FISHES — WAI'I'IO. 



39 



Disc long and narrow, the snout much produced and acute, its 

 length 2-3 in that of the disc, interorbital width 5-8 in the 

 length of the snout. Rostral ridges convergent, meeting at 

 less than lialf the distance to the tip of the process and traceal)le 

 as a shallow groove on the upper surface. Nostrils lai-ge, the 

 distance between their outer angles less than half the snout, the 

 distance between their inner angles a little greater than the 

 width of each nostril. The anterior valve is produced as a fold 

 slightly towards tiie median line. Mouth bow-shaped, its width 

 twice that of the interorbital space, which is slightly concave, 

 no fimbriate appendage on the snout of the female. Vent equally 

 distant from the tip of the snout and the base of the caudal, or a 

 trifle nearer the latter. Dorsal fins similar. iSkin finely 

 shagreened. Two very small spines near the tip of the snout, 

 two conical spines in front and two behind each eye. Twenty- 

 one low spines on the dorsal line to the first fin and three or four 

 between the fins, two pairs on the shoulder girdle on each side of 

 the dorsal line and five rows of minute dermal elevations at each 

 outer angle of the disc. 



Colotir.- — Olive-yellow above, the fins grey with yellowish 

 margins. Bluish-grey to yellowish beneath, a dark patch towards 

 the tip of the snout extending backwards along the rostral process. 

 Length of specimen described, 555 mm. ; width nearly three 

 times in the total length \ tail rather more than twice ; snout to 

 the mouth 4-6 times in the same.

Although very common in Port Jackson, thence southward to 

 Tasmania and South Australia, it does not appear that observa- 

 tions have been recorded as to the northern range of the species, 

 a remark applicable also to many other forms. We took it at 

 the northern limit of our operations, namely, in the Manning 

 Bight, south of Crowdy Head (Station 27). Vertically it is found 

 from a few fathoms in the harbour to at least 59 fathoms, at 

 which depth we obtained it.
