PREFACE, TT may cause surprise to some who are not amongst my most * intimate friends, that my name should be attached to a volume on any other branch of Natural History than one which is in some way associated with the Vegetable Kingdom. To these it may be necessary to explain that I have only returned on this oc- casion to an " old love," long deserted for the fascinating charms o% " moulds and mildews." In more youthful days I bird's -nested, caught butterflies, and worried reptiles, with all the pertinacity of youth, and amongst all these pursuits acquired a taste for the study of our native birds, reptiles, and insects, which led to my first lessons in the classificatory sciences. From these, it is true, I diverged in later years, and almost confined myself to plants; but in a VI PKEFACE. foolish moment, perhaps, the old hankering to have a word or two with one's "first love/' has come over me, and resulted in this humble account of " Our Reptiles/' I make no preten- sions to the production of anything more than a popular volume on a rather unpopular subject, to the espousal of the cause of a much-abused and scandalized class ; and if I only aid in recovering their character from a little of the obloquy which attaches to them, I shall not regret the venture. The man of science, if he seeks for that which is novel or abstruse, had better close the book, and go no further. I do not presume to have written anything for him ; but for those who know little or nothing of the subject, I hope that herein may be found a useful introduction, and a trustworthy guide. The order of the chapters is not precisely that of the classification of the animals described, but in the Appendix a Systematic Arrangement has been pursued. In conclusion, I acknowledge with pleasure the kind and courteous assistance rendered to me by Dr. Albert Glinther and Dr. J. E. Gray, of the British Museum, in procuring PREFACE. Vll figures to illustrate the work,, as well as for hints and suggestions in its prosecution. To those who honour it with a perusal, I now commend it with " all its imperfections on its head," M. C. C. UPPER HOLLOWAY. INDIAN SNAKE-CHARMER. (From a Sketch by a Native Artist.) BEPTILES AND SNAKE-STONES. REPTILES, in zoology, constitute a Class of vertebrate animals (that is, animals with a backbone) intermediate between birds and fishes, having a greater affinity with the latter than the former. They are generally described in scientific works as having cold blood, being the possessors of a heart with sometimes one and sometimes two auricles, but with only one ventricle ; so that, at most, there are but three chambers in their hearts instead of four. They are still further characterized as oviparous, breathing by lungs, or partly by lungs and partly by means of gills; thus combining one of the elements of fish-life with those of higher organ- 2 OUR EEPTILES. isms. Finally, their scientific portrait is com- pleted by the announcement that the body is either covered with shelly plates (as in the Tor- toises, &c.), or with scales (as in the Snakes), or with a soft naked skin (as in the Toads and Progs) . This is the orthodox definition of what con- stitutes a Reptile, but not the best definition, nevertheless, as Mr. Edward Newman has shown in some important remarks on the classification of these animals. " The epidermis," he writes, " or outer skin of quadrupeds, is clothed with hair, of birds with feathers, of fishes with scales, but in reptiles it is uncovered, perfectly naked. The processes, whether described as squamce (in Latin), or ecailles (in French), are projections, folds, or rugosities of the under-skin ; and are not deciduous like hairs, feathers, and scales, but are as permanent and durable as the bones themselves. This may be seen when the slough of a snake is found. This slough is continuous, and contains a faithful mould of each of these processes : it is a very beautiful and very instruc- tive object. The tortoise exhibits the pecu- liarity of an articulated skin, the articulation being clearly discernible in the living animal, but becoming more conspicuous after death, when dehiscence takes place and the plates fall off, per- REPTILES AND SNAKE-STONES. 3 fectly detached from each, other."* Let any one examine the cast-off skin, as it is called, of a viper or snake, and he will find it to be a thin delicate cuticle which had covered all the pro- jections and inequalities of the true skin, con- taining a little pouch for each of the ' scales ' (falsely so called) into each of which a projection had extended. True scales are easily rubbed off from the skin in fish, but there is no rubbing them from that of a snake ; they are permanent projections with a scale-like form. If there is any value in words, then ' scale ' cannot be applied at the same time to the deciduous, flat, horny plates of fish, and the flat, depressed, but persistent irregularities of the skin in reptiles. However, with this reservation, we shall pro- ceed to call them ' scales ' in deference to custom, and the collective wisdom of those more learned in reptiles than ourselves. Having endeavoured to satisfy our scientific friends, by taking off our cap to ( authority/ and furnishing a ( red-tape ' description of the class REPTILIA, we may be allowed to digress a little by way of commentary upon the text. We will not suppose it necessary to state that ' Reptile' is derived from the Latin word rej)to., ' I crawl/ nor justify its application to such as * The Zoologist, p. 8450, B 2 4 OUE KEPTILES. do not crawl. Nor shall we deem it advisable to plunge into the controversy concerning the mode of progression with the serpent before it fell a victim to the curse, " upon thy belly shalt thou go, and dust shalt thou eat, all the days of thy life." It would, notwithstanding, be an in- teresting occupation to trace the intimate con- nection between the reptile race and some of the most important religions of the world, therein to seek the hidden and mysterious meaning of which serpents, especially, were but the symbol. This would lead us far, both from our subject and our object, and we will rest con- tent with hinting at a wide field of inquiry. The heart and blood are two important points of difference between reptiles and the higher vertebrate animals. All reptiles are cold- blooded. They possess a heart, it is true ; but, as compared with higher organisms, an imper- fect one, inasmuch as it has but one ventricle : the result of this is that respiration is imper- fect, and as respiration gives heat to the blood, which in turn sustains the heat of the body, it follows necessarily from their organization that the temperature in reptiles should be very low. Let a frog leap upon your hand, or take a newt between your fingers, and the chilly, smooth, apparently slimy appeal to the sense of touch will carry conviction far swifter than argument. EEPTILES AND SNAKE-STONES. 5 In being oviparous, or producing their young from an egg, these creatures agree with birds as well as fishes ; but in some instances the outer covering of the egg, then only a thin membrane, and not a hard shell, is broken at the moment it issues into the world, and the lively young escape, in all respects miniature representatives of their parents. In the latter case the term ' ovo-viviparous ' is generally applied, and in this sense we may, perhaps, have occasion to use it. The features of a double life, wherein one portion is spent in water, breathing by means of gills, and the other on land, respiring with lungs, will be illustrated when treating of toads and frogs and other amphibians, so that it will be unnecessary to enter upon the subject here. The multiform variations in reptile life may well surprise the uninitiated, even perhaps amounting to a doubt whether such things as Tortoises, Alligators, Snakes, Toads, Newts, Lizards, &c., differing so greatly in external ap- pearance, can be regarded by scientific men as members of the same class. Indeed, the last- named gentlemen are not agreed that they shall constitute one class, but a portion are separated, such as toads, frogs, and newts, to constitute another class, to which the name of Amphibia is given. Our readers will not thank us for enter- t> OUR REPTILES. ing upon a long dissertation on the merits of the case, or appreciate any fine-drawn distinc- tions which it might please us to make. Suffice it to say that, although perhaps the majority of Erpetologists (' learned in reptiles ') admit the Amphibians as a distinct order, we shall, in the present instance, adhere to the old method, and regard them all as ' Reptiles/ For the purposes, not only of classification, but of orderly description, these animals are naturally divisible into four groups, — we may call them orders, — of which the first are the Chelo- nians or Tortoises and Turtles, the second the Saurians or Lizards, the third the Ophi- dians or Snakes, and the fourth the Amphibians or Toads, Frogs, and Newts. The first, or Che- lonians, are scarcely represented in Great Britain at all. The few turtles, which have been borne in times past upon the waves that wash our shores, and cast relentlessly upon our coast, had really no business there, and only came as occa- sional, distinguished, and probably involuntary visitors. Under these circumstances we have given them a place at the end of the volume, although, according to rigid science, they should have been at the beginning. The Saurians or Lizards are represented in Britain by four species, three having visible legs, and the fourth snake-like in form. That the REPTILES AND SNAKE- STONES. / Sand Lizard and the Viviparous Lizard, as well as the Slow -worm, are true natives no one will doubt ; but whether the Green Lizard deserves a place in our Fauna is a more open question, and is again referred to hereafter. The great Gavial of the Ganges, sometimes nearly eighteen feet long, the Crocodile of the Nile, the Alligator of North America, and the Caymans of the South, are the giants of this order ; but of these we have, happily, no representative. In neither of the two orders named do any of its members possess poison-bags or venomous fangs, though we hap- pen to know that it is a firmly-rooted opinion in India that there is one or more species of lizard capable of causing death by a wound, rendered mortal either by a virulent saliva, or some other means. Such a lizard, however, is entirely un- known to scientific men, and by