chamberlin: myriopoda of the Australian region. 11 



being wholly smooth, presenting merely a long, nearly straight chiti- 

 nous edge which is slightly emarginate at the middle. Coxopleural 

 processes long and acute; coxopleural pores extending dorsad to the 

 tergite. Last ventral plate caudally incurved or somewhat angularly 

 excavated. Anal legs very long and slender as in the preceding 

 species; spines of prefemur both well dexeloped, the ventral one about 

 equalling the diameter of the joint at the level of its base. 



Length, 10 mm.; anal legs, near 6 mm. 



This species stands apart with the following one from all others in 

 having tergites margined much farther forward, the margination 

 being distinctly present from the seventh plate caudad. 



20. Otocryptops aberrans, sp. nov. 



Type.— M. C. Z. 1,941. Fijis: Nansori, Vesari (W. M. Mann). 



Color ferruginous. 



Head not margined, smooth. Antennae with first three articles 

 nearly glabrous. Anal tergite with caudal margin mesally strongly 

 bulging beyond lateral angles; the latter above with an acute spine. 

 Ventral plates smooth, unfurrowed. Prosternum with anterior 

 margin lightly convex, bearing two distinct black teeth on each side, 

 of which the mesal is larger. Coxopleural process long and acute, 

 much exceeding the ventral plate, pores reaching to the dorsal plate 

 above. Anal legs very long and slender; femur with both spines 

 well developed; the ventral larger, length less than diameter of joint. 



Length, near 18 mm. Length of anal legs, near 8 mm. 



This species is readily distinguished from the others in ha\"ing the 

 tergites clearly margined from the se^•enth to ninth caudad. 



20a. ScoLOPOCRYPTOPs miersi fijiensis, subsp. nov. 



Type.— M. C. Z. 1,945. Paratypes.— M. C. Z. 2,023. Fijis: 

 Nasoqo, Xadarivatu (W. M. Mann). 



Scolopocnjpiops miersi has heretofore been recorded only from the 

 Western Hemisphere. The present form agrees very closely with 

 AVest Lidian specimens in most details; but in the anal legs the ventral 

 spine is much larger as is also the dorsal spine which is of about the 

 same size as the ventral spine in inicrsi proper; furthermore, the 

 ventral spine is farther distad than the dorsal one, the reverse being 

 true in miersi, and it is nearer the middle of the length of joint (dis-
