224 ANNALS OF SCOTTISH NATURAL HISTORY 



1893, along with several other interesting Crustaceans; 1 and after- 

 wards in various parts of the Clyde area, as near Lowburn (Upper 

 Loch Fyne 2 ), at Tarbert Bank (Lower Loch Fyne) in moderately 

 deep water (40 fathoms), between Arran and the Coast of Ayrshire, 3 

 off Ballantrae in 15-20 fathoms, and near the mouth of the 

 Clyde estuary in 64 fathoms. This and the next species have 

 usually been captured on a muddy bottom in moderately deep 

 water, and never in shallow sandy bays. In this species the cephalic 

 shield is smooth, and the colour of the whole animal when alive is 

 bright reddish or purplish, which to the unaided eye appears to be 

 uniform, but under the microscope it breaks up into numerous 

 minute points of colour on a lighter background. 



(32) Campylaspis costata, G. O. Sars. — This appears to be a 

 rarer species than the last. It was first observed in some material 

 dredged at the mouth of Port Bannatyne Bay, Bute, in November 

 1866, and, as far as I know, the only other places where it has 

 been obtained are : (1) Tarbert Bank, Loch Fyne, in 17-20 fathoms, 

 amongst some material dredged in December 1899 and March 

 1900, and kindly forwarded to me by Mr. F. G. Pearcey of the 

 Fishery steamer "Garland" ; and (2) in Loch Aber (north-east end of 

 Loch Linnhe), in material dredged in 82 fathoms by the "Garland,"' 

 and sent to me for examination. The specimens were of a reddish 

 colour. 



Thirty-two species of Cumacea are recorded in these 

 notes, but this number would probably be considerably in- 

 creased if a more thorough investigation were made of the 

 Crustacea around our shores. Many of the Cumaceans are 

 very small and easily overlooked ; and the characters which 

 distinguish the different species are correspondingly minute 

 and not easily detected. A careful examination is therefore 

 desirable, even of forms that have a close superficial re- 

 semblance to each other, in order to avoid mistaking the 

 one species for the other.
