444 Carpenier : Zoology at the British Association, 



nington, who described his recent expedition to Lake Qurun, 

 in Upper Egypt ; noteworthy results were a fresh-water 

 gymnolaematous polyzoon and a fresh-water medusa with its 

 hydroid. Professor W. A. Herdman contributed ' Notes on a 

 recent visit to the Ceylon Pearl Bank/ and Professor G. H. 

 Carpenter gave an account of newly-discovered Arctic and 

 Antarctic Collembola. 



On Tuesday, September 8th, the Section held a joint 

 meeting with 1 (Physiology) to consider the biological and 

 pathological relations of blood parasites, especially Trypano- 

 somes. Mr. R. Newstead contributed an account of the Biono- 

 mics of Tsetse flies, while Messrs. J. E. S. Moore and A. Breinl 

 described some newly-discovered features in the life history 

 of the Trypanosoma of sleeping sickness. When the flagellate 

 parasites disappear from the blood, they are present as small, 

 non-flagellate cells in the spleen and marrow. Drs. Breinl and 

 Hindle gave a paper on the life history of Piroplasma camis. 

 Besides the ordinary amoeboid and ' twinned ' forms in blood 

 corpuscles, they detected two flagellate forms — one round, the 

 other oval, in the plasma of the vertebrate host. But they 

 had no results as to the life-cycle in the tick. 



The burning question of Nomenclature was brought before 

 the Section by Mr. G. A. Boulenger, F.R.S., of the British 

 Museum. He protested against those upholders of the ' law of 

 priority ' who supplant well-known names used in classical 

 treatises, and a resolution against such changes was carried 

 unanimously. 



The Section did not meet for business on Saturday, 5th 

 September, but a party of seventy paid an early visit to the 

 Zoological Gardens in Phoenix Park, where the Council of the 

 Royal Zoological Society entertained them at breakfast in the 

 Haughton House. This gathering was generally admitted to 

 have been very enjoyable, and much interest was afterwards 

 displayed in the fine set of animals on view, especially the 

 three Chimpanzees at present in the Anthropoid House, two 

 well-grown litters of Lion-cubs, and the Pacific Sea Lions and 

 Irish Grey Seals in their new pond. In the afternoon, by kind 

 invitation of Rev. W. S. Green, a party of zoologists travelled 

 to Kingstown, and boarded the new fisheries cruiser ' Helga.' 

 The vessel steamed out towards Lambay, and practical demon- 

 stration of the admirable gear and apparatus for collecting and 

 preserving marine specimens was given.
