350 Geographical Distribution of Crustacea. 
The genus Xantho, in X. rivulosus and X. floridus oid 
reaches its extreme cold limit in the Celtic Province. Nephro 
norvegicus, although more properly pertaining to the next one 
ince north, occurs also within the limits of this; and it has even 
been taken in the Mediterranean. Stenorhynchus phalangium 
and Portunus pusillus, reach south into the Mediterranean and 
north to the Frigid zone; Portunus holsatus, Galathea strigosa, 
and Forceliane platycheles, south to the Canaries and north into 
the su id. 
Tuiening Cape Agulhas, we soon come into a zoological world 
- widely different abe that of the Atlantic coasts. The coast im- 
mediately east to longitude 30°, belongs still to the male 
zone, and constitutes a distinct province, which we call the Algoa 
Province (from Algoa Bay), the length of which, pee from 
Cape Agulhas, is full five hundred and fifty mile 
Passing beyond this, we reach the Natal sale 1 and here 
We recognise at once the seas of India and the Pacific Ocean. 
Krauss mentions eighty-one Natal species of a aga not 
thirty of which are peculiar to this region. Twenty ar e foun 
in the Indian Ocean, eighteen in the Red Sea, thirteen in ig ee 
eight in Australia, five} in the Isle of France, besides three Euro- 
pean species, and three American. e observe further that, 
twenty-two of the species of Podophthalmia occur in the Pacific 
Islands, among which are four species supposed by Krauss to be 
peculiar to Natal, viz., Pagurus (Clibanarius, D.) virescens, Kr., 
Pagurus ( Calcinns D. ) pinton Galene natalensis, Kr., Platy- 
onychus (Kraussi ‘ay rugulosus, Kr., all of which occur at 
the ee Islands.* 
he E'uropean species, one is the cosmopolite Gonodactylus 
nee Latr. ‘The others are Alpheus Edwardsii, and Gam- 
marus pulex, Fabr. Megalopa mutica and Hi olyte ensiferus, 
also reported from South Africa, do not occur at Port Natal. The 
American are the cosmopolites Goniograpsus pictus, and Gono- 
dactylus chiragrus, together with Eriphia gonagra, Edw. The 
Sesarma reticulata, Say, and Pog tomentosa, Lk., also 
South African, are not from Port Nat 
range of the tropical and subtropical waters. The African sec- 
tion here includes the east coast of Africa, with the adjoining 
islands ; the Indian, the East Indies, southeast and east coast 0! 
: Asia, and Eastern Australia; the Pacific, the Pacifie Ocean.7 
* The Galene hawaiensis, D., is so closely like the G. natalensis, that we believe 
there is not sufficient reason for considering them distin 
mye stands for Isle of France; E.L for East Tatas Haw. for Hawaiian Isl- 
Jap. for Japan; Nat. for Natal; Feej. for Feejees,
