P,Y MALCOLM A. SMITH. 31 



I have recently examined a large series of jB. horbonica from 

 near Kuan Nieng, S.W. of Patalimg, in Peninsular Siam. 



68. Nectophryne guentheri Bouleng. 



Mt. Poi, 4500--5000 feet. 



69. Nectophryne everetti Bouleng. 



Mt. Dulit, 4000 feet. 



One imm. ex. ; from snout to vent 19 mm. 



The tympanum is entirely hidden. Colour in alcohol, light 

 brown above with very dark brown markings ; warts on the 

 flanks whitish. 



70. Nectophryne stgnata Bouleng. 



11 exs. from Mt. Penrissen at 2000 feet. 



The largest measures 38 mm. from snout to vent; all the 

 others are under 28 mm. 



I have referred these specimens to N. signata which may have 

 been described from a very young example. As shown by the 

 speciraens mentioned above, the characters which define this 

 species are not very constant. The tympanum is variable in 

 size and may be from two-thirds to less than one-half the 

 diameter of the eye ; it is always very distinct . The web of 

 the toes is fuller in the juveniles than in the large specimen, 

 but three phalanges of the fourth toe are always free, although 

 the membrane extends as a fringe along either side to the disc. 

 The heel reaches the tip of the snout in some and to well 

 beyond in others. The discs of the fingers are strongly dilated 

 and truncate at the end in the largest example, not so strongly 

 dilated in the juveniles. 



The colour above is light or dark brown with most of the 

 larger warts tipped with pink. Limbs yellowish or brownish 

 barred with darker brown. Below yellowish, spotted and 

 speckled with black. 



BKEVICEPITINAE. 



71. Kalophrynus pleuro stigma Tschudi. 



Kuching. 



72. Sphenophkyne leu co stigma Bouleng. 



Kuching. I have elsewhere referred to the status of 

 this species {antca p. 13).
