SEMPER’S REISEN 
Dr. R. Bergh (1824-1909), whose full name was Ludvig Sophus Rudolph 
Bergh, published a large part of his work on nudibranchs and other 
mollusca in Semper’s Reisen. This work is by no means confined to the 
material collected by Semper in the Philippines, but includes a survey of

& 
Ber: all available material and literature of most groups of nudibranchs, the 1 
u: N pleurobranchs and Lamellariidae (Marseniaden) of the world, and various 4 
: other groups. : ä 
The volumes of Reisen im Archipel der Philippinen von Dr. C. Semper i 
‘all bear the subheading ‘ Zweiter Theil. Wissenschaftliche Resultate '. i 
No ‘ Erster Theil’ was ever published ; Semper’s account of his travels F 
in the Philippines (1858-9865) was not completed, but in part published H 
in four papers in Z. wiss. Zool.! Owing to the misplaced ingenuity of f 
Bergh and his publisher the work is subdivided in a manner which leads to f 
w much confusion in eitation : for example the title pages of the part dealing } 
B } with Bulla, etc., bear the references ® Theil 2, Band 7, Abtheilung 4, 8
