40 RECORDS OP THE AUSTRALIAN MUSEUM, 



connected to the base of the second by membrane. The dorsal 

 rays equidistant. Caudal peduncle long and slender, the mem- 

 brane from the last dorsal ray reaching from half to two-thirds 

 along its length. A branched tentacle on the snout, and a long 

 simple one over the e} T e. Snout sub-conical. Vertebrae 14 + 30. 



This is the commonest species of the genus in New South 

 Wales, and is taken in the sea-grass Zostera, by net fishermen. 

 Its general colour is green, with darker bands and silvery 

 markings.

In the Museum collection there is a specimen labelled 

 " Cristiceps splendens, Cast., Adelaide," which agrees well with 

 the description of that species in all but having the interorbital 

 space much less than the vertical diameter of the eye. Other 

 specimens from South Australia, and Fremantle, Western Aus- 

 tralia, and one from Jervis Bay, New South Wales, have the 

 fin formulae as follows : — 



D. iii., xxvi.-xxviii.. 6-7. A. ii.; 22-24. V. 3. 



Beyond the reduced number of rays in the anal fin, I am 

 unable to find any differences between these and C. australis, C. 

 and V. 



(a) 1 Adelaide, South Australia. 



(b) 3 South Australia. 



(c) 2 Fremantle, Western Australia. 



(d) 1 Jervis Bay, New South Wales.
