the shoulder, and some larger glandules along the sides; venter smooth 

 except for transverse ridges across middle of belly and coarse granules 

 on posterior and lower surfaces of femur; some low glands along side 

 of belly behind axilla; a pronounced glandular ridge from posterior 

 corner of eye above tympanum, ending just above the large gland at 

 mouth commissure; no skinfold across chest; no ventral disk; a pair 

 of lateral external vocal sacs in the male. 



Dimensions. — Head and body, 44 mm.; head length, 15.5 mm.; 

 head width, 15 mm.; femur, 18.5 mm.; tibia, 20.5 mm.; foot, 22 

 mm.; hand, 11.5 mm. 



Color in alcohol. — Dorsum sepia; a pale drab crossbar between the 

 eyes, outlined by narrow darker lines; snout in front of these darker 

 lines pale olive; a small oval olive spot in center of back between the 

 shoulders; upper limb surfaces light sepia to drab, with three indistinct, 

 slightly darker crossbars that are much broken up on the upper 

 femur and foot; similar but very indistinct bars on arms. Sides of 

 body olive buff with small gray punctulations, the lateral glands 

 clove brown. Venter pale buff, with a very fine drab reticulation over 

 throat and part of chest; lower limb surfaces also spotted or reticulated 

 with drab. Side of head drab, with a paler vertical line at tip of snout 

 and three or four diagonal light lines along the tip separating the 

 dark area into squarish or rhomboidal spots. Posterior femur below 

 the crossbars (already mentioned) has the lower half clove brown, 

 with a buff line from near each side of vent in a slightly diagonal 

 direction to back of knee. Anterior femur olive-buff with faint gray 

 marblings on upper part, immaculate below. Gland at mouth com- 

 missure and glands from axilla nearly to groin, ochre yellow. Posterior 

 femoral glands (on each side of anus) clove brown. 



Remarks.— Two half-grown frogs (USNM 103621-2, from Mana- 

 capurti, Amazonas, Brazil) that measure 31 and 25.5 millimeters, 

 respectively, already show the yellow coloring on the large gland 

 behind the mouth commissure and on the glands along the sides of 

 the belly. It is possible that these two specimens are cotypes of L. 

 intermedins A. Lutz, as they were given to the United States National 

 Museum by Dr. Lutz in 1935, having been collected by William 

 Erhardt on June 24, 1925, and September 7, 1924. It is apparent 

 that these specimens are not adults as Dr. Lutz thought. 



The largest male at hand (USNM 146252) measures 50 millimeters, 

 a length that is approached by a female (USNM 142187) measuring 

 48.5 millimeters. 



The light stripe on the posterior femur is distinct, although some- 

 times irregular, in about two-thirds of the 20 examples examined; 

 it is indistinct or absent in the others. The tarsus is smooth in 14 of 

 the specimens, faintly granular in four, and pustular in two.
