50 TttE BRACniOPODA. 



Localities. — Near Gorton (Somerset), somewliat common ; 

 Bradford A'bl)as, Porset, scarce ; and one specimen from Burton 

 Bradstock, Dorset. Mr. E. Deslongscliamps quotes Ter. ovoides 

 from the departments of Sarthe, Meuse, and Moselle. 



56. — Waldheimia Hughesii, Walker. 



1878. Waldheimia Hughesii, Davidson, British Brach., 

 Palseont. Soc, page 174, No. 157. 



Mr. Davidson very tindly sent me an outline drawing of this 

 species, which he quite inadvertentl7 omitted from his plate. I 

 picked up from the Trigonia grit on Leckhampton Hill 

 (Gloucestershire), a few specimens which undoubtedly belong to 

 this si3ecies. From Blackford (Somerset) I also obtained a few 

 specimens of a Waldheimia. Two of these are undoubted 

 Waldheimia Hughesii, the others are slightly broader and flatter. 



I am at a loss, however, to define any distinction between 

 Wald. Hughesii and some of the forms of Wald. ornithocephala, 

 which we have found in the Fullers Earth rock of Milborne 

 "Wick (Somerset), and also from some of E. Deslongschamps 

 figures of Wald. ornithoce])hala in Brach. Jurass., plates 87 and 

 88, noticeably figure 5 on plate 88. 



Locality. — Zone of Parkinsoni, at Blackford (Somerset) ; ako 

 Leckhampton, Gloucestershire. 



57. — Ehynchonella bilobata, n.sp. 



A very few specimens of a peculiar and rare Ehynchonclla have 

 been found in the Sowerbj'i zone, at Bradford Abbas, Dorset, 

 and other places. It was at first referred by Mr. Davidson to 

 Ehynchonclla trigona, Quensted Brachiopoda, plate 40, figure 

 71, but I consider that it differs from it in having a well marked 

 and deepish furrow in the dorsal valve, no ribs at all showing, 

 but only a little notching at the base, and the dorsal valve being 

 convex from the beak to the base. 



In size and shape it mostly resembles Quenstedt's figiu-e 72, 

 but has the thick base of figure 71, with the waved marginal
