1903.] ENTO-PARASITES OF THE " SKEAT EXPEDITION.' 155 



SPOROZOA. 



Order Sarcosporidia Balbiani. 



Several specimens of this order were found amongst the muscles 

 and the tissues at the base of the tongue of a Bos bubalis killed 

 at Kwala Aring. Dr. von Linstow has described these specimens 

 as a new species — Balhiana {Sarcocystis) siamensis — in the article 

 mentioned under the ISTematoda. I have figured these life-size, 

 on PI. XVI. fig. 12.
