 227, 228 (VII). pyrostoma of Eeeve (Conch. Syst.), as of Sowerby's Species Conchyliorum. 



The plates of Cyclostoma (together with those of Melo, Pandora, and Amphidesma) were 

 originally intended to appear in the 'Species Conchyliorum' of the late G. B. Sowerby. He 

 did not, however, publish them, but discontinued his beautiful, yet unremunerative. work, after 

 the first number. Subsequently to his decease, a few imperfect sets were 'sold by one of the 

 principal London dealers in second-hand books, and issued as " Species Conchyliorum, 

 part ii." 



The first five plates of Melania, those of Ostrea, and those of Ampullaria, were conjointly 

 published, in three parts, on the twenty-fourth of November, 1854; the 'Miscellany' was not 

 then continued until the first of October, 1857. Owing to the unfortunate destruction of the 

 lithographic stones, and the too delicate style of engraving adopted in certain of the copper- 

 plates, a very limited number of perfect sets can be supplied to the public.
