MYRIOPODA FROM BURMA 395 



thing is true of Oates' specimens from Reef Island and S. Te- 

 nasserim. Hitherto the 9 only has been known. The c/" is of 

 smaller size and considerably thinner ; the anterior legs are 

 unmodified, and the distal tarsal segment is padded beneath. 

 The anterior median lamina of the copulatory foot has two long 

 slender superior arms, the lower half being narrowed and trian- 

 gular, tlie anterior lateral portion projects inferiorly as low as 

 the apex of the median, its internal inferior- angle being acute, 

 its external inferior angle i-ounded and the border between them 

 emarginate ; the posterior lateral lamina projects a little below 

 the anterior and is roughly hammer-headed in shape. The largest 

 example measured is 83 mm. in length. The somites seem to 

 vary in number from 50-53. 



Mr. Oates obtained at Pynimana (N. of Tungoo) a single 

 female Spirobolus, which is doubtfully referable to this species. 

 I can not distinguish it by any reliable characters from the 

 Tenasserim form, but possibly the discovery of the male will 

 show that the two are in reality distinct. 



11. Spirolbolixs Tiioii.lnxein.eMLsis, sp. n. 



Colour reddish ochraceous, the anterior border of the first and 

 the posterior border of all the somites, ferruginous, head fuscous 

 above, legs and antennae ferruginous. 9 • l^ead nearly smooth, 

 punctulate, feebly sulcate, with two labral pores on each side. 

 Eyes separated by a space that is about equal to twice a dia- 

 meter, composed of 7 transverse rows of ocelli, the inner border 

 straight. Antennae shorter than the head. First tergite punctu- 

 late , extending inferiorly as low as the second , the anterior 

 border straight and sulcate, the angle acute, rounded and the 

 posterior border directed obliquely upwards are backwards from 

 the angle. The rest of the somites without scobina, the trans- 

 verse sulcus reaching and extending only as high as the pore; 

 the anterior third of each smooth , the middle third minutely 

 striolate and conspicuously punctured above longitudinally, but
