108 NATURAL HISTORY OF ARCTIC AMERICA. 



coast — Cottus scorpius and Gasterostcus pungitius sub-species br((cliijiK»h(. 

 Many of the others are extremely rare in collections. 



Lieutenant Miutzer's collection also, though small in the number of 

 species, is ridi in interest, and has greatly extended our acquaintance 

 witli some of the rarest of northern forms. 



Family, PLEURONECTID^.

 Uaslar collection. Judging from the descriptions given by Richardson 

 and Giinther, Plciiroucctcs Franldinii is very closely related to P. (jlahcr 

 (Storer) Gill. 



2. Hippoglossus vulgaris Fleming.

Mr. Kimdien wiites me, that " in February a large halibut was caught 

 in a seal breathing-hole by an Eskimo, but it was something entirely un- 

 known to them." 



It may be that this -wnsnot IIi2)2)oglossus vulgaris, but Flatysomatichthya

The ine(piabty of the caudal lobes mentioned by Gill* is exideiit iu 

 this example; the length of Iho upi)er lobe, measured fioui the oii-iii of 

 the middle caudal rays, is 31 millimetres, of the lower lobe L'7. The 

 outline of the lower lobo is decidedly convex below. The middle caudal 

 rays, in.stead of pursuing the horizontal of the median line of the body, 

 are slightly raised, gi\ iiig tlic tin ;i ])eriili;ir shape, wliirli may ])erhaps 

 be due to outside circumstances, or may bo characteristic of the adult.
