Show 328 BATRACHIAN COLLECTION IN THE BRITISH MUSEUM. [Apr. 15, two oval, blunt metatarsal tubercles, inner more elongate and nearer its fellow than the tarsal tubercle. The tibio-tarsal articulation reaches the centre of the eye. Skin smooth ; a large, flat, oval lumbar gland. Grey-brown above, with a blackish lateral band; lumbar gland with a black, light-edged ocellus ; hind limbs with dark cross-bands ; hinder side of thighs white-dotted ; lower parts white, speckled with brown. From snout to vent 33 millim. A single female specimen from Venezuela, from Dr. Fischer's collection. BUFO JERBOA. (Plate XXV. fig. 3.) Allied to Bufo leptopus, Gthr., but with still longer hind limbs. The femoro-tibial articulation reaches the shoulder, the tibio-tarsal far beyond the tip of the snout, and the tibia measures two thirds the length of head and body. In B. leptopus the tibia measures half the length of head and bodv, and the tibio-tarsal articulation reaches the eye or between the eye and tip of the snout. Snout strongly projecting; loreal region vertical; interorbital space as broad as the upper eyelid; tympanum close to, and measuring half the diameter of the eye. First and second fingers equal; toes one-third webhed. Upper parts with small smooth warts ; no distinct parotoids. Brown above,limbs with darker cross-bands; anX-shaped dark marking on the middle of the back; throat brown. Male with an internal subgular vocal sac and brown nuptial asperities on the inner finger. From snout to vent 30 millim. A single male specimen, collected by Hr. Grabowsky in S.E. Borneo, and mentioned in the list published by Fischer (Arch. f. Nat. 1885, p. 43) as B. leptopus. It is particularly curious to find in Borneo, which is the home of the most long-legged Rana (R. jerboa, Gthr.), a kind of Toad which by far exceeds all others in the length of the hind limbs.
