Show 108 MR. J. BRAZIER ON NEW MARINE SHELLS. [Feb. 10, thorax and falces being rather darker than the legs and palpi, and the abdomen having a duller whitey-brown hue ; the hinder part of the caput is elevated or protuberant, the thoracic portion and sides being depressed; the eyes are similarly placed to those of the foregoing species ; those of the two foremost rows form an oblong figure, whose width is considerably less than its length, and its fore extremity a little wider than its hinder one; the two central eyes of the hinder row are much further apart from each other than each is from the lateral on its side; the eyes of this row are of a bright pearly-white lustre, and larger than the rest (which are dark-coloured), the external ones being apparently the largest of the eight. From the centre of the long-oval figure formed by the six hinder eyes springs a long, tolerably strong, erect, black bristle, and from the highest part of the caput (behind the eyes) spring two other similar bristles directed forwards; the legs are short, strong, and taper rapidly to their extremities; those of the third pair are rather the strongest; they are armed with hairs, bristles, and strong spines, the latter being especially beneath those of the first and second pairs; their relative length is 4, 3, 1, 2, thus differing in this respect from all the foregoing species; but there seemed very little, if any, difference in length between those of the first and second pairs. Each tarsus ends with three claws, the inferior one being very small, the superior pair having apparently but one strong tooth beneath, like those of Idiops petitii; the falces are strong, prominent, and armed with a group of powerful spines at their extremities on the uppersides. The maxillee are furnished with bristles and short spine-like prominences, of which last there are also several at the apex of the labium. The abdomen is rather large, oval, and convex above, furnished sparingly with hairs, and of a whitish yellow-brown colour. Spinners four in number; the superior ones stout, biarticulate, but not very long; the inferior ones very small. This Spider was dug out of a bank close to Beirut, by myself, in May 1864 ; it was in a tubular web spun in a cylindrical hole formed in the earth, and closed at the entrance, on the surface of the bank, by a hinged lid, similar to that of some other species of the Mygalides. 5. Descriptions of Three new Species of Marine Shells from the Australian Coast. By J O H N BRAZIER, C.M.Z.S. VOLUTA (AULICA) WISEMANI, n. sp. The shell differs in a great many respects from V. pulchra, Sow. The first three whorls, forming the apex, are minutely granular; fourth, tubercle slightly raised, straight and very sharp-pointed, orange-coloured blotches at the suture; fifth with the tubercles raised, sharp-pointed, tipped with orange, fine orange-coloured blotches at the suture, tubercles white between; basal whorl with five prominent tubercles at the angle, sharp-pointed, tipped with orange, be- |
