INTRODUCTION. 
Four species of Bryozoa, Lyropora (?) erkosoides Etheridge, Fenestella 
affluensa Bretnall, Fenestella horologia Bretnall, and Aetomocladia amhrosoides 
Bretnall, are hei’o revised from the type material in the Western Australian 
Geological Survey Collection. In the original descriptions of these species 
the number of the holotype of eacli species is quoted, but in labelling the 
specimens the same number was used for all the specimens referred to the 
species, and in some cases the original labels are now missing ; lectotypes 
are therefore chosen from the syntypes of the species revised, and the speci- 
mens liave been recatalogued.
