44. Middendorff. — The synonymy given in Eep. pp. 214-222 is that of 

 the author, not of the writer of the Report, who is by no means prepared to 

 accept the learned doctor's identification of species. The three Chitons quoted 

 with doubt from Tilesius have not been confirmed, as from Kamtschatka, by 

 any other writer. The Ch. giganteus has the aspect of the large IsehnocMtMi 

 Magdalensis ; the Ch. muricatus belongs to the Lopliyrus group, which is not 

 known so far north ; and the Ch. setosiis has also a S. American aspect. The 

 treatise " De Chitone Giganteo Camtschatico additamentum ad Zoographiam 

 llosso-Asiaticum, auctore Tilesio," was read March 19, 1823, and published 

 in 1824. It contains a very valuable and (for that period) remarkable account 

 of the anatomy of Chitons, but it does not profess to name and describe species 

 in the modern sense. The names, therefore, had better be dropped. Midden- 

 dorff's new species were first described in the ' Bulletin de la Classe Physieo- 

 Mathematique de i'Academie Iraperiale des Sciences de St. Petersbourg,' a 

 work of which few complete copies are known in England, under the fblluw- 

 ,ing dates.
