A dull sermon, for instance, makes half the congregation "fissirostres."
In the conirostres are the perfections which belong to the incessores as an order, with the conspicuous external feature of a comparatively small notch in their bills; in the dentirostres, the notch is strong and toothlike, (hence the name of the tribe) assimilating them to the raptores; the fissirostres come into analogy with the natatores in the slight development of their feet and their great powers of flight; the tenuirostres have the small mouths and long soft bills of the grallatores.
