232 SOLARIUM. 



basalis in junioribus fere pliciformis. Obs. The acquisition, by 

 Mr. Taylor, of all the original specimens of Solaria, described by 

 Hinds, from Sir E. Belcher's collection, has enabled me to identify, 

 by a long chain of connecting links, the immature fragilis of that 

 naturalist with the adult pictum of Philippi. The type of the 

 former was sharply carinated, nearly white, with the fourth belt 

 continuously and the first interruptedly brown; the prominent 

 radiating riblets of the white lower disk are obscurely cut towards 

 the umbilicus by a faint spiral groove ; the umbilical teeth are 

 smaller and more numerous. The mere fry are. not unlike the 

 top of S. quadriceps, but the great length of the third row of 

 grains distinguishes them. The adult appears to have been known 

 to both Seba (iii. pi. 40, f. 41, 42) and Chemnitz (f. 1694, 

 copied in Kuster's edition, Sol. pi. 2, f. 4), although I dare not 

 positively pronounce upon their somewhat rough drawings. 



11. Cumingii (f. 44, 45), lianley. — T. subdepresso-conica, 

 albida seu pallide fulva, infra sulcum spiralem zona lata subma- 

 culosa picta : dimidium inferius anfractuum majorum seriebus 3 

 macularum linearium brunnearum ornatum. Anfractus sulcis 

 (nisi labrum versus) subconfertis radiati, et sulco unico spirali 

 infra cingulum album (margine superiore brunneo submaculoso (?) 

 passim ornatum) superne instructi ; pars inferior arese media; 

 costellis tenuibus obsolete cincta : cingulum marginal e (seu infe- 

 rius) nullum. Carina parva, angusta, brunneoque maculata. 

 Basis albse area media, tantum umbilicum versus modicum et crenis 

 rutis permultis munituin punctis picta : cingulum infraperipherale 

 procul a carina, angustum, tantum obscure maculatum. 



12. purpuratum (f. 7, 8), Hinds. — T. srepius depresso-conica, 

 striis confertis radiata. Anfractus sutuni angusta divisi, sulcis 2 

 (quorum superior fortasse est major) ciucti, pallide cserulescente- 

 purpurei, maculis rufis (stepe flammas simulantibus) ad carinam, 

 cingula, zonas 2 superiores anf. ultimi penultimique plerumque 

 etiam ad cingulum anf. creterorum primum (aliquando omniuo 

 album), ubi, sicut in cingulo suprasuturali macuhe magna; fiunt 

 et distantes, ornati. Cingulum sulcum peripheric perangustum et 

 nonnunquam filosum prrecedens, satis latum (sfepe latius quam 

 ipsa carina). Basis media maculis brunneis undatis satisque 

 magnis (aliquando vel concurrentes strigas radiantes formant, vel 

 oritur series interveniens) utriuque marginata. Sulcus inter cin- 

 gula basis externa satis latus, uuifilosus. Crense umbilici, nun- 

 quam late pateutis et in var. elevata coarctati, brunnea^'multa;, 

 satisque magnse. Obs. The elevated form has a slight fulvous
