W. * * * * * The specific distinction given by Linnaeus to _Strombus urceus_ is so loose, that his followers have referred all the small species of this genus to the numerous varieties he has quoted, though few will doubt that many permanent species have been thus overlooked; among these the one now characterized is an example, the most striking distinctions of which are in the spire being never plaited, and always much shorter than the mouth, which latter is either nearly white, or of a flesh colour; in its external colouring no two specimens will be found alike. It is not an uncommon shell from the East Indies, and seldom grows larger than the figure. * * * * * STROMBUS dilatatus, _Winged Strombus--middle figures._ * * * * * _S. testa transverse striata; spira mediocri, plicis numerosis gracilibus; labio exteriore dilatato, rotundato, crassissimo, reflexo; interiore supra crassescente, medio laevi; apertura striata._ Shell transversely striated; spire moderate, with slender numerous plaits; outer lip dilated, rounded, very thick, and reflected; inner lip thickened above, smooth in the middle; aperture striated. * * * * * An undescribed species, and of the greatest rarity, for I have never seen any other specimen, than one in my own cabinet, although perfect in form, it is obviously faded in colour; yet it is too remarkable to be mistaken for any other of this interesting family, which requires so much illustration. * * * * * Pl. 72 [Illustration] POGONIAS hirsutus, _Hairy-breasted Toothbill._ * * * * * GENERIC CHARACTER.--See Pl. 68. * * * * * SPECIFIC CHARACTER. _P. supra fuscus, maculis sulphureis, subtus sulphureus maculis nigris interstinctus, capite juguloque nigris; pectoris plumis elongatis, pilis setaceis terminatis._ Above brown, spotted with sulphur; beneath sulphureous, with black spots; head and chin black; feathers of the breast lengthened, and ending in long setaceous hairs.
