established one. I Iiowover quite agree with Mr. Gray in con- 

 sidering 7'. carneus a Trochus^ as that genus is now considered ; 

 on account solely of its operculum : it was merely, I repeat, re- 

 ferred to Turbo of Lamarck ;;ror/s/oH«%, in conformity with his 

 arrangement ; and with a view not to add to the synonyms of 

 Turbo Margarita of Mont, by a change of its genus.* 



I take the present occasion to notice some more important 

 errors in the synonyms of the Chitones. C. cinereus, Zoo]. Jouni. 

 vol. ii. p, 99. is undoubtedly C. marginatus of Montagu, Turton, 

 and most British authors ; though there is no reason still to doubt 

 its being tlie true C. cinereus of Linna?us, Born, aijd the older 

 writers; to whom I am well pleased to add the name and authority 

 of Poli. C. Jsellus Zool. Journ. ii. p. 101, on the other hand, 

 proves to be the C cinereus of Montagu, Turton, aud some others; 

 but cannot be identified with C. cinereus of the three above 

 named authors. 



By ihe kindness of Mr. Children, I have been able clearly to 

 identify C. aselloidesy Zool. Journ. ii. p. 103, with C albus of 

 Montagu : how far the synonyms of other authors may be brought 

 together for C. albus^ it is very difficult to say. I have frequently 

 seen small specimens of C. Jsellus of Zool. Journ. in collections, 

 under this name, which has probably been given, indiscriminately, 

 to small paler coloured and white specimens of both the species. 

 A card in the British Museum, marked " C. albus ^ Mus. M." 

 amongst the remains of Montagu's Collection, sufficiently autho- 

 rises his synonym. For the rest, the synonyms of Linn., Grael., 

 and Turton appear safe. 



In the present state of things, it will be most advisable to 

 retain the names of former British writers, for these three species. 

 It is very desirable, at any rate, to get rid of the barbarous one, 

 aselloides. At some future opportunity I shall endeavour fully 

 io clear up the whole of the synonyms, particularly those of 

 Chemnitz. R. T. L. 



• Tlie aperture is represented too angular in the fij^ure in the Zool. Journ. ; 

 particularly in the magnified fig. 136., at its lower part. The aperture is very 

 slightly, if at all angular at the top, though the lips are disunited ; and almost 

 imperceptibly at the lower part, though a little more so in one specimen only, 

 aud that the distorted? one mentioned.
