shorter than the third, the cxopod moderately expanded. In the 

 chelipeds the finger and thimib have three or four teeth at the 

 distal part of each inner margin, not large. l)ut more decidedly 

 developed than any on the earlier part of the margins. In the 

 male the third, fourth, and fifth segments of the pleon are 

 coalesced, in the female, these, together with the sixth.

Locality: — Mossel Bay. 



Bell's specimen, half an inch in length of carapace, was 

 dredged in Simon's Bay, between four and seven fathoms, on

 The French authors above cited divide the Brachyura into 

 Dromiacae or Urachyures primitifs and Brachyura genuina. 

 The Dromiacca or Brachyura anoniala comprise three legions or 

 three families, Dromiidae, Homolida?, and Dynomenidae, in 

 accordance with Ortmann's arrangement of the Dromiidea in 

 1892. The authors who have taken the lead in re-establishing this 

 classification have fully recognized the claim of de Haan to its 

 origination. He included in liis Dromiacca the four genera 

 Dynomene, Homola, Drotnia, LatreiUia, remarking that " the 

 Dromiacea, wdth exclusion of Lithodidas. seem to be far removed 

 from the Anomoura, and especially from the Raninoidea and 

 Paguridea." .So circumscribed, he concludes that they ought not 

 to be separated from tlie lirachyura. Alcock, whose classification 

 is at once the most recent and the most fully and clearly ex- 

 plained, divides the Brachyura anoniala into two tribes, the 

 Dromiidea and Homolidea. the former includin<r the three
