ser Gattung hauptsächlich durch vollständigen Mangel der 

 Schvvimmhaut an den Vorderfiissen und die sehr langen Hin- 

 terbeine gut getrennt, wie auch die Zeichnung unH fein chag- 

 rinierte Oberseite nicht'; mit bekänn ten Arten iibereinstimmt.» 

 To this preliminary description of this new species I only 

 want to add, together with the fignre, some measurements 

 for a comparison between this one and Chiromaniis rttfescens, 

 of which species there are to be found four specimens in the 

 colJection. 



As shown by the table, there exists a remarkable diffe- 

 rence in the length of the extremities; especially the tibia 

 and the foot with the 4th toe are in Ch. lepus exceedingly 

 prolonged; but also the front limbs and the fingers are of a 

 considerable length in comparison with those of Ch. riifescens. 

 The distance between the tip of the nose and the hind mar- 

 gin of the tympanum is, as shown above, much greater in 

 Ch. lepus, being due as well to the much larger tympanum 

 of this form, the diameter of which comes up to 4 mm. 

 whilst in Ch. rujescens it only measures 2,4, 2,8 and 3 mm., 

 as also to its place further back from the eye. 



3 specimens measured.
