308 PYRAMIDELLIDiE. 



rather produced and peaked subovate form, is regularly 

 contracted above to a very acute angle, and is somewhat 

 narrowly rounded below, where it is a little disposed 

 to expand. The outer lip, which advances at the base, 

 is simple, acute, and somewhat arched, but much more so 

 below than above ; owing to the comparative straightness 

 of the columella, which is still, however, a little curved, 

 its union with it forms a blunt or rounded-off rectangle. 

 There is a peculiar inward twist, but no apparent fold, at 

 the origin (or posterior end) of the pillar lip ; this last forms 

 only one-half of the inner lip (the upper portion of which 

 is convex) and is erect and peculiarly narrow, but even- 

 tually becomes a very little reflected. There is no true 

 axial perforation, but only an indentation of the surface 

 behind the pillar lip. Montagu obtained the specimen 

 from sand in Salcombe Bay, South Devon, and states that 

 the breadth is scarcely one-third of the length which latter 

 is fully the eighth of an inch. 



Note. — Wc have never met with the following shell, but judging from its figure 

 it must be distinct from any we have noticed. It is stated to have been picked 

 up by the author from the beach near Montrose.
