A singular coincidence of application, if it has no nearer connection, by the Polynesian and the Latin of this word to similar purposes, occurs in the huhui and hui-tarawa of the former and jugulæ of the latter. In Hawaiian huhui designates a constellation generally, but especially that of the Pleiades; in Tahitian hui-tarawa, lit. the transverse or horizontal cluster, designates the stars generally called Orion's belt, and in Latin jugulæ represents the very same stars in the constellation Orion.
