Details experiments in attempting to cause Margaropus annulatus to develop on 
horses, mules, asses, rabbits, dogs, and cats. On the last a specimen developed to 
the adult stage, but did not engorge. Shows that under certain conditions the cattle 
tick can reattach after being artificially removed. Refers to recent European investi- 
gations that show that Ixodes ricinus transmits European piroplasmosis of cattle, 
and suggests the possibility that Margaropus annulatus may transmit its disease in 
the nymphal or adult states.
