 lores, sides of head below and l)ack of e_yes, down to a little below line of 

 gai>e, plumbeous with a brownish wash on lores; chin and throat pure

 bistre brown streaked with grayish and shading through grayish Vjrown 

 into dingy cinnamon washed with dull gray along median line; breast 

 light cinnamon rufous ; sides of body and Hanks varying from olive brown 

 to dark hair brown strongly marked with transverse white bars; under tail 

 coverts white with narrow shaft streaks of dusky brown. 



Measuremevts. — Wing, 142 ; tail, CO ; culmen, 53 ; tarsus, 51. 



Remarks. — This rail is most like JidUu.i crepifdnK ?/v(//;u'/, especially on the 

 underparts, but the breast and under side of the neck are redder and the 

 dusky bars on the flanks are slightly darker. The upperparts differ more, 

 as the top of the head and neck are lighter brown and the? gray and brown 

 streaks on the back are much more strongly contrasted. It is much paler 

 and more brightly colored than 7ia//H.s ^. cwn'i.TUS ; the \mve white throat, 

 cinnamon rufous breast and strongly contrasted gray and brown strijjes on 

 the back being very distinctive. 



From the pale colors of this bird it is probable that it will be found 

 limited to the arid coast region of the peninsula of Yucatan though it may 

 range still farther north along the shore of the Gulf of Mexico. The type 

 is the only specimen I liave seen.
