GEOGRAPHICAL DISTRIBUTION OF CRUSTACEA. 1569 



eornis, and Pasipfwea Savignii, appear to belong especially to this 

 province, besides some species of Bernhardus and Crangon. Lithodes 

 rnaia also occurs here. 



III. SOUTH TEMPERATE SUBKINGDOM. 



The provinces of the South Temperate zone, along the west coast 

 of Africa, are, the Angola (warm temperate, three hundred and sixty 

 miles long), Benguela (temperate, nine hundred miles long), and 

 Capen&ian (subtemperate, four hundred and fifty miles long). Nothing 

 is known of the Crustacea of the coasts, excepting in the last men- 

 tioned province, upon which we have already remarked. Hymeno- 

 soma orbiculare is one of the Table Bay species ; and it belongs to a 

 group that is represented only about the southern extremity of South 

 America and in New Zealand. Palinurus Lalandii, another species, is 

 one of the largest of known Macrourans. 



South of the subtemperate region, in the cold temperate, stands in 

 the Atlantic, the island of Tristan D'Acunha, which may be another 

 province, the Tristensian. As mentioned by Krauss, the Spheroma 

 tristense, Edw., is common to this island and Table Bay. 



III. ORIENTAL KINGDOM. 



Turning Cape Agulhas, we soon come into a different Zoological 

 world. The coast immediately east to longitude 30°, belongs still to 

 the Temperate zone, and must constitute a distinct province, which 

 we call the Algoa province (from Algoa Bay), the length of which, 

 measured from Cape Agulhas, is full five hundred and fifty miles. 



Passing beyond this, we reach the Natal province, and here we 

 recognise at once the seas of India and the Pacific Ocean. Krauss 

 mentions eighty-one Natal species of Podophthalmia, not thirty of 

 which are peculiar to this region. Twenty are found in the Indian 

 Ocean, eighteen in the Red Sea, thirteen in Japan, eight in Australia, 

 five in the Isle of France, besides three European species, and three 

 American. We 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 (Calcinus, D.) elegans, Galene
