 cate, with projecting rihlets. The curvature of the top forms a 

 small head, somewhat in the form of a knot." 



As we have above stated, this is the very slender Spiroline 

 form of Peneruplis described by Gmelin as Nautilus Lituus (see 

 Ann. Nat, Hist. ser. 3. vol. iii. p. 481).

Note to a Paper on Plesiosaurus macropterus. 



To the Editors of the Annals of Natural History. 



Gentlemen, — The proof of the paper on a "New Lias Plesiosaur" 

 (in the ' Annals ' for January) reached me under circumstances which 

 precluded revision. Hence there are many omissions, three of which 

 I wish to supply at once. 



1 . Plesiosaurus homalosj)ondylns, to the best of my knowledge, 



Itin. Orient.' (17/5, p. 125), as follows: — "Having compressed whorls,, 

 transversely sulcated, and marked with slight longitudinal striae; the aper- 

 ture perforated with pores. Colour snow-white. Whorls straight at the 

 base [top], often dilated, sometimes linear ; apex [earliest part] convolutely 

 spiral."
