MR. E. I. POCOCK ON THE 



Lateral portions of first dorsal plate very much narrowed; 

 anterior margin meeting the posterior margin in a rounded 

 angle ; margin of the angle and of the lower half of the dorsal 

 plate with raised border ; not striated. 



Lower portion of the clypeus with well-marked sulcus, upon 

 each side of which are four punctures. 



Posterior segment produced into a more or less pointed process, 

 which projects beyond the margins of the anal valves. 



Margins of anal valves convex and not compressed. Sub-anal 

 plate triangular, with posterior angle rounded. 



Anterior lamina of copulatory foot wide above, narrow below, 

 and at its distal end abruptly passing into a slender projection ; 

 inner margin nearly straight ; outer margin sinuate. Laterally 

 it is in contact with the posterior lamina, which is pointed below, 

 and bears near the distal extremity on the outer side a conspi- 

 cuous indentation. Above there is a simple slender piece, articu- 

 lated to the free extremity of which is a backwardly-projecting 

 claviculiform rod. To the posterior end of this rod articulates 

 the central lamina, which apparently consists of two segments, 

 an upper and a lower ; the two together, being hollowed out 

 behind, form a complete sheath, chitinous in front, membranous 

 in the rear. Upper segment slightly curved, with smooth round 

 anterior margin, giving off at the point of junction with the 

 lower segment two short processes ; lower segment much smaller 

 than the upper, terminates below in a pointed projection. 



Four specimens, two males and two females, from Elphinstone 

 Island. 



Note. — At the time when I began to draw up this Report upon 

 the Myriopoda of the Mcrgui Archipelago, it was not possible, 

 owing to the lack of similar Reports, to compare directly the 

 fauna of tin's group of islands with that of any one district in the 

 Oriental Region. An exception, however, to this statement must 

 be made in the case of Ceylon ; for the Myriopoda of this island 

 have been worked out by Mons. A. Humbert. All that could be 

 said in tin's respect was that the islands present general faunistic 

 affinities — which certainly is true enough — with the rest of tho 

 Indian and Jndo-Malayan area. 



But while the present paper has been in the hands of tho 

 printer! I have fortunately l>ad an opportunity of examining 

 two extensive collections of Burmese Myriopoda. The first of
