the body and limbs, greyer to sepia-brown on the head ; a patch 

 of lighter yellow across loins. Iris golden brown ; lower eyelid 

 veined with gold." 



It is characteristic of this species to possess a rudiment of 

 poUex appearing as a small tubercle in females and a larger 

 tubercle in males. In the male sent by Dr. Spurrell, this pollex 

 projects externally as a long sharp bony spine at right angles to 

 the metacarpal of the inner finger and piercing the skin ; whether 

 this is due to the desiccation of the specimen, or occasionally 

 happens during life as in the case of the pollex of Rana holsti or 

 of the ends of the ribs in the Pleurodele Newt, I cannot say.

9, Hyla baudinii Daud. 



When taken out of a dark hole these frogs are brown above, 

 usually with a metallic-green streak along the upper lip. After 

 exposure to light the colour changes to light yellowish grey, with 

 small green spots on the back and bars on the hind limbs. One 

 of the specimens, a female, is remarkable for the longer hind 

 limbs, the tibio-tarsal articulation reaching beyond the tip of 

 the snout. 



These frogs were pairing on the 31st May. 



Larvae, at different stages of development, agree in essential 

 characters with those of H. arhorea : position of eyes, spiraculum 

 and vent, shape of tail, structure of the mouth and lijos. Three 

 long series of teeth in each lip, the third of the upper lip inter- 

 rupted, the others continuous; beak broadly edged with black. 

 Total length 60 mm.; body 21; width of body 13; tail 39; 

 depth of tail 16. 



10. Agalychnis calcarifer Blgr. (PI. CII. fig. 2.) 



Described in 1902 from a single specimen from the Rio 

 Durango, N.W. Ecuador, 350 feet. 



The only example obtained by Dr. Spurrell is described in his 

 notes as brilliant sage-green above, flanks and upper surface of 

 thighs (with the exception of a narrow green streak) rich orange- 

 yellow with black bars ; hands and feet and lower parts orange-
