ZOOPHYTOLOGY. 175 



spine on each angle of the cell, but the small figure (7) is 

 more like B. flabellata, to which it has been usually referred. 

 PaUas describes his CeUularia avicularia with three to five 

 longitudinal series of cells, and a single spine at each upper 

 angle; characters which taken together only belong to 

 B. turbinata, and the general accuracy of his descriptions 

 favour the supposition that he had this species in view ; his 

 var. /3 being probably B. flabellata, to which Crisia flustroides 

 of Lamouroux, and Flustra angustiloba of Lamarck, may also 

 be referred, though the former author describes only a single 

 spine at each angle of the cell : this is likewise the case in 

 Dr. Johnston's description of Flustra avicularia, but his 

 figure more correctly shows two or three spines on each 

 side. The CeUularia avicularia of Van Beneden is evidently 

 B. flabellata. 



B. turbinata appears to be quite as common on the British 

 coast as B. avicularia, if not more so. It occurs principally 

 within tide-marks, or in shallow water. The finest speci- 

 mens I possess were got under stones at low-water mark in 

 the island of Herm. They were of a deep orange colour 

 when alive. I have met with it at Guernsey and in the 

 Menai Straits, and have had it sent from Falmouth by Mr. 

 Cocks. Mr. Hincks informs me that it is the common species 

 on the Devonshire and Yorkshire coasts ; and Mr. Busk has 

 favoured me with the examination of a specimen sent from 

 Tenby by Mr. Dyster. It has not yet occurred on the 

 Northumberland coast, nor can I trace it into Scotland, 

 but it would be premature at present to fix any limits to 

 its range. 



On some New British Polyzoa. By the Rev. T. Hincks. 



The new British Polyzoon which I am about to describe 

 is, in many points, so nearly related to the well-known 

 Scruparia chelata, that I have determined to rank it in the 

 same genus with this species, although the generic character, 

 as given by Mr. Busk in his ' Catalogue,' must be revised to 

 allow of its admission. 



Polyzoa Infundibulata. 

 Sub-order. Cheilostoviata. 

 Fam. Scrujianadce. 

 Gen. Scrujiana (Oken). 

 Polyzoary erect, braueliiug, siibcalcareous ; cells clavate ; apertures on 

 one aspect, oblique, subteriiiinal.
