East-Indian Chilopoda and Diplopoda. 71 
of the latter is produced caudad to about the same distance, 
or, rather, a little beyond. The arms of the piece above 
form a U-shaped figure, but the upper, i. e. dorsal or attached 
end of each arm, curves ectad about the base of the gonopod. 
The telopodite of the anterior gonopods terminates at the 
lower or free end in a short process from the mesal side, 
which at its tip bends ectad into a short arm at right angles 
to the basal part. 
Number of segments fifty-three. 
Diameter (female) 4 mm. 
Locality.—Philippines: Luzon, Mt. Makiling (C. F. 
Baker).

Trigoniulus major, sp. u. 
This species, in the lack of a male, referred to this genus 
with some doubt, resembles some specimens of 7. lumbri- 
cinus in being of a brick-red colour, but the legs are flavous, 
not ferruginous. The caudal borders of segments a deeper 
red. Head and anal segments, especially the valves, lighter, 
more flavous. 
Sulcus on head evident on vertex and below. Surface in 
general smooth. Eyes rather small, subcircular, widely 
separated. Antenne short. 
Whereas on the body of Jumbricinus there is a deep, fine 
longitudinal sulcus across the plate at the level of the eye 
on each Side, no such sulcus is evident in the present species ; 
but below this level there are several wide and shallow 
longitudinal furrows, not extending to either border. 
The segments in general a little constricted, a shallow 
depression encircling each segment along the suture, which 
is obscure and above not evident. Below and part-way up 
the side the usual longitudinal striz across the metazonite. 
Striz on prozonite below finer and more numerous than on 
the metazonite, those towards the pore in particular curving 
up cephalo-dorsad, all more or less branching ; above pore 
across dorsum replaced by a meshwork of numerous small, 
curved, impressed lines, not mingled with puncte. In furrow 
numerous puncte as well as coarser curved impressions. 
Metazonites with some lines at edge of furrow, but other- 
wise essentially smooth above. 
Anal scutum not wholly covering the valves above. Valves 
strongly compressed in the usual way. 
Number of segments fifty-five.
