East-Indian Chilopoda and Diplopoda. TS 
and only about half-way up to the pore. Striolation of 
prozonite very fine and often in part obscure, oblique as 
usual, none found above level of pore. Both prozonite and 
metazonite dorsally wholly smooth, without markings. 
Comprission of anal valves exceptionally strong, the 
mesal borders being strongly elevated. Anal scutum not 
quite wholly covering the valves. 
Anterior legs of male, excepting the first two pairs, with 
the usual tarsal pads. 
Median plate of gonopods shaped something like the 
wish-bone of a chicken, with the upper ends of the arms 
curving outwards about the bases of the gonopods as usual ; 
the distal plate shorter than the arms, broadly triangular, 
the distal end rounded. ‘he disto-mesal angle of coxal 
piece of anterior gonods extending well beyond the coxa, 
broad distally, the mesal half rising above the ectal, with 
the ectal corner angularly produced and its distal edge 
convex. 
Number of segments sixty and about that number. 
Width of male, 7-2 mm.; of female, to 9 mm. 
Locality—Philippines: Luzon, Mt. Makiling (C. F. 
Baker).

Plokamostrophus guamanus, sp. 0. 
In this species the median plate of the posterior gonopods 
is in the form of a crescentic arch. The median plate of the 
anterior gonopods is in general form like that of mindanao- 
nus, but extends a shorter way distad, has the distal end more 
rounded, and the upper arms shorter and even more strongly 
_ divergent than in that species. The coxal plate of the 
anterior gonopods is longer, and is characterized by having 
the disto-mesal corner rounded, not elevated into an acute 
process. The distal or caudal division differs in being 
exceeded by the coxal plate, excepting the meso-distal 
process, which extends beyond the plate—this process narrow 
as in mindanaonus, but longer. 
Prozonites and anterior part of metazonites black, the 
remaining part of the metazonites ferruginous or in part 
fulvous. Collum bordered all around with light, and the 
median part including many light spots. Head below level 
of eyes and laterally fulvous. Legs and antenne fulvous. 
Segmental sutures mostly obsolete or absent. Surface for 
the most part characteristically densely finely granular or 
shagreened, smoother on posterior part of segments.
