sition of character to be seen in tlie after-growth. A valu- 

 able specimen in the possession of Mr. Hanley illustrates an 

 intermediate stage of growth. On the whole, the evidence 

 of identity is not absolute. 



9. IRIS, f. 24, 25, Gmelin. — Testa ovalis oblonga fusco- 

 viridis, rugis oblique radiantibus et liris spiralibus, inter- 

 stitiis concavis sculpta, spira parva, subterminali, apertura 

 vivide ca3ruleo, purpureo, viridique iridescenti, labio interne 

 lato, planato. — The obliquely radiating wrinkles and decussat- 

 ing striae tend to form symmetrically arranged pits between 

 tliem. In the brilliant iridescence of the interior, green and 

 purple prevail. 



10. viRGiNEA, f. 92, Chemnitz. — Testa convexa, ovato-ob- 

 longa,fusco-viridis,albo fu]gurata,spiraliter granoso-lirata, ob- 

 lique plicata, spira subterminali, foraminibus, vix exsertis, 

 area marginali declivi ; apertura viride iridescenti, tenuiter 

 rugata. — This shell is unmistakably figured in Cherinnitz as 

 H. virginea. Dunker has seen this and figured it beau- 

 fuUy. Eeeve applied the name to a shell which is plainly 

 the true marraorata of Linnreus, and followed Philippi in 

 giving the name of H. Gihha to the present species. It 

 is an oval shell, having a sort of ' quilted ' texture, and a 

 beautiful green iridescence within. 



11. GrRAYANA, f. 87, 111, Soiuerby. — Testa ovata, con- 

 vexiuscula subdepressa, spiraliter depresso-costata, subviride 

 fulva, maculis postice marginatis variegata, labio externo 

 circa spiram expanso et extenso ; spira subterminali. — The 

 supposed identification of this species as H. TYiarmiorata of 

 Linnaeus by the late Dr. Gray must be regarded as a mistake. 

 The characters given do not identify it, and there are no 

 specimens of it in the Linnaean collection, whereas the early 

 conchological writers, including Grmelin, refer to Martini's 

 fig. 139, t. 14, v. 1, as illustrating the Linnaean species, and 

 that figure corresponds with specimens in the Linnasan cabinet. 

 //. Gray<(,ii<L is a finely marked shell with spiral grooves, 

 rather flat, and remarkable for the manner in which the 

 outer lip coils round the spire at the suture. 



12. SPLENDENS, f. 37, 38, 105, 106, Beeve.— Testa, magna, 

 fusca vel fusco-viridis ovalis, depressa, solida, concentrice 

 tenuiter striata, spiraliter plano-lirata, liris latis, tenuissime 

 crenatis, interstitiis angustis planatis; spira subterminali, sub-
