are very much broken up by the confusion of white 

 spots, and the net-work which covers the rest of the 

 surface differs essentially from that in any other. It is 

 exceedingly irregular, forming triangular spots of all 

 dimensions, miscellaneously intermingled.

Conus Sumatrensis. Con. testa subobeso-conicd albi- 

 do-lutescente, lineis Iritis, fuse is, longitudinaliter con-

The longitudinal markings of this shell are very cha- 

 racteristic.

Conus dux. Con. testa cylindraceo-conicd, rubido-fusco

I am unacquainted with the yellow variety from the 

 collection of M. Hwass, described and figured in the 

 'Encyclopedie Methodique,' and copied by Lamarck, and 

 Schubert and Wagner ; it might probably have been a 

 worn specimen.

Conus floccatus. Con. testd ovato-conicd, lacco-rubido 

 nebulosd et leviter undulatd, lineis b>-evibus longitudi-

The snow-flaked Cone. Shell ovately conical, clouded 

 and lightly waved with a ruddy lake-colour ; trans- 

 versely filleted with short longitudinal lines, and 

 more or less sprinkled with irregular white spots 

 like flakes of snow.

This beautiful shell has been confounded by some 

 authors with the Conus dux.
