Dr. Jay, and part to Mr. Stainforth. The specimens in Mus. Cum. were re- 

 ceived from Dr. Jay ; those in Mus. Hauley from Mr. Stainforth. In the 

 third edition of Dr. Jay's Catalogue, 1839, appear the following species which 

 have not been identified, and localities not confirmed.

54. C B. Adams. — After arranging the duplicate Eeigen Collection in the 

 State Museum at Albany, New York, I proceeded to Amherst, Mass., to 

 study the type-collection from which Prof. Adams's book was vmtten. The 

 result is embodied in a " Review of Prof. C. B. Adams's ' Catalogue of the 

 Shells of Panama,' from the Type Specimens," written for the Zool. Soc. in 

 Jan., and published in the Proceedings for July 1863, pp. 339-369. In this 

 paper the synonymy between the Mazatlan and Panama Catalogues is pointed 

 out, and the species assigned to the modern genera. The following are the 

 principal corrections needed in the list, Eep. pp. 267-280. The results in 

 the succeeding paragraphs, pp. 280, 281, should be altered accordingly.

3. Ovula neglecta=avena, var. 



8. Cyprcea punctulata ; quite distinct from C. arabicula, 

 11. Cypraa rubescens, C. B. Ad., = T. sangtiinea, dead. 



15. Marginella sapotilla, 0. B. Ad., is perhaps a large form of sapotiUa, Hds. It 

 is destitute of the sharp posterior labral angle seen in the West Indian 

 specimens of ceertdescens. 

 33. Ohva araneosa, 0. B. Ad.,= 0. Mekhersi, M. 591. 

 35. Oliva pellitdda, C. B. Ad., = O. aureocincta, M. 598, dead. 

 40. Oliva oenulata, C. B. Ad., = O. angulata, jun. 

 43. Nassa caneseens=iea,6i sp. of N. pagodus. 



50. Nassa pagodus, C. B. Aa..,=deciissata, Kien. [ ? non. Lam.J = acMto, M. 625. 



51. Nassa Panamensis has the operculum of Phos and Norihia, = exilis, Pws. 



52. Nassa proxima+Si N. striata, C. B. Ad. [non Mus. Cum. = N.paupera, Gld.], 



+N. crebristriafa, M. 633, are probably vars. of JV. versicolor. 



53. Nassa scabriuscula, C. B. Ad., + 56 N, Wilsoni=N. complanata, Pws. 

 70. P«?7)Mro/oueofofe, probably=worn sp. of Ctima costata, M. 610. 



74. Purpura osculans+Rh. Californicus +Rh. disians, are probably vars. of RMzo- 



cheilus mix. 

 81. Columbella costellata, C. B. Ai.,=Anackis scalarina, Sby. 

 98. Columbella parva, C. B. Ad., = dead sp. of Anacliis pygmcea. 

 103. Columbella tessellata, C. B. Ad. (non Gask.), = ^. Guatemalensis, Rve. 

 110. Cassis abhreviata can scarcely be distinguished, in some of its many varieties 



from the Texan Bezoardica inflata. 

 15-1. Cancellaria affinis scarcely differs from C. urceolata, M. 445.
