16 MR. A. W. WATEES ON 



A specimen of Eschara Egcea, d'Orb., from Royan has similar 

 larger ovicelligerous cells. 



Log. Several Miocene localities in Austria and Hungary. Val di 

 Lonte ; Erendola ; Montecchio Maggiore ; Ferrara di Monte Baldo ; 

 Bonzo ; Crosaro ; Priabona ; Malo ; Gotzreuth (KoscJi.), Latdorf ; 

 Wola Lu'zanska ; Astrupp (Miocene), Pianosa (Miocene). 



24. Ceibeilina eadiata (Moll). 



There is considerable variation in the appearance of various 

 specimens, caused by difference in the number of costse ; and in 

 some cases vicarious avicularia are present ; also some specimens 

 from Yal di Lonte and Brendola have the lower lip somewhat 

 raised, and at each side of the aperture there is a small avicularian 

 or vibracular opening, giving the appearance of C. puncturata of 

 Eusk, 



The pores between the costae are more numerous than in C. 

 Ilaueri, Eeuss, though, when crushed, they look like Eeuss's 

 figure 16, pi. xxxii., which he calls E. Ilaueri, but I have only seen 

 this shape of zooecia in incrusting forms ; and stems of other 

 Eryozoa are often so completely covered that without careful 

 examination they might be taken for erect specimens. 



Log. Living: Cosmopolitan. Possil : Yal di Lonte; Erendola;

25. Cribeilina chelts, Koschinsky. (PI. II. fig. 10.)

 siidl. Eayerns, p. 36 ; Pergens, Eryoz. von Wola Lu'zanska, p. 70. 



There is a large oval avicularium at one or both sides of the 

 zooecium, and the large pores around the area are irregularly placed. 

 What Eeuss described as the large pore above the aperture is an 

 avicularium, that of one zooecium often being situated above the 

 aperture of its neighbour. There are also a few very large vicarious 

 avicularia. The ovicell is very large, but slightly raised, and has 

 an irregularly perforated area on the front, and reminds us of the 

 ovicell of Lepralia oGclusa, E. The ovicell and vicarious avicula- 

 rium are added to fig. 10 from different parts of the colony. There 

 is considerable difference in the appearance of various parts of the 

 colony, as in some parts the avicularia are very numerous, but 

 elsewhere absent, and there are sometimes irregular pores at the 

 side of the zooecium ; but in no case have I seen the regularity 

 figured by Eeuss, and probably a worn specimen was examined, 

 and then the artist used his imagination. I have specimens 

 incrusting other objects in a single layer ; but, as a rule, there are 

 several layers superimposed.
