THE BKACHIOPODA. 29 



Bradstock in the same place as Dr. Oppel. It is, however, 

 small and not characteristic in the Torulosus bed, but in the 

 Murchisonae zone it is much commoner and finer. It varies 

 slightly in shape, as is well shewn in Mr. Davidson's good 

 figures, and it also varies extremely in abundance. On the rail- 

 way cutting at Bradford Abbas, Dorset, it is extremely common, 

 whilst at East Hill quarry, at Bradford Abbas, only about 500 

 yards distant it is extremely rare. Again at Haselbury, Somer- 

 set, and Drimpton (near Broadwindsor), Dorset, it is very 

 common. This species thickens at the base, sometimes very 

 greatly. 



Localities. (British) Burton Bradstock, Bradford Abbas, etc., 

 Dorset. Haselbury, Somerset ; also Dundry, and Dr. Oppel 

 mentions it from Gloucestershire. 



26. WALDHEIMIA DISCULUS (Waagen). 



1867. MACANDBEWIA DISCULUS, Waagen, Geog. Palaont., Bei- 

 trage, plate xxxi. (8), figures 8 and 9. 



This species was discovered by myself in the Sowerbyi zone in 

 a quarry near Gorton Denham, Somersetshire, and I do not 

 know that it has occurred anywhere else in England. The adult 

 specimens (Waagen plate xxxi, figure 8) are very similar to 

 Wold, anglica (Oppel), but the peculiar raised beak at once dis- 

 tinguishes it. The young might perhaps be taken for the young 

 forms of WaU. sulbucculenta (Chap, and Devalque). Waagen 

 found this species in the Sowerbyi zone. He says that he has 

 six specimens from Gingen (Wiirtemberg), and does not know 

 of it from anywhere else. 



Localities. Near Gorton Denham (Somerset). (Foreign) 

 Gin gen (Wiirtemberg).
