This is a rare species in Costa Rica, our collection containing 

 only a single specimen from the Gatun beds of the Rio Blanco. 

 It is characterized b}' a rather high, conic spire, with smooth or 

 only slightly coronated whorls. The last whorl has about iS, 

 wide, spiral bands, which are heavily granulated above. The 

 specimen agrees well with Guppy' s fi.gure of the Jaraaican 

 shell. 



Length 25, breadth 11 mm.

The occurrence of this species in Costa Rica is limited to 

 the coral limestones of Limon, Gabb had specimens from here 

 which he identified with the recent West Coast Conus rcgzilaris 

 of Sowerby. The Limon shells agree very well with Guppy' s 



figure in the Quarterly Journal and with Cossmann's figures of 

 Bowden and Mindi specimens. The species appears to be clo.sely
