stiff secondary bristles, the third, in most cases, with short hairs distally and two short, plumous 

 medial bristles. Second endite: This has two rather long and powerful subequal distal bristles 

 and two or three short, plumous medial bristles. Third endite: This has three rather long and 

 powerful distal bristles of which the middle one is somewhat shorter than the two others, and 

 one medial bristle, of about the same length and type as the long distal bristles. The distal 

 bristles on the second and third endites are of the same type, with a wreath of long and rather 

 stiff secondary bristles at the middle and short hairs distally. The epipodial appen- 

 dage of the protopodite is represented l)y four rather short bristles, either with short hairs 

 or bare, issuing from a small, lobe-like process. E x o p o d i t e: The endite of the first joint 

 has three or four, usually three, rather long and powerful distal bristles; of these the middle 

 one is somewhat longer than the others and of the same type as the distal bristles on the 

 preceding endite; the ventral one has short hairs, the dorsal one (or the two dorsal ones) usually 

 also with short hairs, sometimes, however with long hairs in the middle. In addition this endite 

 has one medial bristle of the same type and length as that on the preceding endite. Second 

 joint: This has a rather large number of bristle. Eleven or thirteen of these bristles are of 

 moderate length or rather long, all situated very near to the ventral edge; the two posterior 

 ones of them with dense long, soft hairs right to the point, the others with long hairs at the 

 middle and short hairs distally; the long hairs of the last-mentioned bristles are soft on the 

 posterior ones, on the anterior ones they are somewhat more stiff, though only slightly so, and 

 they are not arranged in distinct wreaths. Four or five bristles havQ short hairs and are generally 

 considerably shorter than the former; some of these are somewhat, though only slightly, 

 displaced from the ventral edge of the joint up the lateral side. There is no pronounced 

 gap between the posterior ones of the bristles of this joint and the others. Pilosity: On the 

 inside this limb has rather close, short, stiff hairs; laterally along the ventral edge -of the 

 second exopodite joint there is also a series of short, stiff hairs. 



Seventh limb (fig. 18): — This is comparatively short, attaining only half the 

 length of the shell. Distally there are ten or eleven (usually ten) ventral and seven or eight 

 (usually seven) dorsal cleaning bristles, placed very close together. Of these bristles, both in the 

 case of the dorsal and ventral ones, the most distal one is rather short or of moderate length; 

 the next distal one, on the other hand, is comparatively long; starting from this latter bristle 

 these bristles decrease fairly uniformly in length the more proximally they are fixed, though 

 one or two may not follow this rule; the proximal ones are rather short. Proximally of these 

 bristles there are eleven or twelve (usually eleven) ventral bristles and from nine to thirteen 

 dorsal ones scattered irregularly along the distal half of the limb; these bristles are generally 

 subequal and moderately long; tlieir length is, however, somewhat variable. The cleaning 

 bristles arc furnished with from three to six bells, transversely cut off distally; (the very short, 

 ventero-proximal cleaning bristle on this limb of the type-specimen, see fig. 18, which was furnished 

 with only a single bell, was apparently pathological); the tongue of t\w tli.stal bell is cut off very 

 obli(|uely [type about the same as is :-;ho\vn in fig. 28 of C. ( Macrocypridina) castanea]; proximally 

 of the bells the cleaning bristles arc perfectly smooth. The end comb (fig. 19) consists of from 

 seven to ten distal teeth and of three or four proximal teeth on both sides of these. The distal
