FISHES. — MCCULLOCH. 



159 



Knur young examples, 325-420 mm. long, differ from 

 G. microstomas, Regan, in having smaller eyes, which are about 

 as wide as the interorbital space, and in colour-marking. The 

 whole fish is much darker, owing to the brown markings being 

 broader than the interspaces between them, and the dorsal and 

 anal fins have only narrow white margins. They are well repre- 

 sented by McCoy's figure, quoted above. 



A very large specimen, 1125 mm. long, differs from the smaller 

 ones in its proportions, the tail being a little shorter, instead of 

 somewhat longer than the head and body. The eye is propor- 

 tionately smaller, and the interorbital space is much wider ; 

 they vary in the five specimens as follows: — Eye 6.9-9.6 in the 

 head, bony interorbital width 7.5-8.6 in the same.

 specimens.

Genypterus microstomus, Regan.

 xi., L908, p. 599. 



In eight specimens, 275-405 mm. long, the eye is 5.4-6.8 in the 

 length of the head ; the bony interorbital width is 9.1-10.9 in 

 the same, and not more than two-thirds as wide as the eye. The 

 colour-marking consists of more or less distinct brown, wavy 

 bands, which are about as broad as the interspaces between them : 

 a very prominent black band is present on the posterior portions 

 of the dorsal and anal fins, which also have broad white 

 margins. 



The lighter colour-marking, broad white margins of the dorsal 

 and anal tins, the larger eye, and the narrower interorbital space 

 distinguish this species from G. blacodes. Regan noted that the 

 maxillary did not reach beyond the hinder margin of the eye as 

 in all the other species of GenypteYus, but this is not a reliable 

 character. In five of my eight it is as he decribes it, in one the 

 maxillary reaches a little beyond, and in two well beyond the 

 eye ; on the other hand, in one of my specimens of G. blacode* 

 it ends below the hinder ocular margin.
