Group 1. Paracyprides. 



Remarks. To this group I provisionally refer the 4 following genera: 

 Paracypris G. O. Sars, Aglaia Brady, Paracypria G. O. Sars, and Phlyctenophora 

 Brady. These 4 genera seem to agree pretty well in the structure of the genital 

 apparatus, as also on the whole in that of the limbs, and exhibit some relations 

 to the next 2 groups, Candonides and Cyclocy prides, though being scarcely 

 referable to either of them. Only the 1st of these genera is represented in 

 the Fauna of Norway. 



Gen. 8. Paracypris, G. O. Sars, 1865 



Generic Characters. Shell elongate compressed, narrowly produced behind, 

 and of rather firm consistency, with the edges highly chitinised. Eye well 

 developed. Antennae not adapted for swimming; the anterior ones slender, 

 but with the setae of the terminal part comparatively short. Posterior antennae 

 without any trace of natatory setae, sensory appendage of the 1st terminal joint 

 pronouncedly club-shaped; apical claws moderately slender. Anterior lip only 

 slightly prominent. Mandibles of quite normal structure. Maxillae with the 

 masticatory lobes narrowly produced, palp likewise narrow, with the apical 

 joint longer than broad. Maxillipeds provided at the base with a small, but 

 well defined vibratory lamella, palp (in female) simple; sub-linear in shape. 

 Both pairs of legs much elongated and only slightly differing in structure, each 

 carrying on the tip a long curved claw; the posterior ones, however, more 

 recurved, and having on the tip 2 unequal bristles in addition to the claw, the 

 one abruptly reflexed. Caudal rami rather fully developed, and resembling 

 somewhat in shape those in the genus Candona, though having 2 setae on 

 the dorsal edge. 



Remarks. This genus was established in the year 1865 by the present 

 author, to include a Cyprid, which, on a closer examination, was found to 

 approach the typical freshwater forms more closely than any of the other ma- 

 rine Cypridae observed; hence the generic name proposed. Indeed, the structure 

 of the posterior antennae and in particular that of the maxillipeds clearly proves 

 it to be referable to the subfamily Cyprince, as here defined. The genus Aglaia 

 of Brady seems to be very nearly related to the one here in question, though 

 differing rather conspicuously in the shape of the shell. A single species only 

 of the present genus is as yet known to me.
