2. E. tpieineta, sp. nov. Pi. iv., fig. 4. 



Shell small, elongately conical, pellucid-white ; apex hetero- 

 strophe. Spire-whorls six, somewhat convex, the anterior whorl 

 margining the suture, sculptured by three engraved spiral lines, 

 one median and one near to each suture. Last whorl regularly 

 convex and moderately attenuated at the base. Aperture pyri- 

 form ; outer lip straight and thin ; columella arched, there is no 

 indication of a plait or tooth. 



Length, 5-5; breadth, 1-75 mm. 



Has somewhat the aspect of Syrnola jucunda, but apart from 

 the different generic characters, the shell is narrower and the 

 last whorl proportionately much longer. 



Localities. — Streaky and Fowler Bays, in shell-sand (R.T.). 



Genus Odontostomia, 

 1. Odontostomia (Syrnola) infpasuleata, sp. nov. Pi. iv., fig. 5. 



Shell narrow-lanceolate, about four times as long as wide, 

 shining, white, feebly striated in an axial direction. Apex 

 heterostrophe. Spire-whorls nine, flat, suture linear. Body- 

 whorl imperforate, subangulate at the periphery, below which are 

 about six revolving incised lines, the posterior one a little in front 

 of the posterior angle of the aperture. Aperture narrow-oval ; 

 columella-plait very prominent, in front of which the inner lip is 

 effusively expanded, and its margin reflected ; outer lip not 

 ribbed within. 



A specimen in Dr. Verco's collection has two sulci on the last 

 whorl above the periphery, one of which is continued submedially 

 on the spire-whorls. 



Length, 11 ; breadth, 3 "5 mm. 



Localities. — Holdfast Bay, St. Vincent Gulf, and 

 Wauraultie, Spencer Gulf, in shell-sand (B.T.). 

 Dredged off Rapid Head in 10 to 12 fathoms by 

 Dr. Verco. 



Affinities. — This new species is conspicuous by its 

 elongate-oval aperture, effuse at the front and the 

 sulci on the base of the body-whorl. It seems to 

 have no near ally among figured species, though 

 *S'. gracillima is a micromorph of it as regards 

 shape. 



Supplemental Note. — The annexed figure of 

 0. {Syrnola) Jonesiana, described in Part I of the 

 present volume, p. 70, is added for comparison with 

 the present species, between which there are great 

 resemblances.
