 all previous writers.

Neither of these figures aj^pears to give a good idea of the 

 same shell as represented by the author at pi. 45. f. 1 3 ; particu- 

 larly that of Gualtieri, which might as well pass for any other 

 species. 



Utiio litoralis^ et batava, two common species frequent 

 in most parts of the continent, complete the number of this 

 genus; but neither of these is found in Great Britain. 



Having now given our readers a short abstract of the con- 

 tents of this valuable addition to zoological science, we re- 

 commend it to their further attention ; a few copies have been 

 imported by Mr. Wood, 428, Strand. W. B.

Three plates only are given in this number, occasioned, we 

 presume, by the additional letter-press composing the different 

 indexes and title-pages of the second volume, which this num- 

 ber completes. ^ These plates are however more rich in figures 

 than usual. The first contains two birds, which we have been 

 accustomed to consider as totally distinct ; the Sylvia cayana, 

 and the Sylvia cyanocephala of most writers. But Mr. Swain- 

 son appears to have ascertained that they are male and fe- 

 male of the same identical species, and has referred them to 

 their proper station in the system, under the name of Necta- 

 rini a cyanocephala. PI. 118: Conus generalis ; a well-known 

 shell, but enriched by five figures of the different varieties, not 

 well represented by authors. 



Ampullaria globosa .- a species tlius defined : — A. testa glo- 

 bosa, lajyissima, olivacea; spira depressa; aperturaj margine 

 crasso, fulvo, sulcato ; umbilico parvo, contracto, juxta basin 

 posito; ojjerculo testaceo. 



Tlie observations on the Ampidlarice are here concluded ; 

 and Mr. S. has satisfactorily shown, that the characters given 

 to this genus by Lamarck, are perfectly correct. 



We should like to see a larger portion of diis valuable work 

 devoted to Entomology : this miglit be done by curtailing the 

 Shells in this publication, and bringing them in some other 

 work exclusively on conchology.
