Macroom. One specimen 

 only, but from its recorded 

 distribution it is probably 

 fairly common. 



Youghal. 



Common at Carrigrohane, 

 R. Lee and backwater. 



Recorded by Messrs. John- 

 son and Halbert as 

 "common." Only 2 or 3 

 specimens occurred at 

 Macroom. 



R. Lee, Carrigrohane. 



Youghal. 



Several specimens, R. Lee 

 and backwater, Carrigro- 

 hane, 



Carrigrohane, R. Lee. Ori- 

 ginally taken by Mr. Clear 

 in this river about 1846, 

 although for some reason 

 not obvious it was later 

 (1869) suggested that Mr. 

 Clear's specimens were of 

 continental origin. The 

 re-discovery of the species 

 in the River Lee is there- 

 fore interesting. I took 5 

 specimens in 4 hauls of 

 the net at one particular 

 place. 



R. Lee, backwater Carrigro- 

 hane. Common. 



R. Lee, Carrigrohane, abun- 

 dant in backwater.
