Collection {Colin.) Museum of Practical Geology, Jermyn Street, 

 London. [Reg. No. 8862.] 



Type-description. — " Gervillia amita : equivalve, smooth, very oblique, 

 both the auricles very much extended and acuminated, the entire figure being 

 very slender." 



Remarks.— Tht label attached to the type-specimen gives 

 the locality as "Nailsworth," which is close to Minchinhampton. 

 The matrix of the specimen, a white oolitic limestone, shows that 

 it could only have come from the Aalenian at that locality. In 

 his list of species from the Oolite Marl, Lycett (" Cotteswold 

 Hills," 1857, p. 56) records G.aurita, and mentions it from no 

 other horizon. Probably the specimen is from the local 

 Nerincea-BeA (Oolite Marl) of the old Scar-Hill Quarry, Nails- 

 worth, whence Lycett obtained so many lamellibranchs [vide 

 L. Richardson, Proc. Cottesw. Nat. F.C., vol. xvii., pt. I., 1910, 



P- 131-) 



Records.— The only record is that of the holotypc from the bradfordensis 

 deposits of Nailsworth.
