K i r s t ante n n a: — Tliis is nf tin- type ivjjrodiiccd liy ( '. Cl.Al s, 1891 a. Tlic lir.st 

 and sormul joints aiv only slightly separatrd. Tlio second joint has no l)ristl('s. The c-bristlc 

 is oharaotorizt'd liy the fact that it has ratluT numerous nioderatelv hmj,'. line hairs aionu' the 

 anterior side of it-s proximal tliird; it is not sword-shaped distally. There weie no yellow pi^inenl 

 corpusoles in liiis liinl) in the specimens investigated by me. Tliis antenna is hare. 



Second antenna: — Tlie p r o t o |i o d i t e is almost as well developed as 

 in the male. The proportion between the length ol the protopodite and tliat of the ex o p o- 

 il i t e is about the same as in the male. Endopodite: This has two joints; I did not 

 succeed in iliscovering any boundary between the original seooml and third joints. The type 

 is about the same as in C. Claus's pi. I, fig. 5, 1891 a and G, W. MOlleu's pi. 6, fig. 7, 

 1894. The a- and b-bristles have short hair . The g-bristle is about half as long as the proto- 

 ])odite, not or only slightly sword -.shaped distally and furnished with .sparse short hairs. The 

 f-, h-, i- and j-bristles are of somewhat diflterent lengths, about a third or a fifth shorter than 

 the g-bristle, bare and with scarcely perceptibl shafts; otherwise they are of the same type 

 as in the male. I was not able to discover any bristle between the h- and i-bristles. Pilosity: 

 The second endopodite joint is bare. 



Sixth limb: — Unlike what is the case in the male this is equipped with the normal 

 number of bristles for this genus. Exopodite: All the bristles on the first joint are relatively 

 short and weak; the dorso-lateral one especially is very much shortened; it is about as long as 

 or even somewhat shorter than the dorso-distal one. Some of the ventral bristles on this joint 

 often have short hairs; the dorso-lateral one has in most cases rather long hairs. 

 End joint: The dorsal claw and the ventral claw are often only about half as Igng as the 

 middle claw. 



Rod -shaped organ: (fig. 9) — This is of the type reproduced by the abov^e- 

 raentioned writers; it has two fine points distally and is bare; cf. p. 707 below. 



Synonyms. Remarks: — The species C. spinirostris described by C Claus, 1874 a and b is pre- 



sumably not a unit, as it is rather probable that the males and females grouped under this name 

 belong to different species. The descriptions and figures of both sexes are extremely incomplete 

 and do not permit of a quite certain identification of the sj^ecies. It was also with rather consid- 

 erable hesitation that I identified the form dealt wuth by me above with the male of this species 

 of Claus's. This identification is based chiefly on C. Claus's figure of the first antenna, pi. I, 

 fig. 8. With regard to this figure I wish to point out specially the length of the a-bristle and the 

 armature of the e-bristle; on the latter bristle we count ten rather strong, closely situated spines 

 (certainly = pairs of spines), proximally of which one considerably weaker spine is found. The 

 length of the shell stated by C. Claus, namely 1,2 — 1,4 mm., which may seem, of course, to 

 be evidence against this identification, presumably refers, like other statements in the diagnosis 

 (scarcely three fines in length!), to the female specimens. A comparison between C. Claus, 

 pi. I, fig. 1 and the figure 3 inserted here of the female shell should be enough to show with 

 aU desirable clearness that the females described by this author under this name 

 in the works mentioned do not belong to the species dealt with by me above; in C. Cl.AUS's
