ZOOPHYTOLOGY. 



Descriptions of New Species of Polyzoa. Collected by 

 George Barlee, Esq., in Shetland. 



The assiduous dredging labours of Mr. Barlee, more espe- 

 cially in the Northern seas of Scotland, have, as is well 

 known, been the means of introducing numerous additions 

 to the British Marine Fauna, among which, those belonging 

 to the domain of Zoophytology are by no means the least 

 considerable. Having been favoured by Mr. Barlee with the 

 opportunity of examining the Polyzoa collected by him 

 within the last two years, we here commence the description 

 of the new or imperfectly known species comprised among 

 them. As these are numerous, and our limits, so far as 

 illustrations are concerned, circumscribed, the description of 

 these species will occupy several numbers of the journal, 

 although, in the meanwhile, brief descriptions of most of the 

 new forms were presented to the British Association at its 

 late meeting. 



Sub-order. Cheilostomata. 

 Fam. 1. Flustridce. 

 Gen. 1. Flustra. Linn. 

 1. F. Bar lei, n. sp. PL XXV, fig. 4. 



F. polyzoario foliaceo, diviso, lobato ; cellulis oblotigis, margine simplici ; 

 ovieellulis cucullalis ; aviculariis intercellulas sparsis, oblique positis, man- 

 dibulo semicirculari. 



Cells oblong, with a simple margin; ovicells shallow, cucullate ; avicularia 

 few, scattered, placed obliquely, and having a semicircular mandible. l 3 oly- 

 zoarium foliaceous, divided, lobate. 



Hab. Shetland, Barlee. 



The polyzoarium of this species bears a close resemblance 

 to some conditions of Flustra foliacea ; but, when examined, it 

 will at once be seen to be wholly distinct from that and all 

 other hitherto described species. The cells are of the same 

 oblong, rectangular shape as those of F. papyracea and F. 

 truncata, and, as in those species, wholly membranous in 

 front. F. Barlei differs, however, from both, in the far 

 larger size of the cells, which is at least double that of the 

 cells in either of the species named. The margin is wholly
