formulas in which we collected the type. Again I did not get a 

 single 00300, and not a proper rubella, although some of them had 

 a tendency to rubella. 



Out of 250 si)ccimens collected, 150 were type with five hands, 

 and rather more than half of these were albolabiafa, although I think 

 I must have taken more of the var. albolabiata, simply because they 

 had white mouths. 



Out of those I took, sixty specimens were 00345, and of these 

 twenty-two were albolabiata ; of the rest, a few were 10345, with both 

 dark and white mouths, and the remainder were bandless, nearly half 

 of them being albolabiata, some almost pure white and some with a 

 tendency to purple. The most striking thing about the specimens of 

 albolabiata is that they look so much like H. hortensis, especially as 

 they are only rather small shells, and about the size we find plenty of 

 H. hortensis in England, and if they had been found by themselves 

 they might easily have been put down as that species. Amongst 

 them I found two specimens alive, with a very long extension of the 

 mouth, which I believe to be due to their being old shells that had 

 lived for a long time through the winters being mild, and had each 

 year added a little more to the mouth. 



One day whilst at Bunbeg we went across by boat to the peninsula 

 of Carrickfin, opposite Bunbeg, and at the southern end we found a 

 large colony of H. nemoralis var. citrinozonata. I have never found 

 this variety at all common, although I have taken specimens at 

 several places, but never more than two or three in a locality ; but 

 at Carrickfin our party found over one hundred specimens, a good 

 many of them in very fine condition. Owing to this variety being so 

 very uncommon, we collected more of it, and neglected the others, 

 although there was here a large proportion again of albolabiata. 

 We also found a good many libellula 00000, with both white and 

 dark mouths. What is the cause of such a colony o{ citrinozonata} 

 I was struck with one thing, and that was that all over the ground we 

 worked there was a quantity of a yellow fungus, like a mushroom, and 

 just about the same colour and size as the shell. Could it be that 

 the fungus is poisonous to birds, and so they did not touch the var. 

 citrinozonatal Along with them we got a few of var. roseozonata 

 as well. 



Another day whilst at Bunbeg we went out to the islands of Inish- 

 meane and Gola. On Inishmeane we could not find any H. nemoralis 

 for a long time, but just before leaving Mr. Wright found some 

 amongst stones and on an old wall. They were mostly rather thin 

 specimens, and more richly coloured than on the mainland. 



On Gola also we found a few very nice ones, and Mr. Wright got
