MOLLUSCA IN THE NORTH OF SCOTLAND 277 



The St Fergus Canal is now a thing of the past, and the 

 Aberdeen Canal is now occupied by a single track of railway 

 laid along the dried-up bed of the canal throughout its 

 entire length. 



The Torry district is now all laid out in streets and built 

 upon, and the Den of Rubislaw, which yielded Acanthinula 

 lamcllata and other good shells to Macgillivray, is now a 

 residential suburb of Aberdeen and all built upon. The 

 hollows between Aberdeen and the Spittal are all either 

 drained or filled up and used for building purposes, and 

 there are no ponds or ditches now in existence there. 



Mr Simpson told me that Macgillivray's and Dawson's 

 collections of mollusca are in the Museum of the University 

 of?=y.ierdeen, to which I paid a visit. Unfortunately for me 

 Profs. Thompson and Trail and all the staff were away on 

 holiday. The curator in charge showed me all the land and 

 fresh-water molluscan collections that he could find, and I 

 understood him to say that a lady, Miss Arnott, was greatly 

 interested in mollusca, and when she was in Aberdeen went 

 through and rearranged the whole of the mollusca. I found 

 very few examples of British species, and what I did see had 

 been fastened down to new strips, and in a number of cases 

 had no data, either as to locality or date of collection. If 

 the specimens I saw are the only examples, then it may be 

 said that the Macgillivray and the Dawson collections have 

 ceased to exist; and if they had been carefully retained, they 

 would have been of the utmost value for local record. 



I noted the following : 



Helix nemoralis, St Cyrus, Kincardine, Th. North, 1844. 

 Helix nemoralis, St Cyrus, Kincardine, Th. Keith, 1844. 

 Helix nemoralis, vars. rubella and libel lula, without bands. No 



locality or date. 

 H hortensis, sand-banks, Inverugie, no date. 

 Hyalinia crystallina, Cruden, no date. 

 Hyalinia nilidula, Cruden, no date. 

 Hyalinia alliaria, Cruden, no date. 



These specimens are not that species, but some arc If 



cellaria, and others H niiidula, varnished. ><^\C>f^x 



Ena obscura, St Fergus Links, no date. A/^or^" <"
