"Wright — On a New Genus of the Family Pandarina. 585 



The four pairs of abdominal feet are two-branched, and in the first 

 three pairs each of these branches (figures 10, 11, and 12) are two- 

 jointed, each of the joints being- clothed with large bristles lined with 

 hairs. The first pair possesses the smaller mimber of bristles, and tliere 

 are no bristles on the first joints; the second and third pair have, on 

 the inner edge of both the first joints, a well marked, long, ciliated 

 bristle. The fourth pair (figure 13) is not fully furnished with 

 bristles, and these are not clothed with cilite ; and they are also not 

 two-jointed, and in this, as in the number of bristles, differ very mate- 

 lially from the first three pairs. 



The average length of the specimens examined is six millim. All 

 the specimens met with were females. 



In conformity with the practice of Heller, Steenstrup, Lutken, 

 and others, I describe the swimming feet as abdominal — (abdominal 

 fusspaare : bagkropsfodderne) ; but it would have seemed to me more 

 natural to have described them and the somites from which they 

 spring as thoracic. Heller gives "' a conspectus of the Family Pandarina, 

 including all the genera known to him. This new genus it appears to 

 me might come in after Demoleus. the remi of the third pair not being 

 ■* biarticulati', and not being ' setis plumosis ornati.'
