Distribution and density ( average number per 10 ni-) of Lepidopsetta bilineata in the Gulf 

 of Alaska and Bering Sea, 1972-1994. 



Etymology 



The specific name is derived from the Latin bilineata. 

 meaning "two hned", a reference to the bifurcate supra- 

 temporal branch of the lateral line. 



Comments 



Basing his work on an account first published in The 

 Pacific (Ayres, 1855a) and subsequently reprinted in the 

 Proceedings of the California Academy of Sciences (Ayres, 

 1855b), Ayres described his specimen of Platessa bilineata 

 at the California Academy of Natural Sciences (CAS) in 

 1855. The specimen has not been located at CAS"* (where it 

 may have been destroyed in the 1906 San Francisco earth-

 ANSP,9 LACM.io or USNM." Because L. bilineata may be 

 easily confused with L. polyxystra n. sp., especially in the 

 Gulf of Alaska and Puget Sound, we therefore designated 

 CAS 42650, collected in the Gulf of Farallones off Califor- 

 nia, as the neotype of L. bilineata. Ayres obtained his spec- 

 imen from the San Francisco fish market and noted that, 

 although not common, the species was taken in San Fran- 

 cisco Bay. Lockington (1879a) noted that L. bilineata was 

 most commonly caught "at or near the Farallone Islands" 

 for the San Francisco markets.
