Kellaart writes of this bat under his H. aureus. He describes it as head, neck, and body of a bright golden yellow, with a slight maroon shade on the tips of the hairs on the back. Females paler coloured. Frontal sac only in males; the waxy matter of a yellow colour, and quite transparent.
[NO. 59. HIPPOSIDEROS VULGARIS.]
Syn.—PHYLLORHINA LARVATA.
The Common Malayan Horse-shoe Bat.
HABITAT.—Arracan and Malayana.
DESCRIPTION.—"It differs from the last in being rather smaller, and of a brown colour above, much paler at the base of the hairs and at their extreme tips, and lighter coloured below; the ears more apiculated, or rather they appear so from being strongly emarginated externally towards the tip."—Blyth.
SIZE.—2-3/10 inches; tail 1-2/10; wing expanse about 12.
[NO. 60. HIPPOSIDEROS BLYTHII.]
HABITAT.—Ceylon, Fort Frederic.
DESCRIPTION.—Above surface colour a rich dark tawny brown; base of hairs much lighter coloured, of a brighter yellow tinge; beneath paler; face partially blackish; ears black; tip of tail excerted; no frontal sac; membranes blackish; nasal processes as in H. speoris.
SIZE.—Head and body, 2-2/10 inches; tail, 1; wing expanse, 12.
Dr. Kellaart considered this a new and undescribed species, distinguished from H. speoris and H. vulgaris (vel Templetonii—Kellaart) by the greater length of the fore-arm, which is two inches. This remark however does not apply to vulgaris, of which Kellaart himself gives two inches as the length of the radius, and Blyth gives two and a quarter. The absence of the frontal sac would have been a greater proof, but both specimens on which Kellaart made his observations were females; and as colouring is so varied in the bat tribe as to preclude the division of species on this ground, I think we may put this down as a doubtful species on which more information is desirable.
