Cyclostoma Rafflesii. 



C. testd spird depressiiisculu, anfractibus quatuor rotundatis, superne 

 striatis, carinis 4 ad 6; iimhilico mag no ; aperturd orbicidari, 

 peristom.ate rejlexo ; long, l-,^^ poll. lat. 2 poll. 

 Hah. in Sumatra. 



The first specimens we saw of this fine Cyclostoma were brought to 

 England by Sir Thomas Stamford Raffles, in honour of whom we have 

 named the species. Its upper side is of a fine chestnut colour, prettily 

 varied with white. In its very young state it is quite destitute of the 

 keels, but has only close-set transverse striee : the reflected lip is some- 

 times of a light orange brown colour. 



Cyclostoma Perdix. 



C. testd spird depressiuscidd, acuminatd, anfractibus quatuor^ leviler 

 striatis ; carina media, cetate obliteratd ; aperturd ampld, peristo- 

 mate rejlexo ; umbilico mediocri ; long. -^^ poll. lat. 1 -^q poll. 

 Hab. in Tennasserim. 



A very elegant species, of which a single specimen was brought to 

 England by Mr. Hay, who found it alive in Tennasserim, not far from 

 the shore. It is of a dark chestnut colour, mottled with white, and 

 there is a sutural band of chestnut articulated with white. We have met 

 with other specimens which show that the keel, which is always sharper 

 in the young shell than when at its full growth, is sometimes not deve- 

 loped at an early period. 



CONUS SOLANDRI. 



[Tab. Supp. xl. f. 4.] 



C. testd cylindraceo-turbinatd, subcoronatd, striis transversis freqaen- 

 tibus, basalibus granulosis, fulvd, fascid medid alba, castaneo 

 maculatd et punctatd ; spird mediocri, striata. 

 Hab. ad Taheite. 



The specimens of this pretty Cone, which were brought home in the 

 Endeavour, are in a very bad state, the points of the spires being ground 

 off, apparently for the purpose of stringing them. They are labelled, 

 " Otaheite," in Dr. Solander's hand- writing. Our specimen, which is 

 in high perfection, was brought home in the Blossom ; but we know not 

 where it was found. In Mr. Sowerby's collection.
