slightly outward. Inferior appendage as long as the superiors, 

 widely bifid in its apical three-fourths, its branches not quite 

 as divaricate as the superiors, slightly divergent in their basal 

 half, slightly convergent in their apical half, the place of change 

 of direction coinciding with the position of an acute superior 

 tooth ; tip of each branch obtusely rounded, no apical tuft of 

 hairs ; each branch has also a smaller basal superior tooth. 



llama n sp. 



ioth abd. seg. with no dorsal tubercle, a double median group of spin- 

 tiles taking its place. 



Superior appendages somewhat longer than 10, each one in dorsal 

 view having the inner edge concave, the outer convex and 

 almost angulate at two-thirds' length whence the appendage is 

 obliquely truncated backvvardly and inwardly to form a rather 

 acute apex ; in profile upper and lower edges divergent to the 

 apex which is emarginated almost in a semi-circle, thus form- 

 ing two rather acute tips, only the upper of which is clearly 

 visible in dorsal view. Inferior appendage three fourths as 

 long as the superiors, widely bifid in its apical half, branches 

 less divaricate than the superiors, each branch with an acute, 

 superior, basal tooth near the outer margin and a bifid apex 

 (seen in dorsal view), the outer part of which is the stouter 

 and is directed laterally outward, while the inner part is direc- 

 ted backward ; no apical tuft of hairs .... quadratics n. sp. 

 Superior appendages slightly longer than 10 (which is greatly swol- 

 len), similar in dorsal view to those of qnadracies ; in profile 

 view directed downward, apex obliquely truncated upwardly 

 (dorsad) and backwardly (caudad), the truncated margin 

 crenulate. Inferior appendage three-fourths as long as the 

 superiors, widely bifid in its apical half, branches much less 

 divaricate than the superiors, each branch with a simple ob- 

 tuse apex and 4-5 superior denticles in a row parallel to its 

 inner margin . . tumefactus n. sp. 



Superior appendages hardly longer than 10 (which is swollen), sub- 

 conical, thicker at the base on the inner side, divaricate as 

 much as the width of the segment, apex obtuse, curved a little 

 downward and inward and resting on the fork of the inferior. 

 Inferior appendage longer than the superiors, divided as far as 

 the base, its branches as divaricate as the superiors, curved 

 upward, and in profile view forked at the tip. upper branchlet 

 acute, the other with its tip enlarged in the form of a palette, 

 emarginate in a semi-circle exteriorly, with a strong tuft of yel- 

 low hairs in the emargination. (From de Sely's description).