them the Bis- cobra is believed to be only a phantom of ' the heat-oppressed brain/ A surgeon, for many years on service in India, tells us that he knew of an instance of a man descending a well being bitten by such a lizard, that he was drawn up and indicated the position of the reptile ; that a second man descended and killed the bis-cobra> which was afterwards preserved in spirits at the barrack -hospital for many years, and, finally, that the man who was bitten died in consequence in a few hours. O OUR REPTILES. The third order includes all the snakes, from the monstrous Boa constrictor and the dreadful Rattlesnake and Cobra to the Ringed Snake and Viper of our own islands. Of these we possess but three, two of which belong to the harmless snakes and the third to the venomous snakes. There are many others known on the Continent of Europe which do not occur on this side the Channel, and in Ireland those of Britain are also unknown. The last group or order contains the Amphi- bians, or those reptiles which at some period of their lives inhabit the water and are truly aquatic, and at another are either wholly or chiefly ter- restrial. There are some very singular creatures in this group, such as the Salamander, to which such romantic stories of its incombustibility be- longed, and of whom it was said, "If a salamander bites you, put on your shroud." As late as 1789 a French consul at Rhodes, hearing a loud cry in his kitchen, rushed to learn the cause, when his cook, in a horrible fright, informed him that he had seen a certain personage, who shall be nameless, in the fire. The consul affirms that he thereupon looked into the bright fire and saw a little animal with open mouth and palpitating throat. He took up the tongs to secure it, but at first it scampered into a corner of the chimney, lost a bit of its tail, then hid amongst some hot REPTILES AND SNAKE-STONES. 9 ashes. It was ultimately secured, found to be a little lizard, was put into spirits, and sent to Buffon. Thus runs the story, of which we must permit our readers to believe in proportion to their credulity. We have now indicated the primary groups which include the seventeen species found either as true natives, or naturalized, or as occasional visitors to the British Isles. Of these, two belong to the Chelonians or Tortoises, four to the Saurians or Lizards, three to the Ophidians or Snakes, and eight to the Amphibians, of which latter, half belong to -the section in which the individuals, when mature, are not possessed of a tail, and half to the section of Amphibians having tails in all the stages of their existence. Only one of the seventeen is capable of inflicting serious injury by means of its venomous fangs, although the toad secretes an acrid fluid beneath its skin, to which allusion will hereafter be made. " Frogs and toads are found on the Shetlands, whilst Viper a berus, the most northern snake, is already scarce in the north of Scotland. Rana temporaries is met with in the Alps, round lakes, near the region of eternal snow, which are nine months covered with ice; whilst Vipera berus reaches only to the height of 5,000 feet in the Alps, and of 7,000 in the Pyrenees. A triton or a frog, being frozen in water, will awake to its 10 OUR REPTILES. former life if the water is gradually thawed; I found myself that even the eggs of Eana tem- poraria, frozen in ice during seven hours, suffered no harm by it, and afterwards were developed. A snake can only endure a much less degree of cold : even in the cold nights of summer it falls into the state of lethargy ; it awakes late in the spring, when some frogs and tritons have already finished their propagation ; it retires early into its recess in harvest, whilst still the evenings resound with the vigorous croaking of the tree-frogs and the bell-like clamour of Alytes obstetricans. Our European snakes die generally in captivity during the winter, partly from want of food, partly by the cold nights. The eggs of our oviparous species are deposited during the hottest part of the year, requiring a high temperature for development. Further, though some accounts of Batrachians enclosed in cavities of the earth or trees may be exaggerated, the fact is stated by men whose knowledge and truth are beyond all doubt, that such animals live many years apparently without the supply of food necessary for preserving the energies of the vital functions."* In this country, all Reptiles pass the winter * Dr. A. Giinther on the Geographical Distribution of Reptiles. — Proceedings of Zoological Society. EEPTILES AND SNAKE-STONES. 