256 CONUS. 



the coast of Florida, it was named by Gabb in 1868, C. flori- 

 danus, and two years later by my father, G. jioridensis. 

 Most of the specimens I have seen are smaller, narrower, and 

 of lighter texture than the one figured. 



470. Fergusoni, Sowerhy (f. 675). — C. testa maxima, 

 ponderosa, alba, spiraliter leviter substriata, epidermide sor- 

 dide fusca crassa rugata induta ; spira subplanulata, latis- 

 sima, vix elevata, apice paulo exserto ; anfractus ad spiram 

 depressi, ad suturam irregulariter undati, inter suturam et 

 angulum obscure unicostati, ulfcimus subobtuse angulatus, 

 infra angulum leviter convexus ; ajiertura modica, fauce alba, 

 labrum vix sinuatum. 



A large white species, quite distinct from all its congeners. 

 Externally it is dull white, slightly roughened by spiral striae, 

 and longitudinal lines of growth ; the interior is shining white. 

 Several specimens have been collected at Panama by Mr. D, 

 W. Ferguson. 



471. Maltzanianus, Weinliaujf (f. 676-7). — C. testa tur- 

 binate, solida, transversim lirata, Kris simplicis vel granulosis, 

 distantibus, pallide lutea, interstitiis lirarum profundioribus, 

 bifasciata, basis profunde violacea ; spira obtuso-convexa, im- 

 maculata, anfractibus 9, planis vel subconvexis, leviter striatis, 

 apex tumidus 2^ anfr.; apertura latiuscula, intus violacea vel 

 purpureo-nigricante, labrum acutum, intus luteo marginatum, 

 superne vix sinuatum. (H. 0. WeinkaufF.) 



Allied to G. lividus^ but of more obtuse form, transversely 

 ribbed, ribs mostly granulated, especially those towards the base. 

 Hab. Tahiti. ' 



472. JiCKELii, Weinlauff (f. 678-9).— C. testa oblongo- 

 turbinata, laeviuscula, antice sulcata, albida, maculis nigris 

 elongatis et quadratis seriatim dispositis ornata ; spira sub- 

 plana, apice elevate ; anfractus 9, planiusculi, submarginati, 

 spiraliter striati, maculati, ultimus obtuse angulatus, infra 

 angulum leviter convexus ; apertura latiuscula, basim versus 

 paulo latior, fauce caerulea, labrum maculis nigris marginatum, 

 superne leviter sinuatum. Long. 51, maj. lat. 25 mill. 



Very much resembling G. proteus of the West Indies, but 

 having been found by Mr. Jickeli at Massaua in the Red 

 Sea it is probably distinct. Weinkauff describes the species as 

 having fulvous spots, probably from a dead specimen, his figm-e, 

 which I have copied, representing the spots black or nearly so.
