370 MR. C. TATE REGAN ON 



ones truncated, the lateral ones obtusely tricuspid; palate toothless ; 

 maxillary extending to below nostrils. Depth of prteorbital f 

 diameter of eye. Gill- membranes broadly united, forming a fold 

 across isthmus. Dorsal XVI 12, scaly at the base ; spines stout, 

 subequal from the fifth to the last, which is g the length of head, 

 and a little shorter than the anterior soft rays. Anal III 10 ; 

 second and third spines subequal, ^ length of head; second or 

 third soft rays ^ as long as head. Caudal slightly emarginate. 

 Pectoral as long as head. Scales ciliated, 78 in a longitudinal 

 series, 12 or 13 between sheath at base of anterior dorsal spines 

 and lateral line. Dark greyish, with traces of darker spots and 

 markings. 



The above description from a specimen of 270 mm. A young 

 example, 43 mm. in total length, has the same number of scales 

 and fin-rays, but all the teeth are tricuspid, and the markings 

 obscurely indicated in the adult take the form of 7 dark cross- 

 bars and scattered spots on the body, and longitudinal bands on 

 the dorsal fin. The nearest ally of this species appears to be 

 Tephrceojys richardsonii, which ranges from New South Wales to 

 "Western Australia.
