It is unnecessary to carry the synonymy further, as both the 

 name and the description of the genus by its author have been 

 generally accepted, and the numerous references will be found 

 prefixed to the account of the species given, by Miers in 1881. 

 Guerin's dates are often perplexing, but his figure of Eurypodius 

 latreillii in the 'Iconographie,' pi. 11. fig. 1, is referred to by Milne- 

 Edwards in 1834. In the 'Voy. de la Coquille,' his text has a title- 

 page dated 1830, immediately followed by an ' Avant-propos ' 

 dated 1838, and signed Guerin-Meneville, after which comes the 

 description of the Crustacea by Guerin, which was therefore 

 printed and perhaps issued earlier than the preface, aud before he 

 had taken the addition to his name. The excellent figures in the 

 Atlas to the Voyage, pi. 2. figs. 1-11, may have appeared in 1828 ; 

 the date 1826 on the titlepage of the complete volume not testi- 

 fying to anything except perhaps that the titlepage itself was 

 printed in that year. 



The name of the genus expressly alludes to the dilatation of the 

 penultimate joint towards its distal extremity in the four pairs of 

 walking-legs. The species Eurypodius longirostris Miers, 1886, 

 differs from other forms in having the penultimate joint of the 

 trunk-legs very little dilated, as also in having the rostrum bent 

 upward with its two horns apically divergent, somewhat recalling 

 Dana's genus Oregonia.
