﻿CRETACEOUS BRACHIOPODA. 37 



further comparison will, therefore, be needed before T.phaseolina can be definitely admitted 

 as a British species.

Mr. Ralph Tate has found a fine example of this species in the Upper Chalk near 

 Lisburn, County Antrim, Ireland. Others have been collected by Mr. Meyer from the 

 Chloritic Marl of Pinney Cliff and the Grey Chalk near Caterham. The finest and most 

 typical specimens of the species were, however, obtained from the Upper Chalk of 

 Norwich ; and from that locality some very fine examples may be seen in the British 

 Museum.

 I have nothing further to add. 



41. Terebratula PRiELONGA, Soio. Dav., Cret. Mon., PI. VII, figs. 1,2; Sup., 



PI. Ill, figs. 12, 12 a—c, 13. 



Until the year 1867 Terebratula prcelonga was one of our rarest British fossils. It 

 has, however, since then been found to occur abundantly in the Lower Greensand at 

 Upware, in Cambridgeshire ; from which locality large and fine examples have been 

 collected, and of these I have given some illustrations. Mr. Meyer has obtained speci- 

 mens of this species at Shanklin (at the base of the Polkstone beds), and one example 

 in the " Sponge-gravel" of Farringdon. The loop is short and simple. Some specimens 

 are more than two inches in length, by one inch two lines in breadth. This species has 

 been badly understood by French and German Palaeontologists ; the specimens they 

 refer to it belong to other species.
