Chilopoda 21 h 
Claw of female gonopods long and well curved, entire, with no trace of lateral 
teeth. Basal spines 3 + 3; acuminate from near middle of length, apically rounded. 
Length, 20 to 30 mm. 
Localities: Washington state; Pullman and Wenatschee. Oregon: Corvallis. 
This species seems to replace E. sierrauagus north of Oregon. It is very 
close in general appearance and structure to the latter species. 
Ethopolys integer alaskanus, n. subsp. 
Though in E. integer proper the head and first dorsal plate are strongly and 
rather coarsely punctate, especially over the anterior portion of the head, 
these parts in the types of the Alaskan form as represented by the types are 
smooth and wholly without punctse or nearly so. 
Posterior angles of thirteenth dorsal plate weakly produced, those of the 
eleventh showing a more slight similar tendency. 
The claw of the female gonopods in the two typical females has a distinct 
tooth on the inner side toward the distal end but none on the outer, being thus 
bipartite instead of essentially entire as in integer or tripartite as in sierravagus. 
In the types from Forrester island a median dorsal black stripe is distinctly 
marked from the caudal end of the fourteenth plate cephalad to the frontal 
suture of the head. These specimens in whole or in part show a distinct reddish 
or chestnut cast. The specimens from Sitka (males presumably of this sub- 
species) lack the reddish tinge, the colour being a dull, nearly uniform, dusky 
olive brown. 
Dorsal spines of first legs in Sitka specimens 0, 0, 2, 2, 1. Dorsal spines of 
second legs in specimens from both localities may be 0, 0, 3, 2, 1 or 0, 0, 3, 2, 2. 
Length of maximum female, 23 mm. 
Localities: Alaska, Forrester island (Ronald and Prof. H. Heath); and 
Sitka.
