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 
a leurobranchs and Lamellariidae (Marseniaden) of the world, and various 
i other groups. :

No ‘Erster Theil’ was ever published ; Semper’s account of his travels

in four papers in Z. wiss. ZoolA Owing to the misplaced ingenuity of 
| Bergh and his publisher the work is subdivided in a manner which leads to
