LEIOLOPISMA 209 



or opaque disk ; tympanum distinct ; no supranasals ; rostral 

 usually forming a suture vath the frontonasal; frontal not 

 broader than the supraocular region; one or more pairs of en- 

 larged nuchals. 



This genus does not differ widely from the genus Siaphos; and 

 two species here described, Siaphos auriculatum Taylor and Sia- 

 phos kempi Taylor, rather join the two groups. Siaphos is 

 usually characterized by the more-reduced limbs, the minute ear, 

 and the very small, or absent, prefrontal. In S. auriculatum the 

 ear is large, the prefrontals are wanting, and the legs are moder- 

 ate. In S. kempi the prefrontals are fairly large, the limbs 

 barely meet, and the ear is well developed. Superficially they 

 resemble each other, especially in color and markings. It is 

 highly probable that other intermediate species are present in 

 the Islands.

Description of species. — (Described from thirteen specimens 

 from E. H. Taylor collection; collected at Bunawan, Agusan, 

 Mindanao, 1912-1913, by E. H. Taylor.) Body rather slender, 

 with a long pointed snout; rostral large, covering entire point 

 of snout, which is very much flattened ; no supranasals ; fronto- 

 nasal very large, about as broad as long, broadly in contact with 

 rostral and nasals and narrowly touching frontal (three spec- 

 imens have the frontal separated from frontonasal) ; prefrontals 

 present, quadrangular, usually separated, narrowly touching 

 both f renals, always in contact with the first supraoculars ; fron- 

 tal very elongate, at least equal to its distance from end of snout, 

 its anterior end farther forward than supraocular region, its
