Show 1880.] MR. E. A. SMITH ON NEW SHELLS. 479 sulcos elevatis conspicuis. Inflatio basalis nulla. Labrum tenue, superne et inferne arcuatum, in medio rectiusculum. Sinus sub-suturalis latus, profundus. Apertura alba, supra et infra sub-eequaliter lata. Long. 88 mill., diam. 49. Hab. 1 (From Mr. Lombe Taylor's collection.) The outlines of the spire are straight, converging to an acute apex. The upper part of the whorls has been attacked by a boring annelid to such an extent as to destroy almost entirely whatever sculpture may have existed. As far as can be traced, there appear to have been one or two small spiral grooves, fine striae in the same direction, and flexuous lines of growth. The shallow grooves give the whorls a somewhat concave aspect. The light-brown bands are not well defined ; the uppermost is very broad, and falls just above the middle of the whorl; at this point there is a white zone, beneath which are two ill-defined and somewhat confluent bands. The portion of the volution above the uppermost zone is in some places also suffused with light brown. C. fulvocinctus, Crosse, is the nearest ally of this species. In form it is not so attenuated at the base, the spire is less elevated, and its epidermis is described as rather thin, whilst that of C. consanguineus is very thick and firmly attached; the latter, too, has a rosy apex and more of the light fulvous transverse banding. CONUS NEPTUNOIDES. (Plate XLVIII. fig. 2.) Testa conica, roseo-albida, lineis fuscis irregulariter reticulata, paululum supra pauloque infra medium fascia lata, interrupta indistincta ejusdem coloris cincta. Spira elevata, concava, gradata, lineis contortis fuscis radiatim picta. Anfractus circiter 10, superne declives, leviter excavati, striis tribus spiraliter sculpti incrementique lineis arcuatis striati, inferne angulati. Anfr. ultimus superne rotunde angulatus, infra angulum aliquanto convexus, delude rectiusculus, transversim tenuiter striatus, infra medium sulcis angustis remotis 10-12 oblique sculptus, ad basin supra columellam oblique inflatus. Apertura mediocriter lata, inferne aliquanto latior, intus dilute rosacea. Labrum obliquum, superne infra sinum haud profundum leviter arcuatum, in medio rectiusculum. Columella infra inflationem anfractus rectiuscula, callosa. Long. 45 mill., diam. 20. Hab. Australia. (From Mr. Lombe Taylor's collection.) The pattern upon this shell consists of an irregular network of brown lines, more or less disconnected. This reticulation becomes rather coarser and blotched with brown both above and below the middle of the last whorl, thus forming two broad, but ill-defined bands. This species is allied to C. neptunus, Reeve, but rather broader, and has fewer striae upon the spire. The oblique linear sulci extend only about halfway up the body-whorl, whilst in C. neptunus they are observable to the top. The painting, too, is rather different. |