11 in a state of repose, retiring to holes, clefts, or other available places, apparently secure from disturbance, either in company or singly, for a quiet six months' ' nap/ During this period no food is taken, growth is impeded, the circu- lation is tardy, respiration is low, and the semblance of death is almost complete. In the spring the warm sun quickens their blood, awakens them from their dreams, and again they crawl or leap into active existence, to the terror of ' unprotected females ' and the insect life on which they prey. The curious habit they have of changing their habits, or casting off the outer cuticle of their skins periodically and then devouring them, offers an economical suggestion to those who advocate ' the utilization of waste substances/ in respect to cast-off clothes. Indeed, we are not altogether innocent of devouring our old clothing, but with this difference between our- selves and the reptiles, they appropriate them immediately and in their unchanged condition, ours suffer mutilation, and manifold intermediate changes, before they enter our mouths. Although Reptiles are neither sufficiently nu- merous nor venomous in our temperate climes to give 'the traveller serious alarm, such is far from being the case in tropical countries. There we consequently hear of snake remedies, snake 12 OUR REPTILES. charms, and snake charmers, to an almost un- limited extent. Any one who has paid attention to the Materia Medica of hot climates knows how common ' snake-roots ' and antidotes to snake poison are in all such countries. In many in- stances these substances are in themselves per- fectly useless, and derived their reputation in a great measure from their external resemblance in form to the sinuous or coiled reptile. In many others they are only stimulant or tonic. The most notable of remedies is the snake- stone, not only because of the wonderful powers ascribed to it, but also on account of the belief still entertained, even by many Europeans, of its marvellous curative properties. There is some confusion with regard to it, on account of its numerous imitations. The true snake-stone of the East is undoubtedly a kind of Bezoar or biliary concretion found in the stomach of various animals. Factitious Bezoars are generally either of calcined bone, gypsum, or other ab- sorbent material. The Zuhr Mohra or Zelwr Morah, as it is called in India, is a kind of Bezoar celebrated in Eastern works as a remedy for snake-bites, hydrophobia, &c., and Dr. Ainslie says it is supposed by the Hindoos to possess sovereign virtues as an external appli- cation in cases of snake-bites or stings of scorpions ; and its various Oriental names imply KEPTILES AND SNAKE-STONES. 13 that it destroys poisons. Dr. Davy, on examin- ing what are called snake-stones in India, found them to be Bezoars. The same kind of sub- stance is known in the island of Ceylon under the name of Pamboo Kaloo. Berthollet mentions eight kinds of Bezoar, which are chiefly phos- phates. These were deemed efficacious not only when taken as medicine, but even when merely carried about the person, so that credulous people would hire them on particular occasions for a ducat per day. A single Oriental Bezoar has been known to sell for six thousand livres. The goat Bezoar was found in the fourth stomach of the Capra agagrus of Persia, and was said to be oblong, of the size of a kidney-bean, shining, and of a dark green colour. This was doubtless the most esteemed as a snake-stone. An account, recently published, of one of these snake-stones, which has great reputation in the island of Corfu, thus describes the manner in which it is employed :* — When a person is bitten by a poisonous snake, the bite must be opened by a cut of a lancet or razor longways, and the stone applied within twenty-four hours. The stone then attaches itself firmly on the wound, and when it has done its office falls off ; the cure is then complete. The stone must then be thrown into milk ; whereupon it vomits the poison it has absorbed, which remains green upon the top of the P. M. Colquhoun, in All the Year Round, No. 139. 14 OUR REPTILES. milk, and the stone is then again fit for use. This stone has been from time immemorial in the family of Ventura, of Corfu, a house of Italian origin, and is notorious, so that peasants immediately apply for its aid. In a case where two were stung at the same time by serpents, the stone was applied to one, who recovered, but the other, for whom it could not be used, died. It never failed but once, and then it was applied after the twenty-four hours. Its colour is so dark as not to be distinguished from black. In confirmation of the above, another writer adds :* — While in Corfu, where I resided some years, I became slightly acquainted with the gentleman in question, Signor Ventura, of the Strada Keale, Corfu. His family is, as stated, of great antiquity in the island. He does not know exactly when the stone first came into their possession, but conjectures it was brought from India by one of his ances- tors. I have myself never seen this remarkable stone, but am fully satisfied as to its efficacy, as I have constantly heard of people being cured by it ; in fact, the first thing the Greeks do when bitten by a venomous snake, of which there are several species in Greece, is to apply to Signor Ventura. The stone is then applied, exactly in the manner described above, and the patient in due time is cured. The instance alluded to where one died while it was being used for another, is of a countryman who was bitten by the viper while cutting myrtle or bay for church decoration. He as soon as bitten ran to the town, distant some miles, and arrived when the stone was in use. When it was pro- cured for him, it would not adhere ; for it seems this singular stone requires to rest in milk for some time, to vomit, as it were, the poison absorbed.

