Poronotus triacantkus — Continued. 
the market in fish traps; also taken in the 
seine. The young are often observed swim- 
ming under jellyfish. A young specimen 
taken with the dredge at Fish Hawk station 
7740. 
Spawns in June. — Bumpus. 
Food: Fish. Smaller specimens were found by 
Dr. Linton to contain copepods, annelids, and 
small fish, and in September principally 
amphipods. 
Parasites : (Linton) — Acanthocephala — Echino- 
rhynchus acus, E. sagittifer. Nematodes — 
Heierakis sp., Ichthyonema sp., Lecanocephalus 
annulatus, immature nematodes. Cestodes — 
Dibothrium angustatum, Otobothrium crenacolle 
(cysts), Rhynchobothrium bulbifer (cysts), R. 
longispine (cysts), Scolex polymorphus (larvae), 
Tetrarhynchus bisulcatus (cysts), T. erinaceus 
(cysts), T. sp. (cysts). Trematodes — Disto- 
mum gulosum, D. sp., Microcotyle sp., Monos - 
tomum sp. Protozoa — sporocyst in liver. A 
parasitic isopod ( Nerocila munda ) has also been 
found upon this fish by Messrs. Linton and 
Osbum. 
The attractiveness of this delicately flavored fish 
for the table is frequently diminished by the 
presence of abundant cestode cysts throughout 
its muscles.
