This large species most resembles E. Planti, Pfr., amongst 

 Natalese En/iea;, but differs in possessing a tooth on the outer 

 lip.

Shell sinistral, fusitbrm, the upper whorls somewhat at- 

 tenuate ; whorls thirteen in number, mostly very narrow, 

 broadening distinctly towards the base. The specimens 

 (two) before us being dead, we cannot tell tlie colour, but 

 probably it is pale olivaceous. The whorls are nearly 

 smooth, but are obscurely longitudinally obliquely striate, the 

 basal whorl slightly angled in front ; aperture oblong, tlie 

 columellar margin being straightly produced and slightly 

 retlexed. 



An extraordinary species, utdike any member of the 

 genus that we are acquainted with. Our specimens, though 

 dead, and consequently imperfect, yet show very clearly 

 all the peculiarities of its conformation. 



The superficial resemblance to the Cerithioid (marine) 

 Livi cochli's (/ranosa , S.Woodw., has suggested the trivial name. 

 Although we have only seen two specimens, we understand 

 many more were collected. 



Fseudohalea dominicensisy Shuttleworth, is sinistral, but 

 S. IceocochUs does not belong to that subgenus. Should sub- 

 sequent researches justify the erection of a separate genus or 

 subgenus for this very remarkable sinistral form, based upon 

 the characters as just given, we would suggest the name 

 Euonyma* for its reception. 



Suhulina crystallina, sp. n. (PI. XVI. fig. 4.) 



S. testa pervitrea, gracillima, tenuissinia, nitida, omiiino laevi : an- 

 fractibus undecim, ad suturas impressis, rectis, seusim accres- 

 ceutibus, ultimo paullum producto ; apertura parva, ovata ; 

 peristomate tenui, simplici.
