THETIS SCIENTIFIC RESULTS. 



with a two-whorled protoconch. Surface entirely microscopically 

 granulated. Behind the aperture is a gradually swollen varix, 

 in which the rounded sinus is obliquely excavated. The entrance 

 of the sinus is narrowed Vjy 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 50-5 2 fathoms; and off the Manning 

 River in 22 fathoms. Also collected previously 

 off Cabbage Tree Island, Port Stephens, in 24 

 fathoms.

 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 

 Avhorl 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 vvhich it may be distinguished 

 by having no sinus, a denser ornament, 

 and by being smaller and proportionately 

 broader. D. hayesiana is compared by its 

 author to ClatJuirella reticosa, Ad. & Angas,t 

 an alleged Australian species, probably 

 founded on an imported British specimen 

 of Clallairella purpuren , Montagu.
