Thompson — Fauna and Flora of Valencia Harbour^ Ireland. 741 



Atlantic traverse, between Ptockall and North coast of Ireland... 

 I have on several occasions found it on the west coast of Scot- 

 land, and Scott reports it from the Forth. The " Challenger" 

 took it about Australia, the Philippine Islands, and between 

 Ascension and the Azores. I found it common about the 

 Canary Islands. It and the other members of the genus Can- 

 dace are at once distinguished by the dark-coloured antennae, 

 spines, and plumes, and terminal spines of the swimming feet. 



Anomaloeera patersonii. This very conspicuous and beautifully 

 coloured species was found on only three occasions throughout 

 the foul' years. It is very variable in its distribution, often 

 occiuTing in immense profusion, but it is otherwise uncommon. 

 On more than one occasion I have seen the surface of the sea, 

 for many miles around the Isle of Man so densely covered 

 with this animal as to make it distinctly recognizable from the 

 ship's side. 



Parapontella brevicornis, hitherto reported only from the English 

 Channel, around the British Isles, and as far north as the 

 Shetland Isles, occurs sparingly thi'oughout the collection. A 

 shoal of it, however, was taken in JSTovember, 1896, although 

 none were found for a considerable period before or after. 



Acartia clausii was very common through the collection. 



Acartia discaudata was only once noticed ; it, very possibly, may 

 have escaped detection on some other occasions. 



CxCLOPIDiE. 



Oitlionia similis was, as might be expected, common throughout the 



collection. 

 Cyclopina littoralis, a common pool species, was only once taken. 



Haepacticid^. 



Ectinosoma atlanticum is a very minute, open sea lover, and was 

 probably much more common than recorded, having escaped 

 through the tow -net meshes. 



Alteutha purpurea, one specimen of which was sent to me from 

 Valencia, taken in December, 1898, is a most important find, 

 the only previously known British habitat, I believe, being 

 Tarbert Loch, Clyde, as recorded by Scott and Brady, and 

 where I have occasionally also found it. Its deep reddish 

 pm'ple colour conspicuously distinguishes it.
