152 PLIOCENE MOLLUSC A. 



obscure longitudinal plications, by very faint spiral stria? and by the flexuous lines 

 of growth ; suture deep ; mouth ovate, angulate above ; outer lip regularly curved ; 

 inner lip not wholly adherent to the pillar; canal wide, open, very short, turning 

 to the left. 



Dimensions. — L. 42 mm. B. 21 mm. 



Distribution. — Not known living. 



Fossit : Butleyan Crag : Butley. 



Bemarks. — The present shell is from the Ipswich Museum. It belongs to the 

 A. ait IIS group, but differs materially from the specimens of that form figured 

 above, and from Mr. Friele's specimens of the variety virgata ; Mr. A. Bell, indeed, 

 believes it to be specifically distinct. I adopt for it the above name in acknowledg- 

 ment of his long, conscientious and important work in connection with the Crag 

 deposits. 



Anomalosipho Actoni (S. V. Wood). Plate XV, fig. 12. 



1870. Trophon Actoni, S. V. Wood, Mon. Crag Moll., 2ud Suppl., p. 25, tab. ii, %. 13. 



Specific Characters. — Shell bucciniform, turreted; whorls 6 or 7, convex, 

 obtusely angulate with a squarish shoulder above, the last much the largest ; orna- 

 mented by well-marked but rather irregular spiral lines and by a few nearly 

 obsolete longitudinal plications ; suture deep and channelled ; mouth ovate ; outer 

 lip expanded, regularly rounded, forming an obtuse angle with the body-whorl ; 

 inner lip a thin glaze adherent to the pillar ; canal very short, wide, open. 



Dimensions. — L. 32 mm. B. 16 mm. 



Distribution. — Not known living. 



Fossil : Waltonian Crag : Little Oakley. Butleyan : Butley. 



Remarks. — An imperfect specimen from Butley was figured by Wood in 1879, 

 but not described. I have since found another at Oakley which shows the complete 

 mouth. As this form is unknoAvn except for these two fossils, I give it again to 

 show the other side of the shell. It seems specially characterised by the squared 

 outline of the whorls and the wide shelf below the suture.
