Family CYCLOPHORID^.

Family TRTINCATELLID^. 



COXIELLA, N.G. 



Shell similar to that of the genus Tomichia, Benson. Operculum 

 concentric, not paucispiral. Animal unknown. 



This genus diifers from Toviichia in having a concentric instead of 

 a paucispiral operculum. It is named in honour of Dr. J. C. Cox, 

 of Sydney, so well known for his writings on Australian Mollusca. 



The name Coxia has already been employed by M. Ancey for a 

 group of HelicidcR., of which Helix Macgregori, Cox, is the type. 



CoxiELLA. STEiATTJLA, Meuke. B.M.

Blanfordia pyrrJwstoma, Cox, op. cit. p. 95, pi. xv. figs. 14, 14^. 



Hab. — Western sandy coast (Menke) ; Cossack west coast (Brit. 

 Mus.) ; Shark's Bay (Cox) ; Adelaide, South Australia (Cox) ; Sand- 

 ridge, Ilobson's Bay (Craven, in Brit. Mus.) ; and Melbourne, Victoria 

 (Co^x). 



The species is quoted by Fischer (Manuel, p. 752) as representing 

 Adams's genus Blanfordia. This is a mistake, for the two species 

 originally placed in that genus by the author of it (Ann. Mag. Nat. 

 Hist. 1863, vol. xii. p. 424) are quite distinct concliologically and 

 in the localities they inhabit. Blanfordia is more terrestrial in 

 its habits, living " on damp banks covered with vegetation in rocky 

 situations near the sea," whereas the present species, Coxiella striatula, 

 appears to be littoral. The peristome in the latter does not exhibit the 

 strong external varix of Blanfordia, the operculum of which is said to 

 be subspiral, whereas that of the present species is concentric. Cox 

 describes it as "paucispiral," but this, I think, must be a mistake, 

 for the opercula which I have examined ai'c certainly concentric, and 

 in Cox's own figure, pi. xv. fig. 13c, no paucispiral element is sliown. 

 The operculum of the type of the genus Tomichia undoubtedly is 

 paucispiral, as described by Benson.
