Ill uiHin" (jf its cliaracteTistics Vibilia lungipes vescmblcs I', rohiivt/i, but it is easily 

 distiiiguished by the loiig sleiider pereinpoda of the iifth and sixtli ptiii-s. From Vibilia 

 Edirardvi, probably its iieavest relati\e, it is distiiiguished by the form of the flagellum 

 of tlie lirst ].)air of anteinuv, and bv tlie short uropoda. 



The /waci is deeper than hmg, roiinded below. 



The ei/ea are coraparativel\- large: tlie)' oeeupy inore thaii two thirds of the depth 

 of the head. 



The JJrf--f /iiiii- II/' iiii.friuKjj are tlearl^• as long as tlie head and the lirst pereional 

 segment, the pediinele is sliorter than lialf the lirst joiiit of the liagelliini. 



The i'piinerals are not very large, even. 



The ovitectrices are very large, ovate, those of the foiirth pair the largest. 



The Jirst pair af pereiopoda (Pl. VIII, tig. 27); the fem ur is cousiderablv shorter than 

 the following joints together. The hinder margin of the metacarpus is .straight, strongly 

 serrated. The dactylus is longer than half the metaearpiis, .serrated. 



The xi^cond pa.ir (Pl. \ III, lig. 2s). The tibial process is about as long as half the 

 earpus, fringed with bristles. Tiie earpal process is almost as long as the hinder margin 

 of the metacari^us. The dactvlus is a little longer tiian half tlie metacarpus, serrated. 



The fliird and foHrf/i pairs (Pl. ^'III, tig. 29) are equal, slender. The tibia is not 

 longer than the earpus. The metacarpus is as long as the car])us. The dact^'lus is 

 almost straigiit, shorter than half tlic metacarinis. 



The /r/f/i and si.ii/i pairs (Pl. \'III, tig. oO) are \ ery elongated. The feniur is eloii- 

 gate-ovate. The tibia is much longer tlian the earpus. The metacarpus is much longer 

 than the tibia, but shorter than tlie tibia and earpus together. The dactylus is shorter 

 than a third of the metacarpus. 



The seuentli pair are scarceh' shorter than the fourtli (21:22j. The dactvlus is as 

 long as half the metacarpus. 



The pleon is as long as the last lour pereional segments. 



The lirst .segment of the uras is longer than the two follo\\ing together, the second 

 segment is half as long as the third. The hinder corners of the third segment are feebly 

 rounded, not produeed. 



The uropoda (Pl. \ 111. lig. ol); tlic peduncle of the lirst pair is very broad, .serrated 

 at the outer margin, the rami are lanceolate, acute, serrated. The peduncle of the second 

 pair is narrower.
