species, it appears to have an extensive distribution ; it has 
been obtained as far north as Franz Josef Land. It was 
described as a Canthocamptus, but may ultimately have to be 
removed from that genus. 
Laophonte littorale, T. Scott, and L. intermedia, T. Scott.— 
These two species are also additions to the Fauna of the Clyde. 
They have only been described within recent years, but both 
appear to be widely distributed. 
Nannopus palustris, G. A. Brady.—This curious Copepod 
appears to be a true brackish-water form, and this is, so far as I 
know, the first record of it for the Clyde. It seems to bea 
scarce species, though its rarity may be rather apparent than 
real, as the following incident would seem to indicate :—A short 
time ago I had an opportunity of examining some raised-beach 
material from Skye. The material was quite dry, having been 
collected a good while ago. In turning over the material I 
observed some objects that lookéd like Copepods, but they were 
so shrivelled up as to be indistinguishable. A careful treatment 
of them with caustic soda, however, relaxed the shrivelled-up 
skin and appendages, so as to render the discrimination of their 
structural details comparatively easy. I then found that a few 
of these mummified Copepods belonged to the species now 
under consideration, and was enabled in this curious way to 
extend somewhat our knowledge of the distribution of Vannopus 
palustris. There had likely been some marshy ground in the 
vicinity of the raised beach where the material had been 
collected, and, being near the sea, would form a suitable habitat 
for Nannopus, and probably other brackish-water species, and in 
the dry weather it would be a comparatively easy matter for 
the Copepods to become incorporated with the outer layers 
of the raised-beach deposit, and be mixed up in the sample 
collected. 
Platychelipus littoralis, G. 8. Brady.—This is another curious 
Copepod, with strong hooked terminal spines on the first thoracic 
feet which remind one very much of those iron hooks which are 
sometimes used by people who have the misfortune to lose a 
hand. Though found in brackish water, Platychelipus is not such 
a true brackish-water species as the last ; its distribution should 
rather, perhaps, be described as “ estuarine.”
