434 THE FUR SEALS OP THE PRIBILOF ISLANDS. 



Paul, other specimeus were obtained from tide idooIs and by hook and line fishing. 

 After the Albatross left St. Panl, Captain Moser and Dr. Stejneger, with the assistance 

 of Mr. N. B. Miller, photographer and preparator, made collections by dredge and 

 seine about Petropaulski, off Eobben Eeef, and among the Kurile Islands and Teso. 

 The collection thus obtained was especially valuable, as it includes numerous species 

 not seen since the time of Krascheninnikof and Pallas. A small collection of fishes, 

 mostly from Tareinsky Bay, Kamchatka, was received from Mr. Gerald E. H. Barrett 

 Hamilton, of the British commission.* A small collection was also made by the 

 Albatross under Dr. Jordan's direction in the Shelikof Straits, off Karluk, in 1897. 



On these various collections the present paper is based. For completeness sake 

 reference is made to all species of fishes thus far authentically recorded from Bering 

 Sea. As the synonymy of each of these species is given in Jordan and Evermann's 

 Fishes of Northern and Middle America, it is not repeated here. The new species 

 here described are also included in the latter work, the second part of which was 

 published October 3, 1898, the third, Nov. 26, 1898, both dates being prior to the 

 appearance of the present paper, which was, however, written first. 



Family PETROMYZONID^E. 



1. Lampetra aurea (Bean). 



Recorded only from the Yukon Eiver ; not seen by us. 



2. Entospbenus tridentatus (Gardiner). 



Taken by Dr. Gilbert at Unalaska ; common southward along the coast. Five 

 specimens were found by Mr. Lucas in the stomach of a fur seal from Bering Sea. 



3. Entosphenus camtschaticus (Tilesius). 



Tilesius and Pallas briefly describe a lamprey from Kamchatka. It has not been 

 recorded by later writers. It probably belongs to JSntosphenus, but this is not certain. 

 A larval lamprey obtained by Stejneger in the Paratunka Eiver, near Petropaulski, 

 Kamchatka, is apparently of some species of Entosphenus. It can not be distinguished 

 from the larva of E. tridentatus, though the adult may show peculiar characters. 



Family SQUALID^rE. 



4. Squalus sucklii (Girard). Dogfish. 



A single specimen of the dogfish was brought by Stejneger from Bering Island. 

 It is otherwise unknown from Bering Sea. The dried specimen referred to this species 

 by Mr. H. W. Elliott, found by Mr. William Palmer on Zoltoi Sands, St. Paul Island, 

 is a shriveled ray, Baja parmifera. The dogfish is said to occur about Kadiak, but 

 we did not find it there. The salmon shark, which is destructive to the salmon at 

 Karluk, is not the dogfish, but Lamna cornubica. 



Family SOMNIOSID^E. 



5. Somniosus microcephalus (Bloch). Sleeper shark. 



Not uncommon in Bering Sea; not seen by us. 



Family RAJID^E. 



6. Raja parmifera (Bean). 



Common in Bering Sea; found by us on the beaches of St. Paul; recorded by 

 Bean from St. Michael and Unalaska.
