No. 17-n. WEST AMERICAN CONES DALL. 223 



is the C. arcuatus of Gray , well figured on pi. 36, fig. 22, of the Zoology 

 of Beechey's Voyage, 1839; hut it is nol the arcuatus of Sowerby in 

 1829. It is the C. lorenzianus of Kiener, [conography of ('onus. pi. 

 55, fig. 1; and of Reeve, Conchologia Iconica, pi. 27, fig. 152, 1843, 

 but not of supplementary pi. 5, fig. 241), 1849; nor of Dillwyn, 1 s ] 7 . 

 C. flammeus Lamarck, C. zebra Sowerby (Conch. 111., fig. 1, 1833) and 

 of Reeve, 1843; and C. virgatus Reeve (Conch. Icon., (onus, pi. l(i, 

 fig. 87, 1843); all of which have been associated with this species, are 

 perfectly distinct from it, though perhaps not from each other. The 

 purple-brown flames which longitudinally ornament this shell are 

 angularly interrupted near the middle of the side, showing a tend- 

 ency toward a spiral hand in that place. 



CONUS ARCHON Broderip, 1833. 



Mazatlan, Acapulco, west coast Central America. 



The shell figured by Sowerby in the Conchological Illustrations is 

 apparently not that subsequently described and figured by Kiener 

 and Reeve. Our shell agrees with Sowerby's original diagnosis and 

 figure; which he pointedly states has "no articulate lines." The 

 granulate shell, C. granarius Kiener, is quite distinct from the true 

 Archon as well as from Archon of Kiener. The latter is probably the 

 same as his C. sanguineus. Of the relations of his C. castaneus I am 

 doubtful, but see no reason for approximating it to C. archon. 



Our shell has irregularly distributed chestnut brown flammules on 

 a white ground with a few brown spiral lines near the anterior end, 

 more or less broken, but not "articulated." The surface is smooth; 

 there is no trace of granulation. The spire is rather tumid and nol 

 much elevated. 



CONUS ARCUATUS Sowerby, 1829. 



Cerros Island, Lower California, south to Panama. In mud at a 

 depth of 14 to 50 fathoms. 

 This is another species in which the original type seems to have 

 been disregarded. In the Conchological [llustrations, soon after the 

 species was described, it was figured by Sowerby in a very character- 

 istic manner. The arcuatus of Gray, 1839, already alluded to, is a 

 totally different species, C. emarginatus Reeve, which is founded on 

 (Iray's figure. Reeve figures a rather dark specimen of the present 

 species in the Conchologica Iconica, Conus, pi. 15, fig. 776. Numer- 

 ous specimens were dredged by the fisheries steamer Albatross. In 

 general the white part of the shell predominates over t he brown flam- 

 mules. The spiral sulcation found at the base frequently extends 

 nearly to the shoulder, while other specimens are almost smooth. 



CONUS EDAPHUS Dall, new species. 



Oil' Clarion Island in 31 fathoms, sand; bottom temperature 

 68°.4 F.; U. S. Bureau of Fisheries steamer Albatross. 

 Shell small, short, stout, solid, with a short acute spire, rounded 

 shoulder, and slightly convex sides; nucleus of two and a half trans-
