The invertebrate fauna of the Hebridean seas is of a northern 
character, although there are a few exceptions, as Phasianella 
pulla. Some species seem to reach their most southern limit in 
the Hebrides, as Lima elliptica, Nucula pygmcea, Trochus gron^- 
landicus. The author has added some very valuable observa- 
tions on animal life in the depths of the sea.
