of the deep sea. In the introduction to this fine treatise his experienced 
remarks on phosphorescence and on the nature and distribution of deep-sea 
fishes are of great value and interest. This volume is illustrated by no less 
than 72 plates, many of them double, and admirably drawn by Mintern 
Bros., the successors of G. H. Ford. 
His report on the shore fishes collected by the Challenger was 
published before the preceding treatise, and comprised an account of 1400 
species, of which 94 were new to science. Only a skilled ichthyologist 
could thus have worked out the collection with such rapidity, for it was 
issued in 1886, when Sir Wyville Thomson was still at the head of affairs. 
Rare forms from the tropical Atlantic, Bermuda, the temperate zone of 
the South Atlantic, of the Antarctic Ocean, the temperate zone of the 
South Pacific, of Japan, and the neighbouring regions were accurately 
described and figured. This and the foregoing volume would alone have 
made a reputation. Moreover, it gave Dr Gunther an opportunity of 
widening our views with regard to the mutual relations of the fishes of 
deep and shallow water, and of demonstrating the wide range of many 
forms both in depth and locality. 
One of his greatest services to the science of zoology as a whole, and one in 
which his work has directly proved a boon to all his fellow- workers, is the 
Record of Zoological Literature , which he founded in 1867 and edited for 
several years. Investigators have thus a ready means of making themselves 
acquainted with contemporary work in every country. This step alone 
would have earned the thanks of every zoologist, and its continuance to-day 
by the Zoological Society shows its permanent importance. The work must 
have given Dr Gunther much thoughtful labour and care, and could only 
have been undertaken by one in a central position, and with the co-operation 
of a wide circle of zoological friends at home and abroad. 
His Introduction to the Study of Fishes (1880) is another treatise 
which has had a widespread popularity — from the masterly way in which 
the author handled a subject to which he had devoted the best part of 
his life. No student of the group can find a more comprehensive yet 
concise treatise in any language, and none having an equal amount of 
reliable information. His chapters on the distribution of fishes — geological 
and geographical — are especially full of experienced remarks. 
Though Dr Gunther in his early days made a few of his own drawings, 
he soon became so occupied that it was necessary to employ others, and 
he was fortunate in securing for many years the services of G. H. Ford — 
who was facile princeps in lithography during his day, and who in the 
delineation of the lower vertebrata has never been surpassed — and he
