much larger, the lines of growth are very slight, and the 

 equidistant transverse striae which are over the whole surface 

 at once separate it. 



Haminea rugosa. B.M.

 lariter rugosa ; vertex parum depressus ; apertura latiuscula, basi 

 dilatata ; labium tenue, superius subangulatum verticis medio 

 junctum; columella brevis, reflexa, rimam parvam fere tegens,

 It is peculiar for the longitudinal in*egular wrinkles formed 

 by occasional deep lines of growth.

 indistincte et transversim superne basique striata ; vertex exigue

 labrum solidum, crassum ; columella crassa, medio dente parvo 

 vel tuberculo munita ; umbiHci regio subperforata.

Hah. Fiji Islands. 



A small, semitransparent, bluish-white species, chiefly cha- 

 racterized by the thick labrum and columella, which has a 

 small tooth or tubercle on the middle of it. 



Cylichna propinqtia. B.M. 



C. testa elongata, cylindracea, paululum medio contracta, alba, epi- 

 dermide palUde brunnea, quae superne inferneque brunnior est, 

 induta ; transversim exUissime undulatim striata ; vertex exca- 

 vatus, medio anguste perforatus, margine acuto succinctus ; aper-

 paraUelum ; columella spiraliter tortuosa.

Hah. Vancouver's Island. 



This species in general aspect reminds one of the common 

 C. arachis, Q. & G. ; but it is considerably narrower, with the 

 vertex only excavated with a minute perforation, not umbili-

 cate.
