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 the midst of snow-storms. 



VI On Spines ah d Plates of a Sjmapta (Ohiradota of Esch.), from the 

 Stomach of a Flat-fish, taken off the East Coast of Scotland. 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 Muller. I refrain from farther particulars about them, 

 beyond saying that, although the specimens were few, I 

 found anchors attached to plates, as w : ell 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. 



First, then, Woodward and Barrett's paper, published in 

 the " Proceedings of the Zoological Society of London,"

1, Synapta digitata, Montagu. First found by Montagu 

 in South Devon. Mr Joshua Alder got it in abundance, in 

 1844, in Kothesay 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 Kev. Charles 

 Kingsley got it, in January 1854, near Torquay. Mr W. P. 

 Cocks found it, in blue mud and sand, at Helford, also at
