thrush, but very greatly more powerful. Whatever be the 
habit of the bird in England, I am certain it seldom favours 
us with its song in Scotland, and upon that subject I should 
be obliged if you could give any information. The song- 
thrush sings occasionally in winter, but we are not accus- 
tomed to hear birds singing in tlie midst of snow-storms. 
VI On Spines a} id Plates of a Sjmapta (Chiradota of Esch.), from the 
Stomach of a Flat-fish, taken off the East Coast of Scotlartd. By 
Charles W. Peach, Esq. 
Although several specimens of Synapta have been taken 
on the west coast of Scotland, I can find no notice of their 
occurrence on the east side. Having found the plates and 
spines of one in the stomach of aflat-fish from the east coast, 
I have thought it right to lay the discovery before the 
Society, in the hope of inducing others to look out for living 
specimens from that part. 
The spines now exhibited are those of Synapta inhcerens 
of Mliller. I refrain from farther particulars about them, 
beyond saying that, although the specimens were few, I 
found anchors attached to plates, as well as loose plates and 
detached anchors. They agreed with those figured in the 
paper of Woodward and Barrett, which will be mentioned 
in the list which follows. As the history of these curious 
animals is scattered through various publications, I hope it 
will not be unacceptable to those who take an interest in 
the subject, and useful to them as a reference to British 
species.

1. Synapta digitata, Montagu. First found by Montagu 
in South Devon. Mr Joshua Alder got it in abundance, in 
1844, in Eothesay Bay ; and in 1845, in Torbay, Devon- 
shire. Mr Bailie dredged it in Biterbury Bay, and at the 
Arran Isles, on the west coast of Ireland. The Eev. Charles 
Kingsley got it, in January 1854, near Torquay. Mr W. P. 
Cocks found it, in blue mud and sand, at Helford, also at
