East-Indian Chilopoda and Diplopoda. 85 
margin, the posterior ones about their diameter from the 
nearest emargination. 
The anal scutum is clavately widened caudad; the caudal 
margin is slightly convex, with the margin wavy, there being 
six crenations with a seta borne on each. 
Sternites each bearing four conical acute processes, one 
mesad of the base of each leg. 
Length to about 110 mm.; width to nearly 18 mm. 
Locality — Borneo :, Sarawak, Ladong (H. W. Smith). 
Type, Mus. Comp. Zool. (No. 4671) ; paratype (No. 4672). 
Platyrrhacus philippinorum, sp. n. 
Black; the keels entirely bright yellow. Legs and 
antennz brown. 
Head above coarsely granular, in front and below more 
finely granular, with a few hairs in clypeal region; vertigial 
sulcus deep. Antenne short and thick. 
Collum wider than head, flat, dorsal surface densely 
granular; a little distance back of the anterior margin a 
transverse row of larger smooth tubercles. 
In the succeeding tergites the keels are raised a little so as 
to make an angle with the adjacent surface of the dorsum 
rather than continuing this outline smoothly. The lateral 
margins of the keels are simply wavy, in no case serrate or 
dentate; anterior and posterior margins appear finely toothed 
from the presence of granules on each. Pores removed 
from the lateral margin by a distance equal to the circular 
area enclosing the pore. Dorsal surface in general densely 
granular; a series of larger granules or tubercles, well 
separated from each other, along caudal border, a second 
series of somewhat smaller ones across middle, and a third 
one towards the anterior border of metazonite. 
In the male gonopods the telopodite curves meso-distad 
beyond the median line, the principal or ventral branch then 
bending ectad and then back caudad, the slender acute tip 
then running first again mesad and the extreme distal end 
bending next forward. The dorsal branch is a comparatively 
short-pointed blade curving dorso-mesad and ending at or 
near the middle line. 
Length (male) about 65 mm. ; width 10 mm.
