golden ; referring to the under parts of this variety, which are yellower than those of 

 palmarum. Properly, hypo- in such connection simply diminishes the force of the adjec- 

 tive ; hjpoleucus, hi/pochrijseus,. mea,mng whiti'sA, yellowi'sA; but the present is an estab-

dance of the species in the fall, in comparison with its scarcity in the spring. — Lat. agilis, 

 agile, from ago, I act ; literally, do-able, that is, act-ive ; the adjectival termination being 

 simply applied to the root of the verb, both in Latin and Englisli. 



140. O. for-mo'-sa. Lat. /ormosa, beautiful ; primitively, in the sense of shapely, well-formed, 



in good or full proportion; forma, form. So said of Juno, in whose "lofty mind" 

 remained judicium Paridis, spretaque injuria forma, h.e.,ol her slighted beauty. Verg., 

 Mn., i, 27.
