METAGRAPSUS PUNCTATUS. 31 



cheir , the sides of the abdomen being less distinctly con- 

 cave, as has been said already by Mr. Miers.

This species is identical with Metagrapsus curvatus M. 

 Edw., (Milne Edwards, Arch, du mus. t. VII, pag. 160, 

 pi. X, fig. 3). 



Mr. Herklots did not describe the structure of the ex- 

 ternal maxillipeds, nor the form of the female abdo- 

 men. This may have been the reason , why Milne 

 Edwards could not determine the position of this spe- 

 cies in his system ; — the type , described by Mr. Her- 

 klots, agrees however entirely with the description of 

 Metagrapsus curvatus M. Edw. According to Mr. Milne 

 Edwards , this species inhabits the Senegal , our specimens 

 being collected at Boutry and at Saccondi.

 308, pi. XVII, fig. 2. 



Our collection contains one almost adult male specimen 

 from Padang; breadth of the carapace 26^/3 mm., length 

 20-^/2. This specimen agrees almost entirely with the des- 

 cription of the New-Caledouiau type , but the meropodites 

 of the ambulatory legs seem to be a little less slender and 

 comparatively broader than those which are figured in the 

 » Archives".
