KOBELT : OTTO FRANZ VON MOELLENDORFF. 125 



in the campaign against Peking, and by his communications the birds and 

 mammals of the North of China have been more accurately made known. 

 Later he concentrated his attention more and more on the Land Shells, but 

 even in the Philippines he continued to collect all kinds of animals which did 

 not require a troublesome preparation, and willingly and most unselfishly 

 placed his material at the disposal of amateurs. Even his investigations 

 of New Guinea, and later of Indo-China, have proved of great service. 

 His last work, during which death itself took the pen out of his hand, was 

 the working up of the collections made by Russian investigators in the 

 centre of China and Tibet. The examination of travellers' collections 

 of this kind he was very fond of. 



His papers appeared, for the greater part, in the " Jahrbucher" and 

 "Nachrichtsblatt" of the German Malacological Society, as well as in the 

 Jahresiberichten of the Senckenberg Society, some in English periodicals, 

 as the Proceedings of the Zoological and Malacological Societies of London, 

 the Annals of the Calcutta Museum and of the East Asiatic Society, and 

 the Annals of the St. Petersburg Museum. Of the Molluscan Fauna of the 

 Philippines, a supplement to Semper's Fauna, and as a part of Semper's 

 great work, he only accomplished the Agnatha and Naninae; and only the 

 two first parts, containing the lihytididae, of the monograph of the Agnatha 

 for the second edition of Martini and Chemnitz.
