FROGS AND JO ADS 



species of all is Guppy's frog (R. guppyi}, from the Solomon islands, 

 in which the length of the head and body is upward of nine inches. 

 The bullfrog is one of those species in which the tips of the toes are pointed, and it 

 is especially characterized by the web extending to the tip of the fourth toe of the 

 hind-foot, the large size of the aperture of the ear, and the relative length of the 

 hind-leg; the two latter characteristics distinguishing it from Montezuma's frog (R. 

 montezumce} of Mexico. The body has has no lateral glandular fold; and the vocal sacs 

 of the male are internal. In color the bullfrog is brown or olive above, with darker 

 marblings; the under parts being either uniformly colored, or marbled with brown. 

 In length it measures from seven to seven and one-half inches, exclusive of the legs. 

 More abundant in the southern than in the northern portion of its habitat, the bull-

frog is generally met with in rivers and streams well shaded with trees or bushes, 

 where it may be seen in numbers basking in the midday sun. Its croaking is said 

 to be louder than that of any other species, and can be heard for a distance of sev- 

 eral miles. In the Southern States of America, although most intense during the 

 spring and summer, the croaking is continued throughout the year; but in the north 

 it is confined to the spring and summer, being especially loud during the breeding 

 season. It is a remarkable fact that in Canada, at least, the bullfrog passes the 

 first winter in the larval condition, and takes two years to attain its full growth. 



It may be mentioned that the small Indian frogs forming the genus 

 Oxyglossus differ from the members of the preceding genus by the ab- 

 sence of any notch in the tongue, and the want of vomerine teeth. They are spe- 

 cially interesting on account of being represented by fossil species in the Eocene
