N<>. 1711. WEST AMERICA* CONES— DALL. 227 



Our presenl shell has a dome-shaped spire with a small acute 

 nucleus, irregular suture, the summit of the whorls behind the 

 shoulder being closely and continuously striate. The body color is of 

 a pale reddish brown, intensified at resting stages. The lines of 

 growth on the sides are minutely wavy, crossed by a multitude of 

 almost microscopic striae, with indications over the surface of more 

 extended but obsolete spiral sulci corresponding more or less closely 

 to line dark-brown spiral hair lines, and about nine spiral threads 

 with wider interspaces near the canal. The shell is about 50 mm. in 

 length and 25 in maximum diameter. 



Whether this specimen is really Oriental and wrongly labeled from 

 Acapulco, or whether it represents Sowerby' s original and a distinct 

 species from the Oriental shell I have no present means of deciding. 



It will be noted that the geographical distribution given for the 

 species of the preceding list, except when put in parentheses, is based 

 on specimens actually in the collection, and not on the literature. 

 There are several species referred to the Pacific coast in the lit era t ure, 

 which are not represented in the list, because we have no autoptical 

 information to that effect. 



There are some species which have been associated with the 

 Pacific coast fauna, but are not definitely admitted to our list. Notes 

 on these follow. 



Specimens of Conus proteus from Panama are in the collection. 

 They doubtless were purchased and originated on the Atlantic side. 



A fresh shell of Cjlavidus Lamarck, was sent by a correspondent 

 as picked up at San Diego, California. It is without doubt exotic. 



Conus concinnus Broderip, not Sowerby, renamed by Grosser. 

 condnnulus, is a species of Meta, belonging to the Columbellidae, and 

 a common Gulf shell. 



Conus ductus Valenciennes, 1832, not of Swainson, 1823, may be 

 the same as emarginatus Reeve. 



Conus tiaratus Broderip, is regarded by some authors as identical 

 with C. minimus Linnaeus, which is improbable. 



Conus luzonicus Valenciennes, has been reported from the Gala- 

 pagos Islands, but its real habitat seems to be t he Philippines. 



Conus diadema S< >werby, 1834, is a variety of C. brunneus Mawe. 



Conus reticulatus Sowerby, 1833, from Magdalena Bay, is identical 

 with C. lucidus Mawe, 1828. 



Conus corfebs Hinds, may be the young of ( '. fergusoni Sowerby. 



Conus trochulus Reeve, reported from California, is really from the 

 Cape Verde Islands. 



Conus pevplexus Sowerby, in the Thesaurus, lN. r )7, is identical with 

 C. comptus Gould in 1851.
