but sligbtly posteriorly. Head narrow, but little wider tbau body, not 

 depressed; greatest widtli contained one and a half times in distance 

 from snout to gular fold. Body cylindrical, elongate, measuring ovcf 

 three and one-half times the distance from snout to gular fold. Fingers 

 and toes short, not webbed at base. Tail cylindrical, shorter than head 

 and body, and of almost the same diameter of body for three-fourths of its 

 length, then tapering- rapidly to a blunt i)oint. Skin not wrinkled, but 

 very closely pitted, the pits, beneath the lens, resembling circular scales. 

 Gular fold distinct. Twelve costal grooves. Color uniform brown; the 

 center of the dermal ])its on dorsal surface of })ody and ventral surface 

 of tail yellow, giving those regions the appearance of having been 

 sprinkled with yellow dust. This appearance may be due to the action 

 of alcohol. 



Measurements: Total length, 85""^; snout to cloaca, 46'"'" ; snout to 

 gular fold, 10"""; width of head, 6§"""; length of fore limb, 10'""'; of 

 hind limb, 11'""'; of tail, 39"""; distance from axil to groin, 31""". 



From S. Je^rrosHs Co^ie, this species may be known by the straighter 

 palatine teeth; the less divergence of the parasi)henoids ; the narrower 

 head; the proportionally more elongate body; the un webbed toes, and 

 the shorter and much stouter tail.

BUFO Laurenti, 1768. 



Bufo interniedius (iiiutber. 



Houlengcr, Cat. Ratr. Sal. Brit. Mus., 1882,307. 



A single specimen of Bufo, taken from the gutter in a street of the 

 city of Orizaba, varies from the description given by Boulenger, loc. cit., 

 as follows: The hind limb is longer, as, being carried forward along the 

 body, the tarso-metatarsal articulation reaches the anterior border of 

 orbit, instead of "to the eye." The color of interniedius is given as 

 "olive above, with irregular, sometimes confluent, dark spots; belly 

 immaculate or with slight spots." The specimen in hand is dark olive 

 above, with a narrow ash gray (white in life), dorsal line extending from 

 snout to anus. On top of the head this line widens, forming an ashen 

 cross-band which extends across the anterior half of eyelids and the 

 intervening frontal space. Sides and belly white with numerous small 

 dark spots. Limbs with many large olive spots ; front ones immaculate 

 beneath. Length, 42'"'".
