NORTHERN ZOOLOGY. 



directed backwards. These spines are too minute to be seen distinctly by the naked eye, but 

 a little fold of skin, raised by each of them, produces a roughness which is very visible; they 

 resist the finger only when it is drawn against their points. The lateral line, formed by a 

 furrow, interrupted by about forty-four contractions, is very conspicuous.

The ventrals are situated posterior to the three under rays of the pectorals and anterior to 

 the upper ones. The pectorals are obliquely obovate. The first dorsal, commencing oppo- 

 site the upper pectoral ray and supra-scapular point, is lower than the second one and not 

 half its length ; its spines are slender, but scarcely flexible, and its membrane is attached to 

 the lower third of the first ray of the second dorsal ; the sixth and seventh spines are the 

 longest. The second dorsal commences opposite the anus, and extends a little farther back 

 than the anal. 



" Colours, generally, greyish-white ; top of the head, back, and sides studded with small 

 clove-brown spots, in some places confluent and forming patches. Pectorals, dorsals, and 

 caudal marked with transverse rows of clove-brown spots. Under parts whitish with minute 

 specks." (Gairdner.) 



Intestines. — The stomach is a roundish muscular bag, having one-third of its cavity be- 

 neath the pylorus. There are five cseca, four of them slender, cylindrical, and of unequal 

 lengths, the fifth a short oval bag.
