IV. ORBITOLIN A = P ATELLIN A. 
(See pages 10, 17, and 19.) 
The name Orbitolina has been applied to two different organisms. One of 
these has been of late years referred to Williamson’s genus Patellina, which, 
though very small and delicate in British seas, formerly existed (in Cretaceous 
times) of much larger and relatively gigantic size. This is the Patellina lenti- 
cularis ( Madreporites , Blumenbach) of the Perte-du-Rhone and elsewhere. 
The other organism (globular, conical, or concavo-convex in form) is the 
u Orbulites pileolus ” of Lamarck, and the u Millepora ? globularis ” of Phillips ; 
and it has also passed under other names. Of late years Steinmann and Carter 
have determined that this little fossil is Hydractinian in its relationship; and 
the former has referred it to the new genus Porosphcera. Some of the smallest 
specimens so much resemble Tinoporus vesicular is, that Parker and Jones referred 
both the globular and conical forms of this fossil to the genus. 
The following remarks on Patellina lenticularis may be useful : — This is 
the Madreporites lenticularis of Blumenbach, 1805, according to Bronn ; also 
the Orbulites lenticnlata of Lamarck (1816) and of Lamouroux. Referred to 
Orbitolina as a Foraminifer by d’Orbigny in 1847, it was put into relationship 
with several allies by Parker and Jones in the Ann. & Mag. Nat. Hist. 1860, 
ser. 3, vol. vi. p. 29 &c. ; and these were subsequently revised by Carpenter, 
Parker, and Jones in the ‘ Introduction to the Study of the Foraminifera,’ 
1862, p. 223 &c., and in the Ann. & Mag. Nat. Hist. September 1863, p. 212. 
H. J. Carter in 1861, Ann. & Mag. Nat. Hist. ser. 3, vol. viii. p. 457 &c., had 
already reviewed and added to the history of the species as known at that date. 
So that we now know : — 
Patellina simplex, P. & J. Tertiary, Grignon, near Paris. 
semiannularis , P. & J. Tertiary, Grignon ; and Recent, Australia. 
corrugata, Williamson. Recent: British, Arctic, Mediterranean Seas. 
annularis, P. & J. Recent : Melbourne. 
cretacea * ( Cyclolina, d’Orb.). A flat form. Cenomanian (Lower Cre- 
taceous) : He Madame, Dept. Charente-Inferieure, France. 
lenticularis (Blumenbach). Cenomanian : Perte-du-Rhone, Dept. Ain ; 
St.-Paul-de-Fenouillet, Dept. Aude. Aptian : Dept. ITsere {Gras'). Upper 
Greensand (Lower Cretaceous) : Haldon Hill and Milber Down, in Devon- 
shire. Cretaceous (P) : S.E. coast of Arabia {Carter).
