families. T. glohata has mucli tlie appearance of my T. with- 

 ingtonensis *, but is much more tumid. It lias the same 

 peculiarly truncate beak. 



This identification of T. glohata leads to the following 

 change of name : — 



Terehratula nunneyensis^ nom. nov. 



1878. T. (jlohata, Dav. (non Sow.) Ool. & Lias, Brach., Suppl. 

 pi. xvii. 3. 



Much more plicate, but much less tumid than T. glohata. 

 Common in the Fuller's Earth. 



Various Cotteswold Inferior Oolite Terehratulce were 

 identified by Davidson with T. glohata ; but of late years it 

 has generally been recognized that they themselves require 

 to be separated as well as parted from T. glohata=T. nun- 

 neyensis. They and T. nunneijensis belong to the same 

 group ; but the true T. glohata belongs to quite a different 

 series — that of T. sphceroidalis. 



Terehratula cotteswoldensis, nom. nov. 

 1878. T. glohata, var., Davidson (non Sow.), Suppl. pi. xvii. 1. 

 Like T. intermedia, Sow., but more plicate and much more 

 tumid. Common in Clgpeus-gvit of the Cotteswolds. 



Terehratida cheltensis, nom. nov. 



1878. T. globata, Davidson (non Sow.), Suppl. pi. xvii. 2 (type) ; 1851, 

 pi. xiii. fig. 7. 



Oppel (Juraf. p. 497) notes how Davidson's pi. xiii. 7 

 differs from his T. Fleischeri. The other figure cannot repre- 

 sent one of Oppel's types, for he does not mention Cheltenham 

 in his list of localities, and T. Fleischeri belongs to the 

 Cornbrash. 



Common in the ChjiJeus-^vit of the Cotteswolds. 



in 



T. birdlipensis, Walker, of which Dav. Suppl. pi. xvii. 18 

 may be taken as type, and T. tumida, Dav., mentioned ir 

 Suj)pl. p. 149 as T. glohata var. tumida, are two more forms 

 of what used to be called the globata-sevies. Presumably the 

 specimens depicted in Ool. Brach. pi. xiii. figs. 5, 6, are 

 what Davidson intended as 2'. tumida : Leckhamptou and 

 Cheltenham are really terras for the same locality.
