extremity as far distally as the boundary line indicated in the 

 figures the skin is hairy. The same characteristic prevails in 

 all the prosimians, and reference to it need not be repeated 

 hereafter. Observations could be made only on the areas 

 listed below, as shown in the figures.

Supplementary note 



Since the completion of this work we have had opportunity 

 to examine one hand and one foot of an adult specimen in an 

 excellent state of preservation, loaned by Dr. A. H. Schultz 

 (D. madagascariensis, Schultz 's number 393). In the hand the 

 only points of difference from the two hands here illustrated 

 are: occurrence of islands instead of continuous ridges over 

 the thenar region (compare variations in ridge extent in figs. 

 5 and 6) ; presence of a whorl in interdigital III (instead of 

 open field or loop, as found in the other three hands). The 

 plantar dermatoglyphics of this specimen do not differ in any 

 essential from the features as drawn in figures 7 and 8. It 

 should be noted, however, that central pads of the sole are 

 indicated as prolongations from the related interdigital pads, 

 separated from them by the distal transverse flexion furrow.
