20*^^ March, 1888. — Mr. G. A. Boulenger, F.Z.S., read a note on 

 the classification of the Ranidae, in which, after speaking of the difficulty 

 hitherto experienced in dividing this large group satisfactorüy , he called 

 attention to Peters' s discovery that in certain forms a small additional pha- 

 lanx is present between the ultimate and what is normally the penultimate 

 phalanx. The author therefore proposed to separate the family Ranidae into 

 two groups, according to the presence or absence of this peculiar digital 

 structure. — Mr. G. B. Sowerby, F.Z.S., gave the description of sixteen 

 new species of Shells, amongst which were two species of the genus Lima 

 from Hongkong and Japan ; a remarkable species of the rare genus Malletia 

 from the Bay of Bengal ; a very distinct species of Cypraea from Japan ; and 

 one of the largest species yet known of the genus Columbella. — Mr. F. E. 

 Beddard, F.Z.S., read some notes on a freshwater Annelid, of which he 

 had obtained specimens from a tank in the Society's Gardens. Mr. Beddard 

 referred these specimens to a new species of the genus Aeolosoma, which he 

 proposed to call Ae. Headleyi. — Prof. Newton, F.R.S., communicated 

 (on behalf of Mr. Scott Barchard Wilson) the description of Chloridops, a new 

 generic form of Fringillidae, based on a specimen obtained on the west coast 

 of the Island of Hawaii, Sandwich Group, which he proposed to name CJilo- 

 ridops koua. Unfortunately the single example yet obtained was of the female 

 sex. — P. L. Sclater, Secretary.
