Falmouth. It appears to range to the Mediterranean, and 

 has been found in several other foreign stations. 



2. Synapta inhcerens, 0. F. Miiller. First found at Chris- 

 tiansand, Norway, and described in the " Zoologica Danica ," 

 1781. Mr Henslow first got it at Aberystwith and Cric- 

 cieth, in North Wales, and communicated it to Dr Leach 

 in 1819, who named it Jemania Henslowanii. It was also 

 got in the latter locality, by Mr J. W. Wilton, in 1856. In 

 February 1856, Mr E. C. Buckland got it in Lihon Bay, 

 Guernsey. " A microscopic preparation of the skin of this 

 specimen shows 150 anchors in the field of the one-inch 

 object-glass/' Mr Cocks got at Falmouth. Mr M £ Andrew 

 in Bantry Bay, in August 1857. So far for the above 

 paper. 



3. Synapta Gallieni vel Sarniensis. At the meeting of 

 the British Association in Bath, in 1864, Dr Herapath 

 described a species got in Bellegrave Bay, Guernsey, by M. 

 Galliene, and has fully described and figured it in the 

 " Quarterly Journal of the Microscopical Society" for 1865, 

 new series. This has also been taken by Dr M'Intosh at 

 North Uist, in the Hebrides. 



4. Dr Herapath mentions, in his paper, one taken by Pro- 

 fessor Wyville Thomson in Ireland, and wishes it to be 

 named Synapta TJiomsonii. 



5. Synapta BusJcei, M'Intosh. Found by Dr M'Intosh in 

 Lochmaddy, North Uist, Outer Hebrides, and described by 

 him in the "Proceedings of the Eoyal Society of Edinburgh," 

 vol. v. (1862-65), p. 612, fig. 6. 



Thus, then, although many others have been found in 

 other parts of the world, at present only five species have 

 been found on the British coasts ; and although few, their 

 spines, &c., make such beautiful microscopic objects, they 

 are well worth searching for. 



I must here express my best thanks to Dr Wm. Carpenter, 

 for the use of Woodward and Barrett's paper, and to Dr J. 

 A. Smith, for the " Proceedings of the Eo} r al Society of 

 Edinburgh." For Dr Herapath's paper I am indebted 

 to the University Library authorities.
