1912] Chilopods and Diplopods N74 
First dorsal plate with sharply impressed cervical furrow. On each 
side a furrow which caudad is parallel with caudal margin, from there 
curving obliquely cephalo-ecta. A median longitudinal sulcus cephalad 
of cervical groove. Smooth. 
Second dorsal plate with median longitudinal sulcus on anterior half. 
The two usual paired sulci crossing the entire plate and diverging caudad. 
On each caudo-lateral portion of plate a furrow curving obliquely 
cephalo-ectad as on first plate, similarly taking its origin near caudal 
margin. 
Third and fourth dorsal scuta with median furrow. The paired 
longitudinal sulci less strongly diverging caudad than on preceding 
plate. Furrow on each caudo-lateral portion as in the preceding scuta. 
On the fifth and subsequent dorsal plates the paired sulci become 
nearly parallel, but diverging some at the ends. Median furrow evident, 
but not so the caudo-lateral ones. On each side a longitudinal furrow 
subparallel with the lateral margin, this furrow often broken. On a 
few of the more caudal segments a transverse sulcus on each side parallel 
with and close to the anterior margin. The twentieth plate laterally 
margined for its entire length; the nineteenth all but a short distance 
cauded; the eighteenth not margined for a somewhat greater distance 
caudad and a short distance cephalad; the margination of the seventeenth 
and sixteenth plates similar to eighteenth but extending less caudad 
and cephalad reaching the transverse sulcus; other plates not margined. 
Lost dorsal plate with caudal margin mesally strongly and evenly 
convexly extended. A sharply impressed longitudinal median sulcus 
which does not quite reach the caudal margin. A short furrow parallel 
to the median one opposite its middle portion on each side. 
Prosternum smooth; a median sulcus evident only for a short dis- 
tance distad; transverse sulcus obscure; two weak longitudinal furrows, 
which, close to the mesal line caudad, diverge and are more distinct 
cephalad. Each dental plate with four teeth, of which the three inner 
ones are basally fused, the two most mesal being free only at their distal 
points; a deep narrow incision between the plates; the transverse 
furrow at base of each plate distinct, the two meeting mesally at an 
obtuse angle. 
Basal tooth of prehensorial feet long, subacute, presenting but one 
point. 
Penult article of palpus of second maxilla with a slender spine at 
distal end. 
Ventral plates from the second to the twentieth inclusive with two 
sharply impressed longitudinal sulci which cross the entire plate. 
Last ventral plate narrowed caudad, the sides weakly excurved- 
caudo-lateral corners rounded; caudal margin a little incurved mesally. 
Smooth. Depressed along the median line. A weak furrow sub- 
parallel with and not far from each lateral margin. 
Prefemora and femora of legs of the first to penult pair inclusive 
without any dorsal spines at distal end; all with a tarsal spine, those of 
the first pair with two.
