APPENDIX. 



Here follow a few species, which have been found in tubes or boxes and have been 

 overlooked, partly because they were concealed in the aperture of larger species, partly by their 

 real affinïty not having been recognized, when the collection was provisionally arranged in 

 larger and smaller groups; so for instance those now recorded as Trop/wn, which, with their 

 damaged peristomes made the impression of belonging to the Pleurotomidae, until a closer 

 examination, broucjht to light the total absence of the characteristic sinus.

 1 Spec. 



Shell quoit-shaped, strong, light yellowish-white. Whorls 4, rounded, separated by a deep 

 suture; spire scarcely raising above last whorl, first whorl vitreous, nearly smooth, last whorl 

 and a small part of penultimate one, with numerous, raised, spiral striae on a zone at the suture ; 

 at the rounded periphery and in the wide umbilicus they are coarser than on the two inter- 

 mediate zones, where they are extremely fine ; they are crossed by growthdines, stronger towards 

 aperture. Aperture transversely oval, peristome thick, upper margin protracted in a peculiar 

 trigonal wing. Umbilicus wide, pervious, funnel-shaped.

This species, by its winged peristome, reminds C. euchilopteron Melv. (Ann. Mag. Nat. 

 Hist. Ser. 7, Vol. XIII, 1903, p. 292, PI. 20, fig. 7), especially if seen from below, but is quite 

 different by its wanting of keels, other particulars of sculpture, size etc.
