PREFACE.
Since the publication of my Catalogue of Australian Land Shells in 1864, numerous new species have been added to the Australian Fauna described by Pfeiffer, Morelet, Adams, Angas, myself, and other authors, many of the typical species of which are in the collection of the Aus- tralian Museum, in my own, and other private collections in the Colony. To enable Conchologists to correctly dis- tinguish the newly described species, and to prevent an accumulation of synonyms, I have undertaken to give a synopsis in this Monograph of all known Australian Land Shells, with their full descriptions ; figuring as far as lies in my power all well-defined species in XVIII plates. I hope soon to be in a position to supplement these, as several new and valuable specimens have very recently been added to my collection.
For the habitats given, I am much indebted to my late friend, Mr. John MacGillivrat, Mr. Masters, the Eev. E. L. King, Mr. F. A. Blackman, Mr. Blomfield, Captain Edwards, and other friends on whose authority the strictest reliance can be placed.
The Illustrations, kindly executed for me by Miss Scott and Mrs. Edward Forde, speak for themselves, and I have no doubt will be duly appreciated by the public.

Class II.— GASTEBOPODA. Order II.— PULMONIFEBA. Section A.— INOPEECULATA. Section B.— OPEECULATA.
Section A.— INOPEECULATA. Family.— HELICID^].
Shell external, usually well developed and capable of containing the entire animal ; aperture closed by an epi- phragni during hybernation.
Animal hermaphrodite, having a short well developed retractile head, with four cylindrical, retractile tentacles, the upper pair longest, and bearing eye-specks at their summits, the lower occasionally wanting [Section Vertigo). Body spiral, distinct from the foot ; respiratory orifice near the base of the right ocular tentacle, small and valve-like ; mouth armed with a horny, dentated, crescent-shaped upper mandible; lingual membrane oblong, central teeth incon- spicuous, laterals numerous, similar.
Genus
HELIX. — Linnjeus.
Shell umbilicated, perforate, or imperforate, discoidal, globosely-depressed or conoidal ; aperture transverse, ob- lique, lunar or roundish ; peristome patulous or reflected, margins distinct, remote, or united by callus.
Animal with a long foot, pointed behind ; lingual teeth usually in straight rows, edge teeth dentated.

Helix Kreffti. Cox, Catalogue of Australian Land Shells, 1864, p. 21.
Shell perforated, orbicular, depressed, thin, pellucid, smooth, with microscopic strife, very glossy, reddish -yellow ; spire broadly convex ; whorls 5, slightly convex, suture slightly margined, last rounded at the periphery, less convex at the base ; under surface flesh coloured and opaque' about the very minute umbilicus ; aperture diagonal, lunate, slightly pearly within ; peristome simple, thin, straight, the columellar margin rather sloping, thickened above, with a callus inwardly, and very slightly reflected outwardly.
Diameter, greatest 0-50 ; least 0-50 ; height 0-25 of an inch.

I cannot venture to keep the shell formerly named by me R. Kreffti distinct from H. villaris of Pfeifler, whose description is quite satis- factory; while that of Eeeve is less so. A remarkably polished, shining, oily-looking shell of a rich honey colour, with the columella white and callous within.

Shell minutely perforated, depress^ -convex, thin, smooth, rather glossy, very faintly striated, pale horny ; spire very short, obtusely conical, suture shallow, slightly margined ; whorls 5, regularly in- creasing, rather flattened, last convex, slightly flattened above, not continued in front ; aperture diagonal, lunate ; peristome simple, acute, regular, columellar margin slightly expanded, and reflected above.

I have taken the description from five specimens presented to the Australian Museum by the original collector, and from the precise locality whence Forbe's specimens were derived. They are much duller than specimens from other places, which those in the Cumin- gian collection, described by Pfeifler and Eeeve, undoubtedly were, as they are usually more glossy, and varying in colour — being white and crystalline, pale, yellowish horny, or of a reddish tint. The
AUSTRALIAN LAND SHELLS. 3
South Australian specimens from Minder's Range, determined by Angas to be of this species, present certain differences, being of a duller aspect, more coarsely marked, and depressed. My specimens from Rapid Bay are normal.
3. Helix circumcincta. Cox. Plate V. Fig. 6 a. natural size, 6 b. magnified. M.C. Helix marmorata. Cox, Catalogue of Australian Land Shells, 1864, p. 20.
Shell minutely perforated, depressly and roundly-convex, thin, very smooth and shining, with microscopic spiral and transverse lines along the suture and centre of last whorl, reddish-horny, pale about the umbilicus ; spire widely and flatly conical, very obtuse ; suture obscurely margined ; whorls 5, gradually increasing, the last rounded ; aperture diagonal, broadly lunate ; peristome simple, thin, the columellar margin very slightly reflected above, and sometimes partially concealing the umbilicus.
Diameter, greatest 0*40; least 0*35 ; height 0'15 of an inch.
Habitat. Kiama. — Masters. Along the shaded banks of the Nepean River, New South "Wales. — Co.r.
As my former name marmorata, applicable to the animal, was found to have been in previous use, it is necessary to change it. Closely allied to the preceding, of which it would seem to be the southern representative. In one or two of my specimens there is even shown a tendency to opacity round the umbilicus, and to the white callosity of the upper part of the columella. The pale band seems to be con- stant. Specimens of this shell sent to Cuming for comparison were returned with the name H. misella, Per. — an imperforate species, with the last whorl carinated, and having an angularly lunate mouth.
4. Helix Waterhousei. Cox.
Helix sub-angulata, Adams and Angas, Pro. Zool Soc., 1863, p. 521.
Shell orbicularly-conoidal, very thin, pellucid, glassy, pale straw coloured, narrowly umbilicated; whorls flat, very finely concen- trically striated, last somewhat angular at the periphery ; aperture very oblique, lunately oval, broader than long ; lip acute, shortly reflected, scarcely covering the umbilicus.
Length ^ line ; breadth 3 lines.
Habitat. South Australia, under stones and logs. — Angas.
A small species, somewhat resembling LT. rustica, Pfr., but with the last whorl sub-angular at the periphery, and with a narrow um- bilicus which is nearly concealed by a short reflexion of the colu- mellar margin.
The description is entirely taken from the work quoted above. The specific name given by Adams and Angas had, however, been applied in 1854, by Pfeiffer, to a Tasmanian species. A new name is there- fore necessary.

