Solarium, Lamarck. 



At the sale of the collection of shells of Mr. Imwood, several lots of 

 Solarium came into my possession ; and as it was a, favourite group 

 with this gentleman, he, as might naturally be supposed, had assem- 

 bled together many very interesting specimens. The full suites of 

 some of the species have enabled me better to draw a line of distinc- 

 tion between them, and has afforded grounds for regarding several of 

 the following as perfectly distinct and hitherto undescribed species. 

 In addition to the above, I have had before me the collections of Sir 

 Edward Belcher and Mr. Cuming, both rich in novelty, but more 

 particularly in the careful and accurate detail of localities and cir- 

 cumstances of habitation. The whole permits me to record fourteen 

 new species in a genus which previously seemed to contain about 

 fifteen recent and forty-nine fossil species. 



1. Solarium formosum. Sol. testd orbiculato-conicd, politd, fas- 

 ciatd ; anfractibus subtumidis, superne sulco unico divisis, infe- 

 rioribus Icevigatis, spirce plico -striatis, superne fusco, albo, et atro- 

 fusco deinceps fasciatis, medio subcorneis ; ad basin planulatd, 

 aperturd quadratd; umbilico patulo, crenis rectis, subacutis,fus- 

 catis ; ared umbilicali laid, sublcevigatd. Djam. 1 8, umbilic. 3J lin.

Hab. Amboina. Cab. Hinds. 



This fine shell has hitherto, most probably, been considered only 

 as a variety of the well-known species S. perspectivum ; it is how- 

 ever sufficiently distinct. In shape it is considerably more elevated 

 and conical, and it is ornamented with rich fasciations of brown and 

 white. Near the upper part of each whorl a narrow sulcus separates 

 a narrow portion. The base is flattened and polished ; umbilicus 

 moderately dilated, being less so than in S. perspectivum, and armed 

 on the margin with a row of straight sharp crenules, on their right 

 faces of a darker brown colour. The umbilical area, or the space 

 between the spirally twisted row of crenules, is smooth, except for 

 the arched striae of growth.
