iraens (8117) of a Lepeoplitheirus^ taken from the Kiug Salmon {Oncor- 

 hynchus chouicha), in Kenai, Alaska, by Mr. W. J. Fisher, July, 1880^ 

 which differ but slightly from this species, and may possibly be only a 

 variety of it. The principal differences noticed were as to the second 

 pair of foot-jaws ; which are proportionally shorter, and are armed with 

 an elongate crest on the front edge near the middle. 



The specimens from Mr. Turner, Ungava Bay, Labrador, are not la- 

 beled as to the fish from which they were obtained, and as that ob- 

 server is still absent from this country, it is impossible to more than 

 surmise their origin. His notes will undoubtedly furnish the desired 

 information on his return.
