VOL. XVII. (2) POLLICIPES IN THE INFERIOR OOLITE 275 



ON THE OCCURRENCE OF POLLICIPES 

 IN THE INFERIOR OOLITE 



BY 

 THOMAS H. WITHERS, F.G.S. 



A single imperfect plate (tergum) of a Cirripede, found by 

 Miss H. M. Hutton in the Lower Limestone, Inferior Oolite 

 (Aalenian), of Well House, Haresfield Hill, near. Gloucester, 

 was described and figured by Mr L. Richardson' in 1908, 

 under the name Pollicipes aalensis. Attention was again 

 called to this specimen in 1909,^ but nothing further was 

 added to the previous account. 



Since it might be inferred that this is the first record of 

 a Cirripede from the Inferior Oolite, it may be advisable to 

 point out that more than fifty years ago, the late Rev. P. B. 

 Brodie called attention^'*'^ to certain remains of Pollicipes 

 which he had collected from the Inferior Oolite at Selsley Hill, 

 near Stroud. These remains consisted of two scuta and 

 three fragments of other valves, and it is to be regretted that 

 they were not described or figured, since it is not unlikely that 

 they may have belonged to the same species as that described 

 by Mr L. Richardson as P. aalensis. 



The greater portion of the collection of the late Rev. 

 P. B. Brodie was acquired by the British Museum (Natural 

 History) in 1898, and although careful search has been made, 

 the above Cirripede valves do not appear to be among them. 



In the Geological Survey Museum, London, the writer 

 has observed five valves (2 scuta, 2 terga, and a carina) from 

 the Inferior Oolite of Great Ponton, Grantham, Lincolnshire, 

 registered 25539 to 25543. The terga agree well with the type 

 of Pollicipes aalensis, and since the other valves are orna- 

 mented similarly, they very probably all belong to the same 

 species.
