The strongly contrasted light and dark shades of color are not unfre- 

 quently preserved in the insects of this formation. I suspect that had the 

 rectrices of this species originally displayed the alternating white and dark 

 cross-bars characteristic of the Totani, some trace of them would be dis- 

 coverable in the fossil, in spite of the fact that the entire feather is repre- 

 sented by carbon only. The brown tint of the specimen, both light and 

 dark, is uninterrupted by pattern of any kind. 



The tail is rather longer tlian in the Trmrjce, about equal to that of 

 many plovers and Totani, and shorter than that of Actiturus. 



The CJiaradrhis sheppardianus was discovered near Florissant, Colorado, 

 by Dr. Gr. Hambach, a skillful naturalist. I have named it in honor of Ed- 

 win Sheppard, of Philadelphia, an excellent ornithologist and skillful artist.
