carapace (Fig. iSa) this lobe looks like a short acute spine, nearly as in Dana's figure 6a. 

 According to my description of 1 9 1 1 these prominences of the orbital hoods did also occur in 

 an adult male from the west coast of Flores and in other specimens, but sometimes were less 

 conspicuous and this is also the case in the preceding specimens from Stat. 273 and from the 

 Bay of Batavia. The acute tooth on the merus of the y^ (Fig. 18^) and 4"^ legs is in this female 

 much smaller than in the preceding specimens, looking exactly as in Dana's figure 6/. This 

 specimen should therefore perhaps be referred with more right to the true A. euchirus Dana, 

 but it appears still uncertain, because, like in the preceding specimens, the merus of the 1*' pair 

 of peraeopods is armed with an acute tooth at the infero-internal margin, while according to 

 Dana ("brachio apicem non spinigero") the merus should be unarmed. The large chela, on 

 the right side, agrees with the preceding specimens, it is 17 mm. long, the palm 12 mm.; the 

 smaller chela is 12,5 mm. long, fingers as long as the palm, that is 3 mm. high. (In D.\na's 

 figure 6d the palm appears much higher, but this figure no doubt represents the small chela 

 of the male). 



The identification of these specimens with Dana's species appears therefore still doubtful.