Shell perforated, depressly-turbinate, thin and transparent, very smooth, shewing under the lens very faint curved Hues, and traces of still fainter spiral Hues, shining, pinkish or flesh coloured; spire broadly conical, rather acute ; whorls 6, flatly convex, last not descending in front, the periphery shewing nearly obsolete traces of a keel, below convex, glossy, generally opaquely milky-white about the umbilicus, which is minute and shallow ; aperture diagonal, somewhat squarely-lunar, pearly within; peristome simple, acute, columellar margin very slightly triangularly dilated and reflected above. In old age, white and callous.
Diameter 0-65 ; height 0'55 of an inch.

The smoothness, want of carina, pinkish colour, and callous columella are the chief points of distinction between this and BZ. Moretonensis and DT. subrugata.

After comparing a large number of specimens, I have satisfied myself

that this is the shell described by Pfeiffer as H. subrugata, although his description is too brief to ensure absolute certainty.

11. Helix Maconelli. Reeve. Plate III. Fig. 5. M.O.
Bulimus Maconelli. Reeve, Pro. Zool. Soc., 1851, p. 198. Moll PI. XII.
Shell imperforate, ovate, thin, finely striated, the striae decussated by very faint corrugated wavy lines, covered with a reddish chestnut epidermis, with numerous (4 to 8), spiral, interrupted dark bands of various width, consisting of separate rectangular blotches, with series of larger and darker markings near the suture, with yellow or paler interstices ; spire short, obtuse ; whorls 4, moderately convex, very rapidly increasing, last inflated and produced in front in the direction of the axis ; aperture oblique, lunately oval, bluish- grey, and pearly within ; peristome simple, acute, margins joined by a very thin callus, right rather straightly curved, basal regularly arcuated, columellar nearly straight, whitely callous, flatly reflected and adnate.
Diameter, greatest 3-20 ; least 2 20 ; height 2-10 of an inch.
Habitat. Brisbane, Queensland. — Maconell.
This has generally been regarded as a Bulimus ; it is, however, so remarkably allied to Hdix Falconari, that it seems more natural that they should be generically associated. The markings and even the minute sculpturing may be said to be identical, but the present species is more lengthened or Bulimoid, and is imperforate.

Never having seen this shell, of which I cannot help suspecting that the locality assigned is wrong, I have given Pfeiffer' s description of it from the British Museum specimen, and apparently also that figured by Peeve, who remarks — "An obtusely depressed, shining, horny species, streaked and tinted with burnt red." In Gray's original account, it is stated to resemble H. nitida in form, but to be imperforate. His measurements are — axis 3 lines ; diameter Z\ lines.

In the above there is frequently present a spiral reddish thread below the suture. Careful comparison with specimens of the European H. ceVaria shew in that species greater flatness of spire and of the shell generally, and there is a decided difference in the shade of colour. H.

Habitat. Greystanes, Prospect, near Parramatta, N. S. W. — Cox.
Easily distinguished from W. cochlidium by difference in colour, and the fineness of the minute ribs, which are also very much more numerous than in its white plicately-ribbed ally. The name is in- tended to apply to the neat combed-out appearance of the little ribs.
32. Helix Murrayana. Pfr.
Pfr., Pro. Zool Soc, 1863, p. 527.
Shell umbilicated, depressed, rather thin, very closely covered with thread-like folds, scarcely shining, brown ; spire flat ; whorls 5, rather convex, regularly increasing, last rounded, not descending ; umbilicus equalling about ^ of the diameter ; apertiu'e slightly oblique, roundly-lunate ; peristome simple, straight, margins con- verging, columella scarcely dilated near the umbilicus.

Habitat. Cook's Eiver, Sydney, N. S. W., under stones in dry places. — Brazier.
Allied to DT. saturni and H. lirata. Its ash-grey colours and streaks resemble the commonest forms of H. sericatula, and the enor- mous proportional width of the umbilicus is very distinctive. The markings, although somewhat difficult to describe clearly, are characteristic.

Not having seen a specimen of this shell, the above description has been taken from Pfeiffer's Mon. Hel. Viv., Vol. IV., p. 89. Benson states that it is "near H. iuloidea." Peeve, "on examination," declares it to be operculated, and to be a Cyclostoma ; an opinion which Pfeiffer states is evidently erroneous.

Habitat. Port Molle, North Australia. — llacGillivray. Clarence River, &c. — Cox.
Although varying in size and colour — for I have received not only very pale, but even pure white varieties from the Clarence River — also in the degree of excavation of the spire, it is a shell of very easy recognition.

This well marked species, discoid, shining, and curiously radiated with reddish-chestnut, was originally described as being from New Zea- land, and a large variety, yellow, ornamented along the suture with a broad, jointed, chestnut band, as occurring in the Solomon Islands. My Australian specimens agree perfectly with Pfeiffer's description in his Jlon. llel. Viv., Vol. III., p. 633, and also with specimens from the New Hebrides.

Pfeiffer, in Mon. Hel. Viv., Vol. IV., p. 94, says, the Helix coma of Gray is a "New Zealand species, and that it is even found in Van Piemen's Land." A reference to the description of H coma, in Vol. III., p. 99 of the same work, indicates a very strong probability that my Helix Diemenensis is the same. This, however, is only noted now as a point to be attended to in due time,

being broader, sub-depressed, almost smooth, and the umbilicus of the same colour as the rest of the shell, instead of being chestnut, surrounded by a yellow band. A variety, of which I have numerous specimens from the Richmond River, differs in being duller above, in the greater completeness of the ribs which are scarcely fainter towards the mouth, and in the entire absence of the spiral lines occasionally met with in this fine species.

Specimens of a shell from Garden Island, Port Jackson, in my col- lection, so thoroughly agree with the description of Ferrusac of IT. capillacea, copied in Pfeiffer's Hon. LTel. Yiv., Vol. I., p. 90, and as perfectly with the three figures in the original plate, with which I have carefully compared them, that I have not the slightest hesi- tation in referring them to that species originally stated as from Port Jackson. And as this is merely one of the forms of a very variable species, long afterwards named H. Strangei by Pfeiffer, the latter name should be regarded as a synonym. However, to com- promise the matter, I here beg to include under the head DT.
26 AUSTRALIAN L.VXD SHELLS.
capillacea all those shells of the Port Jackson type, with the spire flat, or nearly so, and for the group, much depressed, and finely and closely ribbed, without any decussating spiral lines. I possess a large specimen from the shores of Port Jackson, l-00 by 0-85 of an inch, veiy rudely sculptured, and from the prominence of the lines of growth evidently an old shell, in which there are no spiral lines, and where the spire is quite flat.

