INTRODUCTION. 



In a special report submitted to the Surgeon-General of the Army in 

 May, 190G, and published in the American Journal of the Medical 

 Sciences in September of that year, we described a new blood filaria of 

 man, to which we gave the name Filaria philippinensis sp. nov. because of 

 its occurrence in a native of the Philippine Islands. 



We considered that this filaria represented a new species, and that it 

 was probably the only one indigenous to these Islands; a new species, 

 because of its morphology, lack of periodicity and the rarity of fila- 

 riasis in the Philippines; the only indigenous one, because the previous 

 descriptions of the filaria? observed in natives of these Islands contained 

 nothing which would exclude the possibility that the observers might have 

 been dealing with Filaria philippinensis. 



When our preliminary communication regarding this parasite was 

 written we had seen but one case of infection with it, but since then we 

 have had the opportunity of studying four additional cases, all in natives 

 of the Philippine Islands. To Doctor Albert L. Miller, contract surgeon,

 Charles F. Craig, first lieutenant and assistant surgeon, United States Army, con- 

 stituting the United States Army Board for the Study of Tropical Diseases as 

 They Occur in the Philippine Islands.
