NOTES ON MYRIOPODS FROM ALASKA AND WASHINGTON 



BY RALPH V. CHAMBERLIN, PROVO, UTAH. 



Through the courtesy of Prof. Harold Heath and Dr. E. Bergroth, I 

 have received for study two small collections of rnyriopods from Alaska 

 and the State of Washington. The material received from Prof. Heath 

 was collected on St. Paul Island, Alaska, during the summer of 1910. 

 The specimens sent by Dr. Bergroth were taken by him several years ago 

 at Snettisham, Alaska, and Bremerton and Madison, Washington. 



1. Lithobius sulcipes Stuxberg. 



Two females and a male from St. Paul Island, Alaska. 



It is doubtful whether Z. stejuegeri Bollman can be maintained as a 

 species distinct from this one. Z. arcticus Attems, described from 

 Behring Island, whence Bollman's types also came, is likewise very 

 close to and probably not different from the form described as stejuegeri. 

 In the description of Z. stejuegeri, as published in the Bull. U. S. Nat. 

 Mus., No. 46, p. 200, the spines of the anal legs are given as 1,3, 2, 6 ; 

 but there seems little reason to doubt that the 6 is here a misprint for o, 

 and consequently that Atlems's stated ground for separating his arcticus 

 is fictitious. The claw of the female gonopods varies from practically 

 entire, as stated by Stuxberg for sulcipes and by Attems for some speci- 

 mens of arcticus^ to trilobed, as in the types of stejuegeri and part of the 

 specimens upon which arcticus was based.
