34 EXOTIC CONCHOLOGY. 



APPENDIX OF THE BLIGH CATALOGUE. 



HALIOTIS GLABRA, (OF SWAINSON). 



Testa obtuse ovata, depressa, lata, obsolete striata, intus Isevi ; spira ampla ; labio exte- 

 riore rotundato : margine aiitico gibbo : foraminibus minimis, numerosis, ovatis, 

 sublsevibus. 



Shell obtusely oval, depressed, broad, obsoletely striated, within smooth : spire ample ; 

 exterior lip rounded, the top gibbous : perforations minute, numerous, oval and nearly smooth. 

 It is a native of the coast of New Holland, and is sometimes beautifully marked with large 

 angular veins of chesnut brown on a pale ground of greenish. 



H. CARINATA. 



Testa rufo alboque varia, costa centrali, transversa, intus concava, insigni ; spira ampla : 



foraminibus lineam convexam perforantibus. 

 Mart I. tab. 14. fig. 140. 



This and the shell improperly placed under a distinct genus by the name of Padollus Sca- 

 taris are the two species confounded under the Linnean sjinonyxn of Hal. Parva. I am not 

 certain as to its locality. The interior surface is faintly marked with fine lines, parallel with the 

 transverse rib and the whole shell is generally thin. 



H. RUFESCENS. 



Testa ponderosa. leviter striata, aliquando nodis sparsis deformi, rufescente : spira brevi ; 

 labii exterioris extremitate antica gibba : labio interiore angusto ; foraminibus 

 levatis, remotis (3 aut 4 apertis). 



Shell ponderous, obsoletely striated, sometimes defoi-med by scattered nodules, reddish ; 

 spire small ; outer lip at the top gibbous : inner lip narrow : perforations elevated, remote, only 

 three or four open. In proportion, as the back of the shell is worn down, the colour becomes a 

 brighter red. It attains to a very large size, and when in perfection is a beautiful species. In- 

 habits the Gallipagos and California. 



H. COSTATA. 



Testa convexa pallida, costis numerosis, integris, obtusis, longitudinalibus a spira diver- 

 gentibus in superficiem internam conspicuis : foraminibus numerosis, rotundis,vix 

 levatis.
