Coloration of i;rmf/spemmens.~U.S.^.M. No. 271J:8(L. S. No. 9058). 

 Iris pale brassy, sprinkled with l)lack. General color above dull clay- 

 colored with a strong olive wash; blackish brown markings and an ill- 

 defined hourglass-shaped mark between shoulders; also a larger black- 

 ish spot on each side of the coccyx, which is marked by a pale streak; 

 indications of blackish cross bands on legs; underside dirty white, 

 becoming Hesh-colored behind and strongly reddish flesh color on 

 underside of fenmr and nearest portion of bell}^; tips of toes dark 

 brown; tips of warts on back black, those between shoulders particu- 

 larly large. 



Another specimen (No. 271-1:9) was colored as follows: Upper side 

 olive, strongly suffused with "gallstone yellow,*" which is particularly 

 noticeable over the insertion of the fore limbs; very few traces of 

 dusky markings, but the pustules are black, especially anteriorly; an 

 intensely ochraceous-rufous spot on the middle of the back; on the 

 underside the yellow suffusion invades the white ground-color on 

 the portion nearest to the flanks. 



The third large specimen (No. 27150) was quite similar to the last, 

 though without any rufous spot on the back, which seems to be an 

 anomaly. Whole upper surface darker olive, and flanks, including 

 space at base of fore liml) and l)elow the ear, more intenseh' and more 

 well-defined yellow; underside dirty yellowish white. 



A young specimen (No. 27151) was colored as follows: General color 

 above drab, more isabella-colored on head; dark markings blackish, 

 those on shoulders pale-edged externally; flanks with a purplish suffu- 

 sion and indications of a broad longitudinal band, well-defined and 

 pale-edged above, l)ut gradually fading below into the pale Isabella 

 color of the bell}^; underside with a network of coarse dark-grav mot- 

 tlings and marblings. 



Habitat. — The toad seems to be somewhat rare in Porto Rico, pos- 

 sibly because of lack of suitable localities. Dr. Stahl informed me
