below with broad transverse scales; tubercles on front legs 

 smaller than those on hind legs ; scales on chin and throat small, 

 those on abdomen imbricate and very much larger; 8 lamellae 

 under longest toe; adpressed hind leg reaches beyond the elbow 

 of adpressed foreleg; distance of ear opening and nostril from 

 the ear, equal. 



Color in formalin. — Ground color drab-gray with a few scat- 

 tered brown spots; an elongate dark spot behind the eye; snout 

 with scattered brown spots; below immaculate. 



Measurements. — Total length (tail mutilated), 60 millimeters; 

 snout to vent, 50; foreleg, 18; hind leg, 24; width of head, 11. 



Remarks. — The type specimen was obtained from the Manila 

 High School where it was being used for dissection. The 

 abdomen has been opened and the end of the tail lost ; otherwise 

 the body is in good condition. There are no pores present, but 

 a series of 12 differentiated preanal scales on each side probably 

 indicates the number of pores in the male. This form is easily 

 distinguished from H. frenatus by the longer inner toe, with 

 the claw not sessile, the 8 rows of spiny tubercles on the tail, the 

 narrowed neck, and the increased number and size of tubercles 

 on the back. From H. depressus it differs in having the snout 

 twice the diameter of the eye; the ear opening vertical and less 

 than one third the diameter of the eye; the tail not depressed, 

 with angular lateral edge. No other specimen having these 

 characteristics has been seen. The type specimen was taken in 

 Manila by a student of the High School. 



Ptychozoon intermedia sp. nov. 



Diagnosis. — Large scales of the dermal lobe on the side of 

 the head equal to, or slightly smaller than, the largest abdominal 

 scales; back with from 10 to 12 irregular longitudinal rows of 

 flat round tubercles; tail with a narrow unsegmented terminal 

 flap, no wider than the nearest lobes, slightly notched behind; 

 annulations on the tail marked by lateral lobes directed some- 

 what backward, and a series of 4 or more enlarged scales above, 

 much larger than the scales on the lateral lobes. 



Type. — No. 1776, Bureau of Science collection ; Bunauan, Agu- 

 san Province, Mindanao, July 12, 1912; E. H. Taylor, collector. 



Description. — Rostral large, rectangular, with a triangular 

 depression in the upper part; the nostril is surrounded by the 

 rostral, the first labial, 2 postnasals, and a rather large supra- 

 nasal ; latter is distinctly triangular and forms a suture with its 

 mate behind the rostral; a large scale lies partly between the
