1912] Chilopods and Diplopods 145 
Antenne very short, reaching to or nearly to the sixth segment; 
articles 25, of which the second is longest, those immediately following 
not abruptly shorter but only very gradually decreasing in size distad. 
Eyes about 11 to 14 in number, arranged in four series; thus, 1+ 5, 
4, 3, 1 and 1+ 4, 3, 2, 1. The single ocellus much the largest, sub- 
vertically elliptic or oval. 
Prosternum 1.5 times wider than long or slightly more. Teeth 2+2, 
subequal, acute, with line of apices manifestly recurved. Median inci- 
sion rather wide and deep with its sides concave. Ectal spines much 
more slender than the teeth, bristle-like distad, acute. 
Coxal pores: circular, of moderate size; in number, in type specimen, 
3, 4. 4. 3. 
No spines of posterior coxee evident. Spines of first legs

crassate, the prefemur particularly elevated dorsally; femur conspicu- 
ously excavated dorsally, the excavation extending from end to end as. 
a broad and rather deep furrow; the tibia much less swollen than the 
femur, complanate or shallowly furrowed longitudinally on dorsal 
surface; hairs short and straight, more numerous on dorsal surface of all 
joint but nowhere dense or forming bunches; articles not laterally 
furrowed. Penult legs crassate in about same degree as the anal but 
the tibia relatively larger; distal end of tibia obliquely excised at dorso- 
caudal corner and bearing there a triangular plate or keel-like lobe 
which lies longitudinally with the elevated end caudad; prefemur, 
femur and tibia longitudinally furrowed above, but the furrow of femur 
scarcely more developed than that of the other articles and this article 
not otherwise especially modified; none of articles bearing bunches of 
hair, the latter being everywhere sparse; tarsal joints abruptly more 
slender. 
Gonopods of male wide, truncate distad, flattened in an ecto- 
ventral dorso-mesal direction; bearing a few short bristles in a row 
along distal edge of ventral side. 
Body strongly narrowed from eight plate forward to the first which 
is clearly narrower than the third; the eighth and tenth plates of equal 
width and much wider than the head, the latter in type being even 
slightly narrower than the third plate. Body about 714 times longer 
than width of tenth plate. 
Length of type (a male) 12.5 mm.; of antenne 5 mm.; width of 
tenth plate 1.7mm. Width of head, first, third, eighth, and tenth plates 
to each other about as 18, 17, 19, 24 and 24.
