The original generic diagnosis of H. Milne Edwards in 1830 is quoted above (p. 

 135). The characteristics: »premier segment du thorax rudimentaire», et »aucune patte 

 n'est prehensile, mais celles de la seconde paire presentent une espece de petite main 

 formee par l'antepenultieme article^ are purely specific, and referable to the species Lestri- 

 gonus Fabrei which then had not any other dascription. His specific description of 1840 runs: 



»Les antennes superieures, plus longues que le corps, ont un pedoncule gros et coude; le 

 premier article est graud et cylindrique; le second est tres-court; le troisieme, presque aussi 

 longue que le premier, s'amincit beaucoup vers le bout, et porte sur le bord inferieur vine rangee 

 de grands poils; enfin le cinquieme et le sixieme sont tres-petits; la tige terminale est extreme- 

 ment longue, filiforme, ayant presque la meme grosseur dans toute son etendue, et divisee en 

 un grand nombre de petits articles. Les antennes inferieures ont a peu pres la meme longeur, 

 es leur pedoncule est gros, conique et compose de trois articles; enfin la tige terminale est grele 

 et filiforme comme celle des antennes superieures. Les palpes mandibulaires sont petits. Les 

 pates de la premiere paire sont tres-courtes et cylindriques; celles de la seconde paire, ont la 

 meme forme que chez les Hyperies; enfin le premier article des six dernieres est large et lamel- 

 leux. Ce petit crustace, long d'environ cinq lignes, a 6te trouve dans la mer des Indes par 

 M. FabrE». 



In 1852 Dana described under the name Lestrigonus Fabrei an animal which how- 

 ever is not identical with H. Milne Edwards' species, as I have already said above (p. 

 140), and which will be described below as the type for Hyperia, Dance. When Spence 

 Bate in 1862 recorded Lestrigonus Fabrei he reproduced Dana's drawing and applied to it 

 the description given by H. Milne Edwards, and thus he failed to recognise the true species. 



Among all the forms of Hyperia which I have examined that described here below 

 most closely agrees with Lestrigonus Fabrei, H. Milne Edwards, and therefore I have 

 adopted the specific name Fabrei for it, the more so as there are specimens of this species 

 in the collection of the »Musee du Jardin des Plantes» from Indian Sea, but without spe- 

 cific name. Of the other specimens of Hyperia in the same collection none agrees with 

 the original description of Lestrigonus Fabrei. 



In general appearance and some characteristics Hyperia Fabrei closely agrees with 

 H. luzoni, but is easily distinguished by the small but distinct carpal process, and the 

 serrated, not notched hind margin of the metacarpus, of the first pair of pereeopoda, and 

 by the telson being much shorter than half the peduncle of the last pair of uropoda. 



The male. 



The body is slender; the head and person together are much shorter than the 

 pleon and urus together. 



The head is very large, and nearly as long as the five first pergonal segments 

 together; it is more than a third part deeper than long, the depth fully equalling the
