distinctly denticulated and only curved in their outer part, the longer claw 

 considerably exceeding half the length of the ramus, dorsal seta of moderate 

 size. Genital lobes simply rounded off behind. 



Male of about same size as female, but slightly differing in the shape of 

 the shell, the posterior part of which is comparatively higher and more broadly 

 rounded off. Posterior antennae exhibiting the usual well-marked subdivision 

 of the penultimate joint and the characteristic sensory spines at the junction of 

 the 2 joints. Prehensile palps of the maxillipeds somewhat unequal, the right 

 one being conspicuously broader than the left and angularly bent at the end; 

 dactylar part of both palps terminating in a sharp point. Copulative appendages 

 provided behind with 2 well defined thin lobes of nearly equal size, the upper 

 one somewhat securiform in shape, the lower broadly rounded. 



Colour in both sexes opaque white. 



Length of adult female amounting to 1.25 mm. 



Remarks. This form was described in the year 1890 by the present author, 

 and was at that time identified with Cypris pubescens of Koch. Subsequently 

 however Hartwig found the true Kochian species, and stated its difference from 

 the present species, which he proposed to rename as above. Yet, Dr. Kaufmann, 

 though admitting the specific difference of the 2 forms, has found it permissible 

 to employ for the present species the Kochian denomination with only the 

 necessary change of the authors name, as he is of opinion, that the form 

 recorded by Koch does not at all belong to Candona, but to a particular 

 genus, Pseudocandona. The validity of this new genus seems however to me 

 to be very questionable, the only difference from Candona being the supposed 

 want of a subdivision of the penultimate joint of the posterior antennae in the 

 male. In any case the name pubescens cannot in my opinion be employed 

 to both these species, but must evidently be restricted to that originally recorded 

 by Koch. 



Occurrence. The only place where I have met with this form is in a small 

 waterhole in the immediate neighbourhood of Christiania, from which sever 

 specimens, males and females, were collected, many years ago, and late in t 

 autumn. This water-hole is now filled up and, like many others of my best 

 finding-places, destroyed by new-building. 



Distribution. British Isles (Brady), Switzerland (Kaufmann).
