AND BATEACHIANS OE THE SOLOMON ISLANDS. 49 



canthus rostralis is angular, and very slightly curved ; the loreal region is oblique, and 

 not distinctly concave. The eye is of moderate size, and the interorbital space is plane, 

 and equals in width the upper eyelid. The tympanum, which is perfectly distinct and 

 circular, measures two fifths the diameter of the eye, and a little less than the distance 

 which separates it from the orbit. 



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

 moderate, with slightly dilated tips, and with large round subarticular tubercles ; the 

 first finger is distinctly longer than the second, slightly longer than the fourth, and a 

 little shorter than the third. The metacarpal tubercles are three in number, the inner 

 being the largest and the most distinct. The hind limb is strong and long, the tibio- 

 tarsal articulation reaching as far as the tip of the snout, and the tibia being nearly as 

 long as the fore limb. The toes are moderately elongate, and nearly entirely webbed, 

 and the tips are dilated into small regular disks ; the free edge of the web is strongly 

 curved, and reaches the disks of all the toes ; the subarticular tubercles are large and 

 oval. The inner metatarsal tubercle is elliptical and flattened, and there is a second 

 tubercle, at the base of the fourth toe, which is smaller, roundish, and less distinct. 



The upper surfaces are vermiculated with very small glandules, which are intermixed 

 with larger ones on the posterior half of the upper eyelid ; a few elongate warts on each 

 side of the foremost part of the back show an indication of the lateral glandular fold 

 of other species of Eana. A strong glandular temporal fold runs obliquely from the 

 eye, above the tympanum, towards the shoulder. The lower surfaces are perfectly 

 smooth. 



The upper parts are uniform blackish olive, with small greyish marblings on the 

 thighs. The lower surfaces are whitish, the throat slightly mottled with greyish.

A single female specimen, collected by Mr. Guppy on the Shortland Islands. 



Except the Bull -Frog of North America, no other Uana is known to attain so great 

 a size as this. The nearest ally of R. gujppyi appears to be M. grunniens, Daud., which 

 occurs in Amboyna and Java, but in that species the series of vomerine teeth are 

 oblique, the tympanum is larger, the digital disks are smaller, there is a tarsal fold, 

 and no outer metatarsal tubercle, and the hind limb is shorter.
