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

 the author, not of the writer of the Report, who is by no moans 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. (jifiantms has the aspect of the large Ischnochiton 

 Magdalensis ; the Ch. muricatits belongs to the Lophyrus group, which is not 

 known so far north ; and the Cli. setosus has also a S. American aspect. The 

 treatise " De Chitone Gif/anteo Camtschatico atlditamentum ad Zoographiam 

 llosso-Asiaticum, auctore Tilesio," was read March 19, 1S23, and published 

 in 1824. It contains a verj- vahiable and (for that period) remarkable account 

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

 in the modern sense. The names, therefore, had bettor bo dropped. Midden- 

 dorfTs new species were first described in the ' Bulletin de la Classe Physico- 

 Mathematique de I'Academie Imperiale des Sciences de St. Petersbourg,' a 

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

 ing dates.
