Head 3 ; depth 4|. D. IX or X, 17 ; A. 12 ; V. I, 3 ; lateral line 38. Body 

 stoutish, tail slender. Head moderate, not depressed; jaws short, the 

 maxillary reaching middle of the large eye; lower jaw included; top of 

 head concave between the 2 occipital ridges; these very low, with obtuse 

 tubercles instead of spines, these ending each in a small tentacle, which 

 is often obsolete; preopercular spines 3, short, the upper equal to eye; 

 the second about 4- as long, the lower directed downward; opercular 

 spine obscure; a short humeral and a short supraseapular spine; nasal 

 spines sharp; top of head with smooth skin. Skin nearly smooth, some- 

 times a few warts above lateral line. Isthmus narrow, the fold across 

 it very narrow; no trace of slit or pore behind last gill. Dorsal fins 

 slightly joined, the spines slender; pectorals reaching past front of 

 anal. Coloration, dark olive, finely mottled with paler; fins dusky, with 

 paler spots ; anal with 2 oblique dark bars ; a pale blotch at base of caudal. 

 Arctic regions of America ; Greenland and neighboring waters ; common 

 about Disco Bay, from which locality we have numerous specimens, 

 received from Prof. D'Arcy W. Thompson (Coll. Lohmann). (dnopTtiot,

 Cottus pachypus,* GUNTHER, Cat. Fish., n, 161, I860, Port Leopold. (Haslar Coll.) 



* Cottus pachypus, GUNTHER, is thus described : 



"D. IX, 16; A. 12 to 14. Two small spines above the snout, an abtuse one above each 

 orbit, and a pair of obtuse prominences on the occiput. The impression on the crown 

 becomes narrower posteriorly, and is nearly twice as long as broad. Three preopercular 

 spines, 2 of which are at the angle; the upper is the longest, its length being equal to the 

 diameter of the eye, but less than the width between the orbits. The height of the first 

 dorsal is somewhat more than the length of the maxillary bone; the ventral terminates at 

 a great distance from the vent, and the pectoral does not reach to the anal. Skin above 

 the lateral line with smooth warts. Brownish, spotted with darker (colors faded). Port 

 Leopold. 



"Description of the specimen: The greatest height of the body, in front of the dorsal, 

 is 4 in the total length ; its greatest width, behind the pectorals, 4 times. The tail tapers
