520 Mr. R. I. Pocock on the Morphology and 
chordeuma as attested by H. monticola, Poc. (Max Webevr’s 
Zool. Ergeb., Chilopoda &c. p. 342, pl. xix. fig. 14.9, 1894). 
The description given of the gonopods of this last-named 
species must be emended as follows :—The legs of the eighth 
pair are reduced to a pair of small, unjointed, apically re- 
curved apophyses, proximally contiguous, distally divaricated 
at an acute angle, and underlying the coxe of the nmth 
pair. Legs of ninth pair with long, stout, subcylindrical 
coxal apophysis, from the base of which rises a slender, 
curved, apically spatulate, backwardly directed flagellum ; 
the second segment (? trochanter) is relatively small; the 
third segment (?femur) enlarged, oval and inflated as in 
Huttoniella, but to a lesser degree. The tenth leg is like the 
ninth in form, although smaller, but the coxal apophysis has 
no flagellum and the third segment is much smaller, shorter, 
and only a little inflated. In the original description the 
ninth and tenth legs were erroneously described as the modi- 
fied appendages of the seventh segment—that is to say, as 
the eighth and ninth. Thus the male of Heterochordeuma 
differs greatly from that of Huttoniella in the form of the 
gonopods, as it also does in the nature of the modification 
affecting the anterior legs. 
Genus HEnpDERSONULA, nov. 
Related to Huttoniella, but differing in the following parti- 
culars :—On the first tergal plate (fig. I. 2) the intermediate 
tubercles are nearer to the external than to the internal. 
On the median segments the internal tubercle is the largest 
of the three. The keels are distinct plate-like processes 
and not formed by the enlarged external tubercle (fig. I. 2 a). 
On the posterior segments the three tubercles on each side 
retain their lateral position, the two internals being widely 
separated from each other in the middle line (fig. I. 2 3). 
Male unknown. 
Type Hendersonula collina, sp. n. 
I have great pleasure in dedicating this genus to Dr. J. R. 
Henderson, of the Christian College, Madras, who sent a 
valuable collection of Myriopods from South India to the 
British Museum some years ago. Amongst these was the 
type of the species described below—the first species of 
Chordeumoidea to be discovered in India proper. 
Hendersonula collina, sp. u.

lateral area of segments pale; antenne blackish, with the
