of France. The relations to the Natal province are similar to those 

 with Japan, as before observed (p. 1574). Goniograpsus plicatu*, a 

 Hawaiian species, according to Krauss, is also South African. 



Little is known respecting the species of the Raratongan, or Ker- 

 madec provinces. 



The Wangaroa province (Northern New Zealand) is distinguished 

 by an absence of Cancroid forms, as in Southeastern Australia, and 

 rather a prevalence of Grapsoid species. No Squillidce have yet been 

 observed. Among the species peculiar to the province are the follow- 

 ing : Paramithrax Gaimardii, Eurynolambrus australis, Edw., Portunus 

 integrifrons, P. caniharus, Goniograpsus strigilatus, Hemigrapsus crenu- 

 latus, H. Gaimardii, Halicarcinus varius, H.pubescens, Lomis hirta (pos- 

 sibly from Middle or Southern New Zealand), several Porcellance, 

 Paguristes pilosus, Bernhardus cristatus, B. novi-zealandice, Clibanarim 

 cruentatus, Gebia hirtifrons, Paranephrops planifrons, P. tenuicornis, 

 B. cequimanus, Alope palpalis, Hippotyte spinifrons, Palcemon affinis, 

 with species of the Tetradecapodan genera, Idotcea, Armadillo, Sphe- 

 rillo, Oniscus, Scypliax, D., Lygia, Cymotlioa, Nerocila, ^Ega, Spheroma 

 (several species), Orchestia,, ALlorcliestes, Iphimedia, Melita, CEdicerus, 

 Hyperia. 



The genus Hymenicus, which is near Hymenosoma, and the Pla- 

 gusia tomentosa found also at Table Bay, show a relation to the Capen- 

 sian province (South Africa). Palcemon Quoyanus is also stated by 

 Krauss to be a South African species, found at Port Natal. 



The genera Ozius, Hemigrapsus, and Chasmagnathus, and some of 

 their species, are common to the Bass province (Australia) and North 

 New Zealand, showing a relation between the two. Yet the diffe- 

 rence in species is still so great, that they are properly distinct pro- 

 vinces. New Zealand is over twelve hundred miles from New Hol- 

 land, and its Crustacea are hardly as much like those of New Holland 

 as those of Valparaiso. The following genera characterize both Chili 

 and North New Zealand: Cancer, Ozius, Cydograpsus, Paguristes, 

 and Betceus ; and the Cancer Edwardsii and Plagusia tomentosa 

 appear to be common to the two provinces, while the genus Cancer is 

 not elsewhere known out of America and Northern Europe. Palcemon 

 affinis of the Bay of Islands, as Edwards observes, is hardly distin- 

 guishable from P. squilla of the coasts of France and Britain. The 

 species of Portunus in these southern seas are representatives of the 

 most characteristic of European genera, and they belong rather to the
