declivi<. annulo crasso cincta : margine laterali subplanato ; oper- 

 culo ? Long. 2; diam. .3 millim. Inhabits China Seas. W. S. 



The only specimen found is worn and defective, hut clearly 

 distinct from any yet described. It is most like C. pulcherrimum, 

 hut is more slender and has the rings closer. It belongs to 

 the group Anellum of Carpenter, the best authority on this genus, 

 and to whom 1 am obligated for determining this species. 



Another species closely resembling C. elongatum, but too 

 young and imperfect for description, was obtained. These are the 

 only specimens yet noted from the Japan or China seas, where 

 they seem to he much more rare than in tropical American waters. 



IIyala abxormis. T. pupaeformis, hyalina, tenuissima, stra- 

 minea, valde distorta ; nucleo celato, declivi ; anfr. 4 nonconforms 

 bus, posticis cito crescentibus subangulatis, ultimo cylindrico, elon- 

 gato antiee contracto ; sutura profunda, quasi incisa. Apertura 

 suhrotunda, effusa; columella plica postice munita. Long. 1.7; 

 lat. .6 millim. Inhabits China Sea ; coral regions. 



This very curious little shell, so remarkable for its short, dis- 

 torted spiie and deep suture, if not a distinct genus, is allied to 

 Stylifer, and may for the present he assigned to this genus or to 

 the subgenus Auriculina, Gray, which seems to be equivalent to 

 Jeffreysia or Rissoella, Odostomoid shells without a folded lip ; 

 though I think a distinct posterior fold is to be made out in this 

 specimen. The animal alone can settle its true position. 



Cheletropis globosa. T. minutissima, pellucida, lasvis 

 tenuissima; nucleo declivo, celato ; anfr. 4 tumidis; sutura per- 

 spicua. Apertura ovata (?) ; peritremate continuo ; columella, 

 valde sinuata (forsan plicata). Axis 1 -4- ; diam. 8 millim. In- 

 habits China Seas. W. S. 



Two specimens of this very minute shell, quite fresh, were 

 obtained, both having the aperture somewhat fractured. Its gen- 

 eric place is doubtful. The somewhat beak-like prolongation and 

 its tenuity seems to attach it to this genus, which is considered to 

 be a Pteropod. If it does not belong here, it must be allied to 

 the preceding shell. 



Carinaria cornucopia. T. parva, hyalina, elongata, sub- 

 triangularis, compressa, plicis angulatis reclivibus ad cristam
