Manzoni, in a paper upon the Italian Pliocene Polyzoa {Briozoi 

 Fliocefiici Italiani) recordsi in the reference quoted, the occur- 

 rence of this species in Italy. I have not seen the reference to 

 " Lethaea Rossica, ' which Manzoni quotes in his paper. 



The following is a translation of the principal part of 

 Manzoni's description: — ''Cells (zooecia) quincuncially disposed, 

 rhombic-ovate, rounded distally, partly punctate ; aperture ter- 

 minal, semicircular or subrotund ; peristome elevated, six spines 

 above. Three thick smooth costae, central one attenuated to- 

 wards the base, lateral ones divergent, surface between the 

 costae irregularly jjunctate, moderately convex, depressed to- 

 wards the base." He states the cells (zooecia) are very large, 

 the dimensions being — height 1 mm., width two-thirds of a 

 millimetre. 



Locality. — Campbell's Point (J. F. Mulder). 



The specimen of this species is upon a slide given to me by 

 Mr. Mulder. It is only an imperfect front wall of a zooecium ; 

 it agrees in every respect with Manzoni's description and figure, 

 but only the central costa is present, the lateral ones have been 

 broken off. It is 0.8 mm. long, and if perfect would have been 

 quite 1 mm. long, if not more. The punctations are mostly 

 small hemispherical pits, with a pore in the centre, but in one 

 pai-t they are crowded and quadrate in shape, and there are 

 traces of the six spines on the upper margin of the peristome. 



Inversiula airensis, n. sp. (PI. XLVIIL, Fig. 38). 



Zoarium encrusting. Zooecia ovoid, surface roughly granu- 

 lated. Tliyrostome transversely elliptical, with the proximal 

 margin more curved than the distal one : a short spinous pro- 

 cess, perