108 NATURAL HISTORY OF ARCTIC AMERICA. 



coast Coitus scorpius and Qasterosteus pungitius sub-species brachypoda. 

 Many of the others are extremely rare in collections. 



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

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

 with some of the rarest of northern forms. 



Family, PLEUEONECTID^E. 



1. Pleuronectes Pranklinii Giinther. 



Pleuronectes FranUimi GUNTIL, Cat. Fish. Brit.Mus., iv, 1862, p. 442. 

 Pleuronectes (Rhombus) glacialis RICH., F. B. A., iii, 1836, p. 258. 

 Platcssa glacialis RICH., Voy. Herald, Fishes, 1854, p. 166, pi. xxxii. 



Eichardson records the species from Bathurst's Inlet (67 40' E"., 109 

 W.) 5 Dr. Giinther has Arctic American specimens from Dr. Eae and the 

 Haslar collection. Judging from the descriptions given, by Eichardsou 

 and Giinther, Pleuronectes Frariklinii is very closely related to P. ylaber 

 (Storer) Gill. 



2. Hippoglossus vulgaris Fleming. 



Halibut KUMLIEN, in lit. Feb. 16, 1879. 



Mr. Kumlien writes 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 was not Hippoglossus vulgaris , but Platysomatichthys 

 Mppoglossoides (=Reinliardtius Mppoglossoides (Walb.) Gill). 



Family, GADID^. 



3. Boreogadus saida (Lepech.) Bean. 



Gadus fabricii RICH., Faun. Bor. Amer., 1836, p. 245: GUNTHER, Cat. Fishes 



Brit. Mus., iv, 1862, p. 336. 



Boreoyadus polaris GILL ; Cat. Fishes E. Coast N. A., 1873, p. 17. 

 21746. (310.) Annanactook, Cumberland Gulf, A. L. Kumlien. D. 14, 18, 18. A. 

 21,19. P. 17. V.6. Leugth 250 millimetres. 



The inequality of the caudal lobes mentioned by Gill* is evident in 

 this example; the length of the upper lobe, measured from the origin of 

 the middle caudal rays, is 31 millimetres, of the lower lobe 27. The 

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

 rays, instead of pursuing the horizontal of the median line of the body, 

 are slightly raised, giving the fin a peculiar shape, which may perhaps 

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