4 Descriptions of New Species of Marginella, 8fc. 



amygdala Kiener, and the latter having been given to a worn 

 example of a peculiar aspect, which is now ascertained to be- 

 long to a variety of M. quinqueplicata Lam. M. Petit, in his 

 "Journal de Conchy liologie " for Nov. 1851, describes and 

 figures a Marginella Hainesii, which is apparently identical 

 with the shell I had called M. vermiculata, and does not ap- 

 pear to me to possess sufficient distinctive characters to war- 

 rant its separation from M. quinqueplicata. Should it prove 

 otherwise, the name of M. Hainesii must be adopted. 



In the same journal (which should be more widely known 

 and circulated among conchologists than it is), May, 1851, 

 M. Petit has published a well-digested catalogue of recent and 

 fossil Marginellce. Including Erato and excluding a few 

 species which M. Petit thinks should be retained for the genus 

 Volvaria, he enumerates 155 recent and 27 fossil species. 

 "We note here, that M. pudica Gaskoin, which appears in the 

 catalogue as a distinct species, should have been placed as a 

 synonym to our M. chrysomelina. We are in doubt as to M. 

 Delessertiana Recluz, not having seen the description in Re- 

 vue Zool, 1841. but from the fact that M. Petit doubtfully 

 quotes for this species fig. 141 of Sowerby's Thesaurus, we 

 are inclined to regard it as identical with Orbigny's M. alboli- 

 neata, which does not appear in M. Petit's catalogue, and which 

 Sowerby's fig. 141 certainly represents. If identical, Recluz' 

 name has probably precedence, though the current French 

 mode of publishing works of the character of the " Mollusques 

 de Cuba" in fasciculi, without date, renders it difficult to de- 

 cide this point. M- ovuliformis Orb. seems also have been 

 overlooked by M. Petit. 



In an article aiming to show the distinctive character of 

 Cyprcea histrio, and C. reticulata, published in vol. 4 of An- 

 nals of Lye. Nat. Hist., pp. 447, 448, I mentioned that I had 

 not had opportunity to consult Meuschen's Museum Greversia-
