Ivi PROCEEDINGS OF THE 



death by Keferstein and others, which I mentioned in my Ad- 

 dress of 1866, has advanced but slowly. The Amorphozoa, Acti- 

 nozoa, and Malacozoa, forming the first two volumes, were then com- 

 pleted ; and Gerstacker has since been proceeding with the Arthro- 

 poda, commencing with the Crustacea, for the third volume, of which 

 only the general matter and the Cirripedia and Copepoda are as yet 

 published ; and three or four parts of a sixth volume for Birds have 

 been issued by Selenka, treating the anatomical and other general 

 matter in great detail. Another general work of merit, although on 

 a smaller scale, has been proceeding as slowly. Of Cams and 

 Gerstacker's ' Handbuch der Zoologie,' the second volume, contain- 

 ing the Arthropoda, Malacozoa, and lower animals, had been already 

 published in 1861 ; and to this was added, in 1868, the first half of 

 the Vertebrata for the first volume, with a promise that the re- 

 mainder should appear in the autumn, but which has not yet been 

 fulfilled. Among the other recently published systematic zoological 

 handbooks of which I have had memoranda as published in various 

 Continental states, the most important are said to be : — Harting's, 

 published at Tiel in the Netherlands, of which, up to 1870, only 

 three volumes had appeared, containing the Crustacea, Vermes, Ma- 

 lacozoa, and lower animals ; A. E. Holmgren's Swedish ' Handbok i 

 Zoologi,' of which Mammalia were published in 1865 and Birds in 

 1868-71; and Claus's 'Grundziige' and Troschel's 'Handbuch' 

 (7th edition) for University teaching in Germany, 



In a comparative sketch of the more partial Monographs, Faunas, 

 and Floras, I had wished to direct my attention more especially to 

 the means afforded us of comparing the plants and animals of 

 different countries; and with this view one of the questions I 

 addressed to foreign zoologists was, "What works or papers are there 

 in which the animals (of any of the principal classes) of your country 

 are compared with those of other countries ? " The answers to this 

 query have not been generally satisfactory. Where the zoology has 

 been well investigated, we have popular handbooks, elaborate 

 memoirs, and works of high scientific value or splendidly illustrated. 

 But short synoptical faunas, so useful to the general naturalist, and 

 corresponding to the Floras we now possess of so many different 

 countries, are very few ; the statement of the general geographical 

 range of each species, so prominent a feature in many modern Floras, 

 is still less thought of ; and indications of allied or representative 

 races in distant countries are equally rare. We have, indeed, several 

 excellent essays on the geographical distribution of animals (I had 

 occasion to allude to several of them in my Address of 1869) ; but
