168 SUPPLEMENT TO THE BRITISH 



in the Callovian formation, and in the Museum of the School of Mines in London there are 

 some examples of the var. Cattoviensis (Sup., PI. XXVI, figs. 28, 29), from the Kelloway 

 Rock of Kelloway. This form also occurs, according to Mr. E. Deslongchamps, in beds 

 characterised by Ammonites buttatus and Am. modiolaris, at the hillock of Escoville, at 

 Tannerville, and at other localities in the Kelloway Clay of Prance.

I have very little to add to the description I have already published of this species (?) 

 It differs from W. ornithocephala in having its lateral sides almost straight, and not 

 pinched in anteriorly, as is usually the case in the last-named species. It is also a larger 

 shell, more elongated, somewhat thicker, and with a more incurved beak and smaller 

 foramen. The smaller valve is more globose, straight, or slightly indented in front. 

 When presenting the last-named peculiarity it forms the variety I proposed to name 

 sublagenalis. 



In his notes " Sur le Terrain callovien " (' Bull. Soc. Linn, de Normandie/ vol. iv, 

 1859) Mr. E. Deslongchamps proposes to retain W. lagenalis and W. sublagenalis as distinct 

 species, but I feel certain that the specimens upon which I proposed to found the variety 

 are only indented examples of Schlotheim's species. Some abnormal forms of W. 

 lagenalis have been referred to W. ornithocephala. 



W. lagenalis, as we have elsewhere remarked, abounds in the Cornbrash of Boulogne- 

 sur-Mer, where some examples have attained fully two inches in length by one in width. 

 In England both W. lagenalis and the so-termed sublagenalis occur together in the Corn- 

 brash of several localities, and in a perfect state of preservation. Messrs. Walker and 

 Hudleston state that the species is common in the Cornbrash of Scarborough, and that it 

 occurs also in the Avicula-sh&les.
