 a short distaiuo jtroxiiiuilly of tlu' two postorior luoro or less bristle-like appeiuluges of this 

 |>rofoss, tlie third is situated near the anterior ed<je of the proeess, a short distaniie proxiinall\' 

 of the bristle on the anterii)r od<ie. Thetwo former of those bristles are most frecpiently subtMjual 

 and about as long as the breadth of the endite distally; the two anterim ones vary somewliat 

 in length, and are usually two or three times as long as the two posterior ones. Distally on tlic 

 inside on this joint there is a single bristle, about as long as or somewhat shorter than the iirst 

 endopodite joint. All these five bristles have short, fine hairs. There is no epipodial 

 a p p e n d a g e. 'I'lu' e x o p o d i t e is represented only by one bristle, situated sonu^what 

 laterally. This bristle, which is most frequently about as long as or somewliat longer than the 

 anterior side of the first endopodite joint, is, contrary to the rule in this sub-family, 

 sometimes furnished with short, fine hairs or quite bare. Endopodite (fig. 17): The antero- 

 distal bristle of the first joint is about as long as or somewhat longer than the anterior side of 

 the following joint. On the posterior side the first joint has four bristles; of these the lateral 

 one is rather powerful and long, almost as long as the endopodite; of the three others two arc 

 about as long as the height of this joint, the third is about twice or not quite twice as long. 

 Second joint: The three antero-distal bristles are of somewhat different lengths, the longest 

 being about as long as or somewhat shorter than twice the length of the third endopodite joint, 

 the shortest about as long as this joint. The two posterior bristles of this joint are most fre- 

 quently subequal and are almost as long as the longest posterior bristle on the preceding joint. 

 End joint: Of the seven bristles four are in most cases subequal, being most frequently somewhat 

 longer than the anterior side of the two distal joints; one, the most anterior, is of about the same 

 strength as the four former ones, but in most cases it is about a third shorter than these; the 

 two remaining ones, situated postero-medially on the joint, are considerably weaker than the 

 former bristles and about as long as or only rather slightly longer than the end joint. All the 

 bristles on the endopodite have short, fine hairs. Pilosity: Besides the groups of hairs posteriorly 

 on the endite the basale often seems to be also hairy distally on the inside, sometimes even 

 on the anterior side of the endite. The first and second endopodite joints are bare. 



Maxilla: — Protopodite: The endite on the procoxale (fig. 13, ^J = $), is 

 furnished with only six bristles. Two of these, the antero-inner and the postero-outer ones, 

 are of the tube-bristle type. The former of these is moderately long, rather powerful and provided 

 distally of the middle with an oblique wreath of long, stiff secondary bristles. The other, which 

 is attached somewhat proximaUy of the rest, is rather considerably shorter and weaker than the 

 antero-inner one and has short, fine hairs or is almost bare. The four remaining bristles on this 

 endite are rather powerful, finely pectinated or almost bare and of moderate and somewhat 

 different lengths. (The proportions of these bristles are often the same as in the accompanying 

 figure.) The endite on the coxale (fig. 14, <5 ^ ?) has twelve bristles, seven of which are situated 

 on the posterior and five on the anterior process. Of the seven former ones the postero-inner 

 one, which is situated a short distance proximaUy of the others, is rather powerful, moderately 

 long, pointed and moderately strongly pectinated. The most anterior one is in most cases of 

 about the same length, strength and type as the former one, but its pectination varies. Of the
