scriptious seem to apply inure to the younger stages of the latter. 

 Concerning the status of Jitlns imit<i>in* Cope, I have regarded it as 

 identical with P. jx-iiiiNi/lraiiiciiN, but it may represent a geographical 

 form, as those from farther south have more segments and attain a 



larger si/.e. 



2. Parajulus zonatus, sp. nov. 



.JJi<iii<>niN. Belated to P<trqpul/U8 furcifer (Harder), but the anal seg- 

 ment produced into a strong spine, which passes considerably beyond 

 anal valves; segments with short, deep sulcations; color dark brown, 

 posterior border of segments pale.

Hhitt. Chehalis, Lewis County, Wash. Terr. 



Dexcri/ition of type. Brown, posterior border of segment pale, usual 

 yellow lines and spots absent, legs dark. Robust, segments with nu 

 merous short sulcations, not pilose. Vertex rough, a distinct median 

 sulcns, setigerous t'oveola- present. Antenna 1 equaling width of body. 

 Ocelli 4G-7 to 5(5-8, arranged in a triangular patch. Segments, 52 to 

 53. Last segment produced into a large, straight, robust spine, pass- 

 ing beyond anal valves; anal valves slightly marginate, sparsely pilose; 

 anal scale large, not passing beyond anal valves, pilose, liepugnato- 

 rial pore large, more deeply impressed than in furcifer, placed near 

 transverse suture, which is nearly straight. 



Pairs of legs, 93 to 95, moderately long. Length of body, 25 to 40""" ; 

 width, 2 to 2.5""". 



This species differs most strikingly from P. furdfer by having the 

 last segment produced considerably beyond anal valves, and also by 

 the plain color. In P.furcifi'r the last segment does not pass beyond 

 the anal valves, and the yellow lines and spots, which are absent in 

 zouatu* and generally present in other species, are very bright; in fact, 

 much more than in any other species. 



The male genitalia, of which 1 have said nothing, differ very remark- 

 ably from that of I'.fiircifer or /'. orei/oni'iiNix. 



1 have examined two males of this species. They were collected by 

 Mr. (leorge Gregg, of Chehalis, Wash. Terr. 



3. Craspedosoma atrolineatum, sp. m>v 



Diagnosis. Light brown, Literal canine and a median dorsal line 

 dark. Male: Femur of fourth pair of legs produced at the middle into 

 a knob-like process armed with a few rather large tubercles; femur of 

 ninth pair with a cylindrical, tapering basal lobe, which is slightly tu 

 berculate. 



Type.U. S. Nat. Museum. 



Habitat. Glacier, British Columbia. 



DcNcription of typr. Light brown, lateral caiina- and a median dorsal 

 line black ; legs pale. Robust, attenuated anteriorly and posteriorly, 

 back not flattened. Ocelli very distinct, arranged in a subtriangnlar
