1918] Chamberlin—Myriapods from Nashville, Tennessee 29 
Basal lobe of each gonopod strongly setose on mesal side. Ex- 
terior division with setze on posterior edge over basal and middle 
region; the branchis constricted above here into a slender blade of 
uniform width until the next to the distal fifth of length over which 
it is expanded to nearly double the width and then again narrows 
to a tongue which at its distal end is attenuated into a slender, 
distally bristle-like tip. About the distal three-fifths, or less, of 
the exterior blade is strongly bent upon itself roughly into a U-shape, 
with the slender tip at right angles to the arm bearing it. The 
basal spine short, slight, curved, acute. 
Length about 39mm. Width 10 mm. 
Locality. Glendale Hills, south of Nashville, April 21, 1917. 
Two adult males, one adult female and four immature indi- 
viduals. Closely related to F. rileyi Bollman, described from 
Macon, Georgia. 
25. Fontaria mimetica sp. nov. 
General color at present dusky brown with the carinz and bor- 
ders of somites yellow. Of reddish caste and probably red in life. 
The posterior band of color usually widest at middle. The first 
somite with anterior as well as posterior border of the lighter color. 
Head light at sides and below level of antenne. Antenne deep 
reddish brown or chestnut. Legs yellowish. 
Body conspicuously narrowed cephalad over the first four so- 
mites. Carinee very much as in glendalea but with the caudal 
angles in general more produced. 
Repugnatorial pore dorsal in position, widely removed from 
lateral edge. 
Vertigial sulcus distinct. Occipital foveole 2+2; antennal and 
clypeal 1+1. 
Sternite of third somite in male with two processes fused into a 
single conspicuous median body which is somewhat constricted at 
base. Fourth sternite with two separate subconical processes. 
Coxe without spiral process aside from those giving exit to the 
genital ducts on the second pair. 
Fifth sternite with two low, rounded eminences. 
The general form of the gonopods as in glendalea, strongly 
coiled nearly into a complete circle open below, but the exterior 
division much broader, at first cylindrical, then flattened and near
