A rare but extremely well marked species, of which but few 

 examples have been found. Its chief peculiarity is that the 

 beak is placed so far back, as is well shewn in Mr. Davidson's 

 figures, and this, as well as the shape, serves to distinguish it from 

 any other species. It approaches most nearly to Tereb. decipiens, E. 

 Desl. One young specimen of Tereb. Craneae in my collection 

 from Oborne has the peculiarity of the beak well brought out, 

 as both the valves are, as nearly as possible, the same length, 

 the foramen being on the very top of the shell. Tereb. Craneae 

 was figured by Szajnocha as new, under the name of Tereb. 

 hungarica, Suess., and he figures the young (see synonyms) in 

 plate i., figs. 1 and 2. 



Localities. (British) Oborne, and near Half-way House, Dor-

A species at once separable from Tereb. sphaeroidalis, Sow., by 

 the lesser convexity of its valves, its much greater length and
