1918] Chamberlin—Myriapods from Nashville, Tennessee Q7 
Number of somites 44 to 48. 
Average length near 50 mm. with diameter 4.8 mm. 
Localities. Glendale Hills, south of Nashville. Nine specimens 
April 21, 1917 and three specimens March 25, 1917. 
17. Parajulus pennsylvanicus (Wcoc). 
Beyond Glendale, Oct. 14, 1916. Cne female apparently this 
species. 
18. Parajulus nigrans sp. nov. 
The color is very dark, blackish throughout without definite 
paler spots or annuli. Feet also dark. 
Body rather slender, obviously narrowing caudad. In general 
smooth, not pilose, but a few stiff, somewhat curved sete on last 
segment and anal valves. Somites strongly longitudinally striate 
beneath and across lower part of sides. 
First segment long, with the lower margin straight; margined 
below and over lower part anteriorly but not at all striate. 
The anal plate above is acute but is not at all produced; it is 
clearly exceeded by the anal valves and bears a series of sete along 
its caudal margin. Anal valves mesally margined. 
Head with a median vertigial sulcus ending at a deeply impressed 
arcuate transverse sulcus extending between the eyes. Nearly 
smooth. Eyes triangular, each composed of about 36 ocelli ar- 
ranged in 8 transverse series. 
Repugnatorial pore moderate, contiguous or nearly so with the 
suture which is straight or rarely very slightly curved opposite the 
pore. 
In the male the mandibular stipes strongly produced at the an- 
tero-inferior angle, the apex of the process being on nearly the same 
level as the inferior margin of the labrum. 
Each first gonopod of the male is placed antero-lateral of the 
corresponding second one. Its anterior division is a flat plate about 
half as high as the posterior division against which it lies; its distal 
end is rounded. The second or posterior gonopods rise clearly 
above the anterior plates. Each above its base is a thin, flat 
blade with edge subapical, which near its middle curves caudad and 
then somewhat dorsad. Not at all narrowing dorsad, its free distal 
end truncate; from the basal portion a slender acutely pointed 
blade curves mesad and crosses the one from the other side.
