THE FUR SEALS OF THE PEIBILOF ISLANDS. 



dorsals and the caudal dusky And edged with white; the pectorals are uniform dusky; 

 theyentrals but slightly dusted with black; the anals have a few punctulations at 

 their anterior ends; the peritoneum is pale. 



We have compared the skeleton of this with the skeleton of Microgadus proximus 

 (San Francisco) and fl^nd but very little difference in the skulls. There is no differ- 

 ence in the character of the neural spines of the vertebrae, but there is a difference in 

 the character of the transverse processes. In M. proximus they are flattish and plate- 

 like, while in E. navaga they are club shaped, narrow where they leave the centcum, 

 but expanding into a round, hollow bulb at the distal end. 



We obtained this fish only at Port Clarence, where it was abundant, the natives 

 catching great numbers of them with their crude hooks and lines. According to 

 Turner, " the Eskimos assert that these fish spawn in February among the pebbles at 

 the bottom of the deeper portion of the bay." 



32. Gadus macrocephalus Tilesius. 



We found this fish at Chignik Bay, where it is abundant. We preserved five 

 young specimens, whose fin rays are as follows : 



33. Atherestbes stomias (Jordan and Gilbert). 



Quite common at Chignik Bay, where we obtained a large specimen in 18 fathoms 

 of water. 



34. Hippoglossus hippoglossus (Linnseus). 



Obtained one specimen at Chignik Bay, where it is abundant. 



35. Lepidopsetta bilineata (Ayres). 



We found this fish quite common along sandy beaches in Chignik Bay. They 

 are in no way different from specimens of the same species from Puget Sound. 



36. Fleuronectes quadrituberculatus Pallas. 



Two specimens of this species were taken at Grautley Harbor, where it was not 

 rare. It appears to be common at Chignik Bay, where we obtained one specimen.
