NO. 14 MANTER: DIGENETICTREMATODES OF FISHES 445 



It is not certain that members of the Aporocotylidae are limited to 

 the blood of their hosts. P. tropicum was collected from washings of the 

 coelom and apparently once from the intestine. Since the host had been 

 dissected, the small flukes might easily have been in the blood vessels. 

 But the writer has collected numbers of Deontacylix ovalis Linton from 

 the coelom of the host even when the fish had been carefully opened. 



HOST LIST 



This list contains only those species of fishes from which trematodes 

 were collected. The number in parentheses following the name of the 

 host indicates the number examined. The number following the name of 

 the parasite indicates the number of host specimens from which the para- 

 site was collected. An asterisk (*) following the name of the host indi- 

 cates that the fish was identified by G. S. Myers or E. D. Reid of the 

 United States National Museum. 



Trematodes without author names are species named in this paper. 



For possible convenience, the common names of the fishes usually are 

 given.
