* The general foim of this species [Cythere fovcolata] is very familiar ; many might he named which approach it 

 rather closely, but no described species seems to be absolutely identical with it. The nearest, perhaps, are Cythere 

 borealis, Brady— an Arctic form,— and Cythere mlkhilus, Brady, a fossil of the Antwerp Crag. — (Brady, Zool. Chall. 

 Jixp., part 4, p. 76.) 



- Seen on the dorsal surface, this species [Cythere kerguelenensis] bears a close resemblance to the common British 

 Cythere alboniacnlata, Baird, but the shell is much more coarsely sculptured, while the spinous margins and very 

 broadly reniform lateral outline are constant distinctive characters. — (Beady, Zool. Chall. Exp., 2'art 4, p. 79.) 



2 A few detached valves brought by the Challenger from off Prince Edward Island in the Southern Ocean are in 

 no respect distinguishable from the fossil specimens described by me in a Monograph of the Fossil Ostracoda of the 

 Antwerp Crag, under the name Cythere polytrcma. It is extremely interesting to note the occurrence, alive in this 

 ilistant region, of so well marked a European fossil. — (Brady, Zool. Chall. Exp., part 4, p. 87.) 



* Tliough bearing considerable resemblance to the northern species Cytheropteron lalisdmuui (Norman), tliis 

 [Cytlieropteroii assimile] is easily distinguished by the character of the surface-sculpture, which shows no tendency to 

 run into tran.sverse grooves ; the lateral ahe, loo, are considerably more prominent. — (Brady, Zool. Chall. Exp., part 4, 

 p. 139.) 



* Cytlieropteroii Kaphoidx is not unlike in general character to Cytheropteron subcircinatam, Sars, but is vei'y much 

 le.ss tumid.— (Brady, Zool. Chall. Exp., part 4, p. 1.36.) 



" The nearest known ally [of Cijlherura lilljchoryi] is probably Cytherara dathrata, Sars, with which it closely 

 agrees in style of surface-sculpture though quite different in proportions and general contour. — (Brady, Zool. Chall. 

 Exp., part 4, p. 133.)
