MYRIOPODA FROM BURMA 397 



Sig. L. Fea. Differs from the preceding in its much longer and 

 thinner ' tail ' (^). 



13. Spirolbolixs spiovilifei*, sp. n. 



9 . Colour deep slate grey, the legs, antennae, labral region 

 of head, anal valves and posterior borders of somites testaceous 

 or ochraceous. Head smooth , shining , convex , longitudinally 

 sulcate above and below, the sulcus obsolete in the middle, 

 with 8 piliferous pores above the labral excision. Eyes composed 

 of about six transverse series of ocelli , separated by a space 

 greater than twice a diameter. Antennae short , much shorter 

 than the head. First tergile projecting inferiorly nearly as low 

 as the second, gradually narrowed laterally, inferiorly truncate, 

 the anterior angle obtuse, the posterior nearly a right angle , a 

 single anterior marginal sulcus. The rest of the tergites without 

 scobina, nearly smooth in front, the median portion obliquely 

 striate inferiorly, the striae above passing into a sculpturing 

 that consists of crescentic or horse-shoe shaped impressions; the 

 posterior half almost smooth above, laterally striate up to the 

 pore, higher than the median portion, the two being separated 

 by a groove like depression, the transverse sulcus entirely ob- 

 solete above, weak below and extending as high as, or a little 

 higher than the pores; pores conspicuous, above the middle of the 



(') I here subjoin the description of a new species of Spirnbolus that is closely 

 allied to Sp- cauclulanus . 



Spirobolus dLollfusii , sp. n. 



Colour (in alcohol) pale olivaceous, antennae and legs ferruginous, posterior bor- 

 der of somites paler with a bright blood-red spot upon the middle dorsal line. 

 This species agrees so closely with Sp. caudulanus of Karsch that a detailed des- 

 cription is not necessary. It differs in colouring inasmuch as there is a blood- 

 red spot on the posterior border of the middle of the back. In caudulanus there 

 is never a spot in this position but often a transverse blood-red band upon the an- 

 terior half of the segment. In the male moreover, the anterior lateral laminae 

 project below the apex of the median lamina, and the inferior process of the pos- 

 terior laminae Is more produced and lobate, whereas in caudulanus the apex of 

 the median lamina projects as low as that of the anterior lateral portion, and the 

 apex of the posterior portion is not rounded.
