Show 184 MR. E. A. SMITH ON MOLLUSCA FROM JAPAN. [Feb. 18, under them, so that the upper series might be said to be by the spiral furrow which separates them. The general tone of the shell is light brown or fawn ; but a few of the upper whorls are of a more or less lilac tint. The variety, from its slenderness and different coloration, appears at first sight almost specifically distinct; its sculpturing, however, is of precisely the same character as that of the typical form. The painting of T. alveolata, Hinds, resembles that of this species very much ; but its sculpture is a great deal coarser. 3. TEREBRA JEFFREYSII. (Plate XIX. fig. 2.) Shell subulate, dirty yellowish, dotted and streaked with light brown. Whorls 13 to 14 ; the two nuclear ones proportionally very large, globose, white, shining; the rest flat, bearing numerous oblique, but little raised fine costae (about 20 on a whorl), and spirally striated, the striao cutting through the riblets and giving them a nodulous appearance : the striae number about five on a whorl; of these the two uppermost are twice as far apart as the three following, and consequently the spaces between them are wider and more conspicuous ; the ends of the costae cut off by the two uppermost striae are prominently nodulous, and form two distinct series of granules, whereof the upper are more elongate than the lower. The body-whorl is but very faintly angled at the middle; the costse upon it terminate abruptly at tbat part, and are only continued to the base in a very obsolete manner; thus the lower half of the whorl is comparatively smooth to the upper portion, and the spiral or concentric striae are also less pronounced than those above. The aperture is small, light brown, and exhibits traces of one or two pale narrow zones. The canal is short, oblique, and slightly recurved : the columella is straight or nearly so in the middle and oblique at the base, and covered with a thin, shining, whitish callosity. Length 25 millim., diam. 5. Hab. Stations 20 and 21. This species is remarkable on account of the unusually large size of the nuclear whorls. The colour is rather indistinct, as most of the specimens are more or less coated with a cretaceous deposit; however, it appears to be luteous or dirty yellow, dotted with light brown between the two series of nodules, and streaked with the same colour beneath, and the body-whorl has a pale zone at the middle. 4. TEREBRA TORQUATA, Adams & Reeve. Terebra torquata, Adams & Reeves, Voy. Samarang, p. 30, pi. fig. 13 ; Reeve, Conch. Icon. vol. xii. fig. 69. Hab. Station 14. China Sea (A. Adams). This species must not be confounded with T. fenestrata, Hinds. The latter is very similarly sculptured, but lacks the variegated painting of T. torquata. 5. TEREBRA TEXTILIS, Hinds.