Habitat. Brisbane Water. Lane Cove. Penrith. Also Clarence, Rich- mond, and other rivers, as far north as Port Denison. — Cox.
This species is subject to considerable variation. The spiral decus- sating lines are sometimes absent, thus indicating a passage to H. capillacea ; but these specimens are not so depressed, nor is the spire so flat ; usually the shell looks as if varnished, and the rib-like stripe, except towards the apex, are never so prominent as in H. capillacea ; indeed, the last are occasionally almost obsolete, as in a specimen from Ash Island, Hunter Eiver. Examples from the brushes often exhibit, especially on the under surface, a fine deep chestnut hue, and in such situations this shell attains to its greatest dimensions. The measurements, however, are not those of one of the largest size.

Habitat. Clarence and Richmond Rivers. — MacGillivray.
As I have reason to suspect the shell I formerly named H. assimilans to be that previously described as H. bullacea, of Pfr., I have here placed them under one description, but with much uncertainty. My specimens agree sufficiently well with Pfeiffer's descrip- tion, Hon. Eel. Vie, Vol IV., p. 92 ; but when I compare them with Reeve's figure, to which Pfeiffer refers, I see that this does not agree, being prominently striped, with the letter press, which gives the colour as ash-horny, treats of spiral strire, and whorls obsoletely-roundly-keeled at the periphery. Consequently, this second reference, instead of being of assistance, tends only to confound the matter, for both refer to the Cumingian cabinet for the type specimen.

This must be closely allied to II. capiUacea, and H. strangei. The original description is given verbatim, as I have not seen an authentic specimen, nor has Pfeirfer. It appears to me that the word ■•concentrically" is a mistake for " radiately ;" the fact of "spiral" or concentric stria) having been subsequently mentioned indicates this.

This fine species presented to me by my friend, Mr. Walker Scott, much resembles 77. strangei and other allied species in general aspect, but is at once distinguished from it by the absence of any sculpture on the upper surface, by the smallness of the umbilicus, and by the dark outer surface of the peristome.

Subsecpiently, in 1859, he mentions in Sup- plement IV. of same work, that his previous description of this species was taken from an impei-fect specimen. In its adult state, he states that, "it is extremely like H. Jervlsensis ; its greatest diameter, 22; least 18; height 13^ mill. The right margin of the peristome is some- what expanded ; the columella of a violet tint, and reflected over the umbilicus. It differs from H. Jervlsensis in being a more solid shell, by the more gradual increase of the whorls, and by the less inflation of the last."

The locality of the specimen in the Cumingian collection, described by Pfeili'er and figured by Peeve, who copies the original description, was doubtful, but in Vol. IV., p. 167, of lion. ITel. Via., it is stated thet there is a variety, of a dirty yellow colour, from Western Aus- tralia. My description is taken from specimens from Kiama and the Clarence Piver Heads, representing the type. But this species varies considerably, inosculating even with II. Grayi, A remarkable variety of great size from Kiama, chestnut below and yellowish above, with white lip., is figured in PI. VIII., Fig. 10. A pink lip is usual among those from Merimbula, Kiama, and especially the Nulla Mountain, and the size is smaller than in the type. At Ash Island a rather small stout variety is found, chestnut, with pinkish lip ; this inosculates with a variety of LT. Grayi. The last variety to be mentioned, figured PL X., Fig. 5, very dark, granulated and ribbed as usual, with pink lip and livid mouth, does not present any tangible specific difference from the preceding. It is from Ulladulla, collected by Mr. Masters. Although of small dimensions, 0-90. 0"75. (K50 of an inch, the lip is fully formed, the umbilicus perfectly closed, and a thin callous deposit extends between the margin.

At times, after rain, this species is very abundant, otherwise it is not to be found except by digging deeply about the roots of shrubs where it buries itself, and remains for months. There are two very distinct varieties of it — one of a reddish-brown colour, the other of a pale olive-green. This species has for years given me much trouble in determining several of the species of the Australian Land Shells ; for a time I considered it as a variety of II. Grayi, but, although extremely like varieties of that species, where no red blotch is found
AUSTKALIAN LAND SHELLS. 39
round the umbilicus, or following the course of the suture, it is a muck thinner, lighter, and less solid shell ; but the two species are easily distinguished by the animal, on which more stress should be laid in the determination of species. In hopes of having the species determined, I forwarded to the late Mr. Hugh Cuming, to whom I am indebted for many similar acts of kindness, a number of speci- mens ; the greater number of them were returned to me, labelled H. monaoha of Pfr., and the others H. corneo-virens ; but they do not agree with the descriptions of those species as given by Pfeiffer. A number of specimens of a shell lately added to the Australian Museum from Eastern Creek, about 20 miles from Mulgoa, by Mr. Masters, so thoroughly agree with the general characters I have given of this species, except, that they have the colouring round the umbilicus, and following the line of suture as in H. Gragi, which makes it very doubtful to which species these specimens should be refeiTed.

Pive specimens from the second locality agree so well with Pfeiffer's description, that I do not hesitate to consider them as identical, although I can see none of the "minute granulations under the lens," and no mention is made of the shell being radiately ribbed or marked, as indeed nearly all Australian DTelices are.

A more ponderous shell than the preceding, which seems peculiar to N.W. Australia, while the present ranges along the whole of the N.E. coast. It is also distinguished by having transverse striae, and being quite imperforate. I have a very remarkable variety of this species from Miriam Vale, Port Curtis, it is very thin, greenish-olive, and of very small size ; a small mature specimen, the margins of the mouth of which are joined by a callus, measuring not more than 0*95, 0-80, and 0 60 of an inch.

Reeve remarks of this species, that it is a light globose shell, encircled round the middle and upper part with three or four delicately painted brownish-red bands. Its closest affinity is with U. oitceniata of South Australia.

Although subject to considerable variation in size, distinctness of the bands, and in other respects, this shell does not merge into anjr other species. It should come next to H. Grayi, but it is always a more depressed shell. The largest specimens in my collection are from the Howick Isles, including a beautiful albino variety, which might be mistaken for H. Dunlciensis, and the smallest from the Percy Isles, in which last, the depressed form, the granulated surface, the bands and the columellar spot are perfectly distinct.

