344 PLIOCENE MOLLUSCA. 



Distribution. — Not known living. 



Fossil: Coralline Crag : Boy ton. 



Remarks. — This shell was originally described by Wood from a Coralline Crag 

 fossil obtained at Boyton. There are two examples of it, one being now figured, 

 at the British Museum (Nat. Hist.), which have been labelled Murex Canhami. 

 Wood's type specimen of the latter, however, came from the Newbournian Crag 

 of Waldringfield. It is much smaller, differing from the present species both in 

 form and sculpture. 



Wood states that he had compared his type fossil with specimens of M. Nijstii 

 from the Miocene of Belgium, but that although they approach in certain respects 

 they are not the same. 



There is an example of the latter in the Norwich Museum which bears out 

 Wood's opinion. 



Var. similis, nov. Plate XXXV, fig. 13. 



Varietal Characters. — Agrees generally with the type form of 0. pseudo-Nystii, 

 but is larger, the sculpture is coarser and the varices are more distinct. 



Dimensions. — L. 30 mm. B. 16 mm. 



Distribution. — Not known living. 



Fossil : Waltonian Crag : Little Oakley. 



Remarks. — I have two or three specimens of this variety in my collection from 

 Oakley. It seems to be an intermediate form connecting 0. pseudo-Nijstii and 

 0. tortuosa.

Specific Characters. — Shell fairly large, thick, fusiform; spire elevated with an 

 acute apex; whorls 7, sub-angulate, the last much the largest; varices thin, 

 foliaceous, with projecting spines on the angulated part of the whorls, distant on 

 the last, closer and more numerous on the upper ones; spiral sculpture wanting 

 or obsolete; mouth oval; outer lip thickened by the labial varix, denticulated 

 within ; canal rather long, narrow, oblique, nearly closed ; columella flexuous. 



Dimensions. — L. 40 mm. B. 20mm. 



Distribution. — Not known living. 



Fossil : Coralline Crag : Boyton. Waltonian : Walton-on-Naze, 

 Little Oakley. Butleyan : Butley (Kennard). 



Remarks. — This species was known to Wood from a unique specimen obtained
