FISHES. MCCULLOCH. 21t 



fourth longest and reaching backward beyond the second 

 anal ray; the broad membrane which usually connects 

 the inner ray to the middle of the pectoral base in 

 typical species of Callionymus is almost entirely wanting, 

 being traceable at the base of the ray only. Caudal 

 elongate, its upper and lower rays simple, the others 

 bifurcate. 



Colour-marking. Almost colourless after preserva* 

 tion in formalin, with traces of a few brown markings 

 on the upper half of the body, dorsal fins, and bases of 

 the pectorals and caudal, disposed as is shown iu the 

 accompanying figure. When first received, the head and 

 body were rose-pink with orange spots and bars ; the most 

 striking of these was one below the postero-inferior angle 

 of the eye, a saddle-shaped mark across the middle of 

 the back with a round spot before it, and several small 

 spots on the caudal peduncle. A yellowish-brown spot 

 on the upper base of the pectoral; the rest of the fin 

 rose-pink. Membrane of the first dorsal orange, the 

 spines white. A blackish-brown spot behind the first 

 spine, a similar one on the second spine but lower than 

 the first, and traces of others behind the third and fourth 

 spines. The second dorsal was marked with broad 

 oblique bars alternately orange and white, the orange 

 ones partly corresponding with the rays. Blackish bars 

 descended obliquely backward and downward from the 

 tips of each ray. Caudal rays white; the membrane 

 orange above, white below. Anal rose-pink. Ventrals 

 white. 



Described from a unique example, 123 mm. long. 



Affinities. This species is very close to CaUiouynms 

 pliasis Gtinther, from which it differs chiefly in its 

 delicate coloration. Two small specimens of that 

 species in the "Endeavour" collection have definite mark- 

 ings as figured by Gtinther, whereas those of C. apricus 

 are scarcely traceable on the body, being distinct only 

 on the dorsal fins. The dorsal spines of C. apricus are 

 longer than those of C, phasis, and the pectoral fins have 

 twenty-three instead of twenty rays, but in all other 

 structural characters the two species appear quite 

 similar. 



Locality. Great Australian Bight, south from 

 Eucla, 350-450 fathoms; 14th May, 1913.
