LIST III h. 



In the second place we give a list of the 7 species which extend into the tropics, 

 but are not known to occur to the north of the northern tropic. From the 

 distributional notes it will be observed that 2 of the species are known from deep 

 water over 1000 fathoms (the distribution of one of which has already been noted) ; 

 other 4 spscies extend into shallow water under 150 fathoms. Two of the species are 

 unknown in depths less than 150 fathoms. 



Solenosmilia variabilis (for distribution, see List II.).

LIST IIIc. 



In the third place we give a list of the 6 species which are known to occur 

 north of the northern tropic, but which have not hitherto been recorded from the 

 intervening tropical zone. From the distributional notes it will be observed that 4 of 

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

 which has already been discussed) ; 2 of the species extend into shallow water under 

 150 fathoms, being at the same time represented in deep water over 1000 fathoms, viz., 

 Axinella erecta and Puncturella noachina, the remaining 3 species being unknown in 

 depths less than 150 fathoms. 



Axinella erecta (for distribution, see List I.). 

 Aulocahjx irregularis (for distribution, see List I.). 



Ohonelasma lamella — Near Kermadec Islands, 630 fathoms; North Atlantic near Bermuda, 1075 fathoms. 

 Flabellum apertum — North Atlantic, off coast of Portugal, 900 fathoms. 

 Ophiacantha rosea — Magellan Strait, 175 fathoms ; near Japan, 420 to 775 fathoms. 



Puncturella noachina — Marion Island, 69 and 140 fathoms; Kerguelen, 60 fathoms; Magellan Strait, 9 to 15 

 fathoms ; Arctic, North Atlantic and North Pacific, 5 to 1095 fathoms. 



LIST III d. 



In the fourth place the following 2 species occur both in the tropical and 

 northern extra-tropical regions ; they are unknown in depths over 1000 fathoms, and 

 extend into shallow water under 150 fathoms.
