Show 1891.] MR. E. A. SMITH ON NEW SPECIES OK SHKLLS. 487 CONUS INNOTABILIS. (Plate XL. fig. 1.) Testa parva, albida, fiammulis longiiudinalibus irreqularibus fuscis vel rufescentibus picta, transversim anguste sulcata, sulcis longitudinaliter strialis, subpunctatis, quam interstitiis planis longe angustioribus ; spira breviter conica rufo maculata ; anfractus declives, plani, sulcis spiralibus tribus sculpti, sutura sub canaliculata sejuncti, ultimus superne obtuse angulatus, infra angulum lateribus levissime convexis, antice subconstrictus; apertura angusta, sordide albida vel pallide fuscescens. Longit. 18 millim., diam. 10. Hab. Rocky Point, four miles north of Richmond River, N. S. Wales; also Port Stephens near Sydney (Brazier). This is an insignificant-looking species without any very marked features. The coloration is indefinite, but the spiral sculpture is well-marked. The sulci are scarcely half as wide as the spaces between them, which are flattened, and about twenty-four in number on the body-whorl. MITROMORPHA BRAZIERI. (Plate XL. fig. 2.) Testa ovato-fusiformis, spiraliter tenui-striata, lineis incrementi sculpt a, pallide fuscescens, lineis tiansversis albo et rufo articulatis indistinctis, picta ; anfractus 5, supremi duo (nucleus) magni, globosi, Iceves, nitidi, cornel, ccxteri sutura distincta leviter obliqua sejuncti, ultimus elongatus, antice parum contractus ; apertura elongata, intus pallide fuscescens, antice late canaliculata, longit. totius superans ; labrum tenue ; columella superne leviter concava, infra oblique torta, callo tenui nitente induta. Longit. Gk millim., diam. 3/ apertura 3g longa, 1| lata. Hab. Off Green Point, Watson Bay, Port Jackson, in 8 fathoms, on a bottom of broken shells, sand, and small stones (Brazier). From the large size of the nucleus of this shell it was thought that possibly it might be the young state of some largish species. Howevrer, none were found with which it could be satisfactorily identified. The most distinguishing feature is the broad open anterior canal and the oblique lower portion of the columella. I have placed it temporarily in the genus Mitromorpha, as it has spiral sculpture, the anterior canal, and the general form of that group of Pleurotomidce. The operculum is unguiculate, and nearly two thirds as long as the aperture. LITTORINA ACUTISPIRA. (Plate XL. fig. 3.)
