MYRIOPODA.FROM BURMA 405 



valves, with a slight constriction at its base; valves prominent, 

 with margins strongly compressed ; sternite small, defined by a 

 groove. Legs short, mostly with one seta on the lower surface 

 of each segment. </. Face smoother, the anterior angle of the 

 first tergite, thickened, slightly produced and rectangular. Legs 

 longer, with fourth and fifth segments padded beneath. Copu- 

 latory feet as in figure ; the protrusible portion bearing a huge 

 upstanding spur, with a smaller spur attached to an expanded 

 laminate portion. 

 ■ No. of somites 68-70. 



Length up to about 80 mm. ; width 5.5 mm. 



Locality Double Island (S. of Amherst j, collected by E. W. Gates. 



22. Spii-ostreptiis ta-voiensis , sp. n. 



Closely allied to the preceding. 



Colour of the somites is posteriorly more fuscous than ferru- 

 ginous , and the antennae and legs being clear ochraceous 

 yellow contrast strongly with the colour of the body, the anal 

 somite is entirely fuscous. The upper surface of the body varies 

 from being finely striolate and punctulate to entirely smooth. 

 The anterior laminae of the copulatory feet are more robust than 

 in oatesii and the protrusible lamina is very distinctly formed 



No. of somites 68-70. 



Length of adult 80-90 mm. ; width of latter 6 mm. 



Locality Reef Island off Tavoy (E. W. Gates). Both the pre- 

 ceding species appear to be allied to lankaensis and feae, but 

 they may be at once recognised from both by the strong sulci 

 and ridges which mark the lateral portion of the first tergite. 

 Also the copulatory feet are different. 



23. Spirostreptus doriae , sp. n. 



Colour black or very deep brown ; lower half of head casta- 

 neous, antennae and legs ochraceous. Head punctulate above, 

 very lightly wrinkled also. Eyes large separated by a distance
