they are in general chiefly devoted to discussions, with statements of 

 such facts only as bear upon the author's conclusions, not records of 

 all facts which may be useful to the geographical or general biologist. 

 These must be collected from a great variety of separate works and 

 papers, of which I have received long lists from Denmark, Sweden, 

 Germany, Switzerland, Italy, France, and the United States. As 

 yet 1 have only had time to refer to a few which appeared to bear 

 more immediately on the objects I had in view ; but I hope on some 

 future occasion to return to the subject. In the mean time I must 

 content myself with glancing rapidly over the different countries, 

 taking them in the order adopted in my former Addresses, and 

 endeavouring to show the progress making in supplying our de- 

 ficiencies. Towards these deficiencies I would particularly caU the 

 attention of entomologists and terrestrial malacologists ; for insects and 

 land-sheUs are of all others the animals whose life and local stations 

 are the most closely dependent on vegetation. In the following 

 notes I refrain from entering into any details as to the zoological 

 works or memoirs mentioned, as they are entirely superseded by the 

 analysis given in the annual review inserted in Wiegmann's 'Archiv,' 

 and more especially in our own admirably conducted 'Zoological 

 Record,' which so strongly claims the support of every one interested 

 in the promotion of Zoological Science. 



I. Denmaek. 

 In geographical biology Denmark proper is of no great importance 

 except as a connecting-link, on the one hand, between the Scandina- 

 vian peninsula and Central Europe, and, on the other, as the 

 separating barrier between the Baltic and the Xorth seas. Low and 

 flat, without any great variety in its physical features, it is un- 

 favourable for the production or maintenance of endemic organisms, 

 and forms an inseparable portion of the region of Central Europe. 

 But the Arctic possessions included in the kingdom, Greenland, 

 Iceland, and the Faroe Islands, are of great interest ; and Denmark 

 itself is remarkable for the number of eminent naturalists, zoologists 

 as well as botanists, produced by so small a state. Its reputation 

 in this respect, established by the great names mentioned in my 

 review of Transactions in my Address of 1865, is berng weU kept up 

 by Bergh, Krabbe, Liitken, Morch, Reinhardt, Schiodte, Steenstrup, 

 and others in zoology ; whilst Lange, (Ersted, and Warming are 

 among the few who now devote themselves more or less to syste • 

 matic botany. Their general zoological collection, when I last visited 

 it, many years since, was not extensive, although rich in northern