The preceding description has been taken from two specimens in the Australian Museum, collected by the late Mr. MacGillivray, who in- formd me that much of the pink or rosy hue had faded during the last sixteen years. Eeeve's figure represents this shell, but Ferussac's two most assuredly do not. It agrees with Pfeiffer' a description of H. pelodes, which he himself has finally merged into H. prunum. A shell sent to me by the late Mr. Cuming as " II. prunum, Port Essington," and figured PI. IV., Fig. 4, appears to be H. argillacea, Fer., from Timor, where it is abundant. I have never known a specimen of E. argillacea yet found on the Australian continent.

The only two specimens T have seen, are in the collection of the Aus- tralian Museum, and have a striking resemblance in form to Dermatocera vitrea. It may also in some manner be looked upon as connecting such shells as H. pachystyloides and DT. aridorum.

Peeve remarks that it is a semi-transparent white shell, having a tooth-like callosity within the aperture, and no correspond- ing indentation without. As this forms one of a small and very natural group of shells, the rest of which are known to be "West Indian, it seems probable that its true habitat will prove to be some locality nearer Hayti than Australia.

Habitat. Widely distributed, from South Australia and Victoria, through New South Wales and Queensland to Cape York ; and the Islands in Torres Strait.
From so extensive a geographical range this species might be expected to vary much. Those described are of the largest size, from the Clarence .River. But the shell is usually smaller, very thin, shewing under the lens little of any wrinkling of the surface, and having the spire either flat or even submersed. A pretty smooth variety from Cape York has the spire as acute as in those described. In large speci- mens the pili almost entirely disappear. Those I have from Vic- toria are unusually dark in colour.

This shell bears much general resemblance to specimens of H. mansueta, from the Pine Mountain, Lis more, which are darker than Queens- land specimens ; but the presence of pili, the white lip, the narrower and more covered umbilicus, are very distinctive characters in H. Porteri, which is besides closely allied to the more diminutive H. brevipila, and occupies a place between it and H. mansueta.

A very variable species ; an examination of a series collected by Mr. Masters shows the ground colour to range from pale reddish-horny to very dark reddish-chestnut, the band is seldom very well defined, is often very indistinct, and occasionally wanting ; and the yellow patch on the base may be indistinct or absent. Two specimens from Flinders Island are of a smaller variety ; but there can ba no doubt as to specific identity, for one shows very plainly, not merely, in addition to similarity of sculpturing, &c, the pale patch on the lower surface, but also the spiral band below the suture.

This singular, smooth, white, porcellaneous shell, without any coloured markings whatever, corresponds exactly with the origi- nal description and figures by Pfeiffer, quoted above. The colour was stated to be "whitish?" It is probable that it was a very old shell, from its extensive deposit of callous matter. Subsequently, in the Journ. de Conchyl., 1863, p. 275, M. Crosse remarks that an examination of two living specimens shows that the diagnosis should be modified, the individual figured having lost all its

Iii this lie is mistaken — the coloration lie gives agrees very well with that of an extensive series of specimens in nvv possession of the next species ; hut not one of those coloured ones has the outer lip more than very faintly thickened and reflected, as stated by Angas, Pro. Zool. Soc, 1863, p. 520, to bo the case with his — nor have any of those, upwards of 100 in number, collected lately by Mr. Masters. "While not desirous to add to the number of doubtful species, I can- not admit that the thin, brightly banded, conspicuously striately ribbed specimens to be next described, as specifically identical with this massive, smooth, porcellaneous, granular, white shell already dis- tinguished, and I therefore make it a new species. Pfeiffer's original is stated by him to be from the neighbourhood of Lake Torrens, in 29° S. latitude. Angas gives " under salt bushes, on the plains at Arrowie, near Lake Torrens."

Enough has already been stated regarding the specific distinctness of this shell and H. Angasiana. The name indicates the chief, perhaps the only, character by which it may readily be known from H. leptogramma, and yet occasionally the bands are nearly obsolete.

Mr. Angas, from whose description the preceding has been taken, further says that "this remarkably compact and globose species, of which only two specimens have hitherto been found, is c' aracterised by the rugose strife of the whorls, and by its conoidal spire."

Angas remarks of this, that it is the largest S. Australian land shell yet discovered, of a yellowish-horn colour, banded with orange- brown. The preceding description has been taken from a series of beautiful specimens collected on Flinder's Eange by Mr. Masters, not one of which agrees precisely with the figure and description of Crosse, probably taken from a single specimen. His shell is very much more globose, and it is described as imperforate, while in none that I have seen has the umbilicus been covered over.

Of this very remarkable shell the preceding description applies to what may be considered as the type, but it is extremely variable. In size, my largest specimen measures 2-80, and my smallest (adult) 1*90 inches, in greatest diameter. The lip may be altogether white, Fig. 5, or purplish-black, Fig. 5 a., or in fact of various tints between white and purplish-blaek. Some enormous specimens from Port Curtis are of a green colour as the prevailing hue, Fig 5, and then have the lip very greatly thickened and reflected, with a copious callous deposit between the margins. A series of specimens of a small variety from Pockhampton, shew below a similar appearance to that in the description, but above, the bauds, mostly narrow, are very numerous and decided.

The description applies to the most prevalent form of the shell as figured. It is, however, subject to considerable variation. In some localities it becomes much larger and more solid than usual, when it corresponds with the description of Pfeiffer, iron. Hel. Yiv., Vol. I., p. 329, and resembles the figures of Peeve, who also gives a variety of uniform fulvous-brown, without bands. There is another curious one, which Pfeiffer calls var p., and of which I possess speci- mens, chestnut, with the bands indistinct, and the last whorl yellow at the base. Plate XVIII. , Pig 1, represents a large thin variety numerously and finely banded, from Wide Bay. In fact, among its variations there are some so closely connecting it with H. Lessoni as to render it difficult to separate them. On the other hand, its affinities with H. Yulei are very obvious.

It has, however, equally close affinities with PL. Lessoni, evident only after examination of a large series of specimens.

