1890.] BATRACHIAN COLLECTION IN THE BRITISH MUSEUM. 323 April 15, 1890. G. A. Boulenger, Esq., F.Z.S., iu the Chair. The following papers were read : — 1. Second Report on Additions to the Batracliian Collection in the Natural-History Museum '. By G. A. Bou-lenger. [Eeceived March 18, 1890.] (Plates XXV. & XXVI.) Our knowledge of the species of Batrachians increases rapidly. After considering carefully every description that has been published since the begimiing of 1882, I find that as many as 1119 apparently valid species are known at present, viz. 960 Ecaudata, 122 Caudata, and 37 Apoda. The collection in the British Museum keeps pace with this increase, as testified by the following list of additions received during the last four years. In fact, the rate of increase has steadily risen since the collection of Frogs was first put in order by Dr. Giinther in 1858 ^ The number of species then represented in the Museum was estimated at 214 (1691 specimens). In a report published ten years later by Dr. Giinther^ the number had risen to 313. In tlie second edition of the Catalogue, prepared by me and issued in 1882, the number of species was given as 522, and the number of specimens -1692. 63 species were added from 1882 to the middle of 1886, and 74 more are enumerated in the present report. So that the Museum possesses at present examples of about 660 species of Frogs, illustrated by over 6900 specimens. Thus we see that the increase in the number . of species represented in the Museum has been at the rate of 10 per annum from 1858 to 1868, of 15 per ann. from 1868 to 1882, of 16 per aim. from 1882 to 1886, and of 18| per ann. from 1886 to the present day. The number of Tailed Batrachians in the Collection is now 85 species and about 1340 specimens ; of Apodals, 29 species and 156 specimens. I.
