12. F. MORELETI Pallary. PL 52, fig. 2. 



Mr. Pallary believes the form figured by Morelet to be dis- 

 tinct from F. forbesi, by its arcuate outer lip and regularly 

 coiled spire. Morelet describes it as "cylindric, smooth, very 

 bright, of a fawn or russet shade, with a rather obtuse spire ; 

 5 to 6% whorls, noticeably convex, the penultimate a little 

 swollen ; the convolution is regular, without marked deviation 

 of the sutural line, which is accompanied by a dark border 

 as in most species of the genus. The straight, short and thin 

 columella runs into the basal margin, without any appearance 

 of truncation. Length 8, diam. 3.5 mm."

"F. abromia is distinguished from vescoi, proechia etc. by 

 its more regular increase, the shell noticeably 'Costulate, the 

 last whorl a little hollowed out towards the outer margin, in- 

 stead of being nearly flat as in vescoi, or convex as in proechia ; 

 by the straight columella, not callous or twisted, etc. Length 

 11, diam. 3.5, aperture 4 mm." (Bgt.).

Bourguignat states that this species lives also in Sicily, but 

 according to Cafici, this has not been confirmed by Sicilian 

 naturalists.