This species, unquestionably a modified H. bipartita, is so vari- able that a dozen well marked varieties might easily be selected from among the hundreds of specimens now before me. I have taken the preceding description from a Lizard Island specimen. On the peak of that island, the late Mr. MacGillivray found very large and thin specimens under stones, and on the lower grounds, in the scrubs, about the roots of trees, and among dead leaves, a smaller, stouter, and brightly coloured but variable form was abundant; while

on a mound-like rocky islet, distant from tlie shore a couple of hundred yards, a small, dull, solid variety, not exceeding- an inch in diameter, but undeniably specifically identical, was met with. A pale band round the periphery is very often present, and marks the division between the upper light and the lower dark portions of the shell. Yet this may be wanting, there being no line of demarcation, the whole surface being yellowish-white. And as a contrast to these last, some specimens are throughout of a dark-chestnut. The differ- ence in size is very great ; my smallest specimen, fully formed, is less than an inch in diameter. H. funiculata, described elsewhere, I would refer to this head without hesitation ; a specimen before ine, picked out from a number collected on Stephen's Island, agrees with the descriptions of Pfeiffer and Reeve, and the figure of the latter ; it is of a fulvous chestnut colour, encircled with a single pale zone.

I have adopted Pfeift'er's description, Mon. Hel. J'iv , Vol. III., p. 224, as ReeA-e has done, because it has been taken from the typical specimen clesmbed by Forbes. My own, from Port Denison, are paler than in Reeve's figure, but still have a decided fulvous tinge in some cases ; the number of dark chestnut spiral lines and bands varies from 4 to 8. The black lip and umbilical patch afford dis- tinctive characters between this and //. Incei, to which it is most intimately allied.

A very remarkable shell, in form and solidity approaching II. Blom- jieldi, and in colour and markings II. Incei. In short the wonderful parallelism of these shells is so obvious that it may be set down as II. cerata is to H. Incei, so is H. Blomfieldi to 27. Lessoni. The ground colour is white ; the epidermis is remarkably thin. The shell has a waxy and smooth, rather glossy appearance, especially below.

In the last mentioned locality, where Mrs. Forde first observed it as a novelty, it occurred in Mr. Guilfcyle's nursery, and was doubtless an importation among soil with plants. With reference to the locality on the Frankland Isles, the late Professor E. Forbes suggested that it might have been carried thither by floating timber, which is ex- tremely probable. It is pre-eminently a wanderer, as will be seen by the list of places, widely separated, where it has been found : — Cuba, Brazil, Reunion, Mauritius, Natal, Java, Bengal, China, Sandwich Islands.

Perhaps the descriptions of Pfeiffer and Reeve, which frequently dis- agree, were taken from a single specimen. None of mine shew any angularity on the periphery as stated by them, but not shown on Reeve's figure, nor are there either pale or dark markings about the umbilicus, as mentioned by these writers. All the specimens which I have seen are concolorous, and of a vinous hue.

A variable shell. The preceding description applies to what I consider to be the typical form, with black lip and decided markings. A larger variety, of which one individual measures 2-25 ; 1*75 ; 1*70 of an inch, is scarcely so brightly marked, and has the lip and colu- mella of an obscure violaceous or livid hue. Reeve's figure and Pfeiffer's description, Mon. Hel. Viv., Vol. I., p. 246, apply more particularly to this variety. A very beautiful variety from the Clarence River, smooth and glossy, the sculpture being reduced to its minimum, is of an intense blackish-chestnut, gradually fading into pale reddish-chestnut at the apex. Another variety, although dark and unhanded below, has the spire pale, and finely spirally lined ; and there are several others.

We see here how, in two groups, or sections of the great genus Helix, one in each beautifully represents the other.

Several mistakes regarding identity and locality between this and II. Gdertneriana have been made by Pfeiffer, Forbes, Reeve, and myself. This shell, I am enabled to state with certainty, is not from Port Essington as originally stated. It was first found in the locality indicated by me during the voyage of the Beagle, and subsequently during that of the Rattlesnake, and since then it has twice been col- lected there for me in abundance. It is curious that this fine shell should apparently be completely confined to one little island, the dry portion of which is not more than a quarter of a mile in length.

This seems a fit place to mention, as this description is some- what at variance with Pfeiffer's, that the number of whorls, one less than he makes it, is counted from a front view, and as is also the proportion between the last whorl and the rest of the shell, which is simply the relation of the mouth. He gives no directions on these points, as he does regarding measurements.

In my collection there are two specimens of a shell from Mr. Cuming, marked li B. rhodostoma," Western Australia. As these agree with the original description of B. indutus of Menke, and that of Pfeiffer, Mon. Hel. Viv., I have made out the above description by collating from all three sources. At the same time it appears to me highly probable that the two are specifically identical ; the markings, and colour of the mouth within, are not good points of difference, unless confirmed by others, and Gray's name has the priority.

AUSTRALIAN LAND SHELLS. 75
This species, which far exceeds B. Kingi in diversity of markings, con- spicuously differs from it in the first instance by its greater solidity and less lengthened form. Meuke, Moll. Nov. Moll. Spec, p. 7, 1843, specifies four varieties. Pfeiffer gives descriptions of six, Mon. Hel. Vtv., Vol. IV., p. 477 ; and my own collection could furnish others. Yet a few are pretty constant in their characters. The description given above applies to what is perhaps the most usual, the pale cokmred type. These pale shells have almost a porcellaneous ap- pearance ; they may be entirely unmarked, have a sutural band of reddish-chestnut, with or without longitudinal streaks of the same, pale and indistinct, or numerous and deeply coloured, &c. ; the mouth within is white, or shewing a pinkish hue, and there is very frequently a fleshy tint on the columella and about the umbilicus.
Of the dark series, the most remarkable, which includes my largest specimens, are very closely and narrowly longitudinally streaked, with white, chestnut, or reddish-brown, &c. The interior of the mouth is purplish, darker in proportion to the colour of the shell. In old specimens the columella is very much thickened and callous above, but the umbilicus is never completely closed. This last is Pfeiffer's var. S., and is represented by Peeve, sp. 243. A much smaller dark variety, nearly black, with a reddish apex, and very finely longitu- dinally streaked with white threads, has a single reddish spiral band, and the mouth is black within.
A variety found along with the preceding by Mr. Masters, on an island in King George's Sound, has a very pale chestnut ground, a reddish apex, a dark spiral band under the suture, and is handsomely streaked with dark chestnut and threads of white. Lastly, there is one prominently streaked blackish and reddish, which has three markings, interrupted by light spiral bands.

