 Forekommencle Mysider., Frste Hefte, p. 24, tab. i. (1870). 

 Habitat. — Frequent all over the Forth, from Inchkeith to May Island, 

 as well as outside of the South Bay. How it happens that this species 

 has escaped observation hitherto may not be easily explained. Erythrops 

 pygmcea and serrata have recently been observed by me in considerable 

 numbers in the Moray Firth. E. pygmaa was added to the British fauna 

 in 1886, when specimens were taken by me in E. Loch Tarbert, Loch 

 Fyne, while carrying on the Board's work at that place ; the other has 

 been taken at the Shetland Islands, by the Bev. A. M. Norman, and is 

 described in his last Dredging Beport (1868). All the species of Erythrops 

 are small, but are readily recognised when living by their bright red 

 eyes; when they are kept a while in spirit^ however, the eyes turn 

 white. E. goesii is an addition to the British fauna.

 Habitat. — Two specimens were observed in some bottom tow-net 

 material, collected near Fidra, and one was taken near Inchkeith, 

 November 1888. Though this species seems to be somewhat rare in 

 the Firth of Forth, it was of frequent occurrence among bottom tow- 

 net material collected in the Moray Firth. Dr Henderson records two
