 (T.H.) Off the Deadman, &c. (C.W.P.) 



8 — S. Cecilii. — Biish, Quart. Journ. Micro. Soc. Zoophy., v,

Very variable ; Hincks has as well as the normal form, three 

 varieties, viz : a, cornuta ; /?, incrassata ; y, tuberculata. 



A very curious and delicate species ; it occurs on stones, shells, 

 and sea-weeds, from the very smallest to Laminaria saccharina, 

 and from tide marks to deep water. Abundant on the coast of 

 CornwaU. (C.W.P.) (T.H.) 



Genus, Mastigophora. — Hincks.

On the south coast this does not appear to be frequently met 

 with. Hincks got it off the Deadman in 60 fathoms — it occurred 

 to me off the same place in 1867, only one example. — SeeEeport 

 of Eoyal Institution of Cornwall for 1876, plate, fig. 3. (C.W.P.) 

 It is rather plentiful in the Out Haaf, Shetland, from 100 to 170 

 fathoms, on shells and stones. (C.W.P)
