rathor small and has a rather small bristle with a thick haso {f^oc tho arr(impanvin<i; fig. 11). 

 E n d o p o d i t e: The first joint lias four short-haired bristles on the posterior sich'; these are 

 of about the same relative lengths as in my fig. 22 of C. symmetrica. The antero-distal bristle 

 on this joint has short hairs and is not inconsiderably longer th.in the sccoiul iri(|(i|i(i(litc jdiiil. 



Maxilla: - P r o t o p o d i t e: Kndite on tlie pnico.xalc: The ihicc pd.stcro-mitcr 

 tube-bristles and the pointed bristle situated close to them are furnished witii a lew moderately 

 long secondary bristles. The four other single-pointed bristles are furnished with rather long 

 spines, the two anterior inner ones (like the anterior inner tube-bristle) have rather long secon- 

 ilary bristles as well. (The difference between ,, secondary bristles" and ,, spines" is of course 

 not a fundamental one, but only one of degree; the , .spines" are more or less strongei' tliaii tlie 

 ,, secondary bristles".) Endite on the coxale: There are only three, not, as is usual in this genus, 

 four tube-bristles on the posterior process. Endopodite: First joint: On one maxilla 

 in the specimen investigated by me there were three bristles on the posterior edge (as is usual 

 in this genus), on the other there were four. The end joint is relatively short and of about the 

 same type as in my fig. 9 of C. serrulata. 



Fifth limb: — P r o t o p o d i t e: The longer of the two tube-bristles on the 

 second endite has short hairs. E n d o j) o d i t e: This is of the same type as has been described 

 for C. oblonga (see my fig. 27 of C. symmetrica). E x o p o d i t e: First joint: This has one or 

 two medio-ventral short-haired bristles, three proximo-ventral bristles, the two longest of which 

 are furnished with rather long secondary bristles, the third having short hairs, two disto-ventral 

 bristles, one of which is furnished with rather long secondary bristles. The dorso-lateral bristle 

 on this joint is furnished with rather long secondary bristles. All the bristles on this joint are 

 of about the same relative length as in my fig. 27 of C. symmetrica. Of the bristles on the end 

 joint the dorsal one and the ventral one are subequal, someAvhat more than half the length of 

 the middle one. Pilosity: The protopodite and the first exopodite joint are partly furnished 

 with long hairs. 



Sixth limb: — Exopodite: First joint: The dorso-distal bristle is relatively 

 somewhat longer, the dorso-lateral bristle relatively somewhat shorter than in my fig. 30 of 

 C. symmetrica. On one limb one of the three ventero-distal bristles of this joint liad short hairs 

 in the specimen investigated by me. 



Seventh limb: — The end joint is furnished with spines. 



Furca: — Behind the claws there is no unpaired bristle. 



Rod-shaped organ: — This is of the same type as in C. Haddoni and C. 

 bispinosa; cf. the accompanying fig. 3. 



Upper lip: — This is of about the same type as in the two species just mentioned, 

 but the part between the combs is perhaps somewhat more deeply notched (not so much, however, 

 as in my fig. 15 of C. rotundata) and the teeth of the combs are somewhat coarser. The 

 paragnates are similar to those of the species just mentioned. 



Identification. Remark: — It seems to me extremely probable that the female described above really 



belongs to this species, partly because of the great similarity that is shown in the type and size
