 average of about 158.

FiGURK 8, d 



A single trematode came from the intestine of one of three Galeich- 

 thys niilherti (Cuvier and Valenciennes) on July 31. 



LECITHOCHIRIUM SYNODI Manter

 One of three Felichthys felis (Linnaeus), on July 31, bore five 

 trematodes in its intestine. 



LECITHOCHIRIUM sp. 



A young trematode was found in a clam, Noetia ponderosa (Say), 

 on July 26. This is perhaps the young of L. microstommn Chandler. 



HISTEROLECITHA ELONGATA Manter 



In 10 Mugil cephalus Linnaeus, on July 3, 10 specimens of this