A great deal of confusion has been unnecessarily created with reference to B. Kingi in its relationship to B. trilineatus. Nearly twenty 3'ears ago Pfeifler, Man. Hel. Viv., Vol. II., p. 174, observed that B. trilineatus seemed to be a variety of B. Kingi. It would have been better perhaps had he acted upon this opinion, which might have saved three out of the four figures, with descriptions in Peeve, which are calculated to confound. Let the reader carefully compare the plates and descriptions of sp. 310, and sp. 397, and he will see a good example of attempted conchological mystification, without any excuse on the score of difficulty.
Having examined many hundred specimens of Bulimi other than B. melo, collected at King George's Sound by Mr. Masters, I feel no hesitation whatever in referring them to one species. Those corres- ponding with Gray's original description of B. Kingi, as being conically-ovate, with aperture equal to the spire and being inside the mouth of a purplish black, are easily picked out ; but there exist gradations between such and the ovately- conical shape, with spire longer than the last whorl of Quoy and Gaimard' 's original descrip- tion of B. trilineatus, I therefore join them. My description applies to shells exhibiting the most usual style of marking, including the short Kingi and the long trilineata, marked precisely alike, and in shape graduating as one series. Among the varieties one is whitish with very faint }'ellowish streaks ; this has the mouth white within. Another pale variety, with more frequent, but very narrow dark streaks, has the darkened mouth and dark columella patch of the description. This is always a much thinner shell than B. melo, more elongated, and not inflated.
Here I take the liberty of referring to the figure in Wood's Index Testaceologicus, edition by Hanley, 18 ">6 — Helix. Plate VII. Fig. 27 a. — for the purpose of expressing my admiration of the ingenuity displayed in producing a figure so utterly at variance with what it is intended to represent ; yet, the very next figure, that of B. Bufresni, although also on a very small scale, is remarkably good.

This inconspicuous little horny-brown shell I placed provisionally with Bulimus, when describing it three years ago. The curious twisted columella, and the parietal plate, were duly noticed in the original description. They are not compatible with Bulimus. On again taking up the subject, I find that the species under consideration comes within the section Frickella of the genus Achatinella. As all the hitherto recorded species of that genus — 210 in 1859, accord- ing to Pfeiffer's Mon. Hel. Viv., Vol. TV., p. 570 — are peculiar to the Sandwich Islands, it is a matter of extreme interest to find even an aberrant form, previously known by one species only, represented in Australia.

The description applies to specimens from the latter locality, with fully formed mouths; I cannot find that the " three folded columella" of Forbes' original description agrees with mine, unless he has in- tended the plait on the body whorl to be the superior on the colu- mella, and by misprint inferior has been given.

VITRINA.— Draparnaud.
Shell imperforate, very thin, pellucid, hyaline, depressed ; spire short; whorls 2 to 3, rapidly enlarging; aperture large, lunate or rounded, columellar margin slightly in- flected ; peristome thin, often membranous.
Animal elongated, too large for complete retraction into the shell ; mantle produced, transversely rugose, covering the front edge of the last whorl and part of the spire of the shell, and furnished with a posterior lobe on the right side. Mandibles arcuate, rostrate ; lingual teeth (of type, Vitrina Draparnaudz), 100 rows of 75 each; marginal teeth with a single, long, recurved apex. — Thomson.
I may here remark that the animals of all the Australian Vitrince have more the characters of Arion, the tail being longer, more abruptly truncated, the mantle more de- veloped and possessing a caudal gland.

Por the purpose of serving as a starting point, and to determine the identity of this the first mentioned of Australian Succinea, I have copied. Pfeiffer's description, taking the measurements from my own specimens. Perhaps l( acutely" had better be substituted for "acuminately;" I cannot count more than 3 whorls, the number represented in Ferussac's figure.
When Perussac named and described this species, he gave as its habitat " Australian Isles." Quoy and Gaimard afterwards found in Tasmania a Succinea, which the)' also referred to S. Australis, and figured and described it. Of course, neither their descriptions nor figures agree perfectly. Pfeiffer, many years afterwards, having previously in 1848 pointed out the discrepancy between the figures, in 1 8 - j 9 — Jlon. Ilel. Viv., Vol. IV., p. 812 — gives an original description of S. Australis from Tasmanian specimens, with which certain of those in my collection agree. It may be mentioned here, in case it should be supposed that New Caledonia is included in the range of this species, that in the " Faun. Conch , Sfe., de la Nouvelle Caledonia,'''' by M. Granics, the figure given from a New Caledonian specimen is that of another species, as one glance at the left lip will show, while the description is Pfeiffer's, verbatim, from Tasmanian specimens.
In Menke's specimen, " Molluscorum JVovce Hollandice" he records, p. 6, the existence of Succinct' amphibia, of Drap., as occurring under the bark of Eucalypti, in the district of Hay, W.

The first of these is by Pfeiffer looked on as a synonj-rn of S. putris, Lin., and like the latter is believed to be confined to Europe.

AUSTRALIAN LAND SHELLS- 89
Shell ovately acuminate, thin, opaque, slightly shining, longitudinally and irregulaiiy striated, whitish, yellowish, or reddish-horny, with occasional pale streaks ; spire conical, acute, papillary ; whorls 3, convex, last inflated ; the aperture slightly exceeding the spire, scarcely oblique, irregularly and narrowly ovate, enamelled within of general colour of shell ; peristome simple, thin, columella very narrow, whitely callous.
Length 0^45 ; breadth 0'23; aperture 0"25 long ; 0-20 broad, of an inch.
Habitat. Port Lincoln, Point Lowly, Wallaroo, Plinder's Bange, Penola, S. Australia. — Angas, Masters, Woods, fyc.
The above description exhibits the ordinary and average appearance of this shell, which, however, attains to greater dimensions. A large white variety from Wallaroo is remarkable. Mr. Masters informed me that this species, which he found in every place he visited in South Australia, does not confine itself to the ground, but is equally found on trees.
315. Succinea scalarina. Pfr.
Pfr., Pro. Zool. Soc., 1861, p. 28.
Shell ovately-conical, "scalarina," rather solid, irregularly rugosely plicated, slightly shining, reddish ; spire elongated, lather acute ; whorls 3-^, convex, last slightly exceeding the spire, somewhat attenuated at the base ; columella receding, nearly straight, forming with the peristome an indistinct angle ; aperture oblique, oval, scarcely angular above ; peristome simple, columellar margin slightly reflected above.
Diameter, greatest 0'51 ; least 030 ; height 021 of an inch.
Habitat. King George's Sound, W. Australia. — Angas.
The preceding description has been entirely taken from Pfeiffer. It will be seen by the measurements to be one of the largest Austra- lian species. Scalarina may be translated as resembling a staircase — but conchological latin is not always to be found in a dictionary.
216. Succinea strigillata. Adams and Angas. Plate XV. Pig 5, 5 a. enlarged. M.O. Adams and Angas, Pro. Zool. Soc, 1864, p. 38.
Shell ovately conical, thin, semi-pellucid, pale horny yellow ; spire scai'cely equalling the aperture, apex papillary ; whorls 3^-, strongly convex, longitudinally, finely and minutely striated ; aperture oblong ovate, left margin with a long thin callous deposit, right simple.
Length 5 lines ; breadth 1\ lines.
Habitat. Shark's Bay, N. W. Australia. — Angas.
The authors from whom the description has been taken remark that it is somewhat allied to S. strigata, having the same papillary apex, but differing in being smaller, thinner, of a lighter colour, and in the whorls being less strongly rugose.
217. Succinea arborea. Adams and Angas. Adams and Angas, Pro. Zool. Soc, 1863, p. 523.

