100 BRITISH CRETACEOUS BRACHIOPODA. 



In the Upper Green Sand of Cambridge, a dwarf race of the same species has been 

 plentifully collected by Mr. Carter, and appears to agree in all essential characters with 

 the Speeton Clay specimen, except in dimensions. Mr. Carter considers the shell deno- 

 minated Ter. siiblinearis, by Count Minister, in the Cambridge Museum, to be specifically 

 distinct from the one found in the Cambridge Upper Green Sand. 



I collected the same shell in the Tourtia, near Tournay, in Belgium, it is exactly 

 similar, but a little larger than those commonly met with at Cambridge ; the last are 

 also comparatively much more coarsely striated than the single example I have seen from 

 Knapton, where the species would appear to be very rare.

Aegiope. 



In p. 16 of the present Monograph, will be found described as Argiope decem- 

 costata, Rcemer, Sp., a shell common to the Chalk of England, France, Belgium, Prussia, 

 &c. ; but after the publication of the first portion of this monograph, I was informed by 

 M. de Hagenow, that he still doubted the shells I had figured (PI. Ill, figs. 1, 13), as
