 side of which it reappears aud is continued ou the base of the tail. 

 These light streaks may lie broken up iuto regular series of spots, 

 either ou the back aud sides or only on the sides, where they may be 

 separated by narrow blackish bars ; series of black spots may run 

 betweeu them, as well as a series of blue, black-edged ocelli between 

 the two lateral streaks, or they may be crossed on the back aud sides 

 by more or less regular, straight or wavy Ijlackish bars. Very fre- 

 quently there is a dark brown or black vertebral streak, extending 

 from the occiput to the liase of the tail, or disappearing or broken up 

 into a series of spots on the posterior part of the body. In other speci- 

 mens there is no trace of either light or dark longitudinal streaks, aud 

 the back is irregularly spotted or reticulated with brown or black, aud 

 the sides of the head, neck aud body are barred with black and white 

 or bluish grey. A dark baud usually runs along the side of the tail. 



The following description of fresh specimens of the typical form 

 from the African littoral of the Red Sea is given by Anderson : 



" Olive-brown above, variegated with reddish brown. A rich, dark 

 brown, narrow vertebral line from the occiput to the base of the tail, 

 and three rich reddish longitudiual, but more or less interrupted 

 bands external to it, marked at intervals with brown spots and 

 forming vertical brownish bars ou the sides of the body and neck, 

 enclosing bluish and yellow interspaces, which assume the form of 

 ocelli. Sides of the head also more or less marked with vertical bars, 

 and likewise the upper labials. Sides of the tail yellowish, with a 

 dusky longitudinal band., Under surfaces white. Males much more 

 brilliantly coloured than the females."

 erythronota of Lacerfa ayilis.
