Suborder Sympoda.^ 



In the preparation of this part of the Catalogue, I have 

 adhered more or less closely to the arrangement and nomen- 

 clature of Sars Crustacea of Noriuay, vol. iii., published 1899- 

 1900. See also a paper by myself in the Annals of Scottish 

 Natural History for October 1900. 



1 See remarks on this group by Rev. T. R. R. Stabbing, in his account 

 of the Crustacea brought by Dr Welley from the South Seas, published by 

 the Cambridge University Press, December 1900.
