thirty miles northeast from Aux Cayes, and I sent specimens 

 to Dr. Pfeiffer, who described it in 1866. 



Mr. V. P. Parkhnrst, during his late visit to Haiti, collected 

 a considerable number of specimens near Port an Prince. 



The aperture of //. intusplicata is described as "parum 

 obliqua, semiovali-subtriangularis, altior quam lata, ad colu- 

 mellam angulata et plica intus fere ad marginem decurrente 

 munita," of //. SmitJnana as "obliqua, late semiovaiis, juxta 

 columellam plica approximata, parallela canaliculata." 



Specimens received from Messrs. Smith and Parkhnrst 

 agree with each other, slightly varying in size only, and with 

 the figures of Sowerby and Reeve.

I am indebted to Mr. Parkhnrst for one dead specimen, 

 found near Port an Prince, Haiti. 



Pfeiffer was ignorant of the habitat, but by Sowerby and 

 Reeve this species is assigned to St. Domingo under the 

 name of Cumingii, the latter erroneously referring to the 

 Zool. Proc. of 1845. 



The species is readily identified by its well developed 

 striae, subangular periphery, etc. 



Among other species, also collected by Mr. Parkhurst 

 near Port an Prince and in its vicinity, were Cyclotus Jlocco-
