24 THE VOYAGE OF H.M.S. CHALLENGER. 



A specimen 7-g inches long was found dead and floating on the surface of the water 

 near Stewart IsLand ; a second of the same length was caught in Otago Harbour, 

 September 6, 1884 ; and a third smaller one since that date.

This is probably the same species as the preceding, but described as having thirteen 

 abdominal scutes. The scales of the lateral line are said to be about fifty in number, 

 but as they are much larger than the other scales, no inference can be drawn from this 

 statement as to the distinctness of the two species. This species was described from a 

 .specimen, 9^ inches long, obtained at the mouth of the estuaiy of the Derwent.

The height of the body is contained twice and one-third in the total length, without 

 caudal ; the length of the head twice and one-half. Bones of the head sculptured in the 

 same fashion as in the other species of the genus. Eye rather larger than one-third 

 the length of the head. Suprascapulary spine smaller and shorter than that of the 

 prseoperculum. Scales thin, but wath their surface studded with minute spine.s. 

 Abdominal scutes nine. Spines of the fins rather strong ; also the rudimentary outer 

 rays of the caudal fin are modified into spines ; the dorsal spines increase in length 

 posteriorly, the length of the last being one-half of that of the head. Pectoral 

 extending to the middle of the anal fin, ventral to the vent. Silvery, tips of the caudal 

 lobes and top of the dorsal fin black. 



Two specimens were collected by the Expedition ; one, 3 J inches long, on the east 

 coast of New Zealand, at Station 166; depth, 275 fathoms. 



The specimen described by Dr. Hector was only 27 inches long, and obtained of!" 

 Cape Farewell in 400 fathoms.

 This species differ.^ from the Antarctic in having the bones of the head more 

 solid, narrower muciferous channels, a smaller eye, and the spinous dorsal fin
