724. F. val-lis-ner'-I-a. Vallisneria is a genus of aquatic plants, the wild celery, V. spiralis L., 



named for Antoine Vallisner, a French botanist. The name was applied to tlie bird 

 from its fondness for this plant as food. The name canvas-back, from tlie peculiar 

 coloration of the upper parts, is an Americanism which has been in use at least since 

 1800. (e.c/., see Barton, Med. and Phys. Journ., pt. i, vol. ii, 1805, p. 161.) 



725. Clan'-gii-la glaQ'-ci-um. Lat. clunfjula, diminutive of clanfjor, a clang, noise; the corre- 



sponding Gr. K\ayyfi means particularly the outcry of wild animals ; K\a.(to, future 

 KKay^o), I cry out. It was applied to this bird several centuries ago. — Gr. yXavKwv or 

 yKavKiov, a kind of wild duck, perhaps this very species. Under the varying forms of 

 ylaucion, glaucium, glaucius, and glaucia, it has been definitely applied to this duck for 

 more than three centuries. 



726. C. is-land'-i-ca. To Iceland. See Falco, No. 500. 



727. C. al-b6'-6-la. Diminutive (irregular) form of alius, white: albula would be better form. 



"Buffle-head" is a corruption of buffalo-head, from the puifiness of the head: "butter- 

 ball" from the fatness of the bird at times : " spirit duck," from the quickness of diving. 



728. Har-el'-da gla-ci-a'-lis. //areWa is a nonsense-word, invented by Leach. — Lat. glacialis, 



glacial, icy, relating to ice; glacies, ice. (Unde derivatur 1 cf. Gr. y\avKos) 



729. Camp-t6-laem'-ias lab-ra-do'-ri-us. Gr. Kafx-n-TSs, flexible, as leather is, for instance ; 



KOLfjL-Koi, I bend; and Aai^o's, the throat; but the whole word refers to the soft leathery 

 expansion of the bill, as if Camptorhjjnchns, for which latter word, preoccupied in zoology, 

 it was proposed as a substitute. — To Labrador ; which name is said to have been given 

 to the country by the Spaniards, it being considered cultivable, as Greenland was not; 

 Span, labrado, cultivated land ; lahrador, laborer ; labrar, to work. 



730. His-tri-6'-nI-cus ml-nu'-tus. Lat. histrionicus, histrionic, relating to histrio, a stage- 



player ; because the bird is tricked out in various colors, as if it were dressed to play 

 some part on the stage. The word is related in the most interesting manner to historia, 

 history, and histvlogi/, the science of tissues of the body ; the idea being the weaving 

 together of things, to make, as history, a connected account, as in histology, a tissue of 

 organs. We still say, for example, a tissue of falsehood, &c. These words are all 

 related to IcttSs, a loom, or the web woven on it.
