40S DR MURRAY ON THE DEEP AND SHALLOW-WATER MARINE FAUNA 



G species (or 17 per cent.) arc known from regions north of the tropic of Cancer, but not 



from the intervening tropical zone (see List IIIc.) ; and 



2 species (or G per cent.) are known both from regions within and north of the tropics 



(see ListllL-/.). 



We may now consider in detail the distribution of these 36 species, according 

 to the groups given above, indicating briefly the geographical and bathymetrical 

 distribution of each species outside the region represented by these three Stations ; five 

 of the species (viz., Axinella erecta, Aulocalyx irregularis, Solenosmilia variabilis, 

 Ophiolcbes scortens, and Echinus magellanicus) occur in the previous lists (Lists I. and 

 IT.) and the distributional notes need not be repeated here. 



LIST Ilia. 



In the first place we give a list of the 21 species which are known to occur 

 outside the region under consideration only in somewhat similar latitudes, i.e., in 

 regions south of the tropic of Capricorn. From the distributional notes it will be observed 

 that 2 of the species are known from deep water over 1000 fathoms (the distribution of 

 which has already been discussed in detail) ; other 5 species are unknown in depths less 

 than 150 fathoms ; the remaining 14 species extend into shallow water under 150 

 fathoms.
