THE following notes of identification, believed to concern 

 for the most part new helminthological species, have been 

 made in the course of study of the parasites enumerated in 

 the synoptic article upon parasites in this journal in the 

 pathological laboratory of the University of Pennsylvania. 

 The specimens upon which the descriptions are based have 

 been obtained for the most part from animals of the collec- 

 tion of the Philadelphia Zoological Gardens which came to 

 autopsy in the laboratory of the Gardens at the hands of 

 Drs. Fox and White, who transmitted them for identification 

 to the first-named writer. While most are new species, at 

 least one has been included which has been previously known, 

 but is here considered because it seems to present special 

 variations. 



In all cases where the material permits, types of these 

 parasites will be placed in the collection of the Academy of 

 Natural Sciences in Philadelphia, as well as in the Patho- 

 logical Museum of the University of Pennsylvania.
