Hi 



There is .some variation in specimens in the relative distance of one 

 nostril from the other and from the eye. In some specimens these dis- 

 tances are identic^il ; in others the former is somewliat less than the 

 latter, and the same measurement, usually one half the w idth between 

 the eyes, may enter it L'.'_'."i times. 



A local variety is .seen in three .specimens (No, 7()(>r») from Abbeville. 

 S. C. These aie a li.yht brown, much resembling the G. /'iisviis, but are 

 spotted with a darker brown. The double papilhe are not vi.sililc on 

 the superior surface of the head, and are faintly marked on the inferior 

 aspect. The rows of pores are, however, as in C. (iIletilicniciiKis, as are 

 the tongue and internal nares. The digits are all iikhc .slender, and the 

 dirmal ala 011 the extei iial toe and that of the elbow are niiieli reduced. 



IJesides the generic character, the following dirfereiices may be ob- 

 served on comitarison of this .siiecies with the Mcnidiihiitfaclnis ina.rimus- 

 of Asia. In the latti r the tongue is not free, luit is sessile, and with- 

 out plica'; head with rows ofoltu.se tubercles; sidcy and limbs williont 

 dermal folds.
