ferred to the genus Leptodactylus on the basis of our present 

 knowledge, it must be by enlarging the conception of the genus 

 to include both those forms which have simple phalanges in 

 the adult form and those which have at least as T-shaped pha- 

 langes in the mature stages as the young of the species now 

 referred to the genus. 



The writer believes the conclusion of Peracca"', that the 

 species represents a genus. distinct from Leptodactylus and 

 Eleutherodactylus and allied to Plectromantis, is more nearly 

 correct. It dififers from Eleutherodactylus in the shoulder 

 girdle, from Leptodactylus in having T-shaped phalanges in 

 the adult stage, and from Plectromantis in the absence of true 

 pads. It is thus apparently closest to Plectromantis, and it is 

 j'Ossible that a study of the phalanges of the latter may reveal 

 tliat the genera are not to be separated. It is possible also 

 that the species constituting the genus l^lectromantis are to be 

 referred to Leptodactylus, as Boulenger has suggested, and 

 in this case it will be necessary to determine if the phalanges 

 change to the same extent as in the species now referrea to 

 Lei)todactylus or from the distinctly T-shaped, as in young 

 Uncatiis, to the simple type, to decide whether or not lincatiis 

 goes with them. 



The specimen obtained is immature, measuring 28.5 mm. in 

 total length. The ground color of the back and sides, includ- 

 ing the hea.d, black ; the mimerous punctulations olive gray; the 

 lateral stripes primuline yellow ; an irregular spot of flame 

 scarlet in the region of the groin extending on the thigh ; fore 

 limbs olive gray with black markings ; the posterior limbs dark 

 olive gray to the feet, the feet olive gray, the bands black; 

 two large spots beneath the tibia and several on posterior face 

 of femur flame scarlet ; chin, throat and chest deep neutral
