Hood — On the Rotifer a of the County Mayo. 697 



NOTES ADDED IN PRESS. 



Since the preceding paper was written I have paid a fifth visit to 

 the Co. Mayo, in June, 1895. This excursioa has enabled me to add 

 two species, and two only, to my list of West Irish Eotifera. 



Stephanoceros JEichhornii, Ehr. In Knappagh Lake, June, 1895. 



Callidina parasitica^ Giglioli. Abundant on ^sellus aquaticus and 

 Gammarus, sp., in streams near Westport, June, 1895. 



Note by W. T. Calman, Universittj College, Bundee.

 with Professor D'Arcy Thompson, near Eoundstone, Co. Galway, in 

 July and August, 1894. Most of them were taken from small bog- 

 pools among Sphagnum, &c. All the species named, with the excep- 

 tion of Euchlanis subversa, are included in Mr. Hood's list for Co.
