26 HALIOTIS. 



sculpta. — This sliell does not differ vei-y greatly from some 

 variations of //. nebulata. It has a more elongated form, 

 and a different character of marking. 



35. NEBULATA, f. 8, 56, Rcsve. — Testa oblongo-ovata viridi 

 fuscoque nebulata, convexa, laevigata, inter liras planatas 

 inciso-striata ; spira angusta, subterminali, exserta ; area 

 marginali rotundata acute lirata. — Oblong-ovate, green and 

 brown, clouded with generally undefined spots, sculptured 

 with incised strise defining flat ridges. Spire small, promi- 

 nent ; holes small. H. revelata, of Deshayes (56) found on 

 the shores of the Mauritius, is plainly identical with this. 



36. ASiNiNA, f. 3, 4, Linncciis. — Testa elongata, angusta, 

 arcuata, laevigata, utrinque tumida, medio depressa, postice 

 acuminata, antice subtruncata, versus spiram distanter lirata, 

 glauca, viridi vel fusco angulatim variegata ; area marginali 

 leviter distanter lirata ; intus argentea, labio externo medio 

 sinuoso ; labio interno tenui, erecto, foraminibus majusculis ; 

 spira parva, terminali. — This long and elegantly arched species 

 is well known, and the propriety of its name acknowledged. 

 The side nearest the suture is swelled in its whole length, the 

 middle depressed, and the other side rounded. The apex is 

 nearly terminal and acuminated, and the anterior end is 

 truncated. 



37. Hanleyana, f. 28, Soioerhy. — Testa rubro variegata, 

 intus argentea, rugosa, anguste subtrapezoidea, concentrice 

 rugis crassis elevatis undulatis laminata, spiraliter elevatim 

 lirata, liris insequalibus, subalternatis ; spira acuta, valde 

 elevata, anfractibus angulatis ; area marginali tuberculatim 

 costata. — Laminated more thickly and roughly than H. la- 

 mellosa, and chiefly remarkable for its exserted and elevated 

 spire, in which respect it resembles H. stomaticeformis. 

 I am indebted for this beautiful species to Mr. Sylvanus 

 Hanley. 



38. STOMATi^FORMis, f. 22, 23, Reeve. — Testa oblique 

 oblonga subtrapezoidea, spiraliter inciso-striata, versus spiram 

 tumida, concentrice liris elevatis rugata ; medio depressa 

 ad angulum acuta, tuberculis parvis ; pallide fulva, maculis 

 angulatis aurantiacis variegata ; spira elevata exserta, an- 

 fractibus angulatis; apertura antice subquadrata. — This shell, 

 like H. Hanleyana and //. elevata, has the spire mucli 

 raised, so as to resemble Stomatia phymotis. The variety
