FROGS OF COLOMBIA — COCHRAN AND GOIN 51 



are immaculate pale yellow or olive; often, however, some fine dark 

 spots occur on the chin, and sometimes dark dots extend over most 

 or all of the ventral surfaces. 



In femoralis, a species of about the same size that might be confused 

 with brunneus, the entire chin, chest, and anterior half of belly are solid 

 black, while dark spots on a light ground occur only on the posterior 

 half of the belly and on the lower surfaces of the limbs. P. boulengeri, 

 the other species with a dark-spotted venter, has much larger black 

 spots all over the lower surfaces, concentrating on the throat around 

 a light longitudinal median area with large, irregular black patches 

 on either side of it. 



P. brunneus resembles latinasus considerably in color and general 

 appearance, but its head is proportionately a little shorter and narrow- 

 er, its foot is much longer, and its hand is slightly longer. Also, brun- 

 neus apparently is larger. 



The white (yellow in life) stripe that starts behind the eye (or 

 sometimes on the canthus) in brunneus begins to curve downward when 

 it reaches the sacrum and goes diagonally across the dark lateral stripe 

 to the anterior surface of the femur, often enlarging to a definite 

 light spot in the upper part of the groin. In latinasus this light line is 

 said to continue parallel to the dark stripe without crossing it — both 

 becoming diagonal on the side — and sometimes extends on the upper 

 proximal part of the femur as a light bar. Occasionally a thin light 

 stripe commences at the middle of the wide dark lateral stripe and 

 continues straight back to the groin, and sometimes a third light 

 stripe bounds the lower edge of the dark lateral stripe at the latero- 

 ventral area in latinasus. Such markings are absent or indefinite in 

 brunneus.
