"ENDEAVOUK" SCIENTIFIC EESULTS. 



tion in having eighteen instead of sixteen anal rays.i The 

 last dorsal spine is minute and often rudimentary, while the 

 position of the base of the second spine is altered by the 

 development or otherwise of the hump on the back. 



FIG. S. 



In order to show the change with growth more clearly I 

 give a figure of the smallest specimen of the series for com- 

 parison with Waite's figure of the adult. It is 66 mm. long 

 and was trawled off Cape Three Points, New South Wales, 

 in 32-40 fathoms. 



As Centriscus scolopax, this species has been recorded from 

 Tasmania by Johnston, 2 and there is a specimen in the Aus- 

 tralian Museum collection from Ulverstone. The "Endea- 

 vour" trawled it at the following stations: — 



Twenty miles off Babel Island, Bass Strait, 68 fathoms. 



Off the east coast of Flinders Island, Bass Strait, 60 

 fathoms. 



Disaster Bay, New South Wales, 45 fathoms. 



Between Port Stephens and Sydney, New South Wales, 

 22-65 fathoms. 



Ogilby's specimen of M. gallinago came from the Tweed 

 River Heads at the northern boundary of New South W^ales.

Centriscops humerosus, Richardson.

1 Mr. J. D. Ogilby has very kindly compared "Tlietis" specimens with 

 his type and he informs me that he considers them to be identical. He 

 further notes that the latter has eighteen and not sixteen anal rays as 

 described, a mistake due to a printer's error.
