Semper’s Reisen, volume 9—Malacologische Untersuchungen 
2Feb. 1904 1 1-55 1- 4 Nudibranchien. 
7Mar. 1906 2 57-115 5-58 Berthella.... Chelyonotus. 
18 July 1908 3 119-178 9-12 Voluta.... Uebersicht. 
This Uebersicht on pages 165-178 contains a useful ee of Bergh’s work on 
mollusca, listing the species described. By a curious error, no doubt due to a shullo 
of the pages of the manuscript, more than two-thirds of the species treated of in tho 
Siboga Expedition report of 1905, which should follow on page 178 are actually printed 
on page 169 (beginning with C'yerce elegans, line 13 from bottom) and page 170, and the 
papers of 1906 and 1907 on page 171 were no doubt intended to end the list. One 
paper, his last, is to be added to make the list complete: Appendix, in Schepman, 1908, 
Prosobranchin, Siboga Exp. 49 (i), 99-107.
