■vellow — not'Ml liy that author as occurring among his specimens may indicate di-tinct 

 species, 1 am myself scarcely disposed to accept that view, for among the specimens 

 here described there are many green ones, although tlie bulk are of the brcnvnish 

 colour so well described and figured by Professor Sars. 



Genus Cyprinotus G. S. Brady. 



Cyprinotus dentato-marginatus (Baird). (Plate XXIII. figs. 6, 7.) 



Specimens apparently referable to this species were collected by Dr. Meinert at Bona, 

 Algiers. I give a figure of one of these. It differs somewhat from Dr. Baird's figure, 

 being rather more elongated, but has proportions similar to those figured by Prof. G. 

 O. Sars in his paper on " Ostracoda and Copepoda raised from dried Australian mud." 

 Dr. Baird's specimens were from Nagpur, India. 



Cypri.votus fragilis, sp. nov. (Plate XXIII. fig^. 9, 10; Plate XXV. figs. 37-39.) 



Shell, seen from the side (PL XXV. fig. 37), very closely similar in outline to 

 C. jyrnsina Fischer, but entirely without surface-markings : seen from above (fig. 38) 

 the posterior extremity is broader and more rounded, the anterior not so distinctly 

 produced or sinuated ; it is also wider in proportion to the length. Shell very thin 

 and fragile, colourless. Length 1'5 mm. 



I figure here some of the soft parts of the animal (PI. XXIII. figs. 9, 10), which do 

 not differ from those of the foregoing species. 



Hah. Biskra, North Africa; females only [Dr. Meinert). 



Genus Candonopsis Vavra ^. 



Antennae destitute of swimming-setae. Mandibles and maxillae with much elongated 

 palps. Maxillipeds (second pair of maxillae) with a rudimentary branchial plate bearing 

 three or more plumose setae. Posterior margins of the caudal rami without setae. 



Vavra's definition of this genus gives the '• fan-plate " of the maxillipeds as bearing 

 only three plumose setae. None of the few specimens of C. comptanata which I have 

 dissected have had these limbs in a perfect condition, but the remains of at least five 

 setae were plainly visible in one of them. Inasmuch as in other respects the animals 

 agree with the typical CandonojJsis, it becomes necessary to modify the definition so far 

 as regards the number of setae.

Candonopsis complanata, sp. nov. (Plate XXV. figs. 30-36.) 



Shell, seen from the side, elongated, subreniform, more than twice as long as broad 

 (fig. 30), extremities rounded, equal, dorsal margin forming a flattened curve, almost
