The long tail, however, comprises a row of twenty slender vertebrse, each bearing a pair of feathers. Owing to the fine grain of the stone, the feathers both of the wings and the tail are perfectly displayed in impressions, which were made when the actual feathers were originally buried in the soft limy mud. Of the second specimen of the Arc]iBeo])ie)ijx, now in theBerlin Museum, a plaster cast is placed next to the firstexample in Table-case 13. It retains the head, which isquite bird-sliaped, though its jaws are provided with teeth.
