FISHES. MCCULLOCH. 179 



is covered with a row of scales. Another scaly ridge 

 extends forward from the ocular margin, above and 

 around the nasal region. The occiput and interorbital 

 regions are without prominent ridges. The lateral ridge 

 from the rostral tubercle to the preopercular angle is 

 armed with thickened spinate scales. Nostrils close 

 together, a little before the eye; the anterior is circular, 

 and the posterior forms a curved slit. Maxillary reach- 

 ing backward to below the hinder third of the eye. A 

 broad band of villiform teeth in each jaw. Mental barbel 

 almost half as long as the eye. Preopercular angle form- 

 ing an obtuse point ; suboperculum produced into a sharp 

 angle. 



Body scales with many subparallel rows of spinules 

 on their exposed surfaces; these are of equal size and 

 number as many as sixteen on some scales below the 

 first dorsal fin. The median scales before the dorsal fin 

 do not form a crest as is often present in C. fasciatus. 

 The vent is situated a short distance before the anal 

 fin; a median naked sulcus is present between it and the 

 ventral fins. Lateral line forming a low curve anteriorly. 



Anterior dorsal spine minute, the second is smooth 

 and its filamentous tip projects beyond the first ray; 

 when adpressed it reaches the origin of the second dorsal. 

 The interspace between the two dorsals is twice as long 

 as the base of the first. The rays of the second dorsal 

 are very low anteriorly, but increase in length backward. 

 First ventral ray filamentous, reaching the origin of the 

 anal. The tail is incomplete in the type, but in another 

 specimen, 275 mm. long, the head (56 mm.) is 4-9 in the 

 total length. 



Colour. Head and body uniform grey. A small 

 black spot on the lower pectoral rays forms a contrast 

 with the light coloured base of that tin which is sharply 

 defined in a dark bluish area. The filamentous ventral 

 ray is whitish, the others bluish-black. 



Described and figured from a specimen, 230 mm. long, 

 from 150 fathoms, east of Sydney. 



Affinities. This species is very similar to C. fasciatus 

 but differs consistently in having a somewhat smaller eye, 

 which is subequal to instead of longer than the post- 

 orbital portion of the head, and in having scales on the
