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

 cheHpeds the finger and thumb have three or four teeth at tli^ 

 distal part of each inner margin, not large, but 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. 



Length of carapace in the male specimen, 11.25 """• by a 

 breadth of 10 mm. 



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 

 sand.

 The French authors above cited divide the Brachyura into 

 Dromiacae or iJrachyures primitifs and Brachyura genuina. 

 The Dromiacea or Brachyura anomala comprise three legions or 

 three families, Dromiidae, Homolidse, and Dynomenidae, in 

 ac( t)rdance with Ortmann's arrang-ement 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 his Dromiacea the four genera 

 Dynomene, Homola, Dromia, Latreillia, remarking that " the 

 Dromiacea, with exclusion of Lithodidse, 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 the Brachyura. Alcock, whose classification 

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

 plained, divides the Brachyura anomala into two tribes, the 

 Dromiidea and Homolidea, the former including the three
