The above records are almost all from the neighbourhood 
of Belfast and are of great interest to a student of the local 
Mollusca. I feel sure, however, that there are a few cases 
of misidentification to be dealt with. 
Interesting or Doubtful Records contained in the 
MS. 
Helix Vortex. I think this must be referred to Planorhis 
spirorbis, L., var. leucostoma, Millet, rather than to 
Planorhis vortex, L. The former shell is abundant in 
the habitats, such as the Bog Meadows, mentioned by 
Templeton and has been frequently confounded with 
Planorhis vortex. 
Helix Cornea. This can scarcely be Planorhis corneus, L. It 
is more than likely that Templeton intended to record 
Planorhis carinatus, Miiller, or P. umhilicatus, Drap. 
Mya margaritifera. No subsequent writer mentions this 
shell as found in the Lagan. There is no need to doubt 
the record however. 
Turho Perversus. It is strange that Templeton should record 
Balea perversa and not mention the much more common 
Clausilia hidentata. Yet since he states that his T. 
perversus has " the aperture without teeth" there can 
be no doubt that it was Balea which he referred to, 
unless he had only seen young shells of Clausilia. 
Helix planorhis. This probably refers to Planorhis um- 
hilicatus, Drap., which is common in the coastal 
marshes between Belfast and Holywood. 
Helix paludosa. It is strange that Vallonia pulchella 
( =Helix paludosa of Da Costa) could be found com- 
posing the covering of caddis -worms, yet this species is
