ADDITIONS AND COEKECTIONS TO THE 'INDEX 

 ZOOLOGICUS' OF C. 0. WATERHOUSE. 



By E. Bekgroth, C.M.Z.S. 



Mr. C. 0. Waterhouse has recently published* a supplement 

 to the 'Index Zoologicus,' compiled by him and edited by Dr. 

 D. Sharp in 1902. In this supplement about two hundred and 

 fifty omitted names are recorded, and in the supplement given 

 below about three hundred names are added. Unfortunately I 

 have in many cases been unable to give the date of the publica- 

 tion, but only names published before 1901 are included. Doubt- 

 less many hundred names are still unrecorded — particularly in 

 the Crustacea, Vermes, Ccelenterata, Spongiae, and Protozoa — 

 and I am convinced that students of these classes would easily 

 be able to fill the gaps. Among the fossil genera there are also 

 certainly very numerous omissions.
