PUOCEEDINGS OF THE MALACOLOGICAL SOCIETT. 251 



Professor Howes was essentially a teacher and lecturer. His 

 mastery of detail was surprising, and a fault, if it could be regarded 

 as such, was the enormous mass of facts which crowded his addresses, 

 showing the vast amount of reading and study which he had devoted 

 to their preparation. Nothing seemed too minute in detail to him 

 to be passed over, and this completeness was a marked character 

 of his researches. Perhaps the bulk of his writings may not be 

 great, but many of his memoirs were important contributions to 

 science, adding much to his repute as an accomplished and original 

 investigator. Apart from his loss to the scientitic world, his death 

 must be deplored very deeply by all those who had the privilege 

 of knowing him personally. He was exceptionally charming and 

 kindly in disposition, and ever ready to assist anyone who was desirous 

 of consulting him for advice and assistance.

Professor Dr. Carl Eduard von Martens, a member of this Society 

 since the year 1893, died last year, on August 14th, aged 73. He 

 was born at Stuttgart in 1831, and studied both medicine and natural 

 history. He was appointed assistant in the Zoological Museum of 

 the Berlin University in 1855, with which institution he was con- 

 nected for fifty years. In 1859 he became attached to the Museum 

 fiir Naturkunde in Berlin, of which he eventually became second 

 Director, and in recent years he was honoured with the rank of 

 Privy Councillor. 



In 1860 he accompanied the Prussian expedition to Eastern Asia 

 in the " Thetis," visiting Japan, China, Siam, Java, and Celebes. He 

 also explored the Sunda Islands. On his return to Europe he worked 

 out the collections obtained during the expedition, and published 

 the results in two volumes, constituting the Zoologischer Theil of 

 the "Preussische Expedition nach Ost-Asien." Vol. ii, consisting of 

 447 pages and 22 plates, contained a very full account of the land 

 molluscs.

 on the land and fresh-water MoUusca in the " Biologia Centrali- 

 Americana," occupying 706 pages and illustrated with 44 plates ;
