110 "endeavour" BCIENTIFIC RESULTS. 



Luc*. — The " Endeavour" collection includes two from the 

 following localities. — 



Shoalhaven Bight, New South Wales. 42 fathoms. 

 Investigator Strait, South Australia. 



Family CrLETODONTHLE. 



Genus Vinculum, <jen, hoc. 



A Chsetodon with ten dorsal spines of which the middle ones 

 are the highest. Scales very small, seventy-five or more between 

 the operculum and the hypural. Second anal spine stronger, but 

 not longer than the third. 



This genus differs from Chcetodon in having very much smaller 

 scales and fewer dorsal spines. The small scales also separate 

 it from Microcanthus, and Hemitaurichthys, Bleeker, while the 

 first-named also has the third anal spine much shorter than the 

 second.

This species is well described by Richardson. The scales are 

 so small and irregular that I have been unable to satisfactorily 

 count the number between the operculum and the hypural, but 

 there are between seventy-five and ninety. 



Locs. — The " Endeavour " specimen is 250 mm. long, and was 

 obtained in Doubtful Island Ray, West Australia in 20-25 fathoms. 

 1 have examined two others, one of which is fi'om Albany, West 

 Australia, and the other is one of those recorded from Mordialloc, 

 Port Phillip by Kershaw. The last is the specimen figured.
