recorded by Mr Eoebuck in his paper referred to above. 

 When Mr Eoebuck's letter reached me, I was about to start 

 for a natural history ramble in Clackmannanshire, where 

 some of the woods I had made a note of are situated, and 

 the afternoon of that day (3rd September) found me at a 

 particular spot I had in view in the extensive pine woods 

 known as Clackmannan Forest. Here I soon had the good 

 fortune to discover what I was in search of On the under- 

 side of almost the first rotten branch lifted was a small 

 yellowish Limax, which there could be little doubt was the 

 long-looked for L. tenelhcs. A couple of hours close searching 

 yielded nine in all. One was on a red-topped fungus, 

 Bussula emetica, but most of them were under chips of wood 

 and pieces of bark lying on the ground beneath the fir trees. 

 The largest specimen measured 37 mm. when crawling at 

 full stretch ; 25 mm. was about their average length. Three 

 of them have been shown to Mr Eoebuck, and he has con- 

 firmed my identification. They all belong to the waxy- 

 yellow variety to which Held gave the name cereus, and 

 which is apparently the type of the species. A piece of 

 white paper drawn across the body of one was stained pale 

 gamboge- yellow by the mucus. A colourless slime was 

 given off by the foot-sole. The only other slugs met with 

 in the wood were about an equal number of Arion suhfuscus, 

 and one A. mininucs. 



Limax tenelhcs will doubtless be found in the course of 

 time in other localities within the " Forth " area, but I do 

 not think it can be common in the district. At any rate, 

 since finding it in Clackmannan Forest, I have looked for 

 it without success in a number of likely woods in the 

 Lothians, Stirling, Fife, and Kinross. In the meantime, 

 Mr Eoebuck has received it from near Aberdeen, near 

 Dunkeld, and Epping Forest, thus proving it to have a 

 very wide range in Britain.
