AND BATEACHIANS OF THE SOLOMON ISLANDS. 55 



the orbit ; the canthus rostralis is distinct, obtuse, and straight ; the loreal region is 

 oblique and concave ; the nostril is much nearer the tip of the snout than the orbit. 

 The eye is very large and prominent ; the interorbital space has a slight median ridge 

 or keel, and its width equals about three fourths that of the upper eyelid. The 

 tympanum is round and very distinct; its diameter equals about half that of the orbit ; 

 the distance that separates it from the latter is two fifths or half its diameter. 



The fore limb stretched backwards reaches as far as the vent. The fingers are 

 moderately long, slender, cylindrical, with the tips not dilated but simply swollen ; the 

 subarticular tubercles are remarkably strong and prominent ; the inner finger is as long 

 as the third and much longer than the second, which equals the fourth. Three oval 

 metacarpal tubercles are very distinct. When the hind limb is stretched forwards, the 

 tibio-tarsal articulation reaches the centre or the anterior border of the eye. The toes 

 are moderately elongate, slender, cylindrical, free, with a very slight rudiment of web at 

 the base ; there are no lateral dermal margins, and the tips are swollen like the tips of 

 the fingers ; the subarticular tubercles are extremely strong and prominent, and sub- 

 conical. There are two very prominent tubercles on the metatarsus, an oval inner and 

 a rounded, smaller, outer. 



The skin of the back and flanks is more or less corrugated and with irregularly 

 scattered short longitudinal glandular folds, which are shorter and less regular than in 

 Cornufer corrugatus, A. Dum. ; a prominent narrow oblique fold runs from the eye to 

 the shoulder, passing above the tympanum. The lower parts are smooth, except the 

 lower belly and the lower surface of the thighs, which are feebly granulate. 



The colour of the upper parts is a grey-brown or purplish brown ; the tympanum is 

 chestnut-brown ; on the sides of the head are more or less distinct vertical darker bars, 

 and the cross bars on the limbs also vary in intensity. The lower surfaces are whitish, 

 the throat more or less crowded with brown mottlings, with a series of round lighter 

 spots round the lower lip. 



The male with two internal vocal sacs. 



One of the females has the oviducts distended with ripe ova. As in the other species 

 of the same genus, the ova are enormous compared to the size of the animal, and there 

 is every reason to believe that the young undergo the metamorphoses within the egg. 

 In a specimen measuring 73 millim. from snout to vent the diameter of a ripe ovum 

 is 5 millim. ^. 5 .
