The following are the provinces belonging to the three subkingdoms, 

 the torrid, the north temperate, and south temperate : 



I. TORRID SUBKINQDOM. 



1. The GUINEAN Province (torrid), including the coast of Guinea to 

 9 north or Sierra Leone. Length, twelve hundred miles. 



2. The VERDENSIAN Province (north subtorrid), including the coast 

 from 9 north nearly to Cape Verde, and also the Cape Verde Islands. 

 Length on the African coast, three hundred and fifty miles. A 

 species of Actceodes (A. faba) occurs here, the only one of this warm- 

 water genus yet known in the Atlantic. 



3. The BIAFRIAN Province (south subtorrid), including part of the 

 African coast near the equator, about the Bight of Biafra, and reach- 

 ing to 7 or 8 south; and also the islands Ascension and St. Helena. 

 Length on the African coast, nine hundred miles. 



II. NORTH TEMPERATE SUBKINGDOM. 



1. The CANARIAN Province (warm temperate), including the west 

 coast of Africa to the latitude of the Canaries, and embracing these 

 islands. Length on the African coast, one thousand miles. In 

 this province there are several species from more tropical regions, 

 which here reach their northern limit, such as Pilumnus fbrskalii, 

 also from the Ked Sea ; TJtalamita admete, East Indies, Natal, &c. ; 

 Grapsus strigosus, East Indies, &c. ; Goniograpsus messor, East Indies, 

 Red Sea, &c. Oplophorus spinosa (= Palaemon spinosa, BrulU), 

 Leptopodia lanceolata, Cycloes cristata, Squilla oculata, are reported 

 only from the Canaries; though the Cycloes resembles closely a Japan 

 species, if it be not identical with it. Many of the species of the 

 British Channel here reach their southern limit ; for example, Inachus 

 dorhynchus, Maia squinado, Pisa tetraodon, Xantho rivulosus, Portunus 

 corrugatus, Gonoplax angulata, Goniograpsus varius, Atelecyclus cru&nr 

 tatus, Dromia vulgaris, Porcellana platycheles, Galathea strigosa; these 

 are found also in the Mediterranean. There are besides many other 

 Canarian species that are found in the Mediterranean, which do not 

 extend to the north, e. g., Herbstia condyliata, Actcea rufo-punctata, 

 Eriphia spinifrons, Lupa hasiata, Amphitrite hastata, Portunus holsatus,
