﻿CESTODE PARASITES OF MAN. 539 



which Dr. Strong, Director of the Biological Laboratory, includes the results of 

 over 6,000 microscopic examinations of faeces, only five cestode infections are 

 reported, all with the genus Tcenia, species not noted. Hallock, 5 at Fort Porter, 

 Buffalo, N. Y., reported two' infections with Hymenolepis nana in American 

 soldiers recently returned from the Philippines. Stiles and Garrison, 6 at the 

 Government Hospital for the Insane, District of Columbia, found no cestode 

 infections in making microscopic examinations of the stools of 115 American 

 soldiers who had returned from Philippine service. In 1906, Foster T reported 

 two infections with Hymenolepis nana in American soldiers on duty near Manila. 



During the past nine months there have come to our attention about 

 fifty intestinal infections with cestodes, representing three genera and 

 five species. 



TAENIA. 



Of the fifty. cestode infections about forty were with worms of the 

 genus Taenia. Specific diagnosis from the ova alone was not attempted. 

 Thirty-one specimens of adult Taenia have been deposited in the collec- 

 tion. 



The cases given in the annual reports of the Superintendent of Govern- 

 ment Laboratories and the statement given by Strong in 1901, above 

 noted, appear to be the only mention, at least within recent years, of the 

 presence of this genus in the' Philippines. 



Taenia saginata Gceze, 1782. Twenty-six of the thirty-one Taenia 

 specimens are Tcenia saginata, twenty-two being from native Filipinos ; 

 fourteen possess the scolex and strobila entire, while twelve were deter- 

 mined from the strobila alone. Two other specimens which were received 

 probably belong to this species, but owing to poor preservation the 

 characters could not clearly be made out and the identity is considered 

 doubtful. One worm in the recent state presented a fairly distinct 

 post-suctorial ridge around the scolex, resembling that described for 

 Tcenia hominis Linstow, 1902. Further examination failed to reveal 

 any other characters described for that species and seemed to establish 

 the specimen's identity with T. saginata. In all cases presenting any 

 peculiarities which might throw doubt upon the determination, the 

 specimens were studied in stained sections in comparison with material 

 of known identity. 



Tcenia philippina sp. nov. The establishment of this species is pro- 

 posed upon a single specimen obtained in 1905 by Mr. Hare of the Bureau 

 of Science, from a prisoner in Bilibid Prison and placed in the museum 

 of the Bureau of Science without determination. For specific diagnosis 

 and description of type specimen, see pp. 542-550, figs. 1-17.
