741. Er-is-ma-tu'-ra rfib'-I-da. Gr, fpeicr/j.a, a stay, prop, pier, and ovpa, tail, as the stiffened 



member of the bird might seem to be. Lat. rubidus, ruddy, reddish. 



742. N5m-5'-nyx dfim-In'-I-ca. Gr. va^os, law, order, regular way, and uw, nail. The nail at 



the end of the bill in all the species of so-called Erismatura, except rubida, is formed in a 

 particular way. See Dendrceca, No. 129. . 



743. Mer'-gGs mer-gan/-s6r. Lat. mergus, a diver; mergo, I dive, mergere, mersi, mersum> 



whence submerged, immersed, &c. Merganser is simply mergus + anser, i. e., diving- 

 goose. 



744. M. ser-ra'-tor. Lat. serrator, a sawyer; serratus, sawn, i.e., saw-shaped, serrate, serried, 



as the prominent teeth of the bill look like those of a saw ; serra, a saw ; supposed to be 

 equal to secra, from seco, I cut. 



745. M. cii-cul-la'-tus. Lat. cucullatus, hooded, wearing the cucuttum, a kind of hood, a capu- 



chon, perhaps from its circular shape (KVK\OS). Very appropriate in this case. 



746. SiiMa bas-sa'-na. Sula, by Agassiz given as a proper name, was Latinized lately from 



the French name, Le Side. Quasi-Lat. bassanus is an adjective derived from the name 

 of one of the great haunts of the bird, the Bass Rock, Firth of Forth, Scotland. 



747. S. Ieu-c6-gas'-tia. Gr. Aev/ofc, white, and ycurr-fip, the belly. 



This stands as S. fiber in the orig. ed. See Salv., Tr. Z. S. ix, pt. ix, 1875, p. 496. 



748. Pgl-e-ca'-nus trach-y-rhynch'-us. Gr. ireXeKav, or ireXficivos, or Lat. pelecanus, a pelican. 



The etymology is obscure; but the pelican was fabled to strike and wound its own 

 breast, that the young might be nourished with blood ; and there are various Greek and 

 Latin wofds signifying some cutting and striking instrument, as an axe, which are 

 nearly identical in form with the above. Gr. rpax^s, rough, uneven, and frvyxos, the 

 beak ; with reference to the deciduous excrescence or " centre-board " on the upper 

 mandible.
