number of fine, rnthor floxiblo, long, sparse hairs; no. 7 is of iil)ou( the same type as no. 1, l)\it 

 somewliat stronger. Of the tive inner bri.stles of the seconil endite (fig. 13) the two anterior 

 ones are rather strong, subequal, moderately long and both of the same type; they are rather 

 strongly pectinated distally and may or may not have a wreath of rather long, stiff secondary 

 bristles proximally of the miiUlle. The posterior bristle is of the same type as the former ones 

 but is considerably more powerful. Of the two middle bristles, both somewhat shorter than the 

 former ones, the anterior is finely serrate distally and has no long secondary bristles; the posterior 

 one. which is the shortest, has in the middle a wreath of long secondary bristles, distally it is 

 smooth or perhaps with a few exceedingly weak secondary teeth. The remaining bristle on 

 this endite. situated on the anterior side of the process, a short distance from the five former 

 ones, is very short and bare. Of the seven bristles of the third endite (fig. 14) the two anterior 

 ones and the posterior one have the same type and about the same size as the corresponding 

 bristles on the second endite, nos. 3 and 4, counting from the anterior side of the limb, agree 

 with no. 3 on the process mentioned, no. 5 is quite short and bare or has a few long and 

 rather soft hairs, no. 6 is moderately long and strong and has short, fine hairs. The distal 

 spine of the protopodite is unusually long and powerful. The e p i j:) o d i t e has from 55 

 to 60 bristles, all furnished with long hairs right to the point. Tlic c x o p o d i t e has four 

 joints: First joint: The main tooth (fig. 15) has seven constituent teeth all well defined proximally; 

 the secondary teeth on the latter of about the same type as is shown in the adjoining figure, 

 but vary, however, to some extent. The bristle close to the main tooth on the posterior side 

 of the joint resembles in type and size the posterior bristle on the third endite. On the anterior 

 side of this joint there are four bristles, three of which are situated close together in a row near 

 the main tooth, the other one a short distance from these, farther out on the joint; two of the 

 three former ones are sube(iual and rather long and strong (about the same as is shown in the 

 figure 22 of C. (Vargula) norregica), the third is somewhat shorter; one of the two long ones is 

 rather strongly pectinated distally, the other has exceedingly fine, short hairs distally, both 

 have stiff, long hairs in the middle; the short one has long, stiff hairs in the middle, short hairs 

 distally, almost bare. The outer one of this joint's bristles is somewhat shorter than the two 

 longer of the former bristles and has long, soft hairs along the greater part of its length, short, 

 fine ones distally. Second exopodite joint: This has four powerful a-bristles with numerous 

 moderately powerful secondary teeth continuing almost to the points of the bristles; in addition 

 this joint has eight b-bristles, one c- and one d-bristle; the two latter are somewhat shorter 

 than the longest b-bristles and have rather close, long, soft hairs at the middle and short hairs distally. 

 The outer and iimer lobes of the third exopodite joint are well developed (fig. 16); the outer one 

 somewhat larger than the inner one. Bach of these lobes has two subequal bristles of moderate 

 length, with long, fine hairs at the middle and short, fine hairs distally. The end joint (fig. 16) 

 is about the same size as the outer lobe of the preceding joint and is furnished with two 

 bristles of the same t}'pe and size as the bristles on this joint. Pilosity: The outer lobe of the 

 third exopodite joint and the end joint are partly provided with close, soft, fine, long hairs. 

 Sixth limb (fig. 17): — Protopodite: The first endite has two or three 

 rather long and strong distal bristles, two of which usually have a few oblique wreaths of long.
