sent case true relationship, as far as it can be traced, bears 

 out the conclusion that had been arrived at on different 

 grounds — namely, that Fusulina finds its most appropriate 

 place in the family Nummulinida, though amongst the least 

 highly organized members of the group. 



In conclusion, these notes are brought forward as a slight 

 contribution to the history of a single section of a large and 

 important genus of Foraminifera ; and no attempt has been 

 made to invest them with a more general character. The 

 material in the hands of Dr. Stache and Dr. Schwager will 

 furnish a basis for much wider treatment of the subject ; and 

 care has been taken to avoid touching on the points that have 

 specially occupied their attention, lest their results should in 

 any way be forestalled. 



EXPLANATION OF PLATE XVIII. 



Note. — In fig-ures 1, 13, 15, and 16 two views are given of the respec- 

 tive specimens. In each case, a represents the aspect in the line of view 

 perpendicular to the axis, b the aspect from a point on the line of the 

 central axis. 



Figs. 1-4. Fusulina cj/lhidrica, Fischer, typical form. Figs. 3 & 4 are 

 worn and broken specimens. All magnified 10 diameters. 



Fiffs. 5 & G. Fusulina princeps (Ehrenberg). x 12 diam. 



Fiffs. 7-9. Fusulina sphferoidea (l^hrenherg). X 12 diam. 



Figs. 10-13. Fustdina cequalis (D'Eichwald). X 12 diam. This form is 

 often found split on the median plane 5 fig. 12 represents such a 

 specimen. 



Figs. 15 & 16. Represent worn specimens, scarcely more than casts, of 

 varieties like those embraced in F. sphcsroidea. X 12 diam. 



F^gs, 17 & 18. Somewhat unsymmetrical examples — the two sides, as 

 measured from the median plane, being unequal in size and con- 

 vexity. Such specimens lead up to the "Nummulina " antiquior 

 of RouiUier and Vosinsky, which is doubtless a Fusulina of this 

 sort, though of larger dimensions and with the asymmetry more 

 fully developed, x 12 diam. 



Figs. 14, 19-21. Various worn, irregular, or otherwise unsymmetrical spe- 

 cimens. X 12 diam.
