joint, the other is about twice as long as this. The two others of the bristles mentioned are sub- 

 equal and about as long as the shorter distal bristle. All four are of about the same type, with 

 a wreath of long, stiff secondary bristles at the middle and exceedingly fine, short hairs distaUy. 

 Exopodite: The distal bristle is most frequently about the same length as this branch, 

 the other is rather slightly shorter; either they both have a wreath of long, stiff secondary 

 bristles at the middle and exceedingly fine, short hairs distally or else one of them has no wreath 

 of bristles. E n d o p o d i t e: First joint: Three of the four ventral bristles are long and have 

 a few wreaths of long, stiff secondary bristles at the middle and fine, short hairs distally; the 

 fourth is usually only about a third of the length of these three and has one wreath of long secon- 

 dary bristles at the middle and short, fine hairs distaUy. (The proportions of these bristles are 

 about the same as in fig. 11 of Ph. (Ph.) LiUjeborgi). Second joint: The proximal group of 

 bristles on the anterior side most frequently number three, sometimes four; these are somewhat 

 different in length, the longest being from a third to a half the length of the anterior side of this 

 joint; they all usually have exceedingly fine, short hairs; sometimes, however, some of them 

 may have some long secondary bristles at the middle. Between this group of bristles and the 

 distal anterior group there is on the medial side one bristle (on one mandible of one specimen 

 two bristles) of the same length as the bristles in the proximal group, but with somewhat coarser 

 short hairs (about the same as in fig. 11 of Pli. (Ph.) LiUjeborgi). End joint: The longest middle 

 claw is about as long as the second endopodite joint; the anterior claw is scarcely half this length. 

 Pilosity: The second protopodite joint and the second endopodite joint have groups of short, 

 stiff hairs on the inside. 



Maxilla: — Protopodite: First endite: This has ten bristles distaUy. The 

 two inner ones of these are subequal, of moderate length and strength, furnished at the middle 

 with one or two oblique wreaths of long, stiff secondary bristles and fairly strongly pectinated 

 distally. Four bristles of about the same strength and length as the preceding ones — their 

 length and strength varies, however, to some extent — usually have one, sometimes two, wreaths 

 of long, stiff secondary bristles at the middle, and rather powerful secondary teeth, often 

 rather few in number, distally; the number of these secondary teeth varies, however, rather 

 greatly. Three of them, one situated just outside the two first-mentioned ones, one at the outside 

 of all the other bristles of this process and one about half-way between the two others, are 

 somewhat shorter and weaker than the six already described; they usually have a wreath of 

 long, stiff secondary bristles at the middle and are rather strongly pectinated distally; some- 

 times their distal secondary bristles are also rather long. The remaining bristle is situated 

 almost opposite the middle one of the three bristles just mentioned and is very short and rather 

 weak; sometimes it has short hairs and sometimes a wreath of long, stiff secondary bristles at 

 the middle (see fig. 12 of Ph. (Scl.) Affellofi). Second endite: This has six distal bristles of 

 moderate length; sometimes all these are subequal, often one of the anterior or the posterior 

 ones is somewhat shorter than the others. The two middle ones are powerful, considerably 

 more so than the others, and are furnished distally with a somewhat varying number of strong 

 secondary teeth ; the four others with a moderately strong pectination distally. All six usually 

 have a wreath of Ibng, stiff secondary bristles at the middle (sec fig. 13 of Ph. (Scl.) Appellofi).
