NOTES ON SCOTTISH CUMACEANS 223 



Moray Firth in 1893, and about 6 to 7 miles east by south of 

 Girdleness, in 50 fathoms, in May 1898. In this last gathering 

 Petalosarsia was moderately frequent, and both males and females 

 were obtained. This Cumacean was described in the earlier 

 Scottish records under the name of Petalomera declivis, but Petalo- 

 mera was found to be preoccupied, and Rev. Mr. Stebbing proposed 

 Petalosarsia as a substitute. 



Fam. VIII. NANNASTACIDiE. 

 Gen. Nannastacus, Spence Bate, 1865. 



(29) Nannastacus unguiculata, Spence Bate. — The only 

 records of this species are for the Clyde ; I have not yet observed 

 it on the east coast of Scotland, nor do I know of any record of it 

 from the east side. The late Dr. Robertson describes it as 

 " moderately common " about Cumbrae, and the investigations 

 carried on by the Fishery Board for Scotland have shown it to 

 be present in Loch Fyne, in Kilbrennan Sound, and other parts 

 of the Clyde estuary. 



Gen. Cumella, G. O. Sars, 1865. 



(30) Cumella pygm^a, G. O. Sars. — This diminutive species 

 has apparently a wide distribution around our coasts. The late Dr. 

 Robertson records having "taken it plentifully" at low water, 

 Cumbrae. I have notes of its occurrence at Tarbert, Loch Fyne, in 

 Kilbrennan Sound, and other places in the Firth of Clyde. It was 

 obtained in the Moray Firth in November 1897 ; in the Firth of 

 Forth in 1890, but only recently identified; and in a gathering of 

 Crustacea, etc., collected by Mr. H. C. Williamson, in Aberdeen Bay, 

 on the 9th of August last (1900). 



Fam. IX. CAMPYLASPIDvE. 

 Gen. Campylaspis, G. O. Sars, 1864. 



(31) Campylaspis rubicunda (Lilljeborg). — This species, which 

 forms the type of an interesting group of Cumaceans, was first 

 noticed in the Firth of Forth, in the vicinity of the Bass Rock, in 

 1889, and was recorded doubtfully as Campylaspis affinis, G. O. 

 Sars. 1 Since that time this species has been observed in various 

 other parts of Scotland. It was obtained in the Moray Firth in 



1 "Eighth Annual Report of the Fishery Board for Scotland," part hi. 

 p. 330 (1890).
