Thanks to the kindness of Dr. Chapman, Chairman of the Board 

 of Curators of the Museum of the Academy of Sciences of Phila- 

 delphia, I have been able to examine the type specimen from the 

 Gaboon, preserved in that Institution, and compare it with two 

 specimens, male and female, collected by Mr. Bates on the Benito 

 River. 



Tongue with a free conical papilla in the middle. Head rather 

 large, as long as broad ; snout obtusely pointed, with feeble canthus 

 and concave loreal region; interorbital space narrower than the 

 upper eyelid ; tympanum distinct, two-thirds the diameter of the 

 eye. Pingers and toes moderate, the tips swollen into small disks ; 

 first finger not extending beyond second; toes with a short 

 but very distinct web ; two metatarsal tubercles, inner oval, outer 

 round, subconical ; a small tubercle on the tarsus, near the inner

 on each side of the scapular region. Dark brown above ; limbs
