ON MOLLUSCA OF THE WEST COAST OF NORTH AMERICA. 549 



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

 ceived from Dr. Jay ; those in Mus. Haiiley 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. 



14. Tellina rosea, Lam. California. [Perhaps Sanguinolaria miniata.~\ 



33. Pecten tumidus, Brod. Upper California. 



87. Chiton incarnatusj Nutt. 



Chiton textilis, Conr. 



38. Patella plicata, Nutt. 



40. Fissurella pica, Nutt. 



41. Crepidula squamosa, Brod. 

 Sulla Californica, Nutt. 



68. Natica variolaris. California. 



70. Trochus Californicus, Nutt. Upper California. 



72. Monodonta fusca, Nutt. 



73. Marmorostoma planospira, Nutt. 

 Litorina iostoma, Nutt. 

 Litorina maculata, Nutt. 



79. Melongena occidentalis, Nutt, 



80. Murex sexcostatm, Bru^ 



86. Monoceros plumbeum, Kien. 



87. Buccinum Boysii, Nutt. n , 



54. C. B. Adams. After arranging the duplicate Reigen 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 written. The 

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

 Shells of Panama,' from the Type Specimens," written for the Zool. Soe. 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, Rep. pp. 267-280. The results in 

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

 (M.=Brit. Mus. Maz. Cat.) 

 3. Ovula neglecta=avena, var. 



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

 11. Cyprcea rubescens, C. B. Ad., = T. sanguinea, dead. 



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

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

 specimens of ccerulescens. 



33. Oliva araneosa, C. B. Ad.,= O. Melchersi, M. 591. 

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

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

 43. Nassa canescens=dead sp. of N.pagodus. 



50. Nassa pagodus, C. B. K,decussata, Kien. [ ? non. Lam.] = acttfa, M. 625. 



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



52. Nassa proximo +5 N. striata, C. B. Ad. [non Mus. Cum. = N.paupera, Gld.], 



+N. crebristriata, M. 633, are probably vars. of N. versicolor. 



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

 70. Purpura foveolata, probably = worn sp. of Cuma costata, M. 610. 



74. Pur pur a osculaw+Rh. Calif ornicus+Rh. distans, are probably vars. of Rhizo- 



cheilus mix. 



81. Columbella costellata, C. B. Ad.,=Anachis scalarina, Sby. 

 98. Columbella parva, C. B. Ad., = dead sp. of Anachis pyc/mcea. 

 103. Columbella tessellata, C. B. Ad. (non Gask.),=^4. Guatemalensis, Rve. 

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



from the Texan Bezoardica inflata. 

 154. Cancellaria affinis scarcely differs from C. urceolata, M. 445.
