Genus Harpiocephalus
This is also the genus Murina of Gray. Dr. Dobson explains his acceptance of the former term in the following way: that he first accepted Murina on the score of priority in a paper showing that Harpiocephalus and Murina must be united in a single genus; but finding afterwards that Gray had founded Murina on a specimen of what he believed to be Vesp. suillus (Temm.), but which was in reality a specimen of a very different species from Darjeeling, belonging to the same section of the genus as Vespertilio harpia (Temm.) the type of his genus Harpiocephalus, it remained therefore either to discard both names or to retain Harpiocephalus, in which course he was supported by Professor Peters, to whom he mentioned the facts.
Horsfield’s genus Lasiurus is included in this one, though Jerdon considers it distinct from Murina.
Muzzle elongated, conical; nostrils prominent, tubular; produced beyond the upper lip, opening laterally or sublaterally, emarginate between; crown of the head scarcely raised above the face line; ears thin, generally covered with glandular papillæ; tragus long, attenuated towards the tip, and inclined outwards; thumb very large, with a large, strongly curved claw; wings around interfemoral membrane very hairy.—Dobson.
Dentition: Inc., 2—2/6; can. 1—1/1—1; premolars, 2—2/2—2; molars, 3—3/3—3.
No. 99. HARPIOCEPHALUS HARPIA.
Lasiurus Pearsonii (Horsfield) (Jerdon’s No. 50).
Habitat.—Darjeeling and Khasia hills.
Description.—“Fur above very soft, silky, and rather long; colour on the head, neck, and shoulders brownish grey, with a ferruginous cast, variegated with whitish hairs; the rest of the body above, with the base of the membrane, the thighs and the interfemoral membrane, have a deep bay or reddish-brown hue, and delicate hairs of the same colour are scattered over the membrane and project from its border; the body underneath is thickly covered with a grey fur, which is paler on the breast and body; the interfemoral membrane marked with regularly parallel transverse lines” (Horsfield). Ears ovoid; tragus rather long, nearly straight, acute at the tip (Jerdon). Muzzle rather short, obtusely conical; end of nose projecting considerably beyond the lip, consisting of diverging tubular nostrils opening laterally, with a slight emargination between each (Dobson).
Size.—Head and body, 3 inches; tail, 1½ inch; expanse, 14. Hodgson, who procured it at Darjeeling, writes of it: “Entire legs and caudal membrane clad in fur like the body, which is thick and woolly. Colour bright rusty above; sooty below, the hairs tipped with hoary.”
This bat is, for its size, one of the most powerfully armed with teeth. The skull reminds one of that of a dog or hyæna in miniature; the teeth are very stout, the canines blunt and conical, and the cusps of the molars short and blunt, well coated with enamel; the jaws are correspondingly muscular and adapted to the food of the animal, which consists of hard-shelled beetles, the crushed cases of which have been found in its stomach.
No. 100. Harpiocephalus (Murina) SUILLUS.
The Pig-Bat (Jerdon’s No. 51).
Habitat.—Darjeeling (Jerdon); Malayan archipelago.
Description.—Muzzle narrow, elongated; nostrils very prominent, which, viewed from below, resemble in shape a small hour-glass placed horizontally at the extremity of the muzzle; ears moderate, shorter than the head, rounded at the tips; tragus moderately long, attenuated above and slightly curved outwards; fur light greyish-brown; extremities dark brown; beneath light greyish-brown throughout.—Dobson.
Size.—Head and body, 1¾ to 2 inches; tail, 1½ inch; expanse 9 to 10.
