FEEDING-TRACKS OF LIMAX MAXIMUS LINN. 



By Thomas Steel, F.L.S. 



(Plate xxiv.) 



In Proc. Linn. Soc. London, October, 1913, p. 70, Mrs. Jane 

 LongstaiF, F.L.S. , describes and figures the feeding-tracks of this 

 slug. Some eighteen years ago, I noticed an individual of the 

 same species feeding on the film of green conferva which had 

 grown inside a white enamel bowl used for holding water for a 

 dog. The tracks are very plainly shown by the removal of the 

 green conferva from the white surface. There is no trace visible 

 of the twin scratches at the apex of the individual tracks, seen 

 by Mrs. Longstaff, and given in her illustration. 



Mrs. Longstaff figures only a single row of the tracks, and 

 does not give the scale; and as my specimen shows the sequence 

 of a large number of rows, and also various irregular and return- 

 tracks, it will be of interest. The illustration is from a photo- 

 graph by my son, Mr. W. A. Steel, and is natural size. 



I have deposited the specimen in the Australian Museum, 

 Sydney.
