HERPETOLOGY OF PORTO RICO. 



595 



Several specimens (26958-62) taken at an altitude of about 2,978 

 feet near the top of El Yunque Mountain, February 24-26, were essen- 

 tially like the above, to the description of which may l>c added that 

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

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

 gest specimen in this lot has the throat strongl} r suffused with gam- 

 boge-yellow. 



This species seems to be as remarkable for the stability of its color- 

 ation as /:'. aurieulatus is for the reverse. 



Remarks. — -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 JbJeutherodactylus lentus (Cope), from which 

 it differs 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 larger. The coloration also is different and remark- 

 ably constant. 



Hi (hi tat. — 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.
