2i6 ANNALS OF SCOTTISH NATURAL HISTORY 



in the fauna of Norway, which in these volumes is being so 

 fully described and figured. 



With the assistance of the published parts of volume iii., 

 I have been enabled to prepare the following notes on 

 Scottish Cumacea, which may not be without interest to 

 those who are devoting some attention to these curious 

 animals. In these notes I have generally adopted the 

 names and the arrangement of the species employed by 

 Professor Sars, while among other books and papers which 

 have been consulted are the following, viz. : Middlehavet's 

 " Invertebrate Fauna," part ii. ; " Cumacea," by Professor 

 G. O. Sars ; ' Notice of Thirteen Cumacea from the Firth of 

 Clyde,' by the late Dr. Robertson of Millport (published in 

 part i. vol. iii. (N.S.) of the " Proceedings and Transactions 

 of the Natural History Society of Glasgow," 1889); "A 

 History of Crustacea," by the Rev. T. R. R. Stebbing, 

 F.R.S. ; 'On a Crangon, some Schizopoda and Cumacea 

 new to or rare in the British Seas,' by the Rev. Canon 

 A. M. Norman, M.A., etc. (published in the " Fourth Annual 

 Report of the Fishery Board for Scotland," 1886); and 

 various papers on Crustacea by the present writer, published 

 in the Annual Reports of the Fishery Board for Scotland, 

 in the " Annals of Scottish Natural History," and elsewhere. 



In a paper on the fauna of Loch Fyne, by the late 

 George Brook and myself, published in the " Fourth Annual 

 Report of the Fishery Board for Scotland" (1886), Heini- 

 lamprops uniplicata is recorded, but somewhat doubtfully, 

 amongst a few Cumaceans observed in East Loch Tarbert. 

 The specimens supposed to belong to Hemilamprops unipli- 

 cata were immature, and as no adult specimens, which could 

 satisfactorily be ascribed to this species, have yet been 

 observed in the Clyde or anywhere else around the Scottish 

 coasts, I have excluded it from the present list. 



Professor Sars divides the Cumacea into nine families, 

 eight of which are represented here, viz. the CUMID^, 

 VAUNTHOMPSONIID^E, LAMPROPID^E, LEUCONID.E, DIASTY- 



PSEUDOCUMID/E, NANNASTACID^E, and CAMPY- 

 The PLATYASPID/E the third family in Pro- 

 fessor Sars' arrangement is not represented in the Scottish 

 cumacean fauna.
