124 CIRRIPEDA. PKDUNCULATA. 



unequal, to the number of thirteen or more, the lower ones 

 on the sides smallest. 



P. cornucopia, Leach. (L. pollicipes, Gmel.) Peduncle imbricated 

 with scales, the scales pointing upwards and rounded at their ex- 

 tremities. European seas. B. Brown's Illust. pi. 5. fig. 11, 12. 



P. scalpellum, Lam. Peduncle scaly, attenuate below ; shell com- 

 pressed, with thirteen smooth valves. Inhabits Northern seas.

Gen. 4. AN AT IF A, Brug. Lepas, Lin. 



Body covered with a shell, and supported by a tubular and ten- 

 dinous peduncle ; tentacular arms numerous, long, unequal, 

 articulated, ciliated, arising near the summit on one side. 

 Shell compressed on the sides, with five valves, the valves con- 

 tiguous, unequal, the lower lateral ones largest. 



The branchiae of the Anatifae, according to Cuvier, are the appendages in the form 

 of elongated pyramids adhering to the exterior base of the cirri. 



A. Icevis, Lam. (Lepas anatifera, Lin.) Shell compressed, smooth, 

 somewhat triangular, with a long transversely rugous peduncle. 

 Inhabits all seas, attaching itself to the bottoms of ships and sub- 

 merged wood. B. Brown's Illust. pi. 4, fig. 1, 2, 3, 4. 

 The peduncle in this species is sometimes nearly nine inches long. It is further 

 remarkable as having given rise to the opinion, once seriously entertained, that it 

 was the young of a species of goose. The exserted cirri certainly bear some resem- 

 blance to feathers, but in no other respect does this equivocal generation seem coun- 

 tenanced by the habits or appearance of the animal. Gerard the botanist, however, 

 thus writes from his own personal observation : " What our eyes have seen and hands 

 have touched we shall declare." On the trunks and branches of old trees cast up 

 by the sea, " is found a certaine spume or froth, that in time breedeth unto certaine 

 shells, in shape like those of the muskle, but sharper pointed, and of a whitish 

 colour, wherein is contained a thing in form like a lace of silke finely woven as 

 it were together, of a whitish colour ; one end whereof is fastened unto the inside of 

 the shell, even as the fish of oisters and muskles are ; the other end is made fast 

 unto the belly of a rude masse or lumpe, which in time commeth to the shape and 

 form of a bird : when it is perfectly formed the shell gapeth open, and the first thing 

 that appeareth is the foresaid lace or string ; next come the legs of the bird hanging 

 out, and as it groweth greater it openeth the shell by degrees, till at length it is all 

 come forth, and hangeth only by the bill ; in short space after it commeth to full 

 maturitie, and falleth into the sea, where it gathereth feathers, and groweth to a 

 foule bigger than a mallard, and lesser than a goose, having blacke legs and bill or 

 beake, and feathers black and white." " For the truth whereof, if any doubt, may 

 it please them to repaire unto me, and I shall satisfie them by the testimouie of good 

 witnesses." Gerard's Herbal, p. 1587, 1588. 



A. dentata, Lam. Shell compressed, smooth, with five valves, and 

 the dorsal ridge serrated. Inhabits the Mediterranean sea. B. 

 Browns Illust. pi. 4, fig. 5. 



A. striata, Lam. Shell small, triangular, subcompressed, with the 

 valves sharply striated. Inhabits coasts of Great Britain, on ma- 

 rine plants, Crustacea, and testaceous mollusca. B. Browns Illust. 

 pi. 5, fig. 1, 4, 5, 6.
