MILLIPEDS OF PANAMA—LOOMIS 81 
Description: Body very small, short, and broad with only 19 
segments; lateral carinae descending less obliquely than the dorsum; 
dorsal surface of all segments with low swellings rather than pro- 
nounced tubercles, the swellings and intervening spaces beset with 
distinct rounded granules. 
Head with labral and clypeal area separated from front by a con- 
spicuous depression. Antennae short, strongly clavate, joints monili- 
form; joint 5 wider than long, joint 6 of same width but longer 
than any other. 
Segment 1 with anterior margin 10 lobed; disk with a transverse 
row of 6 swellings in front, followed by a row of 4 others. Ensuing 
segments with outer margin of normally poreless keels three lobed, 
the normally poriferous ones four lobed although no pores were seen. 
Last segment small, crossed by a row of four setae with four others 
clustered at the slightly deflexed apex. Preanal scale as long as 
wide, with apex broadly rounded. 
Gonopods each with coxal joint galeate, an outer simple branch 
curving mesally, and a median bifurcate branch directed caudally.

Description: Length 3 mm., width 0.6 mm.; body composed of 
19 segments; color in alcohol ight brown. 
Labral and clypeal area of head separated from front by a broad 
depression, surface smooth and shining; clypeus crossed by a trans- 
verse band of fine erect setae; sides of head inflated laterad of antennae, 
granular and setose; surface between antennae flat, continuous 
with vertex and, like it, evenly finely granular; behind each antenna 
is a small, sharply raised, rounded tubercle; antennae separated 
by a little more than the diameter of a socket and short, moniliform- 
clavate, with joint 5 wider than long, joint 6 longest (fig. 19). 
Segment 1 (fig. 1h) concealing head from above; front margin 
somewhat raised, divided into 10 lobes, behind them a transverse
