THETIS SCIENTIFIC RESULTS. 



with a two-whorled protoconch. Surface entirely mici'oscopically 

 granulated. Behind the aperture is a gradually swollen varix, 

 in which the rounded sinus is obliquely excavated. The entrance 

 of the sinus is narrowed by a thick parietal pad of 

 callus and the thin incurved corner of the outer 

 lip. On the columella is spread a thick sheet of 

 callus. Length, 9 mm.; breadth, 3-75 mm. 



A few specimens from off Port Kembla in 

 63-75 fathoms; off Cape Three Points in 41-50 

 fathoms; off Wata Mooli in 54-59 fathoms; off 

 Botany Bay in 50-52 fathoms; and off theManning 

 River in 22 fathoms. Also collected previously 

 off Cabbage Tree Island, Port Stephens, in 24 

 ' '^ fathoms.

DAPHNELLA VESTALIS, sp. nov, 



(Fig. 105.) 



Stations 13, 37. 



Shell ovate, rather solid, angled at the shoulder, constricted at 

 the base. Colour white. Whorls five, plus 

 a two-whorled protoconch. Sculpture : 

 rounded spiral cords, the longitudinal series 

 amounting to about twenty on the last 

 whorl and eight on the penultimate, crossing 

 and knotting a spiral series amounting to 

 about thirty-seven on the penultimate; the 

 longitudinals vanish at the base and are 

 effaced behind the aperture. Suture 

 channelled. Protoconch smooth. Aperture 

 wide, lip simple and without sinus. Length, 

 8 mm.; breadth, 3-75 mm. 



This species is nearest to D. hayesiana, 

 Angas,* from which it may be distinguished 

 by having no sinus, a denser ornament, 

 and by being smaller and proportionately 

 broader. D. hayesiaiia is compared by its 

 author to Clathurella relicosa^ Ad. & Angas,! 

 an alleged Australian species, probably 

 founded on an imported British specimen 

 of Clatkarella jmr'purea, Montagu.
