Loc— Great Australian Bight, 129°28'E., 350-450 fathoms; 

 14th May, 1913. 



Genus Neocyttus, Gilchrist. 



Neocyttus, Gilchrist, Marine Invest. S. Afr., iv., 1907, p. 153 

 (N. rhomboidalis, Gilchrist.) 



Body compressed and elevated, covered with rather small 

 ctenoid scales, which are mostly imbricate ; on the nape, head, 

 and ventral profile their edges are turned outwards and strongly 

 spinate, making these parts very rough. They do not bear any 

 central tubercles, nor are there any enlarged flat scales on the 

 sides as in Allocyttus and Cyttosoma. 



Jaws very protractile, the intermaxillary processes received 

 into a broad, oblong cavity extending backwards to above the 

 middle of the orbits. Superficial bones of the head with coarse 

 granules and ridges ; those of the operculum forming a radiating 

 series. Preorbital of moderate width. Small teeth in the jaws 

 and on the vomer ; palatines and tongue toothless. A single 

 dorsal tin with seven or eight strong spines and about thirty-four 

 rays. Anal with three or four spines, and about thirty-one 

 rays. Ventral with one spine and six rays. Seven branchios- 

 tegals.
