422 Mr. C. O. Waterhouse on two 



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

 out tlie conclusion that had been arrived at on different 

 grounds — namely, that Fiisulina finds its most appropriate 

 place in the family Nunmiulinida, 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. Sch wager will 

 furnish a basis for much wider treatiiient 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.

Note. — In figures 1, 13, 15, and 16 two views are given of the re8j)ec- 

 tive sppcimeus. In eacli case, a represents tlie 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 cyUndrica, Fischer, typical form. Figs. 3 & 4 are 

 worn and broken specimens. All magnified 10 diameters. 



Figs. 5 & G. FiisttUna pn'nceps TEhrenberg). X 12 diam. 



Figs. 7 -Q. Fusulina sphceroidea (Ehrenberg). X 12 diam. 



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

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

 specimen. 



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

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



Figs. 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 "Nmnnnilina " antiquior 

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

 sort, though of larger dimensions and with the asymmetry more 

 fuUy developed. X 12 diam. 



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

 cimens. X 12 diam.
