CONCHOLOGY. 



racter testa minore, granulata ; it differs materially in size, being 

 little more than an inch in length, but the markings are similar, the 

 spots in this kind being nearly as large as in the full-grown Conus 

 Marmoreus, they are necessarily fewer in number and appear con- 

 siderably larger in proportion. The granulations to which that 

 author refers are disposed in circles round the shell, forming 

 altogether about thirty equidistant granulated bands, a character of 

 some singularity in a species which is remarkable for the smoothness 

 and politure of its surface, if we except the variety /3. of Gmelin, 

 which is described as being finely striated, testa subtiliter striata, 

 and (e) of the Lamarkian kinds. Lamarck's variety (c) testa nigro 

 bizonata, is the example shewn by Rumphius and Seba, with two 

 black zones or bands, a shell of equal size with the common variety, 

 or type of the species. The variety (d) testa Uneis duabus albis 

 cincta is the kind already introduced to notice in the work of 

 Chemnitz, and which instead of two black zones is encircled with two 

 distinct white lines. The fifth and last variety of the species 

 is distinguished by Lamarck as testa maculis albis longitudi- 

 nalibus subfasciata. The novelty of this variety consists in the 

 form and disposition of the spots of white ; they are much elongated 

 longitudinally, and are so disposed as to form about three distinct 

 bands across the shell, besides two or three others, in which the spots 

 are not more lengthened than in the other varieties. Lamarck has 

 omitted to mention one character of this variety which it is material 

 to consider, namely, the fine striae or lines with which the shell is 

 girt or encircled transversely. — Amidst all the apparent confusion 

 that may be conceived to exist among the varieties of this shell it will 

 not be forgotten that the several varieties are at once reducible to
