Mouth. Labrum distinctly bowed with a mu ol about jo rounded chitinous knobs 

 at t ie teeth and with a series ol delicate hairs inserted in trom of the knobs 



id at the base, conical with several bristles along the outer margin and a 

 h bristles at the tip. 

 Mandibles (fig. 6 with three teeth and the inferior angle. The second and third 

 tooth and the third tooth and the inferior angle at nearly equal distances from another, the 

 iïrst and second tooth at twice the dist. mee ol the other teeth. The inferior angle is slightly 

 1 at its extremity and terminates in a nol very pointed tooth, much ressembling the other 

 eth. Very small, sharp spines occur along the upper edges of tooth 2 and 3, as also 

 along the upper edge and along the under edge near th< extremity of the inferior angle. Near 

 the dge the surface of the mandible is furnished with numerous hairs which are placed 



in groups of two <>r three; some hairs reach over the free edge, numerous others are planted 

 along the inferior margin. 



Maxillae (fig. 7) with three strong spines above a rather broad notch and the 

 part beneath the notch slightly produced. Between the three nj >] x • r sj)ines, of which the first 

 is 1>\- far the strongest, a few delicate hairs are planted, one of which is distinctly serrated. 

 In the notch are a few short hairs and about 10 rather strong spines, arranged in a doublé 

 row along the lower part. Hairs in groups ol two or three on the surface near the free edge; 

 a n>w of stronger hairs along the inferior margin and a few hairs forming a group at the upper 

 margin near the insertion of the upper spine. Apodeme rather long. 



(•titer maxillae short, rounded at the extremity with a dense tuft of spines near 

 that extremity and along the inner side. Between the longer spines are inserted numerous very 

 delicate hairs. 



Cirri short and nearly straight, hardly curved. First pair very short, 2 nd — 4* pair 

 longer than the others, s' h and 6 th pair considerably shorter than the foregoing ones. 



First pair placed close to the mouth, at a little distance trom the second. with 

 short and rather unequal rami of 5 and 6 segments. The shorter ramus has the first segment 

 indistinctly divided into two segments and the four following ones decreasing in dimension. Hairs 

 on the segments numerous, increasing in strength from the first to the fifth segment; about 

 the middle of its length each segment has a distinct transverse row of longer hairs. The last 

 lent bears two claw-like spines at the tip. The longer ramus is considerably broader; it has 

 six distinctly separated segments, decreasing in dimension from the 1 ' : to the o !h . The lower 

 densely covered with hairs, the distal in a less degree. The last segment has four strong 

 spines at the tip: these are not (piite so strong and a little less curved than those al the tip 

 of the shorter ramus. 



The 2"' 1 to 4 ,h cirrus has nearlj equal rami of 9 to 10 segments. The shape of the 



3 almost quadrangular, with the exception of the first segment of each ramus, which 



trom 2 to 3 times as long as broad and of the last si m.nt. which is small and rounded 



tip. I he bristles form transverse rows near the extremity of each segment and a tuit
