Dr. J. Gwyn Jeffreys on Mediterranean Mollusca. 399 



I have ventured to dedicate the above briefly described 

 genus to my kind friend and correspondent the Abbe 

 Brugnone, of Palermo, whose discoveries of recent and 

 Tertiary shells in Sicily are or ought to be well known to 

 all conchologists. 



Brugnonia pulchella *, Jeffreys. (PL XVI. fig. 7.) 



Shell forming a depressed cone above and angulated 

 below, moderately solid for its minute size, semitransparent, 

 and rather glossy : sculpture, numerous, close-set and very 

 fine longitudinal and spiral striae, which, by their inter- 

 crossing, make the surface delicately and microscopically 

 reticulated; the longitudinal striae are flexuous; the apex 

 is smooth : colour pale yellowish brown : spire short : 

 whorls 5, slightly convex j the first 4 gradually increase 

 in size, but the last or body-whorl is disproportionately 

 large and takes up about three fourths of the shell ; the top 

 whorl is somewhat twisted : suture well defined, but not 

 deep : mouth triangular, narrowish : outer lip rounded, thin, 

 and sharp-edged, ending above in an acute angle where 

 it joins the periphery, reflected at the other end : inner lip 

 filmy and scarcely perceptible : pillar short and straight, 

 terminating at the base in a slight and open but not chan- 

 nelled groove : base not umbilicated nor perforate. L. 



0-035, B. 0-035. 



Two specimens only, one of them much younger than 

 the other and half its size. 



ddeorbis exquisitus^ Jeffreys. (PL XVI. fig. 8.) 



Shell semispheroidal, expanding laterally, rather thin, 

 transparent, and glossy : sculpture, numerous and extremely 

 delicate curved longitudinal striae or lines, which are crossed 

 by equally numerous and fine spiral lines, causing a most 

 exquisite kind of microscopic decussation ; apex smooth : 

 colour clear white: spire short and compressed, placed ex- 

 centrically : whorls 3, convex and rounded j the last 

 occupies four fifths of the shell; top whorl somewhat 

 twisted : suture deeply excavated : mouth obtusely trian- 

 gular : outer lip semicircular, sharp-edged, inflected above at 

 its junction with the periphery, thickened below : inner lip 

 attached to the periphery, and slightly folded over the 

 base : umbilicus wide, deep, and semicircular. L. 025, 



B. 0-0175. 



A single specimen of this remarkable and beautiful 



species.
