Studies of Tasmanian Cetacea. Part IV. Delphinus delphis (the common dolphin)

摘要

The dolphin is common around the Tasmanian coastudand in the estuaries of the larger rivers, sometimes ascendingudthem for many miles from the open sea. During theudcurrency of the Easter Camp of the Tasmanian Field Naturalists'udClub at Port Arthur we were fortunate in observing a large number of dolphins in Maingon Bay, Tasman'sudPeninsula. There were several hundred dolphins in the bayudand their evolutions in the surf were watched with interestudby many of the Naturalists for the greater part of EasterudMonday.udAlthough it is here assumed that the modern methodudof reducing all the smaller dolphins to a single speciesud(that of the type) is a more or less wise one, it must stillududbe claimed that such a proceeding leaves certain outstandingudfacts unaccounted for. Includes illustrative plates.
