Gen, 31. BradypOntiUS, Giesbr., 1895. 



Syn: Artotrogus, Brady (part). 



Generic Characters. Anterior division of body more or less expanded, 

 with the cephalic segment large and considerably produced at the postero-lateral 

 corners ; epimeral lappets of the trunk-segments well defined and successively 

 diminishing in size behind. Tail somewhat more produced than in the 3 pre- 

 ceding genera, with the genital segment moderately dilated. Anterior antenna) 

 more or less slender, and composed of a somewhat varying number of joints in the 

 different species. Posterior antennae of the usual structure. Siphon comparatively 

 slender, with the basal part somewhat thickened. Maxilla? with the lobes more 

 or less unequal. Maxillipeds comparatively slender. Natatory legs rather strongly 

 built; terminal joint of outer ramus in 1st pair with 3 spines outside and 3 seta) 

 inside; 4th pair with the inner ramus distinctly 3-articulate, though in most cases 

 rather feebly developed, with some of the setffi reduced. Last pair of legs some- 

 what less rudimentary than in the preceding genera, the free joint being provided 

 with 3 bristles, 2 apical and one lateral. 



Iti'iinti-/^. The chief character by which this genus is distinguished, as 

 compared with the 3 preceding ones, is the presence on the 4th pair of legs of 

 a distinctly 3-articulate inner ramus, which however in most cases is rather feebly 

 developed. Otherwise it exhibits on the whole a rather close relationship to the 

 typical genus Dytpontiit*. 4 species referable to the present genus will be described 

 below, and a 5th species has been recorded by Giesbrecht from the Bay of Naples 

 under the name of B. siphonatus.

V Bradypontius Canui, Giesbrodit. 



Specific Characters. Female. General form of body somewhat similar to 

 that in Dysponfms striatus, the anterior division being rather expanded, with the 

 greatest width almost equalling the length. Cephalic segment very large, occupying 

 about half the total length, and having the free edges evenly arched, postero- 

 lateral corners rather produced, frontal part rounded, without any dorsal crest. 

 Epimeral lappets of the 3 succeeding segments well defined and pointing obliquely 

 backwards; those of penultimate segment of same shape as the preceding ones, though
