ANATIFOPSIS. 



Oedee— CIRRIPEDIA, Burmeister, 1843 (?). 

 1. Genus — Anatipopsis, Barrande, 1872. 

 1. Anatifopsis ? ANGLiCA, n. sp. PL I, fig. 4. 



Vescrvption. — Form eloDgate, subcylindrical, flatly convex. Upper margin 

 bluntly elbowed at about one-fourth its length from the proximal end. Lower 

 margin straight, inclined at a small angle to the upper margin. Proximal end 

 concave, bounded by a narrow-margined rim. Distal end defective. 



Size. — Length 24 mm., breadth 7 mm. 



Locality. — There is a single specimen from Sloly in the Porter Collection. 



BemarJcs. — This fossil shows no definite structure, the markings generally being 

 too much like those on the adjoining matrix to be relied on. Its shape is peculiar, 

 and may be described as resembling the breech portion of a gun. It sufiiciently 

 resembles the fossil named Anatifopsis acuta by Barrande^ to be regarded as 

 possibly congeneric, differing from it in being much more elongate, and not 

 showing the arching distal end seen in the Bohemian species, which Barrande 

 considered as akin to Lepas. Two obscure spots, however, occur on the convex 

 surface of our specimen, one of which seems pectiniform. In Dr. Woodward's 

 opinion this pectination may indicate the remains of gastric teeth, and therefore 

 imply that it is a Phyllocarid. 



Affinities. — A. longa, Barrande,^ which approaches it in length, has a straight 

 upper margin.