The stone was broken by a very clever but unscrupulous native physician, who procured it to look at it, as he said, but who broke it in halves, and subjected one half to the most severe tests, totally failing, however, to discover its component parts. The fracture of the stone has slightly impaired its curative power, and in consequence I have heard the physician, Dottore , railed at in no very measured language by the Greeks. Sir Emerson Tennent gives an account of the Pamboo Kaloo of Ceylon, which is employed for the same purposes as the above, and the know- ledge of such a use he thinks was probably communicated to the Singhalese by the itinerant snake-charmers of the Coromandel coast. " On one occasion/' he writes, " in March, 1854, a friend of mine was riding with some other civil officers of the Government along a jungle path in the vicinity of Bintenne, when they saw one of two Tamils, who were approaching them, sud- denly dart into the forest and return, holding in both hands a cobra de capello, which he had seized by the head and tail. He called to his companion for assistance to place it in their covered basket ; but in doing this he handled it so inexpertly that it seized him by the finger and retained its hold for a few seconds, as if unable to retract its fangs. The blood flowed, and intense pain appeared to follow almost im- mediately ; but with all expedition the friend of the sufferer undid his waistcloth, and took from 16 OUR EEPTILES. it two snake- stones, each of the size of a small almond, intensely black and highly polished, though of an extremely light substance. Then he applied one to each wound inflicted by the teeth of the serpent, to which the stones attached them- selves closely, the blood that oozed from the bites being rapidly imbibed by the porous tex- ture of the article applied. The stones adhered tenaciously for three or four minutes, the wounded man's companion in the mean time rubbing his arm downwards from the shoulder towards the fingers. At length the snake-stones dropped off of their own accord ; the suffering appeared to have subsided; he twisted his fingers till the joints cracked, and went on his way without concern/' It would appear that Sir Emerson submitted one of these snake-stones to Professor Faraday for chemical examination, which re- sulted in the professor giving his opinion that it was a piece of charred bone which had been filled with blood, perhaps several times, and then carefully charred again. The ash was almost entirely composed of phosphate of lime. Captain Napier mentions an instance of the efficacy of the stone. One of the soldiers having been bitten by a scorpion, he says, " I applied the stone to the puncture; it adhered imme- diately, and during the eight minutes that it remained on, the patient by degrees became EEPTILES AND SNAKE-STONES. 17 easier, the pain diminishing gradually from the shoulder downwards until it appeared entirely confined to the immediate vicinity of the wound. I then removed the stone : on putting it into a cup of water, numbers of small air-bubbles rose to the surface. In a short time the man ceased to suffer any inconvenience from the accident/'* Who will deny the evidence of such facts, simply because they cannot understand them ? Mr. E. Newman remarks very pertinently on this same question : — cc I have often been asto- nished at the ridicule thrown over facts that we cannot understand. Men of learning who laugh at a phenomenon they have not seen, always remind me of giggling girls who titter when they hear two persons speak any language but their own ; the cause of cachinnation is the same, simple ignorance. "f Whether ' snake- stones ' be the true Bezoar or the factitious animal charcoal, the principle of action is much the same ; both are absorbents, and both chiefly consist of phosphate of lime. The first object appears to be inducing the blood to flow freely to the wound, and then the remedy is applied. It is very much like sucking out * Gosse's " Romance of Natural History." t The Zoologist, p. 6983. C 18 OUR REPTILES. the poison ; and of course the sooner this is done after the wound is inflicted the better. After the virus becomes disseminated through the blood, it is useless to suck at the portal by which it entered. In cases of poisoning by the bite of a viper, cupping, and the application of leeches have been effectual ; such remedies, however, would be insufficient against the poison of the more noxious tropical reptiles. We are not aware that the ' stones ' alluded to are worn as charms, amulets, or preservatives against the bites of venomous serpents, but such things are not uncommon in Eastern countries. As the teeth of a tiger are sometimes worn as a charm against attack from that animal, so perhaps the fangs of a serpent may be regarded as a pre- servative against the venom of serpents them- selves. It is a current belief amongst the natives in some countries where serpents abound, that any one swallowing the contents of the poison apparatus of venomous snakes is thereby preserved from any ill effects accruing from the bite of a serpent of that particular species. Another kind of ' snake-stones/ adder-gems, ovum anguinum or snake eggs, enter into the ancient superstitions of our own country. Bor- Jase tells us * that " in most parts of Wales, and * " Antiquities of Cornwall," p. 137. EEPTILES AND SNAKE-STONES. 