Not having seen specimens of this small species, I have been obliged to copy the original description. It is stated to be as strictly arbo- real, as S. strigata is terrestrial.
218. Succinea Eucalypti. Cox. Plate XV. Fig. 3, 3 a. en- larged, 3 b. on bark. M.C. Cox, Pro. Zool. Soc., 1864, p.
Shell ovate, thin, shining, translucent, smooth, very faintly and irregu- larly striated, pale reddish-horny ; spire very short, obtuse and papillary at the apex ; whorls 3, convex, last ovate ; aperture about twice the length of the spire, of a nearly regular oval, very slightly oblique, within thinly enamelled and glossy; peristome simple, straight, margins connected by thin callus, columella nearly straight, receding towards the axis.
Length 0-28; breadth 0-17 ; aperture 0-20 long ; 0-10 broad, of an inch.
Habitat. Throughout N. S. W., from the Clyde Eiver on the South, to the Clarence Eiver on the north, New South Wales. Facing- Island, Port Curtis, Queensland. — Cox.
Although this small species is chiefly found under the bark of gum trees, Eucalypti, it is not confined to such situations, but goes out on the branches and leaves of other trees and bushes.

Terrestrial Mollusca breathing air by lungs, and fur- nished with an operculum attached to the foot of the animal, by which it closes the aperture of its spiral shell.
All the animals of this order strongly resemble each other in structure, by which, besides the operculum, they are easily distinguished from the other terrestrial Mollusca (Limacidcv, Helicidce, Oncidiadce, Lymnceidce, Auricididce). The sexes are strictly distinct, never hermaphrodites, as in Helicea, and the animals bear 2 contractile, not retractile, tentacles, at whose posterior or exterior bases the eyes are placed. In some the mantle margin is free, by which character Ferussac distinguished the Helicince from the Turbines ; in others, the mantle is entirely hidden within the shell.

This species is easily recognised by the broad sculptured interstices between the well defined ribs, and by its margined suture.

I cannot find any clue whatever to the work in which this genus was first published by Menke ; in fact my only record of it is a remark by Angas, in Pro. Zool. Soc, 1863, p. 523 ; and the characters above are taken from specimens in my collection. Pfeiffer, in his Supple- ment II., 1865, p. 8, of Pneumonopomorum Viventium, in alluding to this species, doubts to which genus it belongs.

The only specimens of this shell (4) which I have seen are in the Australian Museum. All have a dull, dead, semi-fossil chalky look, yet the brightness of the enamelled mouth shews that they are not " dead shells." Probably the number of whorls will be found to be about 9.

Two specimens which the Rev. R. L. King has obligingly lent me are marked as from the Clarence River, N. S. W. The rimation or sub- stitute for an umbilical opening is, in this species, confined to a slight shallow hollow. A Norfolk Island species, not yet named, approaches more closely to the present than any of the four Lord Howe Islaud Diplornmatina' described by Pfeiffer, although the latter locality is within a day's steaming of New South "Wales, and the former five times as far distant.

The preceding description is copied from the original. Reeve remarks that it is quite of a distinct type. The spiral ridges are not delicate raised lines, but strongly sculptured ridges, with the interstices flatly grooved. Cyclostoma orbiculatum of Benson is regarded by Reeve, who had the great advantage of comparing the original specimens, as being merely a smooth variety, which indeed might almost have been inferred from the descriptions, and I have, there- fore, given that name as a synonym.

Reeve, whose description of this .species I have given above, doubts if this is anything more than a smooth variety of Cyclophorus liricinctus, as he found obvious traces of the spiral grooves and ridges, and next the suture and around the umbilicus they are more decided.

Length 0-37 ; breadth 0-20; aperture 0-10 broad, of an inch.
Habitat. Clarence Biver, New South Wales, under and in decaying logs. — Wilcox. Moreton Bay. — Bidwill.
This highly polished beautiful species is closely allied to P. bilinguis. The truncation of the columellar tongue, which I find constant, is the most notable character.
242. Pupina robusta. Cox. Plate XVI. Pig. 13 natural size, 13 a., 13 b. much magnified. M.C.
Shell oblong-ovate, moderately solid, polished, shining, pellucid, not striated, pale yellowish or reddish-horny ; spire ovately tapering, obtuse, suture thinly enamelled on two lower whorls ; whorls 5 to 6, last in front more than equalling the remainder, penultimate equal to those above ; aperture nearly circular, vertical, produced obliquely outwards ; peristome and auricles white or pale, thickened, expanded, upper channel wide, vertical, bordered by a plate shewing a triangu- lar front, lower channel obliquely cutting the columella much above the centre, and having a small lamella, triangular from in front.
Length 0*33 ; breadth 047 ; aperture 0*10 broad, of an inch.
Habitat. "Warro, Port Curtis, Queensland. — Blachman.
Closely allied to P. bilinguis, but smaller and stouter, lip not continuous, and having the line of axis of the mouth much more oblique, and the lower canal higher upon the columella. A very young specimen,

