244! CONTRIBTTIONS TO THE BRITISH FAUNAr 



Channel. It has since been found on the English^ 

 shores by the late Mr Bryer, and by Mr Mon- 

 tagu. I observed it among the Zetland Islands in 

 1808. It is thrown ashore in great abundance 

 during the gales of autumn 



Mr Donovan, in his British Shells, has figured 

 a shell which he considered the same as the Lepas 

 fascicularis of Ellis, but to which he gave the 

 name of i. dilata. The figures of the two shells 

 are essentially distinct, and never could have been 

 given as representations of the same species. The 

 pointed reflected apex of the upper valves, so cha- 

 racteristic of the Ellisian species, is not expressed 

 in Donovan's figure, where the apex appears blunt. 

 A short way below the upper extremity of the 

 dorsal valve, there is represented in Donovan's 

 figure, a sudden enlargement of the keel, which 

 continues until the valve bends inwards to join 

 the peduncle. In L. fascicularis, the keel gi'adu- 

 ally increases in size from the upper extremity of 

 the dorsal valve, until it forms a small knob, where 

 the valve bends inwards. Is the Lepas dilata of 

 British Sheijs, therefore entitled to hold a place 

 in the British Testacea? — (Communicated 9th De-
