Remarks. — The type of H. brieni is somewhat dried up, so that the 

 reconstructed drawing of it which accompanies deWitte's description 

 does not give the true body shape. The head is too short in the draw- 

 ing, even allowing for perspective; the distance from a line between 

 the posterior corner of eyes to tip of snout is less than one-fifth the 

 total head and body length in the drawing, but in the specimen itself 

 it is more than one-quarter the total length. 



This species is to be found on wooded mountain ranges, and fre- 

 quents bromeliads and tree holes at night. Its voice is an interrupted, 

 staccato series of short, sharp trills, very high in pitch, that may be 

 imitated by whistling pe-pe, pe-pe into a glass vial. No eggs are 

 known, but the larvae have been found in very cold running water, 

 and may be taken \vith a dip net along with adults. The tadpoles are 

 a beautiful golden color with markings on the tail, and have funnel- 

 mouths to fasten onto the stones in swift currents. The adults are 

 never found in tall trees, but sometimes may be found in arboreal 

 ferns overhanging the water or near it.

Descrivtion. — Adult female, USNM 121636 (paratype), Petrdpolis, 

 Rio de Janeiro. Vomerine teeth in two sm.all transverse, well- 

 separated patches between the choanae; tongue about three-fourths 

 as wide as mouth-opening, broadly oval, very slightly concave on its 

 free posterior border; snout moderately elongate, its tip truncate 

 when viewed from above and in profile, the upper jaw extending 

 considerably beyond the lower; nostrils more lateral than superior, 

 the flesh around them projecting and anteriorly forming a pair of 

 broadly conical projections, the tip of the snout between these pro- 

 jections appearing concave; distance of nostrils from end of snout 

 about one-fifth that from eye, separated from each other by an interval 

 equal to two-thirds their distance from eye. Canthus rostralis pro- 

 nounced; loreal region slightly concave and flaring widely to the upper 

 jaw. Eye very large and prominent, its diameter nearly equal to 

 its distance from tip of snout; interorbital diameter about 1% times
