102 LIZARDS OF THE PHILIPPINE ISLANDS 



femoral scales, thirteen or fourteen in number, which probably 

 represent the number of preanal and femoral pores in the male ; 

 a large scale on each side of tail behind anus ; diameter of eye 

 equals its distance from ear, but is less than distance from 

 nostril; a depression behind nostril. 



Color in life, — A soft olive gray above with touches of bluish 

 and brown ; body traversed by several wavy lines of dark brown. 

 Head more or less flecked with brown; a broad brown band, 

 from eye to shoulder; tail marbled variously with brown; legs 

 indistinctly barred with reddish brown bands ; below cream with 

 large, indistinct darker spots under tail.

Remarks. — This species seems to be a form rather inter- 

 mediate between the two known species of the genus. From 

 Ptychozoon kuhli it differs in the absence of the wide flap at 

 the extremity of the tail, the very different character of the 

 lateral lobes on the tail, and the much larger number of tubercles 

 on the body; perhaps also in the presence of femoral pores. 

 From P. horsfieldii it differs in having the body granules inter- 

 mixed with numerous flat tubercles and broad transverse plates 

 below the tail except on the outer tip. A comparison of the 

 descriptions will reveal other differences. 



Only the type specimen was found; it was captured about 

 ten o'clock in the morning on the buttress of a large naga tree, 

 near the small Manobo village of Bunawan on Simulao River. 

 When disturbed the animal jumped to the earth amid a mass 

 of leaves and bark and was practically indistinguishable from 

 its surroundings.

 homalocephalum came from the Riu Kiu Islands. He has exam-
