*5 



Sertularia operculata L. Silecroft, a piece about three inches 

 long. 



Sertularia fi lieu la E.&S. Silloth. 



Sertularia abietina L. Hodbarrow, a good piece loose, and 

 at Silecroft and Bootle. This species often — and others 

 also — heavily covered by the shell Spirorbis serpnloides. 



Sertularia cupressina L. Silloth, with capsules, a piece 

 about 7^/2 inches long. 



Sertularia argentea E.&S. Silecroft, on shell of ? Astarte, 

 and on other hydroids, and one good piece alone ; Silloth. 



Hydrallmania falcata L. Hodbarrow, on mussel shells ; 

 Silecroft, on ? Astarte, and common ; Bootle, loose pieces ; 

 Silloth, common. 



Antennularia antennina L. Silecroft, some broken pieces, 

 one covered by a sponge — first-named at foot of this. 



Corallina officinalis L. Common from mussel shells at Hod- 

 barrow and Silloth shore. 



SPONGES. 



Spongelia fragilis Schmidt. Silecroft, another specimen, and 



one named above. 

 Chalina oculata Bk. Silecroft, several specimens. 



I did not find the Spiny Cockle {Cardium aculeatum ?) so 

 plentifully at Silecroft as when last there in 1887. Amongst the 

 valves of this a small battered specimen of an Echinus was 

 found, still bearing a few spines much bleached. 



I shall be glad to receive specimens from any Cumberland 

 coast station not in this list, and will name and return them if 

 their state will allow, on the condition that their names are 

 afterwards printed in this journal. 







NOTE POLYZOA AND MARINE ALGJE. 

 Polyzoa and Marine Algze from Scarborough Neighbourhood.— 



Mr. A. J. Parke, of the Malton Naturalists' Society, has lent me a small 

 collection of Seaweeds, g-athered in the neighbourhood of Scarborough. 

 As most of them are catalogued in Mr. Massee's list in 'The Naturalist,' 

 and as some possibly require confirmation of names, only those bearing- 

 Polyzoa are given below, with one exception. 



Scrnpocellaria scrnposa L. On ? Rytiphloea fruticulosa Harv. 



Membranipora pilosa L. On ? Splice rococcus eoronopifolius Ag. 



Membranipora dentata. On ? Rytiphlcea fruticidosa Harv., Maugeria 

 sanguined S.O.Gray, Callophyllis laciniata Kiitz., and Schizymcu ia 

 edulis Stackh. 



Crista ebur?iea L. On ? Rytiphla'a fruticulosa Harv. 



What appears to be a Lepralia, but not in a condition to name, possibly 

 tooyoung, on Callophyllis laciniata Kiitz. and Gigartina mamtllosaAg. 



Sertularia operculata L. On Ahnfeltia plicata Fries. 

 One omission in Mr. Massee's list is supplied by Mr. Parke's Corallina 

 squamata Parkinson. — S. L. Petty, Ulverston, 22nd November 1900.
