Moscow, vol. 37, pt. 2, p. 485, pi. 5, 1864. Lernaeolophus sultamis Wilson, Proc. U. S. Nat. Mus., vol. 53, p. 91, pi. 13, 1917. Occurrence.—Fo\mdi on the gill arches of the orange file fish {Alutera shoep-fii) and on the upper jaw inside the mouth of the garfish {Tylosurus maH^im), both hosts captured in Vineyard Sound. Distribution.—From the common grunt {Haemulon plumieri) at Tortugas, Fla. (Wilson). Color (preserved material).—Body a uniform reddish brown. /^e?72^e.—Cephalothorax spherical, divided on the anterior and ventral surfaces into two pads by a shallow median groove, each pad produced ventraUy into three dactylose processes. Posterior end of head armed with one dorsal and two lateral horns, all more or less branched. Walls of the neck and trunk very hard and thick chitin; neck the same diameter through- out, trunk twice as wide. Abdomen on a level with the dorsal surface of the trunk, its lateral processes dichotomously branched, those in the two rows on each side alternat- ing with each other. Rami of legs often broken off, well armed with setae. Total length, 12-15 mm. Remarks.—The distinctive characters of this parasite are the heavy chitinization of the entire body and the two rows of branched processes on each side of the abdomen. These processes are often thickly covered with algae and protozoa and are more profusely branched in the older and larger FiGUBE 293.
