 lateral line extends to the caudal fin, or is interrupted. One 

 dorsal fin with the spinous portion as well developed as the

 thoracic, with one spine and five soft rays. Palate without 

 teeth ; only one lower pharyngeal bone without median

 D. i§ ; A. i; ; L. Lat. 58-60 ; L. j\. 

 The height of the body is contained five times and one-fifth 

 in the total length. Caudal fin somewhat lyre-shaped owing 

 to the upper and lower filamentous rays being produced two 

 or three inches beyond the middle series. Like 0. cyanomelas 

 (Richards.) of the Australian coast, from which perhaps it is 

 doubtfully separable, there is a bluish streak along the upper 

 and lower margins of caudal fin ; there are bluish patches 

 on the snout, and the general colour of the body is a dull 

 greenish blue. Caught by Mr. John Brown in *the neigh- 

 bourhood of Table Cape. This is i\\Q first representative Of 

 the genus recorded from Tasmanian waters. Its nearest 

 ally in Tasmania is the genus Odax, of which " The 

 Stranger" is a member.
