naso-rostral plate small and quadrangular ; fronto-nasal larger, quadrangular ; the anterior side much
the longest. Frontal plate six-sided; the two anterior sides, where they join on the. mesial line, form
an acute projecting point, the two hinder sides considerably produced, and unite at an. acute angle
between the occipital plates. Occipital plate subovate, the anterio-inferior portion prolonged to
the postocular plate ; the outer edge of each occipital plate, towards its. hinder extremity, bounded
by a small quadrangular plate. ..Nasal plate elongate, five-sided, truncated anteriorly; triangular
posteriorly, the nostril towards the anterior edge; preocular plate small, subtriangular; postocular
plate kidnéy-shaped, or subcordaté. Plates of upper lip, exclusive of rostral, 'Sty. of lower, exclusive
of mental, the same. Scales of body in oblique rows, each row forming' an angle: on the vertebral
line; towards the head they are subovate, elsewhere subrhomboidal, of somewhat six-sided; the
anterior and posterior sides very short. Plates under the tail entire, like those of the abdomen;
Teeth small. Colour of the upper surface of the head blackish brown; a transverse-band behind the
head liver-brown, or pitch-black; jthe back, the. sides of the head and body, and the upper and lateral
parts of the tail, yellowish brown; the scales of the. back tipped with pale brownish red. The
hinder parts of the head, body, and tail, straw-yellow. Abdominal plates, 168; subcaudal plates, 48.
Length from nose to base of tail, 5 inches; length of tail, 13 lines ; diameter at thickest part.of body,

Inhabits the whole of Southern Africa, and is generally observed among dry grass, or in loose
soil, more especially near the roots of shrubs.
ELAPOMORPHUS CAPENSIS, n. s.*
Head and body of equal width, the latter slightly tapered towards the tail. Body sub-
cylindrical, not so thick as a goose-quill; tail cylindrical, tapered, and pointed. Head subovate;
nose arched; eyes small. Rostral plate small and semicircular; naso-rostral plates small and four
sided; fronto-nasal plates much larger, five sided, the two hinder sides united behind at an angle.
* ELAPOMORPHUS.—Ch. Gen. Teeth of maxillae slender, the hindermost longer than the others, and grooved anteriorly.
Plates of upper surface of head as in Coluber. Nasal plate large, nostril in its centre; frenal plate wanting; preocular
and postocular plate, each one; plates under tail similar to those of abdomen. Pupil circular.
Frontal plate six sided; the two hinder sides prolonged, and behind form an acute angle. Palpebral
plates small, four sided; occipital plates large, six sided, the apex or hindermost side very short; a
rather large plate external to hinder extremity of each occipital plate. Nasal plate somewhat five
sided. Preocular and postocular plates small, subtriangular. Plates of upper lip, exclusive of rostral,
six, the hindermost very large; of lower lip, exclusive of mental, six, the third and fourth large; sub-
mental plates two pairs, the hinder pair smallest. Scales of body subrhomboidal, or imperfectly six
sided, imbricate, and arranged in oblique rows, the rows of one side meeting those of the other at an
acute angle; the number of plates in each row sixteen. Colour of the upper and lateral parts of head,
clove-brown; a liver-brown bar across upper part of neck, pointed at each extremity, and separated
from the colour of the head by the intervention of two small pale sienna-yellow spots. Colour of
the back and sides intermediate between sienna-yellow and wine-yellow; of the under parts, pale cream-
yellow. Abdominal plates 166; subcaudal plates 37. Length from nose to anus, 4 inches 8 lines;
length of tail 1 inch.
Inhabits Kaffirland, to the eastward of the Cape Colony. I have placed this in the genus
Elapomorphus, Weighman, without being acquainted with the, characters of the group further than
that Moms. Bibron wrote me, before his death, that Calamaria Blimii, Schlegel, was a species of
Elapomorphus of Weighman. If the species just mentioned belong to this group, the one described
will also belong to it.
TEMNORHYNCHUS, n. g.
Ch. Gen. Head depressed. Lower jaw considerably shorter than the upper. Teeth of maxillae
small, pointed, thinly set, and of equal length. Rostral plate large, anteriorly produced, the edge
cutting; naso-rostral two; fronto-nasal one; nasal one; frenal one; preocular and postocular each
two; submental one pair. Nostril in middle of nasal plate, and a longitudinal groove behind it, as in
Acontias. Pupil circular. Scales of body slightly imbricate, and in oblique rows; a double row of
scales on the under surface of the tail.
TEMNORHYNCHUS, Sundemallii, n. s.

quill, and nearly equal throughout; tail cylindrical, tapered, and terminated by a sharp-pointed horny
spine. Rostral plate large and subtriangular; naso-rostral plates small, triangular, and not contiguous

to the hinder edge of the plate. Frenal plate square; the preocular and postocular plates very small;
the pair of submental plates large, and anterior to them, the first pair of labial scales are contiguous
internally. Plates of upper lip, exclusive of rostral, seven; of lower lip, exclusive of mental plate,
eight. Eyes small. Scales of the body more or less distinctly six sided, those of the sides largest;
