The sylvan powers

Obey our summons ; from their deepest dells

The Dryads come, and throw their garlands wild

And odorous branches at our feet ; the Nymphs

That press with nimble step the mountain-thyme

And purple heath-flower come not empty-handed,

But scatter round ten thousand forms minute

Of velvet moss or lichen, torn from rock

Or rifted oak or cavern deep : the Naiads too

Quit their loved native stream, from whose smooth face

They crop the lily, and each sedge and rush

That drinks the rippling tide: the frozen poles,

Where peril waits the bold adventurer's tread,

The burning sands of Borneo and Cayenne,

All, all to us unlock their secret stores

And pay their cheerful tribute.

Differing from the typical form in having rather coarser granulation and the second row of granules below the suture are conspicuously larger. In one example the two adjacent series of granules at the periphery, which wind u[) the spire, are conspicuously spotted with ])ink, and large blotches of a dark olive-green upon the middle of the whorls at intervals occur under one another, thus forming three interrupted stripes which descend from the apex to the angle of the body- whorl. The granules upon the base are small, closely packed, and mo.stly white with pink dots between them. Another variety is almost entirely yellow, but some obscure white spots occur upon the periphery and the lower surface.

On comparing this species with A. modestum of Keeve, with which it has been united, there seem to be sutlicient diftcrences to warrant tlicir separation. The sculpture on the base of the last whorl is much finer in A. modvsium, and the groove in the umbilical region of A. yiryijllus is absent in the Japanese form. There are also dift'erences of colour.

Ratlicr solid for so small a shell. The slight constriction at the upper part of the body-whorl forms a solid crest above it. The apical perforation is very small and deep indeed, narrower than the umbilicus, A very thin callus spreads over the whorl, uniting the columella and the upper end of the labrum.

This species is rather like C. canaliculatus, Quoy & Gaim., but ditlers iu the central areas being more finely lirate, punctate between the linCj and the scales on the girdle are much finer. The valves are dirty white, here and there stained and dotted with light olive-brown, with a few darker dots ou the posterior edge of the anterior and central valves.

Very like A', dor salts, but the valves arc more equally divided dt)wn the middle by the central groove, so that the anterifir and posterior portions are about equal. In A'. do7'- Sd/is they are decidedly unequal, the posterior side being conspicuously larger. This is clearly seen within the valves, being indicated by the position of the strengthening rib.

The sculpture on the anterior areas and the protoplaxcs are similar in both forms. I am inclined to think that the latter will be found to be somewhat variable in form.

Very similar to E. elcyautissima, Dall, from the Antilles, and V. pacijira, Dall, fioin the Hawaiian Islands. Arc they sufficiently distinct to be regarded as diffei'cnt species, or are they not merely variations of one widely distributed form ?

It is curious to note that tlie localities of the three species lie between 11° and 24" north of the equator, at depths ranging from 1S8 to 7oG fathoms, with a bottom-temperature of 3S°, 40'"", and 55°.

The size and number of the granules rcFcrrcd to by Dr. Dall* as distinguishing this species from E. eburnea are variable, for in one specimen from the Andamans they are quite as fine and as numerous as in one example of E. pacifca in the Museum collection.

A SMALL series of reptiles brought liome from the Congo by Drs. Dutton, Christy, and Todd, of the Liverpool School of Tropical Medicine Expedition, contains examples of two poisonous snakes which are new to science and of which I have great pleasure in giving descriptions. The specimens, which have been presented to the Britisli Museum, were obtained near Leo[ioldville.
