RUN 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 colleeted by Semper in the Philippines, but includes a survey of 
‚ all available material and literature of most groups of nudibranchs, the 
pleurobranchs and Lamellariidae (Marseniaden) of the world, and various 
other groups. 
The volumes of Reisen im Archipel der Philippinen von Dr. C. Semper 
‘all bear the subheading ‘ Zweiter Theil. Wissenschaftliche Resultate ’. 
No ° Erster Theil’ was ever published ; Semper’s account of his travels 
in the Philippines (1858-1865) was not completed, but in part published 
in four papers in Z. wiss. Zool.! Owing to the misplaced ingenuity of 
Bergh and his publisher the work is subdivided in a manner which leads to 
much confusion in eitation : for example the title pages of the part dealing 
with Bulla, ete., bear the references? Theil 2, Band 7, Abtheilung 4, 
Abschnitt 3, Lieferung 1; Abtheilung 4 is also referred to as Theil 5 and 
Lieferung 1 as Heft 5. 
Altogether eight subdivisional names are used : 
Theil 2 (portion) of the whole work, unnecessary, since the first portion was not \ 
published ; s ! 
Band 2, 7, 9 (volume) ® ofthe whole work as published ; 
Band 1, 2, 3 (subvolume) of Bergh’s work in volume 2; 
Theil 1-6 (division) of Bergh’s work in the three volumes 2, Tand 9; 
Abtheilung (section) ; Heft (part) ; Abschnitt (subsection) ; Lieferung (number). 
The following table gives the subdivisions of Bergh’s work.