19 throughout all Scotland, and in Cornwall, we find it a common opinion of the vulgar that about Midsummer-eve (though in the time they do not all agree) it is usual for snakes to meet in companies, and that by joining heads together and hissing, a kind of bubble is formed, which the rest, by continual hissing, blow on till it passes quite through the body, and then it im- mediately hardens, and resembles a glass ring, which whoever finds shall prosper in all his undertakings. The rings thus generated are called Gleinau Nadroeth; in English, snake- stones.-" In winter the viper may often be found in its hybernaculum^ several individuals together, intertwined and in an almost torpid state. From this circumstance probably some of the notions connected with the stones alluded to may have been derived. Mason, in his " Caractacus," puts into the mouth of a Druid the following pas- The potent adder-stone Gender'd 'fore th' autumnal moon : When in undulating twine The foaming snakes prolific join ; When they hiss, and when they bear Their wondrous egg aloof in air ; Thence, before to earth it fall, The Druid, in his hallow'd pall, Eeceives the prize, And instant flies, Follow'd by th' envenom'd brood Till he cross the crystal flood. c 2 20 OUR REPTILES. The glass beads, in more recent times em- ployed as charms, were used as a substitute for the rare ' snake-stones/ These " beads are not unfrequently found in barrows,* or occa- sionally with skeletons whose nation and age are not ascertained. Bishop Gibson engraved three : one, of earth enamelled with blue, found near Dolgelly, in Merionethshire ; a second of green glass, found at Aberfraw; and a third, found near Maes y Pandy, Merionethshire. "f Some have affirmed that in Cornwall, where they retain a respect for such amulets, they have a charm for the snake to make the ' milprev/ as it is termed, when they have found one asleep, and stuck a hazel wand in the centre of her spiral. " The country people," says Dr. Borlase, " have a persuasion that the snakes here breathing upon a hazel wand produce a stone ring of blue colour, in which there appears the yellow figure of a snake, and that beasts bit and envenomed, being given some water to drink wherein this stone has been infused, will perfectly recover of the poison." We will leave Pliny alone J with his ovum anguinum, and the various other authors who have * Stukeley's " Abury," p. 44. t Brande's " Popular Antiquities," iil p. 371. J Nat. Hist., lib. xxix. c. 12.

Enlarged view of the upper surface of the head, showing the form and arrangement of the plates.* THE Scaly or viviparous Lizard is a common inhabitant of heaths and banks in elevated dis- tricts in England and Scotland, whilst it appears to have been one of the few reptiles which St. Patrick permitted to remain within the limits of the Emerald Isle. To what circumstance such forbearance in this instance is due chroniclers seem to have been unable to tell. In some seasons, as for instance in I860, this lizard is * Milne-Edwards in "Ann. des Sc. Nat.," ser. i. vol. xvi. t. 5, f. 5. COMMON LIZAED. 23 found in vast numbers everywhere in the county of Down. The observer who records its appear- ance in such plenty on the above occasion remarks, as a singular circumstance, that they never occurred there before, except a single individual at a time, and those at long intervals.* Lord Clermont observes that it is never found in low countries, but frequents mountain districts in the greater part of North and Central Europe, and is common in Switzerland, Germany, Poland, and France, as well as in Scotland, England, and Ireland. In Italy it is only found in the Alpine regions of the north, and it also inhabits the hilly parts of Belgium and Eussia.f This lizard differs in a most important point from the other species to be mentioned, and on this account has been placed by naturalists in a new genus called Zootoca, from the Greek word zooS) ' life/ and tokos, ' offspring/ on account of its young bursting through the very thin membrane-like covering of the egg at the time of birth, and are, therefore, ovo- viviparous ; in which feature this lizard resembles the Viper. The young, as soon as they are born, have the free use of their limbs, and run about in com- pany with their parent, soon commencing the * The Zoologist, p. 7172. t Clerinont's " Quad, and Kept.

