than long, scarcely in contact with the rostral; prefrontals in con- 

 tact, forming a suture about % length of fronto-nasal ; fronto-nasal 

 divided on its posterior % by a. groove in line with prefrontal suture ; 

 width of frontal 1.6 in its length, its length greater than its distance 

 from the tip of snout ; parietals forming a suture behind parietal ; 

 fronto-parietal suture equals length of prefrontal suture; a single 

 narrow shield in front of ear opening. 



Color uniform brown above, yellowish beneath. 



Mabuia brevicollis (Wiegman). 



Voi. Two specimens. Body 120 mm., tail 175 mm.; body 127 

 mm., tail missing. 



Color brown, the edges of the scales are darker, forming dark lines 

 along the rows of scales. A few white spots on lower portion of sides 

 of the neck ; ventral surface of head and region about the groin dark 

 blue, the rest yellowish; 32 scales around the middle of the body; 

 fingers and toes overlap when the limbs are appressed. 



Lukenya. Two specimens. Body 121 mm., tail missing; body 

 100 mm., tail 122 mm. 



In both of these specimens the lines along the rows of scales are 

 well denned. Narrow dark bands on sides extending across back ; in 

 these are many white spots. On the larger specimen are 4 bands be- 

 tween ear and arm, 8 between arm and leg; ventral surface light, the 

 throat black spotted, a few scattered spots on sides of belly. The 

 smaller specimen resembles the larger except the bars across back 

 are less prominent; these bands extend on tail. The general color 

 of these two specimens much resembles that of Cholcides ocellatus. 



Athi River. One specimen. Body 128 mm., tail 150 mm. 



Color much lighter than the preceding, the stripes along the rows 

 of scales evident but not conspicuous; ventral surface light, the throat 

 bluish; no distinct white spots nor dark bars anywhere; toes and 

 fingers scarcely meet when the limbs are appressed. 



Mabuia quinquetseniata (Licht.). 



Voi. All of the specimens of this species in the collection were 

 taken at this place. Six of the specimens have the median dorsal 

 and the two lateral bands well developed, the body with very 

 few of no white spots or dots. These specimens measure as follows: 

 Body 37 mm., tail broken; body 51 mm., tail 76 mm.; body 59 mm., 

 tail broken; body 57 mm., tail broken; body 88 mm., tail 95 mm.; 

 body 85 mm., tail broken. Three specimens have faint light dorsal
