Very few species are knownand they have only been found as yet in Australasian seas, or, morespecifically, about Tasmania. Most of the species—until recently more than all the other Pedicu-lates—have the body oval with a tumid abdomen; the mouth is quitelarge, and the palate dentigerous; the pelvic bones are rather elon-gated, and the second and third dorsal spines are distant or slightlyconnected and not constituents of a true fin. The group or subfamilyis known as the Antennariinse and includes the genera Ptero-phryne, Antennaritis, Histiophryne, Saccarms, and several all of the species, however, belong to the genus Antennarius. The most specialized of the Antennariids are trenchantly separatedfrom the others by having the head cuboid and the first dorsal fin. ^^^^^mm^ Fir;. 10.—A chaunacine Antennariid ((linnnax pictus).

Only one genus—Chaimax^s known. The most conspicuous of the Antennariids are mostly confined tothe coralligenous seas, and by far the largest number belong to thegenus AntennaHus. The only other genus equally well known isPterophryne, whose chief home is the sargasso meadows of the highseas. These are the only ones that need to be noticed at length; i\\Qyare indeed the only ones whose habits are even tolerably well known. THE CERATIIDS. The family of Ceratiids, or deep-sea anglers, has been constitutedfor a number of deep-sea Pediculates distinguishable at once by theabsence of ventral fins and the robust body. There is considerablevariation in form, but most a
