series, vol. ii., and which is evidently identical with 

 Koch's Pherusa alba (" Herrich S chaffer, Contin. of 

 Panzer," Fasc., 180, pi. 24). Another curious blind 

 species, closely allied to Platyarthrus, has been described 

 by Schobl, under the name of Typhloniscus Steinii, in the 

 " Proceedings of the Imperial Academy of Vienna for 

 1860." It lives in ants' nests. The memoir is illustrated 

 by ten elaborate plates. 



These animals have recently attracted considerable 

 attention amongst foreign carcinologists, since, in addition 

 to the special memoirs of Brandt ( a Conspectus Mono- 

 graphiae Crustaceorum Oniscodorum," in Bull. Soc. Nat. 

 Moscow, 1833) ; Lereboullet (" Sur les Crustaces de la 

 Famille des Cloportides qui habitent les Environs de 

 Strasbourg," in the " Contes Rendus," 1845, t. 20, No. 6, 

 and in the " Memoirs of the Nat. Hist. Society of Stras-

 memoir, entitled " Analysis of certain allied Genera of 

 Terrestrial Isopoda," in the " Natural History Review," 

 vol. iv., 1857, and supplement in ditto, 1858 and 1859, we 

 have greatly availed ourselves) ; there have been pub-

 overlooked, namely, Burgersdijk's " Specimen Acade- 

 micum inaugurale continens Annotationes de quibusdam 

 Crustaceis indigenis," 8vo, Lugduni Batav. 1852 ; 

 Schnitzler's Memoir " de Oniscineis agri Bonnensis," 

 8vo, Colonize, 1853 ; Stem's " Catalogue of the Crus- 

 tacea and Myriapocla of the Grisons/' published in the 

 " Annual Report of the Natural History Society of the 

 Grisons" for 1855, in which fifteen species of the family 

 are described ; and Johnsson's " Synoptisk Framstallning 

 af Sveriges Oniscider, Upsala," 1858. In Koch's {C Con-
