LEANDF.R CELEBENSIS. lÜ 



in its whole length beyond the end of the auteunal 

 scales, being 7 mm. long; the palm G^'g mm, the fingers 

 3^/2 mm. long. In other specimens the chelae of the 

 second pair only extend beyond the anteunal scales. The 

 inner margin of the short terminal filament of the internal 

 antennae is not serrate, and the branchiostegal spine is 

 strong and quite situated at the margin of the carapace 

 This species seems to be proper to the China sea.

Two fine specimens were collected near the town of Amoy 

 (China).

Branchiostegal spine rather smaller than antennal spine. 

 Short filament of the internal antennae reaching to the 

 end of the rostrum , not serrate , its fourth basal part only 

 united with the other filament. Legs of the first pair not 

 reaching to the end of the antennal scale , those of the 

 second pair reaching with half the palm beyond that scale ; 

 wrist of the second pair rather shorter than the arm and 

 shorter than the hand ; palm a trifle shorter than car- 

 pus, a little tumid, fingers straight as long as the palm. 

 The other legs elongate and a little extending beyond the 

 antennal scale. Length of our specimens (rostrum inclu- 

 ded) 60 mm; length of rostrum 18 mm. This species is 

 closely allied to L. serratus Pennant , but is distinguished 

 by the under margin of the rostrum not being emarginate 

 at its base.
