dilatato scutiformi. Epimera satis lata : quarti articuli majora, inferne postice distincte 



producta, ilia articuli quinti circum-dantia." 

 " Callisoina pundaia, 0. G. Costa," is described and figiu'ed. The short definition is : — 



" C. corpore dimidio fere longitudinis alto, epimeris artiouU quarti thoracis postice ad 



illorum quinti angulum infero-posteriorem usque productis ; carneus, macuUs punctiformihus 



crehris ordinatis rubro-sanguiueis pictus ; oculis nigris, an tennis pedibusque pallidis. — Long. 



lin. 3J ; alt., max. lin. 1 4/10." 

 " Gallisoma Hopei " is also described and figured, being distinguished from Callisoma pundatum 



chiefly by the absence of the dendi'itic spots, and by the different development and shape of 



the side-plates. The genus Lysianassa, Milne-Edwards, and the type species Li/sianassa 



eostee, Milne-Edwards, are described. 

 The genus Talitnis, Latreille, is described, and Talitrus platycheles, Guerin, is described and 



figured. The genus Orcliestia, Leach, is described, and the species Orehestia desltayesii, 



Audouin, is described and figured.

 Hope. Napoli, 1851. 48 pages. 1 Plate. 



Though A. Costa's name does not appear on the title page the work appears to be at least as 



much due to him as to the Rev. F. W. Hope. 

 The Catalogue differs so strikingly from most catalogues of Amphipoda that I give the 



Amphipodan portion in full.
