SL'ini-tossilizcH:! specimens, \\\{\\ but .scant remains of 

 epidermic, have as yet come to hand, and though in ihe 

 opinion ot the discoverer it may be an '"extinct species" (Miss 

 Hickey, in Utt.), we consider the evidence of the fragmentary 

 epidermis militates against this theory. The gradually 

 increasing whorls, club-shaped apex, and absence of any 

 umbilical perforation characterize this species, which differs 

 considerably from any form hitherto known from the South- 

 African region. We place it in the genus Euonyma, recently 

 nionogra})hed * by Pilsbry, who has included in it not only 

 the original sinistral type {E. Iwococ/ilis, M. & P.), but like- 

 wise "Bulimus" turriformis, Krauss, and its allies. Com- 

 pared with its nearest ally, E. UmceoUda (Pfr,), the propor- 

 tionate size of the last whorl is striking. This last S[jecies 

 is, so far as is yet known, cunlined to ^S'utal.
