A short dermal ridge in front of the oesophagus between the minute auditory tubes. Tympanum hidden. Fingers and toes free, the tipes not dilated. Outer metatarsals united. Maxillaries separated by the praemaxillaries. Precoracoids present, cartilaginous, arising from the inner edge of the coracoid and curving hooklike to the middle of the latter (Pl. XIII. fig. 4, ]>c

) ; the front edge of the precoracoids shows an ossified, stylelike clavicle (Pl. XIII, fig. 4, cl

), which reaches the coracoid : * no omosternum : sternum an anchorlike cartilaginous plate. Diapophyses of sacral vertreba strongly dilated ; ileum much prolonged in front of the anterior edge of the diapophysis. Terminal phalanges simple. 2. Chiasmocleis albopunctata BTTGR. (PI. XIII, fig. 4, 5.) Engystoma albopunctatum BOETTGER, Zeitschr. f. Naturw., LVIII, 1885, p. 240 BOULENGER, Ann. & Magaz. Nat. Hist., (6) XIII, 1894. p. 347. Genera! appearance Eng y sto ma-like. Head small. Snout subacuminate, moderately projecting, once and a half the diameter of the eye. f^s^ril close to the tip of the snout, from the anterior corner of the orbit in a distance equal to the diameter of the latter. Frenal region slightly oconcave. Interorbitale space three times or a little more as broad tlia nlie upper eyelid. Fore limb much longer than its distance from the tip of the snout. Fingers moderately elongate ; first much shorter than second, the latter equal with the fourth. Hind limb stout ; the tibio-tarsal articulation reaches the shoulder. Toes without any web, the tips blunt; subarticular tubercles slightly prominent; inner metatarsal tubercle oval, distinct, the outer absent. Fifth toe much shorter than third. Skin smooth, along the middle line of the head a slight furrow. Dark chestnut-brown above with many white spots on the back and limbs ; on the snout a A-like white marking, on the upper eyelid some white spots top of the head without spots (Pl.
