 brown hair-tips. The dark stripes meet anteriorly. From collar a 

 dull orange-ochraceous stripe about 5 mm. in width extends back 

 over middle of chest to join the pale orange-buff area 80 mm. long 

 by 40 mm. wide which occupies middle of belly. With these ex- 

 ceptions the entire under surface of body is white. Tail white 

 below and at tip, like back above but not as bright, and much less 

 grizzled.
