 

 Caithness, and Shetland. As well, I have found it as a Boulder 

 Clay Fossil in Caithness. (C.W.P. 



The range in depth is from a little beyond low water to 170 

 fathoms. (C.W.P.)

 Brit. M. Poly., 190, plate xxvi, figs. 1 — 4, and plate xxiv, fig. 3. 



A very variable species, always beautiful, and widely dis- 

 tributed. It occurs between tide marks, on Algae, stones, &c., 

 in no great depth of water. (C.W.P.)
