Tlie lower jaw is longer than the upper. A broad band of 

 villiform teeth in l)oth jaws, the innermost ones being the largest. 

 A A'ery long band on each palatine, and a large patch on the 

 v(jiner whicli sends backwards two other parallel rows. All the 

 iiuier teeth are larger tlian those of the jaws. The maxillary 

 reaches almost to the fx-ont margin of the orbit. Gill membranes 

 united to the isthmus, without a fi'ee fold, and separated by a 

 space equal to half the interorbital width. 



Above the lateral series of j^lates and posterior to the first 

 dorsal fin, are some widely scattered, thin, cycloid scales, almost 

 entirely imbedded in the skin. On the caudal peduncle they are 

 more numerous, overlapping and smaller. The large lateral plates 

 are roughened by a number of minutely denticulated ridges radi- 

 ating from the large blade-like spines, which latter increase in 

 size backwards. The pores of the lateral line are placed below 

 the middle of these spines, and there are no smaller secondaiy spines. 

 The hinder edges of the plates are smooth and deeply cleft in the 

 middle. 



The spines of the first dorsal are slender, tlie second lieing the 

 longest, 1'38 in the snout (this fin is malformed in the lai'ger 

 specimen, the measurement being therefore taken from the smaller 

 one). The second doi'sal ray is the highest and more than once 

 and a half longer than the highest (7th) anal ray. The anal 

 commences beneath the 2nd or 3rd dorsal ray and terminates far 

 behind that fin. Caudal almost truncate, the upper rays a little 

 longer than the lower. The four lower pectoral rays are free 

 except for a low membrane at their extreme base. They are 

 thickened, and longer than the rays above them. The following 

 one or two rays may be also simple but are joined by membrane 

 to their tips. The venti-als are inserted well in advance of the 

 pectorals, the rays increasing in h^igth backwards. Both specimens 

 have a small anal papilla. 



Colours in life pinkish yellow above, white beneath. Doi'sals, 

 caudal and pectorals pinkish, the latter finely edged with white. 

 The vertical fins and tail with darker markings. 



I have pleasure in associating with this fish the name of 

 Professor VV. A. Haswell, the leader of the expedition. 



This species is closely allied to //. lilatoimrys, Jord. and Everm., 

 but appears to be distinguished by its different fin formula, the 

 character of the lateral plates, the lower pectoral rays being 

 divided to their base, and by the shape of the snout. 



Type 430 mm. long, from SOO fathoms, thirty-five miles east of 

 Port Jackson. One other specimen, 340 mm. long, taken with the 

 type.
