 tibia naked ; colour uniform blackish or seal-))rown above and 

 beneath. Forearm 139-143"5 mm. Hab. Guadalcanar. 



Teeth (fig. 22, A', B', C'). — p' quite or very nearly as broad as 

 long (actual measurements from four individuals, antero-posterior 

 diameter of crown 4'8-52 mm., transverse diameter 4-7-4'8); 

 anterior basal ledge broad, extending as a well-marked shelf on 

 inner side of tooth round base of inner main cusp, which is conse- 

 (jucntly cut off from inner side of tooth and practically situated ou 

 the crushing surface ; posterior ledge heavy, particularly postero- 

 internally, and generally extending forward along inner base of 

 tooth, thus nearly reaching inner prolongatiou of anterior ledgo 

 (fig. 22, A') ; inner main cusp shortened anlero-posteriorly, i. e. it 

 has entirely lost its character of a longitudinal ridge and is trans- 

 formed into a conical cusp. ]>' and m' differing from corresponding 

 teeth of Ft. ancc'ps in essentially the same characters as p'. — |'^, m,, 

 and m, more shortened than in Ft. ancej^s, about one-fourth longer 

 than broad. Is'otch in cutting-edge of outer main cusp of p^and m^ 

 considerably deeper (compare fig. 22 C with C) ; inner main cusp 

 of same teeth cusp-like (conical), less ridge-like, than in anceiJS. —
