330 WEST SOUTH AMERICAN SHELLS — STEARNS. 



from La Paz and the Gulf of California to Dr. Jones's southernmost 

 locality, or from 24° 30' ]Sr., to 5° 15' S. latitude. Colonel Jewett col- 

 lected it at Acapulco, where it was also obtained by myself in May, 

 1868. Mr. W. J. Fisher found it living at the Tres Marias group at 

 the mouth of the Gulf of California.

Several beach shells. 



Payta; Gua^'aquil; Manta. 



An exceedingly variable shell for one of this group, but nevertheless 

 having a common facies which, when a large series is brought together, 

 satisfactorily indicates the reasons for the above synonymic arrange- 

 ment. Try on (Manual) gives the distribution, " West coast of America 

 from Gulf of California northward," but Cuming obtained it at "Punta 

 St. Elena," which is on the coast of Guayaquil in lat. 2° 10' S. It will 

 be seen that Dr. Jones's collection carries it still further south to lati- 

 tude 5° 15'. Carpenter, in the "Mazatlan Catalogue," credits it to 

 Sitka, on the testimony of Wosnessenski in Middendorfif; this is no 

 doubt an error, as to its actual northerly range; though it is not im- 

 j)robable that a dead shell might have been obtained there, from either 

 ballast refuse dumped overboard or from its having been dropped by 

 some sailor belonging to a whaling ship; for the whalers formerly 

 cruised all along the coast from Magdalena Bay, Lower California, to 

 and through the Alaskan waters. 



Carpenter also credits T. jiuctuosus to San Diego, California; this 

 has not been corroborated by any sabseiiuent collector, though it is not 

 improbable that Lieutenant Green may have detected it at this place 

 for the species extends northerly along the outer coast of Lower Cali- 

 fornia, where it has been detected at various places as well as at Cerros 

 Island. 



185. Turbo (Callopoma) saxosus Wood. 



Several examples ; beach. 



Payta; Manta; Panama. 



Tryon refers to T. nitzschii Anton ("al/t^2;c/m Anton " Sby.) and T. 

 venustus Phil., as synonyms. 



The National Museum collection shows tne range to be trom Payta 

 as above northerly to Cape St. Lucas and up tiic (inlf of California to 

 Guaymas, where it was collected by Dr. Edward Palmer several years 

 ago.
