XVI. Nautilus {L.) acicularis. The Needle-shaped Bishop-staff. 

 PL 6. figs. 16 a, \Qb. [Spirolina LituuSj Gmelin.] 



(Trans.) " This is a linear or awl-shaped shell, extraordinarily deli- 

 cate, with projecting riblets. 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 Peneroplis described by Gmelin as Nautilus Lituus (see 

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



The following is a summary of the forms figured by Batsch : —

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 homalosjwndylus, to the best of my knowledge, 



Itin. Orient.' (1775, 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."
