strong villiform teeth, the patches increasing in size backwards ; 

 the gill arches are also provided with teeth anteriorly. Large 

 patches of similar teeth occur in the back of the throat. Gill- 

 rakers long and flattened, denticulated along their inner edges ; 

 there are thirteen along the lower limb of each arch. Gill- 

 membranes free from the isthmus. 



Dorsal spines increasing regularly in length to the last, which 

 is much shorter than the anterior rays; all are rough with 

 coarse stria?. The soft dorsal is more than twice a« long as the 

 spinous portion, and its rays decrease evenly backwards. The 

 anal is similar in form to the dorsal, but it is considerably 

 shorter than the soft portion of that fin. Pectorals rather long 

 and narrow, l|-lf in the length of the head, and not quite 

 reaching the verticle of the vent; its margin is more or less 

 rounded. The ventrals reach from half to two thirds of their 

 distance from the vent ; the spine is broad and striated. Caudal 

 forked, with six striated spines on either side which are quite 

 distinct from the rays. 



Colour. — Yellowish white in formalin ; when first received all 

 the fins had traces of deep rose pink. 



Described from eleven specimens, 350-525 mm. long. They 

 were trawled in the Great Australian Bight. They possibly 

 represent the adult form of the smaller ones which I have 

 identified as a variety of H. mediterraneus, but differ so greatly 

 from them that, in the absence of intermediate examples, they 

 are best regarded as distinct.

Two specimens, 200-215 mm. long, from Western Australia, 

 between Cape Naturaliste and Geraldtou, do not differ from 

 others in the Australian Museum from Cape York, Queensland, 

 and China. Macleay and Klunzinger have recorded the species 

 from Port Darwin.
