A seiies of Reports on the Zoological Results of the Third 

 Tanganyika Exjjedition conducted by Mr. W. A. Cunnington in 

 1904-05, was read. , 



The Report on the Fishes was by Mr. G. A. Boulekger, F.R.S., 



who stated that the collection consisted of 300 specimens referable 

 to 84 species, 28 of which were new. 



Of Crustacea, reported upon by Dr. W. T. Calman, in addition 

 to the two species already known fi'om Lake Tanganyika, no 

 fewer than ten specimens of new species belonging to the 

 family Atyidfe, including the representatives of two new genera, 

 wei'e obtained. From Lakes Nyasa and Victoria N'yanza only a 

 single species was got, the widely-distributed Caridina nilotica 

 (G. wychi'i). The absence of this common species from the 

 gatheiings made in Tanganyika emphasised the isolated character 

 of the Macruran fauna of that lake. All the species found in 

 Tanganyika and all but one of the geneia were peculiar to the lake. 

 There was no ground for regarding the Macrura of Tanganyika as 

 having any specially " marine" affinities. The other members of 

 the grou])s to which they belonged, the genus Palcemon and the 

 family Atyidte, were characteristically and all but exclusively fresli- 

 watei' animals. 



The collection of Mollusca, reported upon by Mr. Edgar A, 

 Smith, I.S.O., contained examples of 33 species, one of which was 

 new. 



Mr. R. Kirkpatrick reported on the Freshwater S])onges 

 obtained from Lakes Victoria ]S"yanza, Tanganyika, and Nyasa. 

 The collection comprised eleven specimens representing five 

 species, one from Tanganyika being new to science, two othei-s 

 from Tanganyika (^Sjiongillci moorei Evans and S, tavganyikcn 

 Evans) having already been recorded from that locality. Small 

 specimens of a fourth species, viz. Spongilla carte7-i Bowerbank, 

 Avere obtained from the Victoria Nyanza, and a faiily large 

 specimen of a fifth, viz. Bpongilla hiseriata Weltner, was collected 

 in a swamp bordering Lake Nyasa. 



Included in Mr. Kirkpatrick's report were descriptions of two 

 new species and a new variety of Freshwater Sponges, based on 

 material obtained from the White Nile. 



The Oligochjete Worms were repoited upon by Mr. F. E. 

 Beddaru, F.R.S. They comprised examples of four new species. 



Mr. R. T. GuNTHER exhibited and made remarks on the 

 Medusa^ of the genus Limnocnida ol)tained during the Expe- 

 dition.
