Mac.) Common in ditches, &c. around the Loch of Spynie, and 

 throughout "the featureless flat" (Duffus). 



Contorted Coil-shell, Planorbis contortus. In the same localities 

 as the last species. 



Shining Lenticular Coil-shell, Planorbis nitidus. In canals and 

 ditches around the Loch of Spynie; Order Pot, Mr. Martin; near 

 Lesmurdie Cottage, Mr. Macdonald. 



Wandering Mud-shell, Limnceus pereger, {Lymnea lutea and L. 

 limosa, Flem.) Very common. Mr. Martin states that he has often 

 been amused in watching the movements of this species in the 

 old canal north of Inchbroom, when hundreds of these creatures were 

 seen sailing from one end of the canal to the other, foot uppermost. 

 Their wandering propensities were always exhibited when they had 

 the advantage of a favourable wind, and when the wind was westerly 

 those that were at the west end made a voyage to the eastward ; and 

 again, when the wind changed, a large body of them were seen return- 

 ing. What their motives were in this movement it is difficult to say, — 

 whether in quest of food, on visits of friendship, or on pleasure excur- 

 sions. When they had fairly started on their voyage they resembled 

 a fleet of herring-boats in miniature. The shells of L. pereger 

 in this canal, adds Mr. Martin, are larger than any that he has seen in 

 the North. 



Little Mud-shell, Limn&us truncatulus, {L. fossaria, Flem.) Fre- 

 quent. Linksfield, and in pools near Loch of Cotts, Mr. Martin ;

Marsh Mud-shell, Limnceus palustris. In ditches near the north 

 gate of Innes House, Mr. Martin ; in a small grassy puddle between 

 Burghead and Cummingston, Mr. Murray; ditch near Castle of 

 Spynie, Mr. Macdonald.

 Lhanbryde, where large varieties are found, Mr. Martin; Linkwood
