OSCULIPORA, MULTIFASCIGERA. 
67 
close groups of apertures, which are biserial ; the apertures in each group very- 
crowded. Eeverse face smooth. 
Distkib. — Senonian — Maastrichtiau : Royau, Chareute-Iuferieure. 
Remarks. — The plate 800 bis on which this species was figured is not given 
in any of the copies of d’Orhigny’s Avork to which I have access, and there

SVXONYM. 
Meandrocavea ^ d’Orbiguy, 1854. 
Diagnosis. 
Osculiporidae with a massive zoarium which is either nodular 
or laminar ; it is composed of numerous superposed sheets, 
between which are open spaces. Each sheet has the characters 
of the zoarium of Lopholepis. 
Type Species. 
M. campicheana, d’Orbigny, 1853. iS’eocomian : Switzerland. 
Affinities. 
This genus was founded on a jS’eocomian species, which may be 
regarded as a compound Lopholepis, composed of numerous super- 
posed layers. M. Pergens included in the genus one of the two 
species of d’Orbigny ’s Meandrocavea, a suggestion which seems to 
me justified.
