long or short, bare or plumous bristles; in one of these groups, the proximal one, three bristles 

 were observed and four in the other. A weak chitinous list runs from the posterior dorsal corner 

 of the comb to these groups of bristles. The epijjodial appendage is somewhat ear- 

 shaped, but perhaps not quite so marked as in the genns Aster ope; its marginal bristles are of the 

 same type as in this genus. 



Sixth limb (fig. 12): — The bristles along the dorsal two-thirds of the anterior edge of 

 this limb are arranged in three rather distinct rows, which are about parallel to each other; the 

 following numbers were observed in the specimen that was investigated: 33 bristles in the outer

row both on the right and left limb, 25 — 27 in the middle row and 27 — 30 bristles in the inner 

 row; in addition there were two or three bristles dorsally inside the inner row. Most of these 

 bristles are moderately long, some rather short; all or at least the great majority of them are 

 finely plumous. Along the ventral third of the anterior edge of this limb there is only one row 

 of such bristles; this row continues ventrally out on the lateral side of the anterior sole-shaped 

 part of the limb; 25 — 30 bristles were observed in this row; its dorsal bristles are somewhat 

 shorter than the ventral ones. Along the anterior three quarters of the ventral edge of this limb 

 there are about 80 — 90 bristles situated irregularly close together; of these those situated 

 laterally are comparatively long, the medial ones more or less short. Some of the long ones 

 have long, stifi secondary bristles at the middle and short hairs distally; others, like the shorter
