LITUITE. BACULITE. 
365 
years ago was imported largely to various parts 
ef Europe for architectural purposes.* 
Lituite. 
Together with the Orthoceratite, in the Tran- 
sition Limestone of Oeland, there occurs a cognate 
§enus of Chambered shells, called Litiiites. (PI. 
44, Fig. 3 .) These are partially coiled up into 
^ Spiral form at their smaller extremity, whilst 
their larger end is continued into a straight tube, 
considerable length, separated by transverse 
plates, concave outwards, and pei’forated by a 
^iphuncle (a). As these Lituites closely resemble 
the shell of the recent Spirula (PI. 44, Fig. 2), 
their office may have been the same, in the 
economy of some extinct Cephalopod. 
Baculite. 
As in rocks of the Transition series, the form 
nf a straight Nautilus is presented by the genus 
* Part of the pavement in Hampton Court Palace, that of 
hall of University College, Oxford, and several tombs of the 
>ngs of Poland in the cathedral at Cracow, are formed of this 
garble, in which many shells of Orthoceratites are discoverable. 
® largest known species are found in the Carboniferous lime- 
of Closeburn, near Edinburgh, being nearly of the size of 
•'aan s thigh. The presence of such gigantic Mollusks seems 
indicate a highly exalted temperature, in the then existing 
nuate of these northern regions of Europe. See Sowerbv’s 
Con. PI. 246.
