From 

 Atelopus seminiferus, sp. nov. 



Body elongate, limbs rather short ; the muzzle nearly reaching 

 the middle of the extended forearm, and the heel marking the 

 scapula. The muzzle viewed from above is rounded, truncate, 

 and in profile somewhat prominent; the nostril marking a line 

 which falls behind the sj^mphysis of the mandible. The eyelid is 

 thickened, and is not prominent; and the diameter of the eye 

 equals the length of the muzzle and the posterior interorbital 

 width. The ethmoid appears to be ossified to the end of the 

 muzzle. Fingers slightly, toes largely webbed, the web reaching 

 the end of the first phalange of the fourth (long) toe. Tongue 

 narrow, extensively free ; ostia pharyngea smaller than the small 

 choanse. Skin smooth except on the sides, where there are 

 numerous closel3'-placed minute tubercles from the head to the 

 groin. A broad fold of skin extending from the side to the middle 

 of the length of the femur. 



Above, dark-brown ; below, brownish-oraiige. Sides black from 

 head to groin; each tubercle of the skin yellow, resembling yellow 

 grains. Limbs uniform black.
