 there are two rather hmg bristles, the anterior one ol' which is somewhat longer tlian the other-; 

 both, espeeiallv the longer one. furnisheil with cU)se, k)ng. line hairs. Distally-posteriorly this 

 joint has three or four liristles. oiw rather long and powerful and very strongly pectinated, the 

 others somewhat different from each other in length and about half as long as the i'ornier bristle 

 or somewhat shorter, rather weak, bare oi- with short, weak secondary teeth. The end joint 

 is rather strongly chitinized and is usually furnished with thirteen bristles, in exceptional cases 

 a somewhat larger number being found: l''oiir a -bristles (exceptionallx five were found) of 

 moderate lengths and strength, bare ov furnished sparsely with short, fine secondary bristles. 

 Three b-bristles, the anterior one of which is rather powerful, of moderate length and very strongly 

 pectinated; the two others are subequal and somewliat shorter and weaker, the anterior of them 

 rather strongly pectinated distally, the other furnished distally with rather few, but very 

 powerful secondary teeth. Three c-bristles (four c-bristles were found on the maxilla of one 

 side in onlv one specimen), the two posterior of which have about the same type and size as the 

 anterior b-bristle, the anterior one being quite short and weak, in most cases armed with a few 

 secondary teeth. Three d-bristles, somewhat more powerful than the other bristles of this 

 joint, of moderate lengths, the posterior one somewdiat longer than the others. The posterior 

 d-bristle is of about the same type as the anterior b-bristle, the two others are armed at the 

 middle with a moderate number of very powerful secondary teeth. The bristles of this joint 

 all varied somewhat with regard, to the shape and number of the secondary teeth. Pilositv: 

 < In the first endopodite joint there are transverse rows of short, fine hairs. 



Fifth limb: — Protopodite: The first endite (fig. 19) has eight bristles, all 

 of the same type, powerful masticatory bristles, furnished with exceedingly numerous long, 

 powerful secondary bristles, arranged in more or less distinct wreaths. Of these bristles 

 nos. 2, 4, 6, 7 and 8, counting from the anterior side of the limb, are of moderate lengths ; the 

 two first-mentioned ones are subequal and somewhat longer than the three others, which are 

 also subequal. Bristles nos. 1, 3 and 5 are rather considerably shorter than the five mentioned 

 above. In one specimen nine bristles were observed on this endite on the fifth limb of 

 both sides, the extra bristle being situated close to bristle no. 5 and being somewhat shorter 

 than this bristle. The five inner bristles of the second endite (fig. 20) are powerful and of 

 moderate lengths, the anterior and the posterior ones being somewhat longer and more powerful 

 than the others; tbey are all furnished with one or a few wreaths of long, powerful secondary 

 bristles. Nos. 1 and 2, counting from the anterior side of the limb, are furnished distally with 

 a few rather powerful secondary teeth, no. 3 is finely serrated distally, nos. 4 and 5, especially 

 the latter, are strongly pectinated distally. The single bristle on the anterior side of this process 

 is short, somewhat varying in length, often furnished with short hairs, sometimes with a few 

 long secondary bristles. The seven bristles of the third endite (fig. 21)are all powerful, especially the 

 posterior one, and of moderate lengths, nos. 4, 5 and 6, counting from the anterior side of the 

 limb, being somewhat shorter than the others. All except the three last-mentioned ones are 

 furnished at the middle with one or a few irregular wreaths of long, pow^erful secondary bristles.
