SYNOPSIS OF THE GENERA OP THE SUPERPAMIL Y TEUTHIDOIDBA (FAMILIES TEUTHIDID^ AND SIGANID^). By THEODORE Qllili. Having recently had occasion to inquire into the relations and charac-teristics of the constituents, and into the applicability of the names em-ployed for the genera of the family "Teuthyes" of Cuvier, I was obliged to dissent from the taxonomic views as well as nomenclature most in vogue, and have reached the conclusions embodied in the following synopsis. The changes of nomenclature have invariably been made in obedience to the rules of the British and American associations for the advancement of science. Those who are lawless, or follow rules only when they suit their purpose or convenience, will doubtless disapprove of the changes. The necessity for the changes has been appreciated by Messrs. Jordan, Meek, and Bean, and the first two had independently reached the same conclusion with reference to the Teuthis hepatus.
