NORTH AMERICAN BATRACHIA AND REPTILIA.

Since then, other specimens have been examined and carefully 
compared with some from Florida and Texas. These have con- 
vinced us that specific differences do not exist between them. By 
comparing the description with those above, it will be seen, 
however, to differ as widely from them as they do from each 
other; therefore, if they can be retained as subspecies, the 
specimens falling under the following description will naturally 
form a third subspecies for which we propose to retain the name 
formerly used specifically, that is, circulosa. 
67. R. areolata , subsp. circulosa. Above brownish- black, 
divided by very narrow lines of clay-color into circular and irreg- 
ular blotches, which are largest posteriorly; arms with dark 
blotches; legs with transverse bars; posterior face of thighs mot- 
tled; beneath white ; a few black spots along jaws; head broad, 
depressed ; snout very obtuse, not produced ; skin coarsely 
punctate above; a deep concavity between nostril and eye; 
diameter of tympanum and length of eye the same ; internal 
nares oblique; the vomerine patches of teeth arranged obliquely 
between them; region above and behind tympanum much 
swollen; a broad, cutaneous fold on sides of back, narrower 
behind; a similar one from eye to arms ; a third between these 
posteriorly; large oval tubercles on sides; hind surface and 
posterior half of under surface of thighs coarsely granulate ; 
lingers distinctly webbed at base; toes palmated only between 
first phalanges, the webs narrow and incised; L. three and 
forty-six hundredths inches; femur one and forty-two hun- 
dredths; tibia one and sixty-three hundredths; foot two and forty- 
five hundredths; arms one and eighty-five hundredths; width of 
head one and thirty-two hundredths; length of leg five and five- 
tenths inches. Description taken from an alcoholic specimen 
collected in Benton Co., Indiana, by Mr. E. F. Shipman. 
In the collection of the Smithsonian Institution, there are 
specimens bearing the specific name of A. areolata from Illinois 
(2), Texas (1), Florida (1), and Georgia (1). Those from 
Illinois, Florida, and Georgia have been labeled R. areolata 
capito , the other R. areolata areolata. The specimens from 
Illinois (northern portion) are in coloration like the one we have 
described above from Indiana, under the name of R. areolata 
circulosa. The Texas specimen is white below, above light 
brown with dark brown blotches, rounded on front portion of 
body and encircled by a narrow whitish line, more angular 
posteriorly; otherwise as in R. areolata circulosa. The Florida 
specimen is white below and yellowish or greenish above, and 
covered with rounded and more or less irregular brown spots;
