ing the parasite as a result of eating infected 
snails. In mice, the larvae of lungworms 
migrate to the musculature, where they be¬ 
come encysted (Van Volkenberg, 1937). 
The tapeworm, T. taeniaeformis, is known 
to utilize rats or mice as intermediate hosts; 
the infective larval forms, "bladder worms," 
are commonly found in the liver of these 
rodents in Hawaii. The tapeworm, D. cani¬ 
num, utilizes fleas or lice as an intermediate 
host (see parasites of dogs). 
ARTHROPODS 
The cat flea, Ctenocephalides felis 
(Bouche), and the sticktight flea, Echidno- 
phaga gall mace a (Westwood), are common 
on cats in Hawaii; the former is also com¬ 
monly found under houses frequented by 
cats. The biting louse, Felicola suhrostrata 
(Nitzsch), has been collected from cats 
(Zimmerman, 1944).

Parasites of Rabbits 
Very little is known about parasites of 
rabbits in the Islands. Liver coccidia, Eimeria 
stiedae Lindemann, have been noted by the 
writer on several occasions. The scab mite, 
Psoroptes communis Furstenberg (Pember¬ 
ton, 1946), which is commonly found in 
the ears, has been reported from rabbits.
