RESEARCH COLLECTIONS 75 



While many of the major divisions of the several classes of parasitic 

 worms are still unrepresented, we already have 130 species of 76 

 different genera of Nematoda, eight species of eight genera of Acan- 

 thocephala, 43 species belonging to 22 genera of Cestoda and 21 

 species of 16 genera of Trematoda. Even this small collection con- 

 tains the type specimens of about 20 recently described forms. 



Awaiting study and identification are three very extensive collec- 

 tions made by Dr. Ralph Wheeler in Assam, by Mr. Loveridge in 

 Tanganyika and by Dr. Sandground in his recent trip through 

 Rhodesia and Mozambique. Because of the recent affiliations with 

 the Department of Tropical Medicine in the Medical School, the 

 collections are growing satisfactorily in their representation of 

 parasites of economic importance.
