PETRIFIED FINGERS, CANDLES, SPECTRE CANDLES, &c. are vulgar terms by which fossils of the genus Belemnites were formerly known. PHAKELLOPLEURA. Guild. A genus composed of those species of CHITON, Auct. which have bunches of hairs or hyaline bristles on each side of each valve on the margin. The Chiton fascicularis, found on our own coasts, is a well known example. Fig. 506. PHARAMUS. Montf. LENTICULINA, Bl. A genus of microscopic Foraminifera. PHARETRIUM. König. ([Greek: pharetreôn], _pharetrion_, a quiver.)--_Descr._ A testaceous body composed of two conical sheaths, one within the other, perforated at the apex, and joined together near the oral margin. P. fragile, fig. 3. In describing this genus, which appears to be the same as ENTALIS of Defrance, Mr. König expresses the supposition that it may probably belong to the class Pteropoda. PHASIANELLA. Auct. (_Phasianus_, a pheasant.) _Fam._ Turbinacea, Lam. Ellipsostomata, Bl.--_Descr._ Smooth, oval, variegated; aperture entire, oval; outer-lip thin; inner-lip thin, spread over a portion of the body whorl; columella smooth, rather thickened towards the base; operculum horny, spiral within; testaceous, incrassated without. Britain, Mediterranean, &c.; the fine large species are Australian. Some fossil species are found in the tertiary beds.--_Obs._ The shells composing this genus are richly marked with lines and waves of various and delicate colours, and if the genus be restricted to those species which are smooth, and which have a thick shelly operculum, we may regard it as well defined; but there are some spirally-grooved species of TURBO, Linn. which, from their oval shape, have been considered as belonging to this genus. Such species should not, in our opinion, be retained in this genus; they belong to Littorina. P. variegata, fig. 367. PHITIA. Gray. CARYCHIUM, Müller. PHOLADARIA. Lam. A family of the order Conchifera Dimyaria, Lam. The animals contained in this family live in cavities bored by themselves in rocks, wood, &c. They are cylindrical in form. Lamarck here places PHOLAS and GASTROCHÆNA, the last of which belongs more properly to the family of Tubicolaria, where we have enumerated it. Pholas has been divided into _Pholas_, fig. 55, _Martesia_, which has the valves nearly closed; and Pholadidæa, fig. 56, which has the cup-shaped extension. The genus Pholadomya, fig. 67, has been added, although of doubtful character. The genus Galeomma, fig. 58, 59, has also been recently added. PHOLADIDÆA. Leach. PHOLAS papyracea, Auct. Remarkable for the cup-shaped process at the posterior extremity. Fig. 56.
