292 MR. G. S. BRADY ON EUROPEAN CYPRIDINID.E. [Apr. 4, 



and third joints long, the second much shorter, the rest short and 

 subequal : secondary branch in female indistinctly jointed, setose ; 

 in the male long, three-jointed, cheliform. Mandibular feet nearly 

 alike in both sexes ; in the female armed, as in the female Brady- 

 cinetus, with mandibuliform processes and spines, in the male bearing 

 on the basal joint a small tubercle with two short hairs ; second pair 

 of jaws in the female armed with mandibuliform processes. Eyes as 

 in Bradycinetus. 



Asterofe* (Philippi). 



Shell subcylindrical, beak not at all produced. Upper antennas 

 as in the preceding genus. Second joint of the natatory branch of 

 the lower antennae in the male elongated, in the female scarcely 

 longer than the succeeding joints ; secondary branch in the male 

 robust, subchelate ; terminal joint slender, curved upwards ; in the 

 female simple, Particulate, last joint setiform. First maxilla con- 

 sisting of a broad subquadrate or crescentic lamina, densely clothed 

 on its distal margin with long bristles ; second swollen at the base, 

 narrowed at the apex, where it bears six plumose setae, basal portion 

 setose along its convex margin ; third maxilla narrow, elongated, 

 setose along the inner margin. Abdominal laminae broad and short, 

 subtruncate at the extremity.

Asterope grcenlandica, <3 , Fischer, 1854. 



Two specimens of a form exactly conforming to Fischer's descrip- 

 tion of Asterope grcenlandica occurred in M. de Folin's dredgings 

 from the Fosse de Cap Breton. The shell differs from that of the 

 female B. brenda in being less tumid and slightly more angular in 

 outline ; it is also quite smooth and free from villosity. The swimming- 

 filaments of the upper antennae are a little longer than those of the 

 female, and more decidedly plumose. There is also a stout auditory 

 seta ; the natatory branch of the lower antenna is nearly alike in 

 both sexes, but the secondary branch in the male is largely deve- 

 loped and triarticulate. The mandibular foot is much elongated 

 (Plate XXVI. fig. 6), and bears on its basal portion a large and strong 



* This genus might perhaps with more propriety (on account of the widely 

 different structure of the maxillae) be made the type of a distinct family. It is 

 identical with Cylindroleberis (Brady), a fact of which I was not aware when 

 that name was proposed.
