40 CARCINOLOGICAL STUDIES. 



some mostly young individuals from the Banda Sea, and 

 twelve young specimens from Amboina. 



This species is closely allied to the preceding and to 

 Gelas. Latreillii M. E., of which I have a Paris type be- 

 fore me. The cephalothorax is strongly convex in the an- 

 tero-posterior direction and comparatively a little longer 

 in proportion to the distance between the 

 external orbital angles than that of Gelas. annu- 

 lipes. The orbits in the male are rather much oblique, the 

 external orbital angles acute and directed obliquely 

 outward, whereas they are directed straightly forward 

 in Gelas. lacteus de Haan. The lateral margins are rather 

 oblique and converge rather much backwards , a little 

 more in the male than in the female. I do not observe 

 accessory granules on the wall of the orbits of the fema- 

 les near the lower margin, which exist in the female of 

 Gelas. annulipes. 



The larger hand of the male agrees with the figure of 

 Milne Edwards (PI. IV, fig. I7a). The distal crest on the 

 inner surface near the articulation with the dactylus is 

 represented in the male from Samoa only by two small 

 granules, and the other is also very indistinctly granula- 

 ted; but in the male from the Banda Sea I observe two 

 parallel distal rows of granules near the articulation of 

 the mobile finger. I suppose that the development of these 

 rows of granules is somewhat variable according to the 

 individuals. In both males the lower finger presents a very 

 small tooth close to the extremity; it bears, moreover, 

 some more or less prominent granules, and in the male 

 from the Banda Sea even a small tooth in the middle of 

 the margin. The upper finger is strongly arcuate in the 

 male from Samoa and appears unarmed , but in the male 

 from the Banda Sea a few prominent gianules are obser- 

 ved along the proximal half of the margin. 



The meropodites of the ambulatory legs are a little more 

 enlarged than those of Gelas. annulipes.
