702 PLIOCENE MOLLUSCA. 



Dimensions. — L. 29 mm. B. 19 mm. 



Distribution. — Not known living. 



Fossil : Waltonian Crag : Little Oakley. 



Remarks. — I describe provisionally and with some doubt the unique fossil here 

 figured under the generic name of Amauropsis. It agrees with A. islandica in 

 some respects, as in its turreted spire, its conspicuously channelled suture 

 and its incurved upper lip. 



The inner lip, however, is abnormal, leaving the umbilicus exposed, but possibly 

 it may have been broken and have made subsequently a false growth. I have been 

 unable to find anything, either recent or fossil, to which it may be referred ; it can 

 hardly be regarded as a variety of A. islandica. 



Amauropsis gracilis, sp. nov. Plate LVI, fig. 25. 



Specific Characters. — Shell ovato-conical ; whorls 5, convex, the last much the 

 largest; spire elongate, ending in a sharp point; suture deep; mouth angulate 

 above, rounded and slightly produced below ; outer lip thin, gently curved ; inner 

 lip oblique, straight; peristome continuous, projecting over the umbilicus, which is 

 small and narrow. 



Dimensions. — L. 22 mm. B. 16 mm. 



Distribution. — Not known living. 



Fossil : Icenian Crag : Easton Bavent. 



Remarks. — This interesting specimen was discovered by Mr. Bell in the Cavell 

 Collection at Framlingham College. It seems to be new, not only to the Crag, but 

 to science. 



Amauropsis Odhneri, sp. nov. Plate LVI, fig. 2(5. 



Specific Characters. — Shell smooth, smaller than A. islandica, and having a very 

 short spire, but otherwise resembling it; whorls 5; apex depressed; suture deep 

 and canaliculate ; umbilicus partly covered. 



Dimensions. — L. 15 mm. B. 12 mm. 



Distribution. — Not known living. 



Fossil: Butleyan Crag: Hollesley. 



Remarks. — The specimen here figured was found by Mr. Kennard at Hollesley. 

 Its deep and canaliculated suture connects it with the northern genus Amauropsis. 

 It is specially characterised by its short spire. Dr. Odhner, to whom I have 

 submitted our fossil, believes it to be an unrecognised species. I describe it as 

 new under his name.
