1. Second Report on Additions to the Batraoliian Collection 

 in the Natural-History Museum '. By G. A. Bou-

[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 beginning 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 18.58 '. 

 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 the 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 4692. 63 

 species were added from 1882 to the middle of 1886, and 74 more 

 are enumerated in the jiresent 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 ann. 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.
