200 Frogs of the Okefinokee Swamp 



bluish or ash grey, fawn colour, or even salmon or red in tone." This applies 

 quite well to P. nigrita in its restricted sense except that we have not recorded 

 any salmon-red individuals yet, though they are possible. 



On August 5, 192 1, F. Harper came on one live frog which "was blackish- 

 olive, whitish below, and had a greenish-white maxillary streak. After a 

 couple of days of captivity in a can, its black back had changed to olive, 

 coarsely spotted with black." 



Variations in color. Back: Black, speckled with small white warts; middle 

 of back cinereous with an interrupted stripe of black. — LeConte 1825, Harlan 

 1825 and 1835. 



Back olive brown, with a tinge of yellow, and an interrupted black ver- 

 tebral line — Holbrook 1842. 



Color above dark slate, with more or less of oblong, oval or round some- 

 times very numerous black spots, which often form stripes. — LeConte 1855. 



Gray or greenish-black, with usually three longitudinal rows of black, 

 light-edged, roundish spots. Occasionally these spots fuse into bands. . . . 

 A narrow black band starts at the tip of the snout, runs through the eye, 

 covers the tympanum and ends at the shoulder or beyond — Deckert 1915. 



Blackish ash above, with three interrupted black longitudinal bands; 

 loreal and temporal regions black — Boulenger 1882. Color above leaden, with 

 three longitudinal rows of darker, light-edged spots, extending one on each 

 side, and one on the median line. These spots may be united into a band on 

 one or on both sides or on the middle hne. Cope 1889. 



Blackish ash, with three or five darker, sometimes interrupted longitudinal 

 bands; a black streak passing through the eye above the tympanum — Gun- 

 ther 1858. 



Belly. Beneath granulate whitish. — LeConte 1825. 

 Beneath whitish granulated. — Holbrook 1842. 

 Abdomen yellowish-white. — Holbrook 1842. 



Beneath whitish, sometimes tinged with yellow with a few black spots 

 assembled in groups cancellately reticulate. — LeConte 1855. 



Beneath white immaculate. — Boulenger 1882. 



Inferior surfaces yellowish. — Cope 1889. 



The under surfaces are greenish-yellow. — Deckert 191 5. 



General habits. To Deckert (191 5, p. 23) this is a shy species, extremely 

 difficult to catch. Holbrook (1842, Vol. IV, p. 108) holds ''But little is known 

 of the habits of Cystignathus nigritus; but, from the form of the posterior 

 extremities and the arrangement of the toes, it would seem to be a land 

 animal, and closely alhed with the Cystignathus ornatus." In general we 

 suspect it accords closely in habits with P. triseriata and P. feriarum. From 

 remarks and observations of O. C. Van Hyning at Gainesville, Florida, this is 

 quite likely true. 



VOICE 



"Its call is similar to that of the cricket 'frog,' but much louder, and the 

 crepitations are slower." (Deckert 1915, p. 23). In 1921 at Fargo, Ga., F. 

 Harper "During downpours on the afternoon of August 5, . . . began to hear
