This form of gastropod is represented by a fragmentary limestone- 

 cast, exhibiting the penultimate and last whorls of a large shell of 

 ovately-conical shape. The last whorl is convex, long, and sur- 

 mounted by a somewhat flattened area, bordered by an angulated 

 margin. The umbilical region is excavated, although partly filled 

 with matrix; and the aperture is of distinctly-oval contour, vertically 

 elongate, narrow, with nearly-parallel sides, and showing a 

 measurement of 63 by 35 millimetres. 



The specimen has all the appearance of a close relationship to 

 Euspira scalariformis, having been probably furnished with just 

 as prominent a spire as that which characterizes that species when 

 in a more perfect condition. The species was originally recorded 

 from the Middle Eocene of France. 



Locality. — Near Berbera. 



Collector. — Dr. Donaldson Smith. Presented to the British 

 Museum (Natural History) by the Gaekwar of Baroda. 



Matrix. — Greyish cherty limestone.

This specimen was originally recognized as Cretaceous, under 

 the name of Natica allied to Hugardiana, but it is apparently a 

 form not far removed from Euspira hybrida, so characteristic of 

 most Eocene localities. It shows a graduated and conical spire 

 with the prominent ' rampe ' or platform constituting the summit- 

 area of each whorl. The last whorl is inflated, and excavated at 

 the base, where there are indications of a large rounded callosity. 

 The aperture is semi-oval. Parts of four whorls are traceable in 

 this cast, the more delicate earlier ones not, of course, being 

 present.

There is also a smaller cast, which may be referred to this 

 species.
