Fvogs and a new Snake from Formosa. 493 



brown or black ; lower parts white, throat sometimes 

 brownish. Male with an internal vocal sac on each side and 

 a very large tlat gland on each side of the body, above and 

 behind the shoulder, as in A. pleuraden. 



From snout to vent 55 mm. 



Several specimens iVom Fuhacho village, altitude about 

 40UO feet. 



Agrees very closely with li. pleuraden, BIgr., from Yunnan, 

 but differs in the distinctly dilated tips of the toes. 



liana sauteri. 



Vomerine teeth in two strong oblique series extending 

 considerably beyond the level of the posterior border of the 

 choante. Head moderate, as long as broad ; snout rounded, 

 not prominent, as long as the eye; canthus rostralis obtuse; 

 loieal region not very oblique, slightly concave ; nostril a 

 little nearer the end of the snout than the eye ; interorbital 

 region a little narrower than the upper eyelid; tympanum 

 very distinct, two-thirds to three-fourths the diameter of the 

 eye, narrowly separated from the latter. Fingers slender, 

 with distinctly swollen tips, first and second equal or first 

 extending very slightly beyond second ; toes slender, three- 

 fourths webbed, the tips dilated into small but distinct disks; 

 subarticular tubercles large and prominent ; a small oval 

 iinier metatarsal tubercle and a smaller round tubercle at the 

 base of the fourth toe. The tibio-tarsal articulation reaches 

 the tip of the snout or a little beyond. Skin smooth or 

 finely shagreened above ; a very narrow dorso-latcral glan- 

 dular fold. Pale grey or greyish brown above, uniform or 

 with small brown or black s[)Ots ; a more or less distinct dark 

 bar between the eyes ; sometimes a daik A between the 

 shoulders ; a dark brown or black canthal streak and a large 

 temporal spot of the same colour covering the tympanum ; 

 limbs with dark cross-bars; lower parts white, throat and 

 breast closely spotted or marbled with grey or brown. Male 

 unknown. 



Total length 57 mm. 



Five specimens from Kanshirei Village, altitude about 

 20U0 feet. 



But for the less oblique loreal region and the dilated toes, 

 this sjjecies resembles strikingly H. japonica, Blgr. It is 

 also allied to It. jnorteuseni, Blgr., which difi'ers in a stouter 

 habit, a much thicker and more prominent dorso-lateral fold, 

 and in the lighter colour of the tympanum. li. sauteri 

 lurnishes another interesting link between the " Ranie tem- 

 porariaj " and the " llyloranse."
