as ill pi. XXVIII, lig. 42, G. W. Mt'LLER, 1890 a (cf. the accompanying fig. 3), i. e. of the same 

 elongated type as that of the male, but with the posterior part of the shell dominating somewhat 

 more over the anterior part. In other respects it was about the same as that of the male. 

 First antenna: — This is relatively short with a scarcely perceptible boundary 

 between the first and second joints. The second joint has no bristle. The e-bristle is about 

 one and a half or twice as long as this limb; distally on the proximal third of its anterior side 



it has rather sparse, short, fine luiirs; it is 

 not sword-shaped distally. The a-, b-, c- 

 and d-bristles are subecpial and about 

 half as long as the e-bristle. There are 

 yellowish-brown pigment corpuscles, at 

 least in some cases, in the proximal part 

 of tliis limb. All the joints are bare. 

 Second a n t e n n a : — The 

 p r o t o p o d i t e is only slightly weaker 

 than in the male. The proportion bet- 

 ween the length of the protopodite and 

 that of the exopodite is about the 

 same as in the male. E n d o p o d i t e: 

 This has two joints, the original boundary 

 between the second and third joint having 

 ([uite disappeared. The f-, g-, h-, i- and 

 j -bristles are sube([ual and are about as long as or somewhat longer tliaii half the length of 

 the protopodite; they are all bare and without any shafts. There is an extremely small 

 papilla (scarcely perceptible with Reichert's ocular 4 and Leitz's immersion V12) between 

 the h- and i-bristles. One of the c- and d-bristles is develojjed, at least in some cases; it is 

 very short, cmly about as long as the proximal width of, for instance, the f-liristle (is tliis 

 bristle's absence secondary?). Pilosity: The second endopodite joint is bare. 



Sixth limb: — Endopodite: One of the two bristles is in most cases furnished 

 with short hairs. Exopodite: The first joint has no dorso-distal bristle ; the other bristles vary 

 somewhat in length; they are often of the same relative lengths as in my fig. 30 of C. symmetrica. 

 R o d - s h a p e d organ: — The point of the shaft reaches about as far in front of 

 the point of the first antenna as the length of the capitulum. The capitulum is somewhat 

 more than half the length of the first antenna; it varies in shape; it was found to be of about 

 the same types as are drawn by G. W. Muller, 1906 a, pi. XMI, figs. 30—33.
