30 SESARMA AUBRYI. 



in breadth ; tufts of hair large and numerous , especially on 

 the anterior part of the carapace ; upper margin of the mo- 

 bile fino-er with three black spines, the hindermost being 

 rudimentary. 



The specimen from Nossy-Faly, a female , 24 mm. broad , 

 has the carapace nearly without tufts of hair. 



The terminal joint of the abdomen of young female spe- 

 cimens is comparatively less profoundly pushed into the pre- 

 ceding than that of adult specimens.

There is a very line adult male specimen in the collec- 

 tion , found at Amboina. To what has been mentioned by 

 Messrs. Milne Edwards and Miers , about this species we 

 wish to add that — 



Though the carapace is generally smooth , the swollen 

 epibranchial regions are a little rugose and obhquely wrin- 

 kled ; the front is nearly vertical and granulated , compara- 

 tively higher than that of Ses. Holomet. haematocheir de 

 Haan , with an entire arched anterior margin ; in the Ja- 

 panese species this margin is straight and a little reflexed 

 upwards. The lateral margins of the carapace end about 

 above the third pair of legs in Ses. a?/ir!/i, but in the other 

 species above the fourth pair. Anterior margin of the 

 arm of the anterior legs entire; in Ses. haematocheir it 

 is delicately ,toothed. In the latter species the upper 

 margin of the meropodites of the ambulatory legs is 

 provided with a small sharp spine near its distal end, 

 which is not found in Ses. auhryi. Finally the penul- 

 timate joint of the male abdomen of Ses. auhryi is com- 

 paratively broader and less high than that of Ses. haemato-
