28 HALIOTIS. 



profunde lirata ; apertuni elongata, margine dentato, ad 

 terminum truucata. — The nearest in form to 11. asininus, 

 but sculptured with narrow but deep and wall-like sharp- 

 edged ridges. 



45. JACNENSis, f. 48, Reeve. — Testa oblonga, subaurantia, 

 profunde spiraliter lirata; spira parva, tuberculis foramini- 

 feris prominentibus, area marg'nali subdivaricatim rugosa. — 

 A curious little oblong species of a dull orange colour, with 

 very deeply cut ridges. 



46. VARiA, f. 5, 6, 7, 11, 12, 61, Linnceus. — Testa ovato- 

 convexa spiraliter striata coloribus variis frequenter radiatim 

 picta, liris subdistantibus insequalibus, hinc illic nodosis 

 rugata ; spira latiuscula exserta, area versus angulum fora- 

 miniferum laevigata ; foraminibus prominulis. — Varying very 

 much in form and colours, but agreeing in the general cha- 

 racter of the sculpture, which consists in an alternating 

 or irregular mixture of small spiral striae, with some larger, 

 having knobs at uncertain distances. In the variety named 

 aemistriata, Keeve, f. 11, on half the disc nearest the per- 

 forations the striae are obsolete. In Mr. Hanley's beautiful 

 specimen (f. 12) this is partly the case through a portion of 

 the semicircle, 



47. pusTULATA, f. 112, Reeve. — Testa H. varice similis sed 

 versus spiram lutior, subcomplanata antice attenuata, uodis 

 striisque minoribus. — The sculpture is finer, the spiral region 

 broader and flatter, and the anterior part narrower than in 

 H. varia. These differences are, however, of questionable 

 specific value, 



48. ASTRiCTA, f. 83, Reeve. — Testa H. varice similis, magis 

 oblonga, subconcentrice rugata, spiraliter tenuiter striata, vix 

 nodosa, pallida, viridi fuscoque subfasciatim variegata. — 

 Narrower than T. varia, pustulata, and with fine sharp 

 Ktria3 intersecting wrinkles and deep lines of growth. The 

 rugose sculpture is finer and closer, and wants the pustules of 

 2\ varia. 



49. CONCINNA, f. 46, 54, Reeve. — Testa complanata, sub- 

 ovata, postice lata, antice subattenuata, lactea, rubro viridique 

 variegata, spiraliter lirata, liris distantibus elevatis, undu- 

 latim nodosis inlerstitiis irregularibus tenuibus ; foraminibus 

 prominulis, parviusculis ; apice fere immerso. — The sculpture
