[June 14, Fingers entirely webbed, the disks smaller than the tympanum; toes webbed to the disks, which are smaller than those of the fingers; subarticular tubercles feebly developed. Tibio-tarsal articulation reaching the tip of the snout. Skin smooth, feebly granulate on the belly; a slight dermal fringe along forearm and tarsus; a dermal flap above anus and at heel. Yellowish, with a few purplish dots on head and back; a purplish line round the snout, from eye to eye, passing through the nostrils. From snout to vent 43 millim. A single specimen. 7. IXALUS AURI FASCIATUS, Schleg. 8. CALOPHRYNUS PLEUROSTIGMA, Tsch. 9. CALLULA BALEATA, S. Mull. 10. NECTOPHRYNE HOSII, sp. n. (Plate XXX. fig. 2.) Head broader than long ; snout short, obliquely truncate ; canthus rostralis strong; loreal region nearly vertical, concave; interorbital space broader than upper eyelid, slightly concave; tympanum distinct, vertically oval, half the diameter of the eye. Fore limb long and strong; fingers webbed at the base, ending in rather large subtrian-gular expansions, first much shorter than second; toes short, with small distal expansions, extensively webbed, but the three distal phalanges of the fourth toe free; subarticular tubercles well developed ; two small, flat metatarsal tubercles; a tarsal fold. Tarsometatarsal articulation reaching between eye and end of snout. Above with small scattered warts, beneath finely granulate; a short and narrow, but very prominent parotoid gland. Brown; throat blackish. Male with an internal subgular vocal sac. From snout to vent 60 millim. A single male specimen. 11. BUFO QUADRIPORCATUS, Blgr. 12. BUFO ASPER, Gravh. Besides several small and perfectly typical examples, the collection contains a large female, measuring 215 millim. from snout to vent, which agrees in every respect with B. asper except in the much greater development of the parotoid glands, the length of which equals their distance from the end of the snout and twice and a half their width ; they are disposed very obliquely, diverging behind. I have felt tempted to describe this specimen as a distinct species; if I abstain from doing so it is because I can detect no other ground for such a separation than the size and form of the parotoids, a character which varies so much in certain other species of this genus-B. marinus, B. regularis, and B. viridis, for instance. 13.
