fuscus, was obtained, D. carponemios was gathered in considerable 

 quantities. Hitherto ahnost unknown, excepting from adult 

 examples, we were fortunate in netting young ones. Most of 

 them were collected in deep water, say 45 to 75 fathoms, and 

 none were got in less than 23 fathoms. Beyond enabling us to 

 note the fact, our observations were not sufficiently extensive to 

 empower us to form any definite opinion as to the breeding habits 

 of this species, a subject at present quite unknown. Had opera- 

 tions been continued further southward we should pi'obabl}" have 

 met with greater success with this species, as it is peculiarly a 

 southern form, known from Victoria, South Australia, and New 

 Zealand. Station 21, in the Newcastle Bight, is, I believe, the 

 most northern point whence it has so far been recoi'ded.

This species is closely allied to, if not identical with //. 

 hyiJsilepis, Giinth.,*' the description of which, however, is insuffi- 

 cient for comparative purposes. It is to be noticed that our 

 specimen, and also all others caught off the coast, have immacu- 

 late fins, and in this particular differ from the description of 

 H. hypsilepis. Each body scale of our example bears at its basal 

 portion a faint purple mark ; an appearance of longitudinal lines 

 is thus produced. 



The single representative was secured off Cape Hawke, in 35 

 fathoms, where the trawl encountered rock the moment it touched 

 bottom.
