MYRIOPODA FROM BURMA 403 



third somite. Head transversely rugose and punctured below , 

 with a crenulate ridge along its upper border and a frontal 

 sulcus, smooth or -very nearly so above. Eyes separated by a 

 space that is about equal to a diameter, with inner angle acute, 

 composed of about 7 transverse series of ocelli. Antennae ex- 

 tending nearly to the third somite, a little longer than the head. 

 First ter gite smooth or finely rugulose above, laterally narrowed 

 the anterior and posterior border of the lateral portion being 

 lightly emarginate , the anterior and posterior angles nearly 

 right angles, the anterior strongly thickened, the posterior marked 

 -above with many longer and shorter striae. The rest of the so- 

 mites with a strong transverse sulcus, the area in front of which 

 is transversely striolate , while the area behind it is longitudi- 

 nally striate as high as the pore, and the upper portion varies 

 from being almost smooth to finely punctulate with some an- 

 terior abbreviated striolae. Sterna smooth. Ventral grooves short. 

 Pores about the middle of the side, a little nearer to the sulcus 

 than, to the hind margin. A?ial somite; tergite produced into a 

 straight tolerably stout, blunt caudal process, projecting well 

 beyond the valves, and conspicuously constricted at its base. 

 Valves moderately convex, with their border somewhat widely 

 compressed ; sterilite triangular not defined behind by a sulcus. 

 Legs with a single seta on the lower edge of each segment , 

 those of the anterior end, liowever more thickly hairy below. 

 c/. Head inferiorly smoother ; the anterior angle of the first 

 tergite produced into a large, blunt, rounded, forwardly direc- 

 ted process. Legs with the fourth and fifth segments padded 

 beneath. Copulatorg feet; anterior lamina with inner edge nearly 

 straight, slender above, expanded and davate below, the poste- 

 rior surface giving off an externally divided subquadrate notched 

 lamina: the protrusible portion slender, terminating below in 

 a simple pointed style, bearing in its lower half an elongate, up- 

 wardly directed slender process, which distally divides into two 

 prongs, an outer simple and pointed, an inner distally expanded 

 and hairy. 



No. of somites 69-73.
