VINE: NOTES ON POLYZOA FOUND AT CLEETHORPES, 9 
logue, No. 1,047), by tracing back for themselves the long list 
of synonyms and references given in the catalogue. The best 
examples of the species that I have from Cleethorpes were only 
obtained in the early part of August this year. The finest 
colonial growths were on the inside of Soden ensis—the other 
on Buccinum undatum. 
12. Membranipora membranacea L. 
B.M.P., p. 146, pl. xviii., figs. 5-6. 
Common on Laminaria digitata. 
13- Membranipora sp. 
A small fragment, the zocecia of which are hexagonal in 
outline, but I could not place it wpraieaee under Busk’s name. 
See Hincks’ B.M.P., p. 143. 
14. Membranipora pilosa L. 
= Eleva pilosa Busk, Chal. ae p. 78. 
B.M. P. ,-p.: 437; pl. xxiii., figs. 1 
Common everywhere on Se ‘Bauch coast. The best 
examples obtained at Cleethorpes were on Plocamium 
coccineum. Fragments of the algz, encrusted by AL pilosa, 
when mounted in balsam show important details of \ the 
structure of the polyzoon. 
Genus MICROPORELLA Hincks (p. 204). 
15. Microporella ciliata Pallas. 
B.M.P., p. 206, pl. xxviii., figs. 1-8. 
I am not able to say whether the species is common. 
I only obtained two examples, both on Plocamium coccineum. 
16. Microporella malusii Aud. 
B.M.P., p. 211, pl. xxviii. and pl. xxix. 
Two colonies only on the outer portion of dead oyster shell, 
but beautifully preserved; the Zozcia of the colony are 
scarcely abraded. These examples I got this year, 1891. [ 
have no record of the species in my earlier collections. 
Genus SCHIZOPORELLA Hincks (p. 237). 
17. Schizoporella hyalina L. var. y (tuberculata) Hincks. 
-P., pp. 271-273. 
This beautiful little species is rather abundant on Alge, and 
to the naked eye the delicate colonial growths appear as mere 
white specks on the dark green Algee. Notwithstanding that the 
species is so very common, the forms puzzled me more than 
all the others put together. From the form of the cell, and 
Jan. 1892,
