C'fi»li;ilon transvei-sely oviite, Superior antonnoe reaching to the 

 Iburth or fifth segincnt of the pcrcion ; first joint of the ix'clunclo 

 short, but longer than the second and third together ; fii"st arti- 

 ciUus of the flagellum twice as long as the peduncle, and tapering 

 to the distal extremity, the other articuli of the flagellum being 

 short— those near the base not longer than broad. Infciior an- 

 tenna} a little shorter than the superior ; the peduncle concealed 

 as far as the extremity of the fourth joint ; fifth joint slightly 

 cui-ved, and reaching to the extremity of the peduncle of the 

 superior antennae : firet articulus of the flagellum as long as the 

 last joint of the peduncle ; the remaining articuli, being very short, 

 resemble those of the superior anteunte. First pair of gnathopoda 

 small, having the carpus and meros but slightly produced in- 

 feriorly, and the antero-inferior margin fringed •with hairs ; pro- 

 podos of the same length as the carpus, nuich narrower, and 

 almost cylindrical ; dactylos very short — too short to antagonize 

 with the produced extremity of the carpus. Second pair of gna- 

 thopoda rather longer than the first, and having the carpus and 

 meros more produced than those of the fii'st ; propodos scarcely 

 longer than the caipus, not half its width, and having the supe- 

 rior and inferior margins fringed with hairs ; dactylos about half 

 the length of the propodos, and capable of reaching the extremity 

 of the produced carpus. Pereiopoda subequal and tolerably robust. 

 Antepenultimate and penultimate j)airs of pleopoda short, sub- 

 equal : ultimate pair longer, the peduncle extending to the ex- 

 tremity of the preceding pair ; rami half the length of the pe- 

 duncle. Telson broadly lanceolate. 



Length i^ths of an inch.

I have taken the description pnd figure from a single specimen in 

 the collection so courteously entrusted to nic ])y Prolessor Milne- 

 Edwards. It is labelled Jhiperia GaudicJuiudii, and not having seen 

 any other specimen in the collection of the Jardin des Plantes, I 

 assume this to be the type from which the author drew up the 

 original description. It closely resembles L. e.xntlans, but may be 

 at once recognized by the distinct arniature on llie ])ropoda of tlio 

 gnathopoda.