The specific name of vivipara has a Latin origin, with a like meaning to the generic. This lively little reptile will often be found sunning itself between spring and autumn. All its movements are exceedingly graceful and vivacious. In an instant it darts upon an insect coming within its range, which as speedily disappears down its throat. Like the slow-worm and sand lizard, it is often the object of persecution, though itself perfectly harmless ; but, on account of its reptile form, does not escape calumny. During summer the pregnant female may be discovered basking in the direct rays of the sun, and is then far less willing to be dis- turbed than at other seasons. Tradesmen who supply materials for aquaria, fern- cases, and domestic vivaria, tell us that while they find a ready sale for the newts, there is such small demand for lizards, because " people are afraid of them;" that they seldom keep any on hand, but collect and supply them to order. This is a foolish prejudice, because they would make an agreeable addition to the attractions of a fernery, and assist in keeping it free from insects. Their movements are more graceful and rapid than those of the newts, and certainly would not require any larger amount of attention. This species is smaller than the Sand Lizard, COMMON LIZARD. 25 not exceeding from five and a half to six inches in length. The tail is longer in proportion, and of a different shape, retaining the same thickness for the first half of its length, and then diminishing gradually to its extremity ; the palate is without teeth, the temple is covered with small polygonal plates, with a large angular one in the centre. The scales on the back are long, narrow, and hexagonal, and less distinctly keeled than in the next species. The head is more depressed and the nose sharper. The plates of the belly are in six rows, with two small marginal series ; the pre- anal plate is bordered by two rows of scales. The fore legs reach to the eye, the hind legs extend along two -thirds of the sides ; pores from nine to twelve on each thigh. The back is brown, olive, or reddish, with a black band on each side from the head to the tail ; a second dark band runs along the side, and is edged with white. The under parts are spotted with black upon a whitish ground, generally with a bluish or greenish tinge.* The relative size and viviparous character are the best features whereby to distinguish this species from the next. * Lord Glenn ont's " Keptiles of Europe," p. 184. 26 OUR REPTILES.

It seems to be pretty widely distributed over Europe, being found almost everywhere except in the extreme North; confined more especially to lowland districts.

It appears to occur freely in the neighbourhood of Poole, but we do not remember to have met with records of its occurrence in the North of England, or in Scotland, although it may have been confounded with the foregoing, especially as it is evidently a Northern rather than a Southern species. Unlike the Scaly Lizard, which is in reality the common lizard with us, it is oviparous, the female laying twelve or more eggs in the sand, and leaving them to be hatched by the heat of the sun. She hollows out a cavity, or rude nest, for the purpose, and covers her eggs with the sand. It possesses a ' snappish ' temper, is not readily domesticated, and refuses food under confinement. Like other reptiles, it passes its winters in a state of repose. The liver, bile, excrements, and eggs of the Lizard were in former times employed as remedies in certain diseases, and the entire animal has been proposed as a substitute for the Scink, a reptile allied to the Lizards, which had a great reputation in olden times, the use of which has very recently been attempted to be revived. Dr. Gosse, of Geneva, has maintained that the ancients were justified in employing the Scink in medicine, inasmuch as it possesses powerful 28 OUR EEPTILES. stimulant and sudorific properties, which might be usefully employed in various diseases.* In Mr. P. L. Simmonds's interesting and amusing " Curiosities of Food/' several species of reptiles are enumerated as affording food to the natives in the various countries in which they are found. Of these, the Iguana holds one of the chief places in public esteem. This is a gigantic lizard found in many tropical countries, where it attains a length of three feet, and has flesh " which is reckoned as delicate as chicken, and but little inferior to turtle in flavour." Humboldt remarks that in inter- tropical South America, all lizards which inhabit dry regions are esteemed delicacies for the table. The gi- gantic crocodile, alligator, gavial, and cayman, are also served at repasts. This, however, is some- what foreign to our subject, and all who are interested in reptilian delicacies we must refer to the book in question. The fossil Saurians of bygone ages were the giants of those days. Dr. Mantell thought it probable that the largest iguanodons may have attained a length of from sixty to seventy feet. The Labyrinthodons were also of considerable size. Eemains and traces of numerous reptiles have been found in the strata of our own islands. * See Moquin Tandon's " Medical Zoology," p. 69. THE SAND LIZARD. 