56 SUMMARY OF CURRENT RESEARCHES RELATING TO 



Protozoa. 



Foraminifera of Galway.* — F. W. Millett has published some 

 notes on Foraminifera collected on the seashore at Galway, by F. P. 

 Balkwill, in 1879-80. Along with Balkwill, he reported on this 

 collection in the Journal of Microscopy and Natural Science, iii. 

 1884, but as the plates came out roughly, he has had the original draw- 

 ings reproduced by photogravure. The classification and nomenclature 

 have been brought into accordance with modern researches. Among 

 the more interesting forms the following may be noted : — Spirilondina 

 acutimargo, Milwlina auberiana, Ammodiscus shoneanus, Trochammina 

 plimta, Lagena clathrata, L.fimbriata, Pulvinulina patagonica, Lingulina 

 carinata (in Silvestri's genus Ellvpsolingulind). 



Tertiary Foraminifera of Victoria.! — F. Chapman gives an account 

 of the Foraminifera in the Balcombian deposits of Port Philip. He 

 comments on the abundance of Foraminifera in many of the clays and 

 limestones of the Victorian Tertiary strata, and on the gigantic size and 

 redundant growth of many of the species — an index to the congenial 

 life-conditions. 



Physiology of Pulsating Vacuole in Infusoria.} — A. Kanitz dis- 

 cusses the relation of temperature to the activity of the pulsating 

 vacuole in Infusoria. The reactions to temperature are such as to render 

 physical explanations, e.g. osmosis, insufficient. They appear to conform 

 to the R.G.T. rule (Reaktionsgeschwindigkeit Temperaturregel), accord- 

 ing to Avhich a raising of the temperature 10° increases the reaction speed 

 from two to three times. The results obtained with the pulsating 

 vacuoles of different Infusoria in accordance with this rule are most 

 readily explained in relation to chemical processes. 



New Hypotrichous Infusorian.§ — E. Faure-Fremiet describes a new 

 form, which he makes the type for a new genus, Ancystropodium 

 maupasi g. et sp. n. This form possesses a contractile pedicle, consist- 

 ing of a protoplasmic strand, which carries on its left border seven 

 marginal cilia. The species is a highly differentiated one, adapted for 

 fixation by means of its tranverse cilia. The author considers the 

 question of a possible relationship with the Vorticellida?, but regards such 

 a view as untenable. 



Ichthyophthirius multifiliis on British Roach. || — James Johnstone 

 records the occurrence of this Ciliate upon the skin and gills of roach 

 in Hesketh Lake, Southport. Only the roach were affected, and pike, 

 perch, and eels living in the same water showed no signs of disease. 

 The epidemic produced considerable mortality among the roach for 

 about a month, after which it died out. This appears to be the first 

 record of this Ciliate in British waters. An account of its structure and 

 mode of multiplication is given.
