speckles which form irregular, ohlique liars: anal closely speckled, the marginal 

 ])ortion darker. 



Descrihed and figured from a single, somewhat damaged specimen, ^y mm. 

 long. It is allied to H. lucdiuiu Giinther (l), but differs in the form and com- 

 position of its fins. 



Loc. St. \'incent Gulf. South Australia. 



TRIANECTES gen. nov. 



fiody rather short and deep, covered with large ctenoid scales which extend 

 over the breast and abdomen : two lateral lines, the first formed of simple tubes and 

 parallel with the back, the second of incised scales along the middle of the tail: 

 head large, rounded, and naked, with numerous pores: eye large: mouth large, 

 the maxillary exposed, jaws subequal : upper angle of operculum forming a flat 

 s]iine. not rounded: teeth moderate, in a band in each jaw, the lower the larger; 

 a single curved row on the vomer, palatines toothless. Three dorsal fins, the 

 two anterior s])inous : ])ectoral with l)ifid rays in its upper half and simple ones 

 l)elo\v : ventrals jugular, with two simple rays. 



Type. T. biiccphaliis. sp. nov. 



This genus ditfers from Triptcryf/ioii not only in the very dififerent form of 

 the head, but also in lacking palatine teeth ; the uiiper angle of the operculum 

 also is spine-like, not rounded, and scales cover the breast and abdomen. It is 

 near Notocliiiiis (iill (3). but has the upper pectoral rays divided and more 

 numerous than in that genus.
