VOL. XVIII. (i) INFERIOR-OOLITE ECHINOIDS 75 



REMARKS ON THE SPECIES 

 ACROSALENIA 



A single specimen, too imperfect for specific determination. 



Top-Beds (schlcevbachi), Broadwinsor, near Beaminstcr. 



CIDARIS BOUCHARDI Wright. ' 



In our main paper specimens of this echinoid w^ere re- 

 corded (p. 165) from the Doulting Stone of Vallis Vale, near 

 Frome, and — on the authority of Wright — from the " Parkin- 

 soni Zone " of Bridport. 



It is now possible to add that this echinoid is by no 

 means infrequent in the Top-Beds {truellei-schlcenbachi) of the 

 Crewkerne-Burton-Bradstock district and more particularly 

 in the rock of the later hemera. 



Top-Beds (portion of schlcenbachi date). — Allotment and Larkfield 

 Quarries, Burton Bradstock ; Peas-Hill Quarry, near the New 

 Inn, Sliipton Gorge ; " Garden Section," Sliipton Gorge ; Loder's 

 Cross ; Vinney Cross : (portion of triiellei date) North Perrott, 

 near Crewkerne : /Gayaiitiaiiri-Hodii, quarry near the Keeper's 

 House, Hinton Park, Dinnington, near Crewkerne. 



CIDARIS CONFLUENS Wright ex Forbes MS.' 



The worn portion of a Cidaris, upon which this species 

 is founded, is in the Museum of the Geological Survey at 

 Jermyn Street [Reg. No. VII ^\\. It is labelled as having 

 been obtained from the " Inferior-Oolite, Sunny Hill House, 

 Frome." It must have come from the Top-Beds, as they are 

 the only Inferior-Oolite strata present in the neighbourhood 

 of Frome and probably from the portion of either tniellei 

 or schlcenbachi date. 



It is impossible to say more concerning the specimen than 

 that it may -be a worn portion of Cidaris bouchardi Wright. 



CIDARIS YEOVILENSIS Wright.^ 



The " type " is in the British Museum, South Kensington 

 [Reg. No. E. 1660], and is labelled " Inferior-Oolite, Yeovil," 

 The specimen consists of a single radiole, and it is probable 

 that it came from one of the hard beds in the Yeovil Sands 

 (of about nioorei hemera) [E.T.P.].
