The original generic diagnose of H. Milne Edwards run.s as follows: 



»Tete grosse et renflée; antenncs stylitornies et rudinientaires; thorax conique, trés- 

 étroit postérieurement et aj^ant le pi"eniier segment trés-coui-t; pattes des deux premiéres 

 paires portant ime main imparfaitenient didactyle, dont le doigt inobile est foriné par les 

 deux derniers artides; abdomen corame dans le geni'e Hypérie.» 



Daira was mentioned låter by H. Milne Edwards and H. Lucas, as -will be seen 

 froiu the list of synonyms above, and some few characteristics were added, but unfortu- 

 nately no drawing -was given. In 1852 Dana quotes Daira and proposes for it the new 

 name Dairinia or Dairilia, Daira being preoccupied by Leach for a genus of crabs. 

 But as he totally misunderstood the " diagnosis of Milne Edwards and applied the new 

 name on animals Ijelonging to a widely distant family of Hyperids, the Lycceidte, the 

 name Dairinia must be rejected, and the original one, Avith a slight correction, restituted. 



From Paraphronima this genus is distinguished by the cheliform second pair of 

 pereeopoda. Most of the other characteristics quoted by Milne Edvards as generic have 

 probably only specific value, and are mentioned below in the description of the species. 



1. EUDÅIBA GABERTII, H. MILNE EDWARDS, 1830. 



Diagll. Caput magnum, tumiduni. Antenua; priini paris feminaj, ciirta? subulatas. Segmeutum pri- 

 mum peran brevissimuni. Processus carpi pedum penei secimdi paris nietacarpo paullo 

 brevior. Pedes tertii ac quarti parium pedibus quinti ac sexti parium multo longiores. 



The liead is large, tumid. The first pair of antennje in the female are short, subidate. The 

 first perceonal segment is verv short. The carpal process of the second pair of perwopoda 

 is a little shorter thau the metacarpus. The third and fourth pairs are much longer than 

 the fifth and sixth.
