EXPLORATIONS IN CAPE REGION. 765 



But beginning with the expedition of 1891, the collec- 

 tions of lower animals became so large that it was decided 

 by the President of the Academy, H. W. Harkness, and 

 the governing Council, to distribute collections to various 

 specialists for descriptions in the Proceedings of the 

 Academy. This was done in 1892, 1893 and 1894. T'he 

 conditions upon which collections were thus distributed 

 for scientific work were very liberal and regarded prin- 

 cipally three points: 



1. The MS. of the respective authors regarding the 

 collections sent them should be published by the Califor- 

 nia Academy of Sciences. 



2. All types* to be deposited in the collections of the 

 California Academy of Sciences. 



3. The respective investigators to retain a set of du- 

 plicates, the first set always going to the Academy. 



Under the above conditions the collections were dis- 

 tributed and worked up as follows. References, unless 

 otherwise specified, are to Proceedings California Acad- 

 emy of Sciences, second series. 



Protozoa. — A large material for the study of parasitic 

 protozoa was collected.

Oligoch^ta or Land Annelids. — A very large col- 

 lection of this class of worms in alcohol is being worked 

 up by the writer. Very great interest is attached to this 



^As this paper is intended also for non-specialists it may not be un- 

 necessary to state that with " types " are understood one or more speci- 

 mens of any species upon which the first description of the species was 

 based. The great scientific value of types is well understood by natur- 

 alists and every scientific collection is chiefly valued according to the 

 "types " it contains. The types will always retain their scientific value, 

 no matter how common will be found the species to which they belong. 

 A perusal of the papers describing the fauna of Baia California will show 

 the great number of types thus possessed by our Academy.
