Annals and Mag. of Nat. Hist. — Mr. Cockerell's paper on the Slugs 

 in the British Museum, deals with the Pirainea section of Amalia, 

 which unlike the Tainionia section, are widely distributed in 

 temperate regions. The various forms of A. gagates a.xt described, 

 and descriptions given of a number of new forms. This paper forms 

 the fourth of the series, which constitute a most valuable adilition to 

 our knowledge of this class of the Mollusca. 



Mr. R. B. Newton proposes that the term" Cyclostonia should be 

 abandoned, and that oi Pomatias used instead. The term Cyclostonia 

 was first used by Lamarck, (1779), for a group of shells that we now 

 term Scalaria. It was next used by Lamarck, (1801), for what he 

 subsequently termed Delphinula, (1803). For the genus Scalaria, 

 Mr. Newton proposes to drop the term Cyclostonia, and write 

 Delphinula. The Cyclostonia of modern authors, was originally 

 termed Pomatias by Studer. (1789), of which our C. elegans was the 

 type. Mr. Newton therefore proposes, that Pomatias be adopted, 

 instead of Cyclostonia. The Pomatias of Hartmann, is then said to 

 be without a name, so is termed Hartmanuia, Newton. 



Canon Norman thinks Mr. Newton has misapprehended the facts 

 of the case. Lamarck, says Canon Norman, did not form three 

 genera named Cyclostonia, but one, but applied tlie name with 

 different applications, viz. , it included all the genera named in Mr. 

 Newton's article. The argument is specially based upon Rule 10, 

 of the British Association Rules of Zoological Nomenclature, " A 

 name should be changed, which has before been proposed for some 

 other genus in Zoology or Botany, or for some other species in the 

 same genus, when still retained for such genus or species. " 



Mr. Newton's reply, materially strengthens his position. lie claims 

 priority for Studer, which cannot be overlooked on the ground of the 

 Ihitish Association's rule, which in Mr. Newton's opinion, requires 

 revision. 



Mr. Cockerell, (Brit. Nat. Mag.), points out that Cardiotoma of 

 Sandberger, ought to be used for the Pomatias, Auctt. instead of 

 Hartmannia, this latter term having already been twice used as a 

 generic title in Botany. 



Mr. Newton gives the corrected synonymy, as follows : — 

 Genus Pomatias, B. Studer, 1789. 



Type = A^r/i'« elegans, Miiller, 



(Non. Hartmann, iS2\ = Hartmanuia). 



= Cyclostomiis, Montfort, 1810. 



= Cyclostonia, B. Studer, 1820. 

 Genus Delphinula, Lamarck, 1803. 



Type= Tnrbo delphinus, Linnreus. 



= Cyclostonia, Lamarck, 1801. 



{Nou. Lamarck, 1799). 

 Genus Hartmannia, R. B. Newton, nom. mat. 



Type= Cyclostonia patuliim, Draparnaud. 



= Pomatias, Hartmann, 1 821. 



(Non. B. Studer, 1789). 

 Genus Scala (Klein, 1753), G. Humphrey, 1797. 



Type= Turbo Scalaris, Linnaeus. 



= Cyclostonia, Lamarck, 1799. 



= Scalaria, Lamarck, 1801. 

 A most interesting abstract of Dr. Plate's paper, from the " Zool. 

 Auz.," February 1891, is given, in which he describes a rudimentary 

 heart, of a very simple structure.
