XXI. — Note on Orbitolites italica, Costa, sp. {Orbitolites 

 tenuissima, Carpenter). By Henuy B. Brady, F.H.S. 



In the paragraphs relating to the distribution of Orbitolites

 compare them with those in pi. xv. of the present Report, 

 especially with fig. 7, or with the central portion of one of 

 the figures given by Dr. Carpenter (" Report on Orbitolites,"

 ments, a circumstance sufficiently accounted for by the extreme 

 tenuity of the test." To which is appended the following
