Of these four heads I take the specimen marked No. 1 in the figures to be the oldest, if not, as I have already said, a full-grown bird, while the others become younger and younger, as indicated by their num- bers. No. 4 being the youngest of all. The figures of these beaks were all drawn from the specimens by Mr. John L. Ridgway, a brother of the ornithologist. They are carefully and accuratelv done, as is all the work of this artist. In figure 1 I have added the letters from a to g in order that we might have something to designate the parts by in referring. Figure 2.
