THE LAMPROPIDJE 309 



the female carry rudimentary exopods in the shape of 

 two-jointed setiferous appendages ; the male has no pleo- 

 pods. Lamprops jasciata, Sars, is found in Great Britain 

 as well as Norway. In the female the carapace has three 

 oblique lateral folds. The telson terminates in five spines. 

 Lamprops fuscata, Sars, has the carapace smooth in both 

 sexes. Lamprops quaAriplicata, S.I. Smith, from the north- 

 east coast of America, has four lateral folds on the carapace. 



Hemilamprops, Sars, 1882, has the flagellum of the 

 second antennae in the male filiform and as long as the 

 body ; the third and fourth perseopods in the female with 

 rudimentary exopods : and three pairs of pleopods in the 

 male. Hemilamprops rosea (Norman) is British and Nor- 

 wegian. It has the telson ending in seven or eight spines. 

 Hemilamprops cristata, Sars, from the same localities, has 

 the telson ending in three spines, in which it agrees with 

 the Norwegian Hemilamprops uniplicata, Sars. The re- 

 maining species, Hemilamprops assimilis, Sars, has the eye 

 rudimentary, and the telson ending in six spines. 



Paralamprops, Sars, 1887, has no eye. The first maxillae 

 are without ' palp,' this defect being unique in the sub- 

 order. The third and fourth perasopods in the female have 

 rudimentary two-jointed exopods, and the male has three 

 pairs of pleopods. The single species, Paralamprops ser- 

 rato-costata, Sars, was obtained by the Challenger at Ker- 

 guelen Island. 



Platyaspis, Sars, 1870, has no eye. Only the first pe- 

 rteopods in the female have swimming-branches, instead of 

 the first two pairs as in the preceding genera of this 

 family. The male has three pairs of pleopods. The single 

 species is Platyaspis typica, Sars. 



Ghalarostylis, Norman, 1879, has the flagellum of the 

 second antennae in the male reaching to the end of the 

 trunk. There are three pairs of pleopods in the male. 

 The uropods are remarkably long and slender. The telson 

 is short, ending in three spines. The female is unknown. 

 Chalarostylis elegans, Norman, taken by the Porcupine 

 off Rockall, in 109 fathoms, is the only species. It may 

 or may not have an eye, but none has yet been perceived.
