PISHES. MCCULLOCH. 205 



Jackson. All have the first dorsal spine shorter than the 

 second, and the black spot on the dorsal fin extends over 

 the membrane between the second and fourth spines. 

 These two features appear to be the only characters by 

 which C. calcaratus can be separated from C. valencien- 

 nesii, in which species the first spine is distinctly longer 

 than the second, and the black spot is restricted to the 

 space between the third and fourth spines. 



Localities. C. calcaratus has been recorded hitherto 

 only from New South Wales and Houtman's Abrolhos, 

 Western Australia. Ten of the "Endeavour 11 specimens 

 were trawled in Queensland waters. 



Mouth of Wide Bay, Queensland. 

 Northern New South Wales. 



CALLIONYMUS MACDONALDI Oc/ilby. 

 (Plate liv, fig. 1.) 



CaUionyinus nuicdonaldl Ogilby, Ann. Qld. Mus. No. 10, 

 1911, p. 56, pi. vi, fig. 2. 



D.iv/9; A.9; P.I 9; V.i/5; 0.10. 



Depth before the dorsal fin (11 mm.) 8-9, breadth 

 before the pectorals (20) 4-9, and length of head (32) 

 3-06 in the length to the hypural joint (98). Eye (7) 

 shorter than the snout (8) and 4-5 in the head. Inter- 

 orbital space (1) 7-0 in the eye. First dorsal spine (8-5) 

 3-7, last dorsal ray (14-5) 2-2, and last anal ray (13) 2-4 

 in the head. Caudal fin (27) 1-1 in the head. 



Head rugose above, with reticulating bony ridges 

 radiating from centres and enclosing shallow circular 

 pits; a patch on each side of the occiput is largest and 

 two smaller ones are present immediately behind the 

 orbital ridges and iuterorbital groove, and three on the 

 posterior part of the cranium. Snout obtusely rounded 

 when viewed from above ; the width of the head at the 

 bases of the preopercular spines is almost equal to the 

 distance between the gill-openings and the tip of the 

 snout. Upper lip projecting beyond the preorbital bones 

 when the mouth is closed, and well beyond the lower jaw. 

 Maxillary reaching backward to the vertical of the 

 nostril. Interorbital space narrow and grooved. Pre- 

 opercular spine curved upward at the distal extremity.
