Madeira, St. Helena, Ascension and other 

 volcanic islands constitute such, halting 

 places. We shall find many more such, 

 when the deeper shore regions are explored, 

 the region between market-fishing and the 

 deep-sea dredgings of the Challenger and 

 the Albatross. In some cases, no doubt, 

 these forms are verging on extinction and a 

 former Tide distribution has given place to 

 isolatea colonies. 



The following table shows the contents, 

 so far as genera are concerned, of those 

 equatorial areas in which trustworthy cata- 

 logues of species are accessible. It includes 

 only those fishes, of stationary habit, living 

 in less than 200 fathoms. It goes without 

 saying that considerable latitude must be 

 given to these figures, to allow for errors, 

 omissions, uncertainties and differences of 

 opinion.

* Lepadogaster, 3Iyrus ; Lophotes, thus far recorded 

 from Japan, the Mediterranean and the Cape of Good 

 Hope is bassalian and of unknown range. Beryx, 

 Trachichthys, Hoplostethus, etc., are virtually cosmo- 

 politan as well as semi-bassalian. 



t In this group we must place Cepola, Callionymus, 

 Pagrus, Sparus, Beryx, Zeus, all of which have a very 

 wide range in Indian waters. 



X Cryptocentrus, Asterropteryx. The range of neither 

 of these genera of small shore fishes is yet well known.

t Bairdiella, Aboma. The occurrence of Bairdiella 

 acanthodes in Japan needs verification. 



X Scombrops, Polymixia, Pseudopriacanthus, Anti- 

 gonia, Chaunax. All these genera are semi-bassalian. 



§ Sectator, Chsenomugil, Garmannia.
