ON THE MYRIOPODA OF BURMA 413 
tergites are either slightly wrinkled and weakly and sparsely 
spicular, or strongly carinate and sub-serially spicular. The 
anal pleurae are generally very long and stout, but sometimes 
considerably shorter — the length possibly depending upon sex. 
The spine armature of the legs is slightly variable but does not 
depart very much from the following arrangement: 1° pair 
with an anterior patellar spur, 15 to 5™ or 6" with an anterior 
tibial spur, 1s* to 17" with two tarsal spurs, 18" with one or 
two tarsal spurs, 19" with one tarsal spur, 20 with or without 
a tarsal spur, 21* always without a spur. Consequently I do 
not think that Dr. Haase’s variety insulare is of very great 
value. The largest specimen obtained measures 65 mm. in total 
length. 
This species ranges from China and Japan to Java and Ceylon.

Although this species has hitherto not been recorded from the 
Oriental Region, it having been described from Mauritius, yet 
it is unquestionably one of the commonest centipedes in Burma. 
Specimens were obtained by Fea at Teinzò, Bhamò, Mandalay, 
Taikkyi (Pegu) and Palon; and by Mr. Oates at Mandalay, 
Rangoon, Thayetmyo, Pegu Hills, Moulmein, S. Tenasserim, 
Reef Island (Tavoy) and Table Island (Andamans). 
It is exceedingly variable in colour, and presents very many 
strong points of resemblance. with Ot. carinatwm. Thus in the 
number of its antennal segments, in the length of these appen- 
dages, in the form and armature of its prosternal maxillary 
plates, in the structure of its tergites and sternites, in the spine 
armature and length of the anal legs, in the numbers of spurs 
upon the walking legs and in the spine armature of its pleurae, 
it is in no way to be recognised from 0. carinatum,; but the 
anal pleurae appear to be slenderer and not so long, there are 
usually fewer spines on the anal femora and the tergites 
although strongly or weakly wrinkled do not appear to be spi-
