FISHES. MCCULLOCH. 127 



Upper eye slightly in advance of the lower. Maxillary ex- 

 tending backwards to behind the orbital margin ; lower lip with 

 a few small tubercles. Nostrils tubular, the anterior of 

 both sides with posterior lobes. Teeth in a band on the lower 

 side of each jaw. Gill-rakers of the first arch reduced to minute 

 tubercles. 



Dorsal commencing on the tip of the rostral hook, the anterior 

 rays free and simple. Left pectoral shorter than the right, the 

 the first ray very short, with a small fleshy tubercle at its tip. 

 Right ventral in a line with and joined to the anal, its anterior 

 rays somewhat like those of the dorsal. Middle caudal rays the 

 longest, the margin obtusely pointed. 



Colour. — Pinkish, with numerous small dark grey ocelli on the 

 head and body. Fins dotted with dark grey. 



Described from a single specimen 98 mm. long. 



A. macrolepis is most nearly allied to A. tudori, and it is with 

 hesitation that I venture to separate it from that species. It 

 differs in having such larger scales and rather more numerous 

 dorsal, anal, and ventral rays. The maxillary also reaches well 

 beyond the anterior orbital margin. 



Loc. — East coast of Flinders Island, Bass Strait, 40 fathoms. 



The following is a key to the species of Ammotretis. — 



a. Width more than half the length from the upper jaw to 

 the hypural. 



b. Rays of dorsal and anal tins scaly above. 



c. Pectorals of equal length ; right ventral with 7 



™J S rostratus. 



cc. Lower pectoral shorter than the upper ; veutrals with 

 10-12 rays. 



d. Maxillary uot reaching to orbital margin ; 1. lat 

 80-90 tudori. 



dd. Maxillary reaching beyond orbital margin ; 1. lat. 



66 macrolepis. 



bb. Dorsal and anal rays without scales above. 



e . Rostral hook long ; interorbital space wide ; body 



with large blotches nudipin n is . 



ee. Rostral hook small ; interorbital narrow ; body with 



spots forming lines guntheri . 



aa. Width less than half the same length elongatus.
