The work by the Rev. T. R. R. Stebbing, F.R.S., entitled 

 A History of Crustacea, has been very helpful to me in the 

 general systematic arrangement of the species, and especially 

 of the Malacostraca. 



My son, Mr Andrew Scott, A.L.S., has given me valuable 

 assistance with the identification of the Entomostracan 

 species ; and I also arn greatly indebted to my friend 

 Mr F. G. Pearcey, for rich collections of micro- Crustacea 

 from the Forth estuary and elsewhere. 



The Map which accompanies this part of the Catalogue 

 shows approximately the limits of the basin of the river 

 and its estuary. It also shows approximately the positions 

 of the ten Experimental Stations laid down by the Fishery 

 Board tor Scotland in the Firth of Forth, since many of the 

 species recorded here were obtained at one or other of these 

 " Stations." The Stations are marked in Roman numerals : 

 Stn. I., Stn. IV., etc. 



In arranging the species, I have followed the classification 

 in Stebbing's Natural History of Crustacea (page 49), in 

 which the Podophthalma have the first place, while the 

 Cirripedia come last. 



The following is the order in which the species in this 

 part (Part 1.) of the Catalogue are arranged.
