Vipera Albizona - Description

Description

The maximum is a little less than 78 cm (for a male), although most specimens are smaller.

The head is relatively large and distinct from the neck. The snout is rounded and covered with small, keeled scales. The nostril is located within a single nasal scale. There are 2-3 apical scales in contact with the rostral. There is normally 1 canthal scale on either side of the head. The large supraoculars are in broad contact with the eye. There are 9-13 circumorbitals. Two scale rows separate the eye from the supralabials, of which there are 7-10. There are usually 10-13 sublabials. The temporal scales are keeled.

Midbody there are 23 rows of keeled dorsal scales. There are 2-3 preventral scales, followed by 149-155 ventrals. The anal scale is single and followed by 23-30 paired subcaudals.

The color pattern consists of a grayish ground color. Running along the midline from the back of the head to the tail is a series of about 30 transversed and pronounced white- and black-edged narrow bands separated by a brick-red brown zone 3-4 scales long and 9-12 scales wide. Lateral spots may be small and in a double series. There are usually two large black, oblique spots on top of the head, as well as a dark stripe running from the corner of the eye back to the angle of the mouth or beyond. The belly is grayish and finely speckled with darker spots.

Famous quotes containing the word description:

    “The next Augustan age will dawn on the other side of the Atlantic. There will, perhaps, be a Thucydides at Boston, a Xenophon at New York, and, in time, a Virgil at Mexico, and a Newton at Peru. At last, some curious traveller from Lima will visit England and give a description of the ruins of St. Paul’s, like the editions of Balbec and Palmyra.”
    —Horace Walpole (1717–1797)

    “The great object in life is Sensation—to feel that we exist, even though in pain; it is this “craving void” which drives us to gaming, to battle, to travel, to intemperate but keenly felt pursuits of every description whose principal attraction is the agitation inseparable from their accomplishment.”
    —George Gordon Noel Byron (1788–1824)

    “To give an accurate description of what has never occurred is not merely the proper occupation of the historian, but the inalienable privilege of any man of parts and culture.”
    —Oscar Wilde (1854–1900)
