ANIMALS WHICH LIVE ON OR WITHIN GROUSE 205 



ORDER III. FLAGELLATA. 



XXII. Trichomonas eberihi. 



A small flagellate has been found in the contents of the caeca and 

 intestine of several apparently healthy birds. This flagellate is either 

 the same as, or is only a variety of, Trichomonas eberihi, which has been 

 recorded from the caeca of fowls. 



XXIII. Monocercomonas (sp). 



Forms of this parasite were also seen in the Grouse. They 

 did not occur in very large numbers. 



ORDER IV. SPIROCILETACEA. 



This group includes such forms as cause relapsing fever in 

 man and in fowls, and syphilis in man. The Spirochsetes are 

 dangerous parasites when occurring in large numbers in the 

 blood. Two species of Spirochaetes were found in Grouse, on a 

 few occasions, both species being new. 



XXIV. Spirochceta lagopodis (Fantham, 1910). 



This parasite was found in small numbers in the blood of two birds. 

 It caused a slight alteration in the relative constituents of the blood, 

 but was not associated with any specific disease. 



XXV. Spirochceta lovati (Fantham, 1910). 



This species was seen alive and in stained specimens. It occurred 

 in the caeca and intestine of six or seven of the many birds examined, 

 and was not specially associated with disease. 



The protozoal parasites of Grouse mentioned above are 

 described by Dr Fantham in greater detail, with 'illustrations, 

 in the original Report.
