threads may arise ; a funicular rib on the anterior end of the shell encloses 

 a small false umbilicus ; the fasciole is broad, and is appressed to the 

 suture ; it is smooth save for crescentic growth lines. Aperture : — The 

 sinus is wide and V-shaped ; the outer lip is arched forwards, and the 

 free sharp edge is bent inwards a little towards the aperture ; opposite 

 the base of the canal is a stromboid inflection ; canal short, wide, and 

 sharply recurved ; columella overspread with a thick callus rising in a low 

 tubercle o{)posite the sinus. Length 46 mm., breadth 15 mm. 



This is a member of the group of Drillla flavidula. In size and 

 contour it resembles the Japanese Drillia jeffreysi Smith,*© but the Queens- 

 land shell is narrower, the nodular ribs not so prominent, and the spirals 

 are finer and closer. 



Hub. Queensland : — 10 fathoms, off Mapoon (type, self) ; Keppel

Shell rather thin, elongate-fusiform, turreted. Whorls ten. Sutures 

 channeled. Colour pale buff, witli rust dots between the peripheral 

 nodules, and irregular rust streaks and splashes elsewhere. Sculpture: — 

 On the summit oF each whorl is a collar of two strong spirals ; besides, the 

 whole surface is ovei'-iun with fine, close, flat-topped s]>iral threads, 

 amounting to about fifty-five on the last whorl ; along the shoulder runs 

 a row of upright tubercles, twice as high as broad, and moi-e than their 

 own breadth apart, — twenty-two on the penultimate whorl, most distinct 

 on the earlier whorls, and gradually fading till they almost disappear on
