24 THE BRACHIOPODA. 



" Brachipodes," and they are also not so angular as his figures. 

 This species has a furrow down each valve, and is crossed by 

 transverse lines of growth, between which occur a very large 

 number of minute punctuations. 



Dimensions. Length 9, breadth 7, depth 5 lines. 



Localities. (Britain) Bradford Abbas (Dorset). I believe 

 that it has not been found anywhere else. (Foreign) at Ste- 

 Honorine des Perthes (Calvados).

TEREBRATULA HYBRIDA, E. Desl., Brachiopodes Terr. Jurass., 

 plate Ixvi., fig. 1-6. 



This little species, allied to Tereb. Morieri, was first found for 

 Britain at Broadwindsdr (Dorset) by Mr. D. Stephens and 

 myself. It is distinguished from Tereb. Morieri by being slightly 

 broader in proportion, and in having tranverse and longitudinal 

 lines crossing each other, thus giving it somewhat the appear- 

 ance of trellis work. This structure of the shell is well shown 

 by E. Deslongschamps in " Brachiopodes," plate Ixvi., fig. 6. 



Dimensions. Length 7, width 7, depth 5 lines. 



Localities. (Britain) zone of Parkinsoni, only at Broadwindsor 

 (Dorset). (Foreign) E. Deslongschamps says " This species 

 has only been found in one locality, at Sainte Honorine des 

 Perthes, near Port-en-Bessin (Calvados), in white oolite, that is 

 the Am. Parkinsoni bed."* 



20. TEREBRATULA CONGLOBATA, E. Desl. 



TEREBRATULA CONGLOBATA, E. Desl, Brach. Jurass., plate Ivii. 



At present very rare in this district. It seems to be distin- 

 guished by its tendency to form extra biplications. Judging 

 from the various figures given by E. Deslongschamps, it seems 

 to be very variable and hard to define. I possess two specimens