29 fc Impressions of the feet of a Labyrinthodon were found by the late Mr. Hugh Strickland in the lower Keuper sandstone of Shrewly Common, Worcestershire ; and bones and teeth have been discovered near Kenilworth, in the Permian sandstones of the geological surveyors, as well as in the upper Keuper beds. Five species of Labyrinthodont reptiles have been found in Great Britain, all of which must have been very unpleasant -looking animals, with fearful jaws, adapted especially for biting. And yet such animals lived on the shores of a sea- bed which now constitutes much of the pleasant vales of Worcestershire and Cheshire, the shores of the New Eed Sandstone sea.* Returning from c stewed Iguana' and extinct reptiles to the little Lizard of the present dege- nerate days, we may observe, that though neither formidable in size, repulsive in appear- ance, nor in any sense aggressive or noxious, it has many enemies, some amongst bipeds with feathers, and some amongst bipeds without. It has personal interest in the ' smooth snake ' and its proximity to its own locality ; for that reptile has a great predilection . for a lizard at luncheon, whilst the common snake prefers a frog or a newt. But the most relentless perse- * " Old Bones," by the Rev. W. S.

That it is not only inoffensive, but useful in keeping up the balance of nature, by its reduction of insect life, its legitimate prey, is a truth, like the ( small bird question/ which may be ac- knowledged when it is all but too late. There are two varieties of this lizard, indi- cated by their relative colour. In one the general tint is brown; in the other it is green. The most common variety has the back of a sandy-brown colour, sometimes spotted with black, with the sides greenish in the male, but brownish in the female : the belly is white and often spotted. In length it is from seven to nine inches, of which the tail occupies more than half, or nearly two-thirds. The scales of the upper part of the body are roundish or angular, and distinctly keeled ; the plates of the belly are arranged in six rows, of which the two central rows are the narrowest. The tail is covered with from fifty to eighty distinct whorls or rings of scales, which are longer and narrower than those of the back. It is thicker and rather more clumsy than the last species, and the limbs are stouter and stronger, and is less graceful and vivacious in its movements. There are other THE SAND LIZARD. 31 and more minute points of difference, but these are of interest rather to the zoologist than to the general reader. It may be observed, however, that in this species there are to be found, in addition to the ordinary teeth at the margin of the upper and lower jaws, also a few very small ones seated on the back part of the palate, and which are wanting in the common lizard. Professor Bell states on the faith of a gentle- man of his acquaintance, that the brown varieties are confined to sandy heaths, the colours of which are closely imitated by the surface of the body, and that the green variety frequents the more verdant localities. This, he adds, he had not been in a position either to refute or confirm, and could only vouch for the existence of two such varieties, at a comparatively short distance from each other. 32 THE GREEN LIZARD. (Lacerta viridis.) Enlarged view of the side of the head, showing the form and arrangement of the plates.* Is the Green Lizard really a native of Britain ? That is the very knotty question which we desire to settle, both for our own satisfaction and that of our readers, but cannot divest our minds of a lingering doubt whether it may not have descended to us in a similar manner to the shower of edible frogs which Mr. Penney rained down upon Foulmire. That this species has been found in Great Britain, in an apparently * Milne-Edwards in " Ann. des Sc. Nat.," ser. i. vol. xvi. t. 7, f. 2.

If we turn over the pages of the earlier volumes of the Zoologist we here and there encounter little facts of a very stubborn nature, relative to the Green Lizard, in every instance guaranteed by some name well known in the annals of science. One of the earliest of these notes is by Dr. Bromfield,* in which he states
