length. The character is not borne out by the Kuatun males, 

 two of which, measuring 110 and 83 millim. from snout to vent 

 respectively, I have examined in this respect : the testes have a 

 length of 12 and 11 millim., and a width of 4 and 3, the kidneys 

 measm-ing 21 and 19 millim. The organ in question is therefore 

 but slightly longer than usual in European specimens. 



10. Leptobeachiuh boettgeei, sp. n. (Plate XIX. fig. 3.) 



Tongue entire. Vomerine teeth none. Head moderate, 

 broader than long ; snout very short, obliquely truncate, 

 projecting beyond the mouth ; canthus rostralis angular ; loreal 

 region concave ; interorbital space as broad as the upper eyelid ; 

 tympanum very distinct, two thirds the diameter of the eye. 

 Fingers slender, slightly swollen at the end, first and second 

 equal. Toes slender, slightly swollen at the end, with a slight 

 rudiment of web ; a small, oval, flat inner metatarsal tubercle ; no 

 subarticular tubercles. The tibio-tarsal articulation reaches the 

 eye. Skin smooth, with small scattered warts on the head and 

 back ; two small white warts close together on the chin and one 

 on each side of the breast near the insertion of the fore limb. 

 Dark grey or brown above, with symmetrical blackish markings ; 

 upper surface of snout and scapular regions light ; a whitish 

 blotch on the upper lip below the anterior half of the eye ; limbs 

 with dark cross bands ; a small round white spot on the back oE 

 the thigh ; throat and breast brown or brownish ; three longi- 

 tudinal, blackish, light-edged markings on the throat ; large 

 blackish spots on the sides of the belly ; posterior part of bally 

 and lower surface of thighs dirty white. Male with internal vocal 

 sacs. 



From snout to vent, 6 35 millim., 5 46. 



Six specimens. 



Closely allied to L. monticola Grthi'. ; differing in the entire 

 tongue and the absence of vomerine teeth. Had I examined 

 but a single specimen, I should not have ventured to separate it 

 from L. monticola. That is my excuse, but I must, however, 

 apologize to Prof. Boettger for having, a few years ago, identified 

 a specimen from Kiukiang, which he submitted to me, as a young 

 individual of that species (c/. Ber. Senckenb. Ges. 1894, p. 141). I 

 wish to atone for mymistake by connecting with this new species the 

 name of my distinguished colleague. Lvalus lateralis And., which 

 I have placedin the synonymy of Leptohracliium monticola, regarding 

 it as based on a young specimen, agrees with L. sinensis in the 

 absence of vomerine teeth, but the tongue is described as sUghtly 

 notched behind. That the presence or absence of vomerine teeth 

 is a dangerous character to use, unaccompanied by others, in the 

 distinction of species in this genus has been shown in the case of 

 L. carinense Blgr. (c/. W. L. Sclater, P. Z. S. 1892, p. 347). The 

 length of the hind limbs varies much in L. monticola. In Giinther's 

 type specimen from Sikkim they bear the same proportions as in 

 L. sinense, the tibio-tarsal articulation reaching the eye.
