7. Hyla aruensis n. s. 



Snout oval , a little longer than the diameter of the 

 eye ; canthus rostralis distinct ; loreal region oblique , 

 slightly concave; nostrils near the tip of the snout; iu- 

 terorbital space about twice as broad as the upper eyehd; 

 tympanum rather indistinct , somewhat more than one half 

 the diameter of the eye; an indistinct fold along its up- 

 per border. Tongue oval , slightly notched behind ; vo- 

 merine teeth in two oblique divergent groups between the 

 choanae. The three outer fingers for two thirds webbed; 

 toes webbed till the disks , except the fourth ; disks about 

 as large as the tympanum. Hind limb being carried for- 

 wards along the body, the heel reaches beyond the tip 

 of the snout. Skin smooth above , belly and underside of 

 thighs granulate. 



Colour : (spirit-specimens) above uniformly blue , under- 

 side yellowish; a white streak along the outer edge of the 

 fore-arm and the uuder-leg. 



Length from snout to vent 42 m.m. 



Two specimens from the Aroe-Islauds collected by von 

 Rosenberg, one from Misool by Hoedt. 



Closely allied to H. dolichopsis Cope, who however 

 differs from our species by its distinct , strong fold from the 

 eye to the shoulder; by the transverse position of the vo- 

 merine teeth and choanae; by the areolate structure of 

 the skin on the sides of the body; and by its characte- 

 ristic coloration.
