might perhaps be referred with equal probability to G. fiavescens Gray. Bottom 

 temperature, where found, 77° F. 



Conus centurio is however found in the Antilles and Gulf of Mexico. A 

 specimen was collected by the U. S. Fish Commission at Station 2373, in 25 

 fms., between the mouth of the Mississippi and Cedar Keys, Florida. 



Conus fiavescens Gray. 



C. fiavescens Gray, Sow., Conch. 111., fig. 68, 1841 ; Reeve, Conch. Icon. Conus, pi. 

 XXX. fig 168, 1843. 



Specimens agreeing with the above figures have been received from Governor 

 Rawson and two other sources, from the Bahamas; though Tryon in his mono- 

 graph queries Ceylon and Australia for the species. Young specimens are 

 extremely variable in painting, but generally with a central more or less well 

 defined paler band ornamented M'ith a few brown blotches or dots. One is pure 

 white with a faint purplish tinge at the anterior end of the shell. The epider- 

 mis is thin, nearly smooth, translucent. Such young shells were collected by 

 the Blake at Santa Cruz, Station 132, 115 fms., hard bottom; Grenada, Sta- 

 tion 247, 170 fms. ooze; and Barbados, Station 290, 73 fms., coral; bottom 

 temperature 54-71° F. Some of them were quite fresh, and though not con- 

 taining the animal when received by me, looked as if they might have been 

 living when collected. Reeve's figure of G. magellanicus Hwass looks very 

 much like some of these young shells. 



Among the species which are definitely known to inhabit the Floridian re- 

 gion and Antilles and not previously mentioned here, are the numerous vari- 

 eties of G. pygmceus Reeve, one of which has been named G. Melvilli by the 

 late Mr. Sowerby. G. columba Brug., G. jpusio Lam., and G. papillosus Kiener 

 probably belong hereabouts. 



Conus fioridanus Gabb was named floridensis by Mr. Sowerby, who mixed 

 it up with C. Pealii. G. verrucosus and G. mus are among the commoner 

 Antillean species, and I have, from various parts of this region, G. nebulosus 

 Sol., which indulges in some extraordinary variations, C. achatinus Lam., and, 

 most interesting of all, Conus Delesserti Recluz, from a variety of stations. 

 This last is a Red Sea species, closely related to G. centurio as is C. daucus 

 to C. fiavescens. 



A beautiful species with very much the color of roseo-tinctus Sowerby, but 

 with the form and size of suhcarinatus Sowerby (see Thes. Conch. Conus, pi. 

 xxv. figs 604 and 615), the dark streaks longer and darker than in roseo-tinctus 

 and always followed by an equivalent pale area, a thickish epidermis, and the 

 top of the whorls excavated and striated, was dredged in 27 fms., near the 

 coast of Yucatan, by the Fish Commission, and has been named by me Conus 

 amphiurgus.
