pursuers to despair of success in taking it. It flew unweariedly, turned with the rapidity of a butterfly, and alighted and rose again as readily as that active insect. It is a male and mature.

HABITAT.-Central region of sub-Himalayas.
REMARK. Nearly allied to Auritus, but differs therefrom by disunited ears, fewer molars, a flat inner ear, shorter fur, and nude ears, besides its more uniform colour. The joints of the digits also differ, showing how little dependance can be placed upon this mark which yet Cuvier, Geoffroy and H. Smith make the corner-stone of their general classification of the Family!
I subjoin a synopsis of the several species thus far ascertained.
*N. B. This is an undescribed species with the general structure of labiata, but distinguished remarkably by having the entire legs and caudal membrane clad in the fur of the body, which is thick and woolly. Colour bright rusty above, sooty below; the hairs tipt hoary. Digits rusty. Membranes blackish. Snout to rump 2 inch. Head §. Ears. Tail 1. Expanse 13 inchs. Arm 14. Forearm 13. Long finger 34. Head depressed. Eyes and ears remote. Eyes small. Ears moderate rounded. Inner ears spire-shaped. Nostrils lateral-salient. Cheeks tumid. Thumb with 3 joints. Index with 2. Mid with 4 and a cartilaginous appendix. Annular and small digits each with 3. Tail ample, 7 jointed, and nearly square. Teeth all remarkably blunt. Penis with a corneous tip ending in two horn-like crura. Helix posteally with a sacculate reduplication, but no prolongation towards the gape as in labiata. Intestines 7 inches. No cœcum. Stomach hemisphe

(Continued from No. CLXXX.)
FAM. TYPHLOPIDE, GRAY.
GEN. PILIDION, Duméril and Bibron.
Head covered with shields, cylindrical, very short, as if truncated, convex above, declivous in front; muzzle rounded; rostral shield like a large rounded cap covering the head and muzzle; an anterior frontal, a frontal, a pair of supra-orbital-, ocular-, nasal-, and fronto-nasal shields; neither parietals, inter-parietals, nor præ-orbitals; nostrils hemispherical, under the muzzle, between the nasal-and fronto-nasal shields; eyes excessively small, hidden by the ocular shields.
PILIDION LINEATUM, (Boie.)
SYN.-Acontias lineatus, Reinwardt, MS.
Typhlops lineatus, H. Boie.
Typhlops lineatus, Gray in Griffith, A. K.
Typhlops lineatus, Schlegel.
Pilidion lineatum, Duméril and Bibron.
Typhlinalis lineatum, Gray: Catal.
Ground-colour pale gamboge or orange, uniform on the head, the apical third of the tail, and the abdomen; interrupted on the back and sides by 12 longitudinal, serrated brown lines, produced by a minute triangular spot on each side of the scales.
HABIT. Pinang Hills.
Java, Sumatra, Singapore.
A single individual, captured by Sir William Norris, differs from the description given by M. M. Duméril and Bibron in the comparatively
greater dimensions of the tail. It is strongly arched; its length equals twice the breadth of the head; it is covered with 16 transversal series of scales, and it is considerably thicker than the rest of the uniformly cylindrical body. The anterior frontal shield is very broad, larger than the frontal. It was of the following dimensions:
Circumference of the trunk inch; of the tail g inch.
GEN. TYPHLOPS, Schneider.
Head covered with shields, depressed; muzzle rounded, covered above and beneath by the rostral shield; an anterior frontal, a frontal, a pair of supra-orbitals, one or two pairs of parietals and inter-parietals; a pair of nasals, fronto-nasals, præ-orbitals and oculars; nostrils lateral, hemispherical, opening in the suture between the nasal and frontonasal; eyes lateral, more or less distinct; pupil round.
TYPHLOPS NIGRO-ALBUS, Duméril and Bibron.
SYN.-Argyrophis bicolor, Gray: Catal.
Shining black above; on the head some transversal and radiating whitish yellow lines; scales of the back edged with white; beneath whitish yellow.
HABIT. Pinang Hills, Singapore.
This species is closely allied to T. diardi, Schlegel,* an inhabitant of Assam and the Khassia Hills.
Of two individuals observed, the
Circumference of the trunk inch, of the tail 1 inch.

Typhlops braminus, Cuvier, apud Duméril and Bibron.
Shining copper-coloured, or brown of various shades above, paler beneath. Some individuals of a uniformly bluish white. All the scales with a dark brown spot at the anterior part. The shields of the head have a whitish line close to their margins. In the young the latter is crenulated, and the sides of the head, lips, throat, the anal region, and the point of the tail are yellowish or whitish, and the body is semitransparent.
HABIT.-Pinang, Singapore, Malayan Peninsula.
Canton-Province, Philippines, Guam (Marian Isles,) Java,
In the Malayan countries this species is numerous in hills and valleys. The eyes are black, the pupil round, which is also the case in T. nigro-albus. The largest of a great number examined was of the following dimensions :—
Length of the head,
Ditto ditto trunk,
Ditto ditto tail,
Circumference of the neck 4 inch; of the tail ğ inch,
The preceding species of this family are all of similar habits. They mostly live under ground, but appear occasionally in shady places, particularly after showers of rain, in Bengal, in the rainy season. They are very agile, and appear to make use of the horny point of the tail as a propeller. When taken, they frequently press it against the hand in their attempts to escape.
