Philippines (Cuming); Straits of Macassar (Hinds) ; Ovalau, Fiji Islands (Macgillivray in Brit. Mus.). 6. TEREBRA SUBTEXTILIS. (Plate XIX. fig. 3.) Shell subulate, entirely white : whorls probably about 22, the few apical ones being broken off; they are a little convex, finely ribbed, and spirally grooved ; costae about 20 on a whorl, arcuate, constricted a little below their upper extremities by a spiral furrow, which in the interstices between the ribs is comparatively deeply pitted ; transverse striae rather deep, more or less obsolete on the costae, about ten in number on a whorl, whereof three are above the pitted sulcus, and the rest below it; the ribs on the last whorl are arcuate above and flexuous at the base, to which they attain; the lower part of the whorl is also transversely sulcated like the upper portion ; columella covered with a distinct callosity ; canal short, rather broad and recurved. Length 37 millims., diam. 6. Hab. Station 21. This species to a certain extent has the characters of T. textilis, Hinds. From it, however, it may be known by its more convex and broader whorls, its greater size, and the more numerous spiral sulci or stria?, which in this species are present on the infrasutural band as well as below the pitted groove, whilst in T. textilis they only exist on the latter portion of the whorls, leaving the upper part plain, with the exception of the cut-off terminations of the costae. These striae are of different magnitudes, so that the interstices also vary in size and also in their degree of elevation. The sculpture of T. poly-gyrata, Desh., is similar in character, but much finer. That, too, is a coloured species and smaller. 7. TEREBRA TANTILLA, Smith. (Plate XIX. fig. 4.) Myurella tantilla, Smith, Ann. & Mag. Nat. Hist. 1873, vol. xi. p. 270. Myurella pumilio, Smith, I. c. p. 269. Hab. Station 21. Persian Gulf (Col. Pelly in Brit. Mus.). The specimens described under the name of T. tantilla were in bad, faded condition; and hence it was that the third band on the body-whorl escaped observation. I am now convinced of the identity of P. tantilla and T. pumilio. 8. TEREBRA ALBOZONATA, Smith. (Plate XIX. fig. 5.) Terebra albozonata, Smith, Ann. & Mag. Nat. Hist. 1875, vol. xv. p. 415 ; I. c. 1877, vol. xix. p. 226. Hab. Station 27- Matoza Harbour (/. c ). It is satisfactory to have obtained a second, although young, example of this species agreeing perfectly with the type. I take this opportunity of changing the name of a species of |
