III. — The CrEKiPEDE ^Brachylepas ceetacea\ H. Woodward. 



By Thomas H. Withees, F.G.S. 



(PLATE XX.) 



[Concluded from the July Number, p. 326.) 



LN addition to the valves from Liineburg herein mentioned, it has 

 been possible to examine the more important ot the material 

 described by previous authors, namely: (1) the valve figured by 

 H. Woodward (1868) as Pyrgoma cretacea, and subsequently (1901) as 

 Brachylepas cretacea, now in the British Museum (Natural History), 

 registered I. 14029 ; (2) the nearly complete capitulum figured as 

 B. cretacea by H. Woodward (1901), in the collection of Dr. A. W. 

 K,owe, of Margate; (3) the valve figured by Marsson (1880) as 

 PoUicipes cancellatus, together with other valves studied by him, now 

 in the Geologisches Landesmuseum of Berlin ; (4) the valve figui'ed 

 by Quenstedt (1883) as P. lavissitnus,^ now in the University of 

 Tiibingen; (5)the valve mentionedbyBoehm(1906),in the Geologisches 

 Landesmuseum of Berlin; and (6) a large number of more or less 



' I have been unable to ascertain the whereabouts of the series of valves 

 figured as Pollicipes Icevissimios by Zittel. Dr. E. Dacque kindly informs me 

 that they are not in the collection of the Palasontological Museum, Munich.
