igiS. HuGGiNS. — Limnaeae of West Cork Alpine Lakes. 125 



Lough " B," Caha Lakes, 1,450 feet, is inhabited by a 

 very beautiful race of L. pereger, extremely thin, 

 glossy, and closely striated, with short, perfectly formed 

 acute spires. A very clean and attractive shell. 



Lough " C," Caha Lakes, 1,500 feet, contains L. invokita, 

 almost exactly similar to the race in Barley Lake, but 

 slightly more square-shouldered and deeply intorted. 



Lough " D," Caha Lakes, 1,550 feet : — L. praetenuis, 

 almost all intorted, with narrower mouth and less 

 suture than the Lough Nagarriva form.

Lough " E," Caha Lakes, 1,500 feet :— Nil. 



Lough " F," Caha Lakes, 1,500 feet : — L.pereger, a rough, 

 thicker, more coarsely striated form, many specimens 

 were decollated and a few^ slightly intorted.

 an extremely bright glossy form, many specimens were 

 as deeply intorted as any I have seen from Lough

Lough " H," Caha Lakes, 1,500 feet : — L. pereger, a round

 instances. . Almost all the specimens were damaged