apparently of this species, is very finely striated under the lens, but I cannot see any strise in full grown specimens.
243. Pupina ventrosa. Dohrn. Plate XVI. Tig. 14 natural size, 14 a., 14b. much magnified. M.C. Dohrn, Pro. Zoo!, Pro., 1862, p. 183.
Shell ovate, rather thin, polished, shining, transparent, smooth, not striated, pale reddish-horny ; spire ovately-conical, slightly obtuse, suture scarcely impressed, and on the two lower usually callous, and sometimes with a very faint streak of red ; whorls 5, three upper- most, slightly convex, lower two continuous, last viewed in front much more than equalling the remainder ; aperture vertical, circular; peristome slightly thickened, scarcely expanded, upper channel oblique, protected by a triangular blunt plate, columellar a little above the centre, with a triangular obtuse auricle, about equalling the other in size.
Length 0-30; breadth 0*17; aperture 0- 10 broad, of an inch.
Habitat. Endeavour River, N. E. Australia. — ■MacGillivray.
This shell is smaller and less elongated than P. bilinguis, and the mouth is less oblique to the axis. Dohrn's locality, " Cape York," is a mistake.
244. Pupina pineticola. Cox. Plate XVI. Fig. 8 natural size, 8 a., 8 b. much magnified. M.C. Cox, Pro. Zool. Soc, 1866, p. 375.
Shell fusiformly ovate or pupiform, rather solid, smooth, shining, in youth very finely striated, the stria; disappearing or becoming obso- lete, glassy white, or pale reddish-horny ; spire suddenly tapering, obtuse, lower suture enamelled ; whorls 5, last viewed in front ex- ceeding half the length of the shell, penultimate equal to last in width, and equalling in length those above it ; aperture circular, slightly oblique ; peristome and auricles white or pale, thickened, upper canal in a line with the apex, lamella showing in front, acute, triangular, inferior canal obliquely cutting the columella near its centre, with a short triangular plate above.
Length 0"22 ; breadth (Ml ; aperture 0*06 broad, of an inch.
Habitat. Pine Mountain, Lismore, Upper Eichmond Eiver, on the ground, burrowing in dry weather. — MacGillivray.
The nearest allied species is P. Pfeifferi ; but this is a larger and stouter shell, having the axis of the mouth more divergent, and very different canals.

thickened, upper canal covered by a large curved triangular tongue, inferior larger at the lower columellar margin, formed above by the large roundly truncate termination of the columella, and below by the lip, both of which margins are prolonged upon the back of the whorl like parallel and somewhat diverging walls.
Length 0-30 ; breadth 0-16 ; aperture 0-06 broad, of an inch.
Habitat. Fitzroy Island, N. E. Coast of Australia. — MacGillivray.
This remarkable species is so unlike any other Australian Pupina that it need never be confounded with them.
246. Pupina Pfeifferi. Dohm. Plate XVI. Fig. 9 natural size, 9 a., 9 b. much magnified. M.C. Dohm, Pro. Zool. Soc, 1862, p. 183.
Shell narrowly ovate, pupiform, smooth, polished, shining, glassy, translucent, white to very pale yellowish or reddish ; spire ovately- conical, obtuse ; whorls 5, suture scarcely impressed, callous, sub- margined, last in front equalling ^ of length ; aperture slightly diagonal, the lower margin being advanced, circular ; peristome white, thickened, very slightly expanded, upper canal viewed in front with an acutely triangular tongue, lower very narrow, obliquely cutting the centre of the columella, and bordered above by a rather broad truncately rounded auricle.
Length 0'22 ; breadth 0*10; aperture 0'05 broad, of an inch.
Habitat. "Eocky Isle," off Cape Flattery. Lizard Island, and Cape York, N. E. Coast of Australia. Darnley Island, Torres Straits. — MacGillivray.
The smallest Australian species, which is said by Dohrn to differ from P. Strangei, to which it is closely allied, in the parietal lamella (acute, entering), the oblique aperture, the callous suture, &c. It may be here mentioned that after examining the opercula of all the previous species of Pupina I found nothing abnormal.
247. Pupina Strangei. Pfr.
Pfeiffer, in Pro. Zool. Soc, 1854, causu omissa? Pfeiffer, in Make. Bl., 1854, p. 90.
Shell pupce-form, very thin, pellucid, very shining, pale horny ; spire swollen, conical towards the top, somewhat acute ; suture not callous ; whorls 5 \, convex, last contracted, scarcely projecting beyond the base of the axis ; aperture sub-circular, bicaniculated ; parietal callus slightly prominent, on both sides ending in a very small acute tooth, separated by the narrow channels from the shortly reflected, somewhat thickened peristome.

248. Callia splendens. JDohm. Plate XVII. Fig. 8 natural size, 8 a., 8 b. much magnified. M.C. Dohrn, Pro. Zool. Soc, 1862, p. 183.
Shell conically-ovate, rather thin, smooth, very glossy, pellucid, pale reddish-horny ; suture impressed, narrowly margined ; whorls 5, gradually increasing, slightly convex, last viewed in front more than equalling j of the length ; aperture vertical, acutely, irregu- larly and slightly obliquely ovate ; peristome thickened, moderately expanded all round, slightly expanded and thickened at the colu- mella.

Habitat. Lizard Island, N. E. Coast of Australia, among dead leaves, &c. — Mac Gillivray.
Br. Dohrn states the operculum to be "normal," by which, I presume, he means similar to that of C. lubria, the only previotxsly known species. Now, in that, both aperture and operculum are circular ; here, they are ovate, and the lid is extremely thin, membraneous, and, under the microscope, exhibits no circular lines of growth whatever.

Closely allied to IT. Dragtonensis. A variable shell in colour ; it fre- quently has a dead and chalky, instead of a porcellaneous, appear- ance, and the red and violet of the spire are sometimes greenish, or bluish, or altogether wanting ; the throat is occasionally reddish or yellowish, instead of white. My Queensland specimens are not generally so brightly coloured as a series from the Eichmond.

Habitat. Drayton Eange, Queensland. — Stutchhury.
Although I have two specimens sent me by Cuming under this name, and they agree with the description, yet I have preferred to give Pfeiffer's account, merely adding the colour of the operculum, which is present in one of the two.

This fine species, as well as the two following, were obtained during Captain Cadell's recent expedition to the N. Coast of Australia, in large numbers, at the locality mentioned. Closely allied to and resembling Helix pomum, but easily distinguished from that species by its black coarsely granular aperture, by the black band which follows the suture, and by its transverse wrinkled sculptured surface.
