STROMBINA. 187 



C. RECURVA, Sowerby. PL 60, figs. 3, 4 ; PL 61, fig. 7. 

 Shell yellowish white, more or less stained with chestnut. 



Length, 1-1-1 -5 inches. 



W. Coast of Central America. 



With this I unite C. lanceolata, Sowb. (fig. 4), and C. fusi- 

 formis, Hinds (fig. 7), the distinctive characters of those species 

 being included in the range of variation exhibited by a large 

 series of C. recurva. 



C. TERQUEMI, Jousseaume. PL 61, fig. 8. 



Shell yellowish brown ; whorls eight, the first four rather 

 smooth, the others longitudinally costate and spirally striate, 

 the last gibbous above, the costae disappearing below the 

 shoulder on which they form tubercles ; lip thickened externally, 

 bituberculate within. Length, 19 mill. Habitat unknown. 



Described from a single specimen in Dr. Jousseaume's col- 

 lection. 



C. PUMILTO, Reeve. PL 60, fig. 6. 



Shell fusiform, thick, rather gibbous, spire turreted, whorls 

 rudely angled and noduled, nodules on the last whorl swollen, 

 irregular; whitish, faintly tinged with orange-brown; aperture 

 narrow, lip thickly varicose, obtusely denticulated within. 



Length, '75 inch. Cumana, Venezuela (Dyson). 



Very closely allied to C. recurva, but of shorter growth, more 

 humped, and more irregularly noduled ; and from its habitat 

 there is also reason to believe it distinct. The figure represents 

 a reversed specimen and it is (except that of C. nivea) the only 

 reversed figure that I have noticed. The above description is 

 copied from Reeve -, the locality is very doubtful. It appears to 

 be closely related to C. Terquemi, Jouss., described above.
