Bryozoa. — No fresh-water Bryozoa were collected by the Lake 
Survey, no doubt chiefly because there was no one on the staff 
acquainted with the group. Dr Wesenberg-Lund, of Denmark, a 
specialist in the group, did not find any during his visit to Scotland, 
but he examined very few lochs. That Bryozoa exist in the lochs is 
known from the work of Mr Hood, of Dundee. He has collected 
8 species, and 7 of these, enumerated below, were found in lochs 
in Perthshire sounded by the Lake Survey. Mr G. West found stato- 
blasts of a species in a small loch in Fife which was not surveyed.
