Voici in extenso la description donnée par l'auteur : 

 (( Carapace valves oval, terminating posteriorly in a rather 

 long sliarp spine directed a liltle backwards, and furnished 

 on both sides with spines. The surface of the shell is reti- 

 culated and hirsute, being roughened ail over with short 

 spines. The margin of the carapace are beset with short 

 spines also, the dorsal margin from the extremity to the base 

 of the head, the ventral margin for nearly half its length. 

 The head is very obtuse and rounded, terminating anteriorly 

 in a short sharp beak. The rami or inferior antennae are of 

 considérable size, and the setae or filaments are finely plu- 

 mose. The sixth segment of body of the animal lias fîve or 

 six projections from it, two or three of which are small and 

 rough with very minute spines. The fîrst is the longest, being 

 prolonged and curved upwards; the second is large and 

 ^vell-marked ; and between the last and the hooks in which 

 this segment terminâtes, the edge is beset with numerous 

 small spines, the inferior six or seven being much the lar- 

 gest. I bave named this DapJmia after my late friend 

 M. George Newport, to whom I am indebted for the spéci- 

 mens send to me sève rai years ago. Hab. India. »
