Palpi short, broad at the base, conical: a tuft of bristles at the apex, a few short hairs on 

 the interior margin. 



Mandibles with three teeth and the inferior angle pectinated; tooth i and 2 twice as 

 far from one another as tooth 2 and 3; distance between 3 and inferior angle still smaller. 

 Surface of mandible covered with delicate hairs in groups of two or three on the part near 

 the toothed edge. Short hairs along the inferior margin. 



Maxillae with a distinct notch slightly above the middle of the edge. Above the 

 notch the edge bears three strong and a smaller spine; beneath the notch the edge is straight 

 and is furnished with seven or eight spines of nearly equal size. Surface near the edge covered 

 with hairs: superior margin furnished with a few hairs in the neighbourhood of the first spine, 

 inferior margin with a row of numerous hairs. 



Outer maxillae have the inner surface rounded with numerous bristles, which can 

 hardly be said to be divided into two different groups; opening communicating with the body- 

 cavitv at the end of a very long and flattened projection, cut off transversely at the extremity. 



Cirri. First pair at a little distance from the second, short, with unequal rami, 

 shorter ramus flat with eight segments which are oblong in transverse direction; segments much 

 flattened towards the inner margin where each is furnished with a row of five or six strong 

 spines; longer ramus with 9 segments, of a more cylindrical shape, furnished with a row of five 

 to six spines along the outer as well as along the inner margin. Both rami thickly clothed 

 with longer hairs. 



Second cirrus shorter than the following. Anterior ramus with seventeen, posterior 

 with eio-hteen segments. First segment long, segments 2 — 8 nearly quadrilateral, segments 9 and 

 followino- ones becoming more and more elongate, last segments very long and narrow. Each 

 seo-ment has about four pairs of bristles along the anterior margin, a few hairs along the 

 posterior margin and also one or two longer hairs at the extremity of each segment. 



Sixth cirrus rather long with about twenty-four segments in each ramus. Basal segment 

 long, cylindrical, segments 2 — 6 quadrilateral, 7 and following ones growing gradually longer 

 and more slender. As a rule the segments are furnished with four pairs of spines along the 

 anterior margin and a single spine (or no spine) at the posterior margin near the extremity. 



Caudal appendages have six segments. They are very slender, and reach with their 

 last segment only slightly beyond the pedicel of the 6'^ cirrus. Very long and delicate hairs are 

 planted at the extremity of the second to sixth segments. The extremity of the last segment is 

 furnished with half a dozen hairs, two of which are longer than twice the length of the segment. 



No penis. 



Male. I found two males on the one, three on the other side of one of the females. 

 They are attached to the inner side of the scutum, near the occludent margin, in a duplicature 

 of the sac or mantle, slightly in front of the adductor muscle. They have the ordinary long 

 oval shape and show no trace of valves. Their size is about 0,84 X 0,42 mm. Their surface is 

 clothed with very short hairs or spines, which stand alone or in groups of two or three without 

 forming regular rows. Slightly longer hairs form a little tuft on each side of the opening giving 

 entrance to the interior of the sac. The prehensile antennae have the ordinary shape : a longer
