HERPETOLOGY OF PORTO RICO.

Whether Brocchi's Leptodactyhts ccdiginosm" really belongs here is 

 somewhat more doubtful. The figure does not much resemble this 

 species, nor does the description mention the conspicuous white labial 

 stripe. Bocourt's observation that the voice of the species collected 

 bj him at Isabal and at Pansos resembles the baying- of a dog and 

 may be rendered by the syllable rhouap! rhoua/p! is also at variance 

 with my own experience with Z. aTbtiabris in Porto Rico.
