Dendrobate8 tinctorius (Schneider). 



Holanda Farm. 



Agalyohius helenae Cope. 



Cartago. Dr. Calvert gives the following note: 



"There was an exceedingly handsome frog here, one of which we 

 took to the hotel and kept for some days. When "asleep" its body,, 

 exclusive of legs, is 63 mm. (2h ins.) long. Ordinarily the upper 

 surface of body and legs is a bright pea-green, below the body is 

 speckled white and reddish-brown, with a band of brilliant beautiful 

 blue on each side of the abdomen. We photographed it as we noticed 

 great color changes. When first caught it was pale green. When 

 we took it out of the vasculum at the hotel it was a dark dirty green 

 with pale spots on the back. While we photographed it, it grew 

 light again with paler spots over the back. After night-fall it was 

 again very dark, but although it spent the night in a dark cupboard 

 it was pale green when we first looked at it in the morning and again 

 at 4.30 P.M. When caught it secreted a quantity of sticky mucus 

 having a powerful and disagreeable odor, which it was difficult to 

 remove from the hands. It was able to cling without other support 

 than its toes on the vertical side of our glass graduate. The tips 

 of all the toes (4 on front, 5 on hind feet) are expanded into large 

 fleshy disks with which the frog climbs."

During November of 1913, Mr. C. F. Derby made a small collection 

 in the Rio Jaguribe at Barro Alto, in the municipality of Igatu, and 

 about 413 kilometers due south from Fortaleza. When the fishes 

 were captured the water in the river was a trifle salty, owing to a 

 very light rainy season the year before.
