collected about thirteen to fourteen miles north-east of Buckie, in 50 to 55 
fathoms, November 3rd, 1900. Jdya cluthe is quite distinct from any other 
species of Jdya. The difference in the armature of the first thoracic 
feet and of the form of the fifth pair is marked, and are of themselves 
sufficient_for distinguishing the species. 
Idya minor, T, and A. Scott. 
A few specimens of this Zdya were obtained in a gathering of Copepods 
collected in the store-pond of the Sea-Fish Hatchery at Bay of Nigg, in 
August, 1900. They occurred amongst crowds of Idya Surcata, and were 
readily distinguished by their small size, The same species was obtained 
in a cathering collected by hand-net in the Bay of Nigg on October Ist. 
Idya longicornis, T, and A. Scott. 
This species was obtained in Lerwick Harbour, Shetland, in the same 
gathering with Alieutha purpurocincta already referred to. The occur- 
rence of Jdya longicornis here extends the distribution of the species 
considerably.

This species occurred in some dredged material collected near the head 
of Loch Hil (off Loch Linnhe), in 10 to 15 fathoms, April 3rd, 1900. 
S. luteus was added to the British fauna in 1893 as a new species under 
the name of Remigulus tridens, from specimens collected near the mouth 
of Loch Spelve, Island of Mull, in 1892 (but not recorded till the 
following year). As the species, however, had already been described by 
Canu and Cuénot, as indicated above, the name Remigulus tridens 
necessarily becomes a synonym. So far as I know, Synatiphilus luteus 
‘has not been obtained anywhere else in Scotland than in the district of 
Loch Linnhe. It seems to be a rare species. 
CoRYC#ID. 
Coryceus anglicus, Lubbock. (Pl. XVIII, fig. 11.) 
In my paper on tow-net gatherings published in the Highteenth Annual 
Report, Part IIIT., I recorded Coryceeus anglicus from the Firth of Clyde, 
and submitted a description of the species, which was illustrated by a 
number of figures ; these figures were prepared from a female specimen, 
as no males had been observed. One of the gatherings which were 
collected during the investigations carried out on board the steam trawler 
“St. Andrew” was obtained while the vessel was proceeding along the soutn- 
east coast of Shetland between Lerwick and Sumburgh Head, and about 
seven miles off shore; the gathering was collected by passing the water from 
the donkey-pump through a fine tow-net. In this gathering, collected on 
- October 16th, three specimens of a Coryceus were found, which I at 
first thought ‘might be C. obtusus, Dana, as the genital segment of the 
abdomen possessed a small but distinct ventral hook at its proximal end,
