NOTES ON SCOTTISH CUMACEANS 217 



Fam. I. 

 Gen. CUM A, M. Edwards, 1828. 



(1) CUMA SCORPIOIDES (Monf.}. Firth of Forth (recorded by 

 Goodsir under the name of Bodotria arenosa). Firth of Clyde 

 " taken in surface-net after sunset ; depth 4-5 fathoms, Blackwater- 

 foot, Arran " (Robertson). I have not myself observed this species 

 in any gatherings of Scottish Crustacea. In it the inner rarnus of 

 the uropods is composed of a single piece. The form described 

 and figured by Goodsir as Bodotria arenosa is evidently a male, as 

 the abdominal segments are provided with what appear to be fully 

 developed pleopods. 



(2) CUMA EDWARDSII, Goodsir. Firth of Forth (Goodsir ; Leslie 

 and Herdman). This species, which has the inner as well as the 

 outer uropods two-jointed, appears to be generally distributed along 

 the east coast of Scotland. I have records of its occurrence in 

 the Firth of Forth, off Aberdeen, and in the Dornoch Firth. I 

 have, however, no record from the west coast. 



(3) CUMA PULCHELLA, G. O. Sars. Appears to have a wide 

 distribution, but being a small species, is easily overlooked. It was 

 observed for the first time in Scotland in the Firth of Forth, where 

 it was obtained in 1889-90. For several years this was the only 

 Scottish locality in which it was known to occur ; recently, however, 

 I have been enabled to record its occurrence in the Clyde, having 

 obtained one or two specimens in a gathering of Crustacea collected 

 in the vicinity of the island of Sanda. 1 



Gen. IPHINOE, Spence Bate, 1856. 



(4) IPHINOE TRISPINOSA (Goodsir). Firth of Forth (Goodsir). 

 Firth of Clyde taken plentifully in Kames Bay, Millport (a little 

 beyond low water, and in the surface - net), and Loch Ranza 

 (Robertson). I have taken it in the Firth of Forth, where at times 

 it is moderately frequent, especially in bottom tow-net gatherings ; 

 and also occasionally in Loch Fyne, and in Kilbrennan Sound. 

 Iphinoe ( Venilid) grad/is, Spence Bate, is the male of this 

 species. 



(5) IPHINOE SERRATA, Norman. I obtained this species in 

 moderately deep water in Port Bannatyne Bay, Firth of Clyde, in 

 March 1887. Also in a tow -net gathering, from 40 fathoms, 

 collected in the Moray Firth in June 1898; and in a gathering 

 made off Ballantrae, Firth of Clyde, in July 1899. I have not 

 observed this Iphinoe in the Firth of Forth.
