THE COLLECTION OF SPONGES 



BY 



ELISABETH DEICHMANN 



There are about three hundred trays of dried specimens of sponges, 

 and about five hundred and fifty more of these are kept in alcohol. 

 The "Blake" material from the West Indies, treated by P. Schmidt 

 in 1879, contains about fifty types. The remaining part of the collec- 

 tion consists of the material which von Lendenfeldt used for his large 

 monograph on the Pacific sponges, secured by the "Albatross" 

 1904-05, but of this collection the types are in Washington. There 

 are a number of common forms from various parts of the world. 

 Few additions have been made in the last twenty-five years, and the 

 collection needs a specialist who will build it up.
