XIPHI AS, {Cycl.) in the Linnaan fyftem of zoology, the name of a genus of fillies of the general order of the acanthopterygii or prickly-finned kind.
The characters of this genus are, that the membrane of the gills has eight bones, and the point or extremity of the nofe or fnout of the fifh, is fhaped like a fword, and that it has no belly fins. Linntsi Syft. Nat. p. 54.
According to the Artedian fyftem of ichthyology, the charac- ters^ this genus of fillies are thefe : The branchioftege mem- brane on each fide contains about eight bones, the fnout is extended into a very long and depreffed point, imitating the figure of a fword, and of a bony fubftance ; the body is ob- long and roundifh, the back fin is fmall, and is very low in the middle ; there are no belly fins at all. The air bladder in this fifh is remarkably long, and the anus Very near the tail. Artedi Gen. Pifc. p. 24.
The SwordfiJIi is fo remarkable for the fliape of its fnout, which is extended in form of a fword, that it has been called by all nations by a name expreffive of that character. Its common name Xipbias is from the Greek &<plu a fword, and it is called gladius in Latin, and in Englifh the Swordfijb, It grows to a very confiderable fize, fo as fometirnes to weigh an hundred pounds. It is of a long and rounded body, largeft near the head, and tapering by degrees toward the tail ; its fkin is confiderably rough, its back black, and its belly of a filvery white ; its mouth is of a moderate fize, and has no teeth ; its fnout runs out into the figure of a fword in the up- per jaw, the under is much fhortcr, and terminates in a very lharp point ;. it has one only fin on the back, running almoft the whole length of it ; its tail is very remarkably forked ; it has only one pair of fins at the gills, having none on the belly. It is common in the Mediterranean, and fome other feas, and is efteemed by many a very delicate fifh for the table; The Manner of fifhing for it is the fame at this time, that the old writers have defcribed it to be in theirs, by the harpiiur-iron. milugbb/s Hift.

We have feveral fpecies of this beautiful plant cultivated in our gardens, where they are called bulbous Iris's ; and befides thefe, a vaft number of varieties or new flowers, as the florilh call them, are frequently raifed by thofe who propagate them from feeds. The culture of thefe being the fame with that of feveral other plants of the fame fort, which are much va- lued for their flowers, it may not be amifs to give it at large. There mould be great care to fave the feeds of the fineft and ftrongeft flowers, and in September fome fhallow pans or boxes muft be placed with holes at their bottom to let out the moifture, and then filled with light and fine earth. On this the feeds muft be fown pretty thick, and as evenly as may be ; half an inch of the fame earth mult be fifted on thefe, and the boxes mud then be ftt where they may have the morning fun ; and if the weather proves very dry, they muft be gently watered at times. They muft remain in this fituation till October, and then muft be removed to a place where they may have the benefit of the fun as great a part of the day as may be ; here they muft ftand the winter, keeping the boxes very carefully clear from weeds. In the fpring the young plants will appear, and they ihould then be removed to their firft fituation, where they may have only the morning fun; and if the weather be dry* they muft be watered at times. In June their leaves will de- cay, and they muft then have half an inch of frefh earth fifted over them, and be left in their fituation till October, when they muft be removed to the fame place as before for the winter.
In the fpring the leaves will appear again, and when they are again perifhed, the earth muft be taken out of the boxes, and fifted to feparate the roots, which muft then be planted at three inches diftance on a bed of the fame light earth ; they muft be buried three inches deep, and in the fpring following muft have about half an inch of frefh earth fifted over them ; the leaves will this year appear and decay as before ; and the following year, in June, they will moft of them flower, when the fineft flowers fhould be marked, that their roots may be taken particular care of. The following year the remainder, which did not flower at firft, will produce their flowers ; fuch of thefe as are finer than the reft, fhould be marked in the fame manner, and the roots of thefe choice kinds be preferved with particular care. Whatever fine or new flower is thus raifed from feed, may be afterwards propagated by off-fets from the roots, which being planted out, will flower the fe- cond year, and often produce even finer flowers than the mo- ther root.
The roots of thefe flowers fhould be taken out of the earth only every other year ) this fhould be done juft when the leaves are decayed, and they fhould not be kept out of ths earth above a fortnight.
The earth in which thefe flowers thrive beft, is a light fandy loam ; and if it be taken up with the turf and the grafs rotted among it before it is ufed, it will be fo much the better. They do not delight in a rich dunged foil, nor fhould they be placed where they are too much cxpofed to the fun ; for be- fides that the flowers foon fade in thefe places, the roots are alfo always found to decay ; but in an caft border, where they may have the fun till eleven o'clock, and where the ground is not too moift nor over dry, they will ftand a long time in flower, and thrive extremely well.
