A series of Reports on the Zoological Results of the Third 

 Tanganyika Expedition 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 ah-eady known from Lake Tanganyika, no 

 fewer than ten specimens of new species belonging to the 

 family Atyidse, including the representatives of two new genera, 

 were obtained. From Lakes Nyasa and Victoria Nyanza only a 

 single species Avas got, the widely-distributed Caridina nilotica 

 {C. wyckii). The absence of this common species from the 

 gatherings made in Tanganyika emphasised the isolated character 

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

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

 There was no ground for I'egarding the Macrura of Tanganyika as 

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

 the groups to which they belonged, the genus Palcemon and the 

 family Atyidae, were characteristically and all but exclusively fresh- 

 water 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 Sponges 

 obtained from Lakes Victoria Nyanza, Tanganyika, and Nyasa. 

 The collection cornprised eleven specimens representing five 

 species, one from Tanganyika being new to science, two others 

 from Tanganyika {Sjjongilla tnoorei Evans and S. tanganyikce 

 Evans) having already been recorded from that locality. Small 

 specimens of a fourth species, viz. Sjjongilla ca7-teri Bowerbank, 

 Avere obtained from the Victoria Nyanza, and a fairly large 

 specimen of a fifth, viz. Spongilla biseriata Weltner, was collected 

 in a swamp bordering Lake Nyasa. 



Included in Mr. Kirkpatrick's I'eport Avere descriptions of tAvo 

 new species and a new A^ariety of FresliAvater Sponges, based on 

 material obtained from the White Nile. 



The Oligochsete Worms Avere reported upon by Mr. F. E. 

 Beddard, F.R.S. They comprised examples of four neAv species. 



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

 Medusae of the genus Limnocnida obtained during the Expe- 

 dition,
