12 BEITISH TUXICATA. 



two, Glavelina lepadiformis and Sidnifum 

 were described by Savigny in his ' Animaux sans 

 Vertebres ' (1816) from specimens sent to him from the 

 English coast by Dr. Leach; and one, tin! pa moiiili- 

 t'oniiis, was described by Dr. Macculloch in his 

 'Western Isles of Scotland' (1819). Fleming omits 

 Gartner's Ascu.lia, mamillaris and Turton's Alcyonmm 

 Btniasii. 



In the ' Edinburgh Philosophical Journal ' for 1830 

 Dr. Coldstream recorded four species from Scotland, 

 describing two, Synoicum riibririu from Lamlash Bay, 

 Arran, and A^ciilin m<jox from East Loch, Tarbet, as 

 new. The others are SiJuyu-in. tnrl>ln<itinn and As<'i<lli 

 I'trniium, neither being a new British record.] 



Dr. Lister described two new species in the ' Philo- 

 sophical Transactions ' for 1834. One of these was, 

 in the following year, named r<'>-<>i>lir<i Lister i by 

 Weigmann ; the other, which was merely designated 

 Polyclinum by its discoverer, was afterwards named 

 Leptodinum Listerianum by Milne-Edwards, 



[In the same year (before the publication of Lister's 

 paper) George Johnston (' Mag. Nat. Hist.,' vii) de- 

 scribed two new species of Aplidium from the Berwick 

 coast, A. fiJlax and A. imfin/s ; and Robert Templeton, 

 under the initials " C. M." (luc. rit.), described and 

 figured as new British species Ax<-'nl] '? t/ni/i/m and 

 A. ': anceps, the latter from Belfast Lough.* In 1839 

 Sir John Dalyell (' Edin. new Philos. Journ., xxvi) 

 described the development through the tadpole state 

 (termed " spinula " l)y him) of a simple and a compound 

 Tunicate from the coast of Scotland which he named 

 respectively A.^-iilln ^ipilla and Aplblinnt cen-ticoxintt. 

 In the ' Report of the British Association ' for the same 

 year Forbes and Goodsir recorded Awlilin intestinalis 

 from the Orkney and Shetland Islands, naming as new 

 species, but not describing, A. rcltiitntu, A.-ruyosn (both 

 pre-occupied names), and A. rnltrnx ; and in the 'Report' 



: The locality for Ascidia gemina is not given, but in 1840 William 

 Thompson ('Ann. Nat. Hist.,' v) recorded it from Strangford Lovigh.
