HERPETOLOGY OF PORTO RICO. 



595 



Several specimens (26958-62) taken at an altitude of a])out 2,078 

 feet near the top of El Yunque Mountain, Februar}^ 24-26, were essen- 

 tially like the above, to the description of which may be added that 

 the brown color on the back becomes more of an Indian-red on sacrum 

 and femur, fading- to a clear rufous flesh-color on the heel. The lar- 

 gest specimen in this lot has the throat strongly sufi'used with gam- 

 boge-yellow. 



This species seems to be as remarka])le for the stability of its color- 

 ation as E. aariculat'iis is for the reverse. 



Remarl's. — The present species, which I take great pleasure in ded- 

 icating to Dr. Charles W. Richmond in grateful memory of cheerful 

 companionship in the native haunts of this interesting novelty, is appar- 

 ently nearest related to MeutherodaGfylus Jentas (Cope), from which 

 it difl'ers in many important points. Thus, the vomerine teeth are 

 placed much farther back from the interior nares, and the second finger 

 is considerably longer than the first instead of equaling- it in length; 

 there is no trace of a web between the toes and the outer metatarsal 

 tubercle is much larg-er. The coloration also is difi^erent and remark- 

 ably constant. 



Habitat. — This new species thus far has only been collected on El 

 Yunque Mountain, from an altitude of about 900 feet to near the top. 

 It was found on damp ground under stones and leaves.
