Review of Prof. C. B. Adams's 'Catalogue of the Shells 

 OF Panama'*, from the Type Specimens. 13y Philip P. 

 Carpenter, B.A., Ph.D.

 Cuming, and through his kindness were freely used in prej)aring 

 the Mazatlan Catalogue, thus avoiding the necessity of manj' syno- 

 nyms. An instructive lesson in candour and forbearance may be 

 learnt by comparing together the works of any two naturalists of

 as he sees them. If this be true of such full and precise diagnoses 

 as those of Adams and Gould, how much greater must be the difii-
