new species." The author commenced by stating the grounds upon which 

 it might be considered desirable to retain the suborder Stolonifera, and 

 criticised the views of those who place these Alcyonarians in the suborder 

 Alcyonida. Of the genera that had already been proposed only four could 

 now be retained, namely, Tubipora, Clavularla, Comularia, and Sympodium, 

 and the author proposed to add one more, namely, Stereosoma. The genera 

 Sarcodictyon, Rhizoxenia, Cornulariella, Anthelia, and Gymnosarca must be 

 abandoned, and the species incorporated in the other genera. A description 

 was then given of the new genus Stereosoma, a form found on the coast of 

 North Celebes, distinguished from all other Stolonifera by certain characters 

 of its tentacles and by the absolute non-retractability of its polypes. Several 

 new species of Clavularla were then described from North Celebes, Diego 

 Garcia, and Australia. This was followed by a summary of all the species 

 of the genus known to science. 



Mr. F. E. Beddard read a description of the convolutions of the cerebral 

 hemispheres in certain rodents. The paper referred chiefly to Dasyprocta, 

 Ccelogenys, Lagostomus, Hydrochceras, and Dolichotis, being the genera of 

 rodents in which the brains show the greatest development of convolutions. 



A communication was read from Prof. Collett, containing a description 

 of a new Monkey from S.E. Sumatra, for which he proposed the name 

 Semnopithecus thomasi. 



Mr. H. J. Elwes read the second portion of an account of the Butterflies

A letter was read from Dr. A. B. Meyer, of Dresden, respecting the 

 occurrence of a Monkey, Semnopithecus nemaus, in Hainan. 



A communication was read from the Rev. T. R. R. Stebbing, entitled 

 11 Descriptions of nine new Species of Amphipodous Crustaceans from the 

 Tropical Atlantic." This communication contained descriptions and figures 

 of some new Hyperidean Amphipoda collected by Mr. John Rattray, when 

 on board the 'Buccaneer' at the beginning of 1886. The specimens had 

 been taken in the tropical Atlantic off the west coast of Africa by a series 

 of "tow-nettings" carried on at the expense of Dr. John Murray and 

 Mr. J. Y. Buchanan. 



Dr. Hans Gadow gave an account of the remains of some gigantic Land 

 Tortoises and of Didosaurus recently discovered in Mauritius, along with 

 the bones of the Dodo described in a previous communication by Sir Edward 

 Newton and himself. The remains of the Tortoises were referred to Testudo 

 indica, T. triserrata, T. iuepta, and to two new forms proposed to be called 

 T. sauzicrl and T. soumeirel, the latter being possibly related to the gigantic
