This species has somewhat of the opalescent character of the 

 preceding. In some of the old specimens there is a small bluni, 

 tooth cn the inner surface of the body vvhorl within the aperture 

 and just above the columella ; but this is by no means a constant 

 character. — W. J. B. 



BuLiNus TRANSLUCENS. BuL testd oblongo-pyramidali, levissim^ 

 transversim striatd, pallide Jlavd, valde pellucidd; arifractibus 

 quinque, subventricosis : long. |, lat. į poli. 

 Hab. in America MeridionaU, arboribus adhaerens. (King's and 



Saboga Islands, Bay of Panama.) 

 This elegant Bulinus, when in fine preservation, is so translucent 

 that the internai pillar and structure of the shell may be plainiy 

 vievved through its glassy surface. Likę many other transparent 

 shells, this species, when it has been long vveathered or dead, becomes 

 of a white hue and much more opaque. — W. J. B. 



BcLiNUS GUTTATU3. Bul. testd fusijovmi , psllucide Juscd, guttts 

 lineisque longitudinalibus albis varid ; arifractibus sex ; apice 

 papillari et guasi elephantino : long. -J-, lat. į poli. 

 Hab. in Peruvia. (Cobija or Puerto De la Mar.) 

 The termination of the spire in this pretty and transparent spe- 

 cies is somewhat abrupt, and the ivory-looking apex is almost as 

 papillary, and appears almost as opaque, as that of a Turbinella. —
