Dr. W. A. CuNNiNGTON, F.Z.S., I'ead a report on the Brachyurous 

 Crustacea of the Third Tanganyika Expedition. The collection 

 contained specimens from both Nyasa and Tanganyika. Including 

 a few individuals which had hitherto passed without notice in the 

 collection of the British Museum, there were now on record three 

 species fi-om Nyasa and five from Tanganyika. Of these species, 

 three were described as new. The forms from ISTyasa all belonged 

 to the widely distributed subgenus Potamonautes ; but while two 

 species fi'om Tanganyika also belonged to that subgenus, the lake 

 contained three species belonging to the remarkable endeinic 

 genus Platythelpkusa A. Milne-Edwards. The suggested marine 

 appearance of P. armata was considered to be only superficial, 

 and the peculiar character of the Brachyuran fauna of 

 Tanganyika could be explained on the grounds of a prolonged 

 isolation of the lake. 



Mr. F. E. Bbddard, F.R.S., described two new species of 

 African Oligocheete Worms of the genus Microchcetus belonging 

 to the collection of the Ohristiania Museum.
