Dentalium lubricatum, Sowerby, Thes. Conch., ii., 1860, p. 97, 

 pi. ccv., f, 56. 



Stations 13, 49. 



Several specimens were obtained from 63-75 fathoms off Port 

 Kembla, of which the largest is 32 mm. long ; and from 41-50 

 fathoms off Cape Three Points. 



DENTALIUM VIRGULA, sp. nov. 



(Fig. 62.) 



Stations 13, 37, 49, 57. 



Shell small, a little curved, slightly taper-

 tube, 0*2 mm. 



This species belongs to the subgenus E2)isi- 

 phon of Pilsbry and Sharp.* 



Numerous examples were taken in 63-75 

 fathoms off Port Kembla ; in 41-50 fathoms 

 off Cape Three Points ; in 54-59 fathoms off 

 Fig. 62. Wata Mooli ; and in 50-52 fathoms off 



Botany Bay.

This species also extends to New Zealand. Mr. A. Hamilton,

 off Anchor Island, Dusky Sound, N.Z.
