CALLIONYMUS CALAUROPOMUS Richardson. 



Callioiiymus calauropomus Richardson, Ichth. Erebus 

 and Terror, 1844, pp. iv and 10, pi. vii, figs. 4-5.

Thirteen specimens, 60-360 mm. long, agree well with 

 McCoy's figures, and exhibit considerable variation. The 

 caudal rays are shorter than the head in some speci- 

 mens, and more than twice its length in others. The 

 colour-marking varies in intensity, but is of the same 

 pattern as is illustrated by McCoy. The armature of 

 the preopercular spine, which has only two recurved 

 hooks at its tip and lacks a basal antrorse barb, and the 

 bifurcation of the dorsal rays afford excellent specific 

 characters, being constant in all specimens examined. 



Localities. East of Flinders Island, Bass Strait. 



Off Marsden Point, Kangaroo Island, South Aus- 

 tralia ; 19th August, 1909. 



Doubtful Island Bay, south-western Australia, 20- 

 25 fathoms; 30th November, 1911. 



CALLIONYMUS APRICUS sp. nov. 

 (Plate liv, fig. 2.) 



D.iv/8;- A.7; P.23; V.i/5; C.10. 



Depth at origin of dorsal fin (13 mm.) 6-4, breadth 

 before the pectorals (15) 5-6, and length of head (27) 3-1 

 in the length to the hypural joint (84). Eye (9-5) much 

 longer than the snout (6) and 2-8 in the head. Inter- 

 orbital space (1) very narrow. First dorsal spine (31) 

 2-7, median dorsal rays (24) 3-5, and median caudal rays 

 (37) 2-2 in the length of the hypural joint. 



Head and body subcylindrical, and not much broader 

 than deep; the width of the head between the bases of 

 the preopercular spines is only a trifle greater than the 

 distance between the tip of the snout and the hinder 

 margin of the eye. Upper surface of head with a loose 

 transparent epidermis raised high above the bones of 

 the cranium; the occiput has a low conical prominence 

 on each side with very fine reticulating ridges radiating
