Gregory has figured the ovicell of this species, ^yc have not been 

 fortunate enough to discover the oeciostome. This ovicell is fusiform 

 much elongated and always near the zoarial margins. 



Geological distribution. — To the localities cited by Gregory it is 

 necessary to add the following French localities from the Canu col- 

 lection. Turonian at Duneau and Connerre (Sarthe) and Fontaine 

 d'Antoigne near Chatellerault (Vienne) ; Coniacian at Les Phelip- 

 peax (Charente), Tours (Indre-et-Loire), and Fecamp (Seine Tn- 

 ferieure) ; Santonian at Piaud (Charente) and Eomorantin (Loir-et- 

 Cher) : Campanian at Montomoreau (Charente) ; Maastrichtian at 

 Deviat (Dordogne) ; Rocanian of Argentina. 



DIAPEROECIA TURONICA, new species. 



Plate 8, figs. 1-6. 



Description. — The zoarium is a bushy Mesenterlpora composed of 

 undulated and distorted lamellae on which the peristomes are ar- 

 ranged in quincunx or in oblique lines, as in ReticuUpora. The 

 tubes are visible, almost flat, straight, bordered laterally by two very 

 thin threads hardly salient : the apertura is elliptical, the peristome 

 is thin and little salient. The zone of growth is wide and visible. 

 The ovicell is large, globular, quite convex, elliptical, perforated by 

 as manj^ as 15 peristomes. 



Diameter of peristomes 0.12 mm. 



Measurements. — Distance between peristomes — 0.50-0. 64 mm. 



Separation of peristomes .30- .44 mm.
