 sometimes an indistinct ridge; inner metatarsal tubercle elliptic, 

 fairly prominent, one-fourth to one-half the length of inner toe; 

 no outer metatarsal tubercle; skin of back between dorso- 

 lateral glandular dermal folds either smooth, or with minute 

 hispid tubercles, or granular with small pearllike tubercles; a 

 strong glandular fold from upper eyelid to shoulder, and its 

 upper branch is continued backward as a narrow or moderately 

 broad dorso-lateral fold to about level of acetabulum or not 

 quite so far; a more or less distinct glandular fold, often inter- 

 rupted posteriorly, from below eye to above arm; longitudinal 

 or sinuous glandular ridges bearing numerous small hispid 

 tubercles on upper surface of thigh, tibia, and tarsus; under-

 times green in front and brown behind, uniform or with small
