Here, curiously enough, the wide-spread forms preponderate 
oyer the others more than was the case in the previous list ; but 
it is noteworthy that the percentage of southern forms has 
diminished, which emphasizes still more strongly the Arctic aud 
Scandinavian affinities of the Clyde deep-water fauna. These 
results illustrate in a very interesting manner several of the 
generalizations of the late Edward Forbes. 
In conclusion, I may be allowed to express the hope that the 
facts recorded above may furnish the nucleus of more extended 
series of observations. I hope to continue the work as oppor- 
tunities arise, and I shall be extremely grateful to any naturalists 
who will furnish me with records of the occurrence, with the 
exact locality and depth, of any species in the Clyde sea-area or 
neighbouring seas.
