324 ME. K. I. POCOCK ON MYRIOPODA 



Eyes separated by a distance that is a little greater than a 

 diameter. Antenncd shorter, only projecting beyond the first 

 tergite by the terminal segment. 



Eirst tergite narrowed laterally, without grooves or ridges, 

 the posterior border strongly emarginate, and the posterior angle 

 acute ; the anterior angle rounded and very obtuse, the margin 

 thickened and defined above by a sulcus, which inferiorly dis- 

 appears and expands into a depressed area. Rest of the tergites 

 very lightly longitudinally rugulose behind, the strise anteriorly 

 extending nearly as high as the pore, but posteriorly reaching 

 only halfway up. Anal tergite slightly constricted above, the 

 caudal process robust, blunt, and not upcurled at the apex ; the 

 valves projecting posteriorly in their upper half, and widely com- 

 pressed but not sulcate above, not compressed below ; steriiite 

 not defined by a sulcus. 



Copulatory feet with anterior lamina narrow above, expanded 

 and spatulate below ; the sj)urs on the protrusible portion rising 

 on the same level at a point distal to the point of origin of tlie 

 membranous lamelliform piece, one of them about twice the 

 length of the other, and more slender and curved. 



Number of somites 69. 



Length nearly 200 millim. 



Hab. A single male example from Baram, N.W. Borneo (C 

 Hose). 



This species differs from all the preceding in having the anterior 

 augle of the first tergite very obtuse, and the posterior acute and 

 slightly produced ; and in that the caudal process is stouter, blunt, 

 not upcurled, and the margins of the valves are not compressed 

 below. 



Spieosteptus Eveeettit, sp. n. 



Colour almost as in the preceding, but with the legs and 

 antenDse brighter, and the whole anal somite black. 



Eyes separated by a distance a little greater than a diameter 

 AntennoB short, overlapping the first tergite by their apical 

 segment. 



Eirst tergite laterally narrowed, the anterior and the posterior 

 border lightly emarginate, the anterior angle rounded and very 

 obtuse, the posterior angle blunt, but smaller than a right angle. 

 The rest of the tergites smooth above, the strias even at the 

 hinder end extending almost up to the pores.
