The Serpents form a division of the Reptile1 Class too well known by their elongated2 scaly3 bodies, and their total deprivation4 of external members, to require any minute description of their organization. They are also held by the generality of mankind in so much abhorrence5, and regarded for the most part with such strong feelings of unmitigated disgust, that we feel but little inclined to dwell upon their history, how much soever they may on many accounts be considered as deserving of a more extended notice.
They are frequently divided into two great sections; the one, which is by far the most numerous, comprehending[234] all those in which the poison-fangs6 are wanting, and which are consequently dangerous only in proportion to the extent of their muscular force; and the other consisting of those in which the fangs are present, and the bite of which is accompanied with the pouring out of a venomous secretion7. At the head of the first of these divisions rank the Boas, which in the Linnean arrangement comprehended all those snakes, whether venomous or not, whose under surface was covered with narrow transverse plates, and whose tail was destitute8 of rattle9. Later zoologists10 have, however, confined that appellation11 to those among the Linnean Boas, which are without poisonous fangs and have claws near the vent12, and have regarded as a distinct genus the snakes which in addition to these latter characters have the scales of the under surface of the tail so arranged as to form two distinct rows. To the latter, which inhabit the Old Continent exclusively (while the former are all of them natives of America), they have assigned the name of Python.
The present species, which is commonly exhibited under the popular but erroneous title of the Boa Constrictor, appears to be the Pedda Poda of Dr. Russell’s Indian Serpents. It is said by that writer to attain13 a length of eight or ten feet; but living specimens14 have been brought to this country of twice that size, and some of those now in the Tower are fifteen or sixteen feet long. The number of transverse plates on the under surface of the body is stated to be two hundred and fifty-two, and that of the pairs of scales beneath the tail sixty-two. The back is elegantly marked with a series of large irregular brown blotches15 bordered with black; and numerous smaller spots are scattered16 along the[235] sides. The ground colour is yellowish brown, lighter17 beneath.
The extent of muscular power which these serpents possess in common with the Boas is truly wonderful. To the smaller among them the lesser18 quadrupeds and even birds fall an easy prey19; but the larger, when excited by the stimulus20 of hunger, are capable of crushing within their spiral folds the largest and most powerful of beasts. The sturdy buffalo21 and the agile22 stag become alike the victims of their fatal embrace; and the bulk of these animals presents but little obstacle to their being swallowed entire by the tremendous reptile, which crushes them as it were into a mass, lubricates them with the fetid mucus secreted23 in its stomach, and then slowly distending24 its jaws25 and ?sophagus to an extent proportioned to the magnitude of the object to be devoured26, and frequently exceeding by many times its own previous size, swallows it by one gradual and long-continued effort.
Of the mode in which this operation is effected, a detailed27 description is contained in Macleod’s Voyage of His Majesty’s Ship Alceste; and an excellent account has been subsequently given by Mr. Broderip in the second volume of the Zoological Journal from actual observation of the specimens now in the Tower. The vivid description of the latter almost brings before the reader’s eye the lightning dash of the serpent; the single scream of its instantly enfolded victim, whose heaving flanks proclaimed that it still breathed; and its last desperate effort, succeeded by the application of another and a deadly coil. With equal force and fidelity28 it sketches29 the continuation of the scene, when the serpent, after slowly disengaging his folds, placed his head opposite[236] to that of his victim, coiled himself once more around it to compress it into the narrowest possible compass, and then gradually propelled it into his separated jaws and dilated30 throat; and finally presents a disgusting picture of the snake when his meal was at an end, with his loose and apparently31 dislocated jaws dropping with the superfluous32 mucus which had been poured forth33.
The individual figured at the head of the present article is a female; a fact which was proved by the remarkable34 circumstance of her producing in May last, after having been more than two years in the Menagerie, a cluster of eggs, fourteen or fifteen in number, none of which, however, were hatched, although the mother evinced the greatest anxiety for their preservation35, coiling herself around them in the form of a cone36, of which her head formed the summit, and guarding them from external injury with truly maternal37 solicitude38. They were visible only when she was occasionally roused; in which case she raised her head, which formed as it were the cover of the receptacle in which they were enclosed, but replaced it again as quickly as possible, allowing to the spectator only a momentary39 glance at her cherished treasures.
