A lamprey taken by Steller iu the liolschaya Eiver, Kamchatka, has not 

 been recorded by subsequent writers. It is reported by Steller as 13^ 

 inches in length;" the head i of an inch; mouth long, with 2 teeth above, 

 6 below dorsals 2. Color shining brassy, dark above; sides with dusky 

 serpentine lines. A figure published by Tilesius shows the upper teeth as 

 bifid, and 9 teeth below. 



Pallas describes specimens from the sea at Petropaulski as 7 inches long, 

 not marbled nor variegated. The species of Steller is probably an E„tos- 

 phenua. That of Pallas may be the same, or it may be a Lampetra, allied 

 to or identical with L. aurea.

 perhaps of P. marinus.
