This Uebersicht on pages 165-178 contains a useful bibliography of Bergh’s work on 
mollusca, listing the species described. By a eurious error, no doubt due to a shufllo 
of tho 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 Oyerce 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. Ono 
paper, his last, is to be added to make the list complete: Appendix, in Schepman, 1908, 
Prosobranchia, Sihoga Exp. 49 (i), 99-107. ;
