﻿A PRELIMINARY REPORT UPON THE SPECIFIC IDENTITY 



OF THE CESTODE PARASITES OF MAN IN THE 



PHILIPPINE ISLANDS WITH A DESCRIPTION 



OF A NEW SPECIES OF TjENIA. 



By Philip E. Garrison. 1 

 {From the Biological Laboratory, Bureau of Science, Manila, P. I.) 



INTRODUCTION. 



The present paper embodies the results of careful determinative work 

 upon such cestode material as has been collected for the Helminthological 

 Collection of the Philippine Bureau of Science and is intended as the 

 first of three or four papers, to appear as soon as the specimens in other 

 groups can be properly worked over. 



It is my purpose to endeavor to present in a systematic way some 

 definite knowledge with regard to the specific identity of the more 

 common animal parasites of man in the Philippine Islands. While the 

 primary object of these publications is to clear the field for future work 

 in the localities in question, rather than to present new helminthological 

 findings, they naturally will include the description of forms coming to 

 my attention in this preliminary work which seem to justify the establish- 

 ment of new species or other systematic groups. 



Our present knowledge of Philippine helminthology has been derived 

 from a few determinations made by professional zoologists upon material 

 received from the Islands, from the reports of infections in Americans 

 recently returned from a more or less prolonged residence in the Philip- 

 pines, and from the work of resident medical scientists. While the 

 information supplied by these sources has in many cases been lacking in 

 the positive and precise identification of the parasites reported, it has 

 established with reasonable certainty the presence in the Philippines of 

 several forms already known in other parts of the world and has included 

 the description of two new species of human entozoa, besides contributing 

 considerable knowledge concerning the general prevalence of animal 

 parasites in the Islands. 



A summary of any results already published will be given in the con- 

 sideration of each genus and species reported.
