Large Leaf-Bat (Jerdon's No. 17)HABITAT.—Nepaul, Darjeeling, Khasya Hills.
DESCRIPTION.—Ears very large, much longer than the head; broad, acutely pointed; nasal apparatus very complicated; the lower leaf very large, concealing the upper lip like a door knocker; the upper leaf like a graduated spire; ears transversely striate; a rather large semi-circular lobe at base of ear; fur long, dense, soft, and lax, slightly curled or woolly black with a silvery grizzle, or greyish-black or rich chestnut-brown.—Jerdon.
SIZE.—Length, 3¾; tail, 1¾; wing expanse, 17 inches.
HABITAT.—Chybassa, Central India, Mussoorie(?)
DESCRIPTION.—Ears large; anti-helix moderately developed; upper leaf triangular acute; tail extending beyond the tibia; color above light brown; paler beneath.—Jerdon.
SIZE.—Head and body, 2½ inches; tail, 1½ inch; wing expanse, 12 to 14 inches.
HABITAT.—Nepaul, Mussoorie.
DESCRIPTION.—Upper process like a barbed spear-head; central one small and narrow, a little expanded at the summit; anti-tragus less developed than usual; lips simple; colour a uniform deep brown, with tips of the hair paler, and somewhat rusty.—Jerdon.
SIZE.—Head and body, 2-5/8 inches; tail, 1-7/8 inch; wing, 15½ inches.
The tail of this species seems unusually long. It is found in cavities of rock, and issues forth soon after dusk—sooner, according to Hodgson, than the species of vespertilio.
HABITAT.—Lower Himalayan range, Darjeeling, Mussoorie, &c.
DESCRIPTION.—Colour above dark brown, with a slight shade of chestnut; underneath brown, with a sooty cast; fur very long, dense and soft; ears distinct, with an additional rounded lobe below, measuring anteriorly nearly three-fourths of an inch; point of the facial crest moderately developed; length from the tip of the nose to root of tail three inches; tail half an inch; length of fore-arm two inches; expanse of the wings eleven inches. Although allied to Mr. Hodgson's R. tragatus, possesses distinct characters.—Horsfield.
SIZE.—As given by Horsfield above.
This bat was first sent from Darjeeling by Mr. J. T. Pearson, and was named after him. It has also, according to Jerdon, been found by Captain Hutton at Mussoorie; it is therefore reasonable to suppose that it inhabits the whole range of the lower Himalayas. One striking difference between it and the last species is the very short tail, and it is easily to be recognised by the great length of the fur.
HABITAT.—Ceylon, Burmah, and perhaps the Malabar coast.
DESCRIPTION.—Above bright red ferruginous brown; tips of hair darker, paler beneath; ears pointed and external; edge deeply emarginated; internal edge and basal third of external surface hairy; anti-helix well developed; nasal process apparently very similar to that of R. mitratus (Kellaart). Upper leaf triangular, emarginate at the tip, reaching above the base of the ears (Jerdon).
SIZE.—Head and body about 2-3/10 inches; tail, 1 inch; wing extent, 12 inches.
This bat seems to vary much in colour. Kellaart says some are of a brighter red than others, and a few had a yellower tinge. Another marked variety was of a uniform pale yellow brown.
HABITAT.—India generally.
DESCRIPTION.—Ears large, pointed, externally notched; tragus broad; tips of upper nose-leaf triangular, with its sides well emarginate, reaching above the base of the ears; no upper incisors [as in Megaderma lyra]; lower molars only five; canines very large; fur short, crisp; colour above smoky brown in some, reddish brown in others, and golden rufous in some; beneath paler.—Jerdon.
SIZE.—Length, 2-3/8 inches; tail, 1-1/8; wing expanse, 13 inches.
Hodgson considers this bat as allied to the two following species. It is the R. lepidus of Blyth.
HABITAT.—Lower Himalayas.
DESCRIPTION.—Ears very large, broad, oval, with pointed recurved tip, and a large obtuse tragus; anterior central crest of nose-leaf produced in front over the top of the flat transverse front edge; hinder leaf lanceolate triangular; above sooty brown or light earthy olive-brown, paler below, some with a rufous or Isabelline tint; no pubic teats.—Jerdon.
SIZE.—Head and body, 1¾ inch; tail, ¾; wing expanse, 9¾.
HABITAT.—Nepaul.
DESCRIPTION.—Ears not larger than the head, obtusely pointed and ovoid; nasal appendage quadrate, with a transverse bar nearly surmounting it; upper leaf triangular, with slightly emarginate sides; clear brown above, paler below and on head and face.
SIZE.—Head and body, 1½ inch; tail, 1¼; wing expanse, 7½.—Jerdon.
HABITAT.—Ceylon.
DESCRIPTION.—Above rufescent, beneath ashy brown; face slightly fulvous; round the base of the ears and on the sides of the posterior half of the body bright fulvous; tail enclosed in the interfemoral membrane.
SIZE.—Head and body, 2½ inches; tail, 1; wing expanse, 10 inches.
This is a doubtful species. Dr. Kellaart got one from Amanapoora hill at Kaduganava. He says: "As the specimen reached us in a dried condition, we are unable to say anything more about its nasal processes than that in place of a transverse process above the nostrils it had a small triangular peak over the usual horse-shoe process surrounding the nasal opening. This triangular crest was hairy; superiorly there was no appearance of a sac above it to the best of our recollection."
HABITAT.—Southern Andaman Island.
DESCRIPTION (apud Dobson).—Like R. affinis generally, but the anterior horizontal horse-shoe shaped membrane is very broad, completely concealing the muzzle when viewed from above, as in R. Pearsonii; the posterior terminal leaf is also much longer, produced backwards between the ears, and not concave on the sides as in R. affinis. The thumb is also much longer. Fur bright reddish brown above and beneath.
HABITAT.—Burmah, Yunan.
DESCRIPTION.—Light brown above, greyish brown beneath; ears slightly shorter than the head, sub-acutely pointed; anti-tragus large, separated by a deep angular notch; lower lip with three vertical grooves.
SIZE.—Length of head and body from 1 to 1¾ inch.
