324 CYLICHNA. 



C. GRANOSA Brazier. Unfigured. 



Shell small, ovate, light straw yellow, variegated with two nearly 

 obsolete white bands, in some specimens not visible, contracted 

 above, produced and rather acuminate below ; longitudinally and 

 transversely rugosely striated, interstices smooth, the whole surface 

 of the shell having the appearance of somewhat square-like grains, 

 spire conspicuous in the deep umbilicus of the apex, outer margin 

 of the umbilicus white and very rugose ; aperture narrow, acumin- 

 ately produced and thickened above, slightly produced below ; col- 

 umella thickened, straight, slightly reflected, umbilicus minute, 

 with a white margin, peristome moderately inflexed. Length 2 

 lines, breadth 1 line (Braz.). 



Darnley Island, Torres Straits, SO fathoms. 



Mnestia granosa BRAZ., Proc. Linn. Soc. N. S. W. ii, p. 81, 1887. 



The whole surface of this species is covered with a series of small 

 grains, after the style of a double cut file (Braz.). 



C. PUNCTOSULCATA E. A. Smith. Unfigured. 



Shell wide ovate, a little narrowed at the base, thin, scarcely pel- 

 lucid, brown-white, transversely delicately sulcate, sulci 27, equi- 

 distant, closely punctate. Vertex umbilicate, striated within, sur- 

 rounded by a rounded margin. Aperture wide, a little produced 

 above the vertex ; lip thin ; columella thickened, sinuous ; umbili- 

 cal region subperforate. Alt. 4, diam. 3 mill. ($m.). 



Tunis, North Africa. 



C. (Mnestia) punctosulcata SM., Ann. Mag. N. H. (4), ix, p. 353. 



This appears to be very distinct from any other species ; and it 

 is at once recognized by the 27 closely punctured striae, which are 

 at equal distances from each other ($ra.). 



C. ALBOGUTTATA E. A. Smith. Unfigured. 



Shell ovate, somewhat attenuated at base, thin, semipellucid ; 

 whitish, closely ornamented with opaque milky spots ; smooth, shin- 

 ing, finely striated with growth lines and transverse lines, more dis- 

 tinct above and at the base. Vertex deeply umbilicated, trans- 

 versely striated within, surrounded by a rounded margin ; aperture 

 rather wide above, wider at base ; lip thin ; columella thickened, 

 white, reflexed, nearly closing a small fissure. Alt. 8, diam. 4J 



mill. OSWi.).
