Genus Monopia C. Claus.
Monopia, C. Claus, 1873. Eumonopia, C. Claus, 1891 h. Cypridina (part.), G. S. BUADY,
1865, 1897 and 1902a; G. W . Ml’LLRR, 1906b and 1912. Cypridinodes (part.), G. S. Brada 1902a.
Remarks: — This genus comprises according to my opinion (cf. above pp. 193) two
sub-genera:
Monopia C. Cl.A RS
Cypridinodes G. S. Brada.
It may probably not be convenient to work out a diagnosis of this genus before a detailed 1
re-examination of C. Claus’ Monopia flaveola — the only representative hitherto known of one "
of the two sub-genera mentioned — has been carried out. 1 have, consequentlv, confined. myself
in this treatise to an élaboration of a description of Cypridinodes, the only one of these two
sub-genera of which I have had material myself. A conséquence of this is that severa! of the
characters in this description are of generic and not of sub-generic value.
Sub-genus Cypridinodes G. S. Bradv.
Cypridina (part.), G. S. Brada, 1865 and 1897; G. \Y. MÜLLKR, 1906 b and 1912.
Cypridinodes, G. S. BRADA, 1902 a.
Description: — Shell: — The shape is somewhat oval with a well-developed posterior
corner. The rostral incisur is rather deep and narrow (G. S. BRADA’s figure of C. fa vus, 1902 a,
pl. XXII, fig. 20, is in this respect, as in several others, quite incorrect, a faet that I vérifiée!
when re-examining the type specimen). Near the inner margin of the incisur there are two
medial bristles situated close to each other. Posteriorly the list runs in an unbroken line straight
across the posterior part of the shell (I have not succeeded in finding the place where it passes
into the list along the ventral margin of the shell). With very strong calcification. The forms
hitherto known are comparatively large.
First antenna: — This is long, siender and has eight joints. The sensory bristle
of the fifth joint has thirteen sensory filaments. Bristle b and c in the males are modified in
the way described for the sub-genus Doloria. The distal bristles are not mueh longer in the
males than in the females.
Second antenna: — The protopodite has a medial-distal bristle.
Exo-p o d i te : The bristle of the second joint is powerfully developed. The natatory bristles on
the fhird to the ninth joints are quite without spines. The second to the ninth joints have basal
spines. Endopodite: This is similar in males and females and is comparatively well
developed, elongated; the bristle of the end joint is relativelv long.
M a n d i b 1 e: — Protopodite: The endite on the coxale is either simple distally
or has only a faint indication of bifurcation; its spines are rather powerful, especially those
