MYRIOPODA FROM BURMA 391 



plate from edge to edge ; the intermediate area occupied by 

 an anterior row of 6 carinae and posterior row of 5, interca- 

 lating but not overlapping at their free extremities on the 

 summit of the tergite , all the carinae of the posterior series 

 usually entire. The other tergites furnished with a transverse 

 series of 9 carinae , the first and ninth being situated just 

 below the middle of the sides. On the first two segments these 

 carinae are simply notched at the summit, in all the others they 

 are completely divided into an anterior and a posterior tubercle, 

 of which the tubercle bearing the pore is the largest. 



No. of somites up to 61. 



Length up to 26 mm. 



Several examples from Farm Caves, near Moulmein, obtained 

 by Sig. L. Fea. 



This species may be recognised from C. doriae by the obso- 

 leteness of the eyes , its paler colouring , the completeness of 

 the two exterior keels on each side of the first tergite and of 

 the keels of the posterior row in the summit of this plate. 



5. Oamlbala calva, sp. n. 



Colour nearly black or pale brown with the head and an- 

 terior three or four tergites testaceous. Head smooth , convex ; 

 eyes consisting of an oblic|uely vertical series of 4-6 ocelli. First 

 tergite laterally truncate on a level with the eyes; with one 

 complete and two very short crests above the margin, the rest 

 of the plate smooth without crests , the 2."^ and 3.'''^ tergites 

 feebly crested above. The posterior elevated half of the rest of 

 the tergites furnished with about 21 crests, which extend from 

 side to side from a point on the inferior half of the lateral 

 surface, five of these ci-ests lie on the dorsal surface between 

 those that bear the pore ; the tubercle of the pore large and 

 rounded, each crest almost entirely divided into two by a me- 

 dian notch. The anterior half of each somite furnished with 

 a transverse row of anteriorly abbreviated cristules. Anal ter- 

 gite without crests. Legs hairy beneath.
