Second maxilla with 3 simple spines on outer lobe and 2 plumose 

 setae on inner. 



Maxilliped without recurved spines on the terminal, all joints 

 as well as the large epipod fringed with plumose setae, posteriorly 

 directed laminar expansion of the 1st joint very large, posterior 

 margin rounded. The loss of the terminal recurved spines and 

 the enlargement of the epipod and basal joint are evidently features 

 of the ovigerous female. The first is correlated with the fact that 

 ovigerous females are never captured on the host like the males 

 and immature specimens, but are found free-living on the sea- 

 bottom where they probably take no food. The epipod and the 

 basal plate serve to produce a current of water through the 

 marsupial pouch, the same structure being found in other families, 

 e.g., Astacillidae (see Hansen, Cirolanidae, 1890, p. 287). 



First to third peraeopods with 6 spines on inner margin of 4th 

 joint instead of the 7 found in Ac. truncata. 



Second pleopod with 10 hooked spines and numerous plumose 

 setae on inner margin of peduncle. 



Uropods as in Ac. truncata, but with stout spines as well as 

 plumose setae ; outer margin of outer ramus with 2 spines and 

 indications of 2 more, posterior margin of inner ramus with 6 spines 

 on the right, 2 on the left, the rest having been broken off. 



Length : 53 mm. ; breadth : 24 mm.
