Notes on Paratypes 



In structural character? the twelve paratypes agree closely with the 

 type. Two specimens are light gray, instead of brown, with only indica- 

 tions of the black spots; in most specimens the postocular dark streak is 

 broken up into a series of spots ; one specimen is light brownish gray on 

 each side, the area between sharply darker; the bars on the legs are dis- 

 tinct in all specimens. 



The plaintive, diminuendo note of this small species is one of the 

 most characteristic sounds in the amphibian chorus of the Luquillo forest. 

 Its song consists of a series of six or eight whistled notes, each slightly 

 louder in pitch and a little fainter than the last. It sings habitually on 

 the ground or in the lowermost leaves of plants. It is particularly diffi- 

 cult to locate its position from its song, partly because it is usually well 

 concealed, partly on account of the peculiar ventriloquy of its voice. 



Eleutherodactylus richmondi Stejneger 



•Eleven specimens of tin's species were collected at El Yunque, between 

 the Forester's cabin and the peak. This species is probably distributed 

 throughout the virgin forest of the Luquillo Reserve. It should he looker! 

 for in the high forest south of Jayuva. Its relations with E. lentus of 

 St. Thomas and E. weinlandi of Hispaniola add to the evidence of former 

 land connections of the Virgin Islands and Hispaniola with Porto Rico. 



Like the larger series examined by Stejneger, the present specimens 

 are extremely uniform in structural characters and in coloration. The 

 only variation noted is the occasional lightening of the chestnut color 

 of the dorsal area between the light dorsolateral lines. The proportions
