514 A NATURALIST ON THE " CHALLENGER." 



illustrating the development of two species of Sergestes, and 

 three on the development of Amphion. Four are of Pteropods. 

 One of these, labelled by Von Suhm as Chionider Pterojpod, is a 

 most remarkable form, with large eyes borne on long stalks. 

 Yon Suhm was uncertain whether it was to be regarded as the 

 larva of a new form of Cephalopod. It has two arms only, 

 apparently homologous with the tentacular arms of Decapod 

 Cephalopoda. 



Besides these drawings Von Suhm left two closely written 

 volumes of zoological journal in German and one volume in 

 English. It is to be hoped that the German journal will be 

 published in due course. It cannot but contain much most 

 valuable matter. Besides this work Von Suhm constantly kept 

 during the voyage the tabular record of the results of the deep- 

 sea dredging in an official book which was called the Station 

 Book. 



Von Suhm had been, when a boy, an ardent collector of 

 birds, and some of his first publications were on European birds. 

 He took constant interest in birds during the voyage, and his 

 last excursion on shore was at Hilo, Hawai, in pursuit of the 

 interesting endemic birds of the islands with a native guide. 

 Almost the last notes that he wrote were some on the Sandwich 

 Islands relating especially to the birds. 



I sat with him during the whole of the " Challenger " voyage, 

 working day after day with the microscope at the same table. 

 I am very greatly indebted to him for information in all 

 branches of zoology, and especially in the matter of zoological 

 literature, of which he had a most comprehensive knowledge. I 

 also learnt very much from him in the way of method, and I 

 feel that I shall always remain indebted to him for a decided 

 push on in my general scientific training. 



He was a most indefatigable worker. He was full of hope 

 for the future, and, no doubt, could he have published his 

 journal himself, would have established a reputation as a man of 

 science, which would have been far greater than that winch he 

 most deservedly possessed at the time of his death. 



The harbour of Papeete in Tahiti was reached on September 

 18th.
