216 Genus Ixodes 



descending almost perpendicularly in tarsi 1-3, and with a slight 

 slope in tarsus 4. 



Described from (N. 270) 2 $s taken from a Californian grey squirrel, 

 King's river, California, vn. 1896 (V. L. Kellogg's coll.), and (N. 992) 

 1 % from Procyon lotor, at Mt Lehman, British Columbia, Canada, 

 I. 1910 (S. Hadwen). The two Californian specimens, which we were 

 unable to identify, were sent to Banks, who recognized them as a species 

 he has since described very briefly as /. texanus, from a raccoon, Live 

 Oak County, Texas (Mitchell and Bishopp).
