1. Atergatopsis Amoyensis n. sp. 



This species is closely allied to Atergatopsis granulatus 

 Alph. M. Edw. and to Atergatopsis Lucasii Montr. It has 

 the physiognomy of the former , but the lolioh surface of the 

 carapace is uniformly covered with close minute granules , 

 which are somewhat greater on its lateral regions than in the 

 middle ; there are also a few short stiff hairs on the carapace 

 and on the legs. Front bilobed, formed by two rounded 

 lobes which are very granular and separated by a rather 

 deep incision. Interregional grooves very shallow, faintly mark- 

 ed. Latero- anterior margin with three small granular teeth , 

 one on the middle, the second at the posterior edge of the 

 margin , the third between the two other ones. The pleural 

 lobes and the whole inflected portion of the carapace also 

 somewhat granular, as also the two basal somites of 

 the abdomen which is constituted by 5 segments. The 

 chelipedes are nearly equal; the meropodites covered by the 

 carapace; the outer surface of the carpopodites , and the
