DESCRIPTIONS OP NEW SPECIES OF MARINE GASTERO- 

 PODiB INHABITIN& POLYNESIA. 



BY WM. HARPER PEASE. 



TEREBRA. 



Thirty-two species of the above genus are known to me as 

 inhabiting the Hawaiian Islands, sixteen of which have not been 

 found elsewhere. Having made lately a critical examination of 

 all specimens collected by me, I am able to add nine species to 

 those previously described. 



I discover that the synonymy of T. Peasii, Desh., as pub- 

 lished by me, was incorrect. I was led into the error by follow- 

 ing the name attached to the typical specimens forwarded me. 

 That species is without doubt a synonym of T. puncticulata, 

 Desh., and the species mistaken for it is a variety of T. Swain- 

 sonii, Desh., departing so widely from the type that I distinguish 

 it by a distinct name, as follows : 



T. Swainsonii, Desh., var. injlexa, Pease. 



The ribs on the type are straight, and interstices, especially 

 on the upper whorls, faintly and remotely striate transversely. 



The ribs on the above variety are flexuous, interstices im- 

 pressly striate or grooved throughout, and whorls shorter. The 

 shell is usually longer. The figure and description of T. 

 Swainsonii in Conch. Icon., are taken from a specimen of the 

 above variety. 



T. scuLPTiLis, Pease. 



T. elongato-turrita, gracilis ; anfr. 15, superne costa, nodosa, 

 conspicua, cingulatis, utrinque sulco marginata ; anfractibus 

 concave -excavatis, longitudinaliter arcuato-striatis, superne 

 juxta sulcum nodoso-crenulatis ; apertura parva, oblonga, colu- 

 mella contorto-recurva ; costa alba, interstitiis pallide straminea.
