connate, ag-gregated into fasciculi, and continuous throughout the 
length of the fasciculus, at the extremity of which only they open ; 
wall of cells porous ; no intermediate pores or cancelli. Busk. Brit.

The family are represented by two Genera. 
IG. — Truncatula sp. (T. repens ? Hag. d. Bryoz. Kreid., pi. III., 
fig. 1,) 
Truncatula Uagenow {Idi)ionea sp. of authors.) 
Only one poor specimen of this genus was found in the Jesson 
material. 
Localities: Cambridge, Greensand; Faxoe Limestone ; Maestricht, 
Falkenberg (Hagenow.) 
The following peculiar Genus has been founded by D'Orbigny 
for the placement of Fossils called by MicheHn Pelagia and Idmonea 
(I. aculeata Mich.) Novak has adopted the Genus for his work on the 
Bryozoa of the Bohemian Cretaceous series, and the British forms 
are related to his, rather than to D'Orbiguy's Osculipora. 
Genus OSCULIPOEA, D'Orb.

Bohm. Kried. p. 112, Tab. X. f. 16-34. 
Forms, evidently belonging to this species, are very abundant 
in the Cambridge material. These are generally found as simple, 
and much branched. While some few of the specimens in the 
Jesson collection may be referred to as the bases of species of 
Entalophorse, others are undoubtedly species of the Frondiporidee of 
Busk, and Osculijyora may be related to Fasciculipora if not a true 
member of the Genus. Fasciculas few in number.
