RANINAE 247 



men shows the following measurements. Total length 6*5 cm. 

 or 2|- inches, not 4 inches. 



Area covered by one fully-expanded hand 3'4 square cm. 



foot 6'0 



9 -4 square cm. 



i.e. for the four limbs 18 '8 square cm. = about 3 square inches, 

 and not 78 square cm. or 12 square inches. By some un- 

 fortunate oversight Wallace must have mixed up the total 

 expanded area with that of the four hands and feet ! In Brehm's 

 Thierleben the 78 square cm. have increased to 81 cm., and the 

 artist has in the somewhat larger species Eli. reinwardti improved 

 upon this, and has produced a truly startling picture by a further 

 exaggeration based upon the figure given by Wallace. 



Rli. reinwardti lives in the forests of the mountains of Java 

 and Sumatra. It reaches 3 inches in length, and is grass-green 

 above, yellow below. Younger specimens are further adorned 

 with large blue patches on the webs of the hands and feet and 

 behind the armpits. Besides the flap on the heel and the 

 curious cutaneous fringe on the forearm, suggestive of an in- 

 cipient flying-membrane, the skin forms a projecting fringe on 

 the inner side of the fifth toe and a transverse flap above the 

 vent. 



Of Rli. leucomystax, Annandale, who accompanied the Skeat 

 Expedition to Malacca, gives the following account : " This frog, 

 which is called by the Malays of Lower Siam either ' Berkata 

 Pisang ' (banana-frog) or ' Berkata Ehumah ' (house-frog), lays 

 its eggs either on leaves of branches overhanging the water, 

 or on the mud surrounding buffalo -wallows. The ova are en- 

 closed in a round mass of yellow froth, which afterwards becomes 

 steel-grey, about as large as a cricket-ball. Should they be 

 placed judiciously in a position sheltered from the sun, the 

 tadpoles may either hatch, and reach a considerable degree of 

 development, before the mass is washed into the water, or the 

 froth may be melted almost as soon as it is formed and the eggs 

 be carried into a pool by a shower of rain. Very often, how- 

 ever, the whole mass is dried up by the heat of the sun before 

 the rain comes. During the breeding season, which seems to 

 occur as often as the land is flooded under the trees, for I have 

 never seen the eggs of this frog 011 the bank of a river, the
