 Mr. Smith who compared it for me, says it is allied to bul differenl from angusta Smith 

 (Ann. Mag. Nat. llist. Srr. 4, Vol. XIX, [877, p. 495); that species is still narrower, has a 

 considerably larger number of ribs on last whorl (15) and has 5 or 6 spiral grooves on upper 

 whorls, with 5 or 6 nodules on rihs, (only 2 <>r 3 in the new specii

The specimen is smaller (tó Mill.) but otherwise agrees rather well with figure E 1 of

This specimen, also identified by Mr. Smith, is smaller (19 Mill. instead of 25) probablv 

 net full-grown, with the lirations less numerous, as it is moreover bleached, (though light yellowish- 

 brown) and not (piite typical, it is unfortunately not fit for figuring this still unfigured species.

Shell fusiform, rather solid, uniformly red-brown, lighther behind peristome and at the sutural 

 sinus, and with orange base. Whorls 6, (apex broken; the number of whorls may have been 

 at least 10) rather convex, slightly excavated below the conspicuous suture, which is accom- 

 panied by an inconspicuous infrasutural thread. Sculpture consisting of somewhal oblique ribs, 

 neari ing the entire whorl in the upper ones, but becoming obsolete in the infrasutural 



■il of lower whorls, about 15 ribs on last whorl, of which the ventral ones are obsolete, 

 that behind the peristome very strong, varix-like, moreover the shell is covered with fine 

 and very fine spiral striae, only visible under a lens, 6 spiral lirae cross the ribs, 

 in m with intermediate, much finer lirae and 3 to 4 very faint ones in the excavation ;
