18G2.] MR. W. H. PEASE ON NEW SPECIES OF SHELLS. 243 



Shell slenderly subulate, elongate, white, polished, straight ; 

 whorls numerous, plane, suture very faintly impressed; aperture 

 small, acutely ovate ; columella slightly callous. 



Length 11, width 2^ mill. 



Engina tuberculosa. 



T.fusiformis, utrinque attenuata; spira subacmninata, acuta, lon- 

 gitudinaliter tuherculato-costata ; transversim lirata, liris sii- 

 perne nodosis, interstitiis suhtilissime striatis, nigra; anfractu 

 idtimo albo fasciato ; apice albido; columella postice corriigata, 

 dentieidis j^arvis : apertura alba, longitudinis testes diinidiuin 

 hand cequans. 



Shell fusiform, attenuated at both ends, spire somewhat acumi- 

 nate, acute ; longitudinally tuberculately ribbed, transversely ridged, 

 ridges forming tubercles or nodules on the longitudinal ribs. Inter- 

 stices very finely striated ; aperture less than one-half the length of 

 the shell ; columella-lip corrugate or plicate posteriorly ; teeth small. 

 Colour black, last whorl encircled with a white band ; aperture and 

 apex white. 



Length 9, width 4 mill. 



The smallest species of the genus with which we are acquainted. 

 "We give the size of a large specimen. Y/e have received it from 

 several localities, and find it constant in shape and sculpture. The 

 painting varies, the lower part of the last whorl and the spire being 

 more or less spotted with white in some specimens. 



EUCHELUS MACULOSUS. 



T. parva, conico-globosa, umbilicata, nitida, tenui, concentrice 

 irregulariter costata, longitiidinaliter subtilissime striata : alba, 

 costelUs maculis rubris subdistantibus maculatis. 



Shell small, umbilicate, somewhat conically globose, rather thin, 

 shining, concentrically irregularly ribbed, longitudinally very finely 

 striated. Colour white ; transverse ribs spotted somewhat remotely 

 with red. 



Breadth 2, height \\ mill.

 Pacific Islands. B\ W. Harper Pease. 



Glathurella bicarinata. 



Shell turreted, white, decussated throughout with longitudinal 

 and transverse raised strise. Whorls six, the last ornamented by two 

 very prominent keels ; the interstices plane ; angtilated at the suture ; 

 Upper whorls carinate at their centre and angulated at the suture, 

 furnished with a single prominent keel ; su.tures deep, sinus in the 

 form of a narrow slit, terminating in a round aperture. Aperture 

 less than one-half the length of the shell ; canal short, broad, 

 slightly recurved.
