Abstract
THE tailed Batrachia have during recent years attained an increased importance zoologically, by appreciation of the fact that in respect to many features in which their living representatives present a simplification of organisation they are retrograde. While but one of them possesses a complete maxillo-jugal arch, none are pentadactyle in both fore- and hind-limbs; and the unexpected has been reached, in the discovery that there are no fewer than ten species of six genera which are lungless, and that in some of these respiration is largely buccal or pharyngeal, and may even, in all probability, involve the tips of the toes, as in Autodax and species of other known genera.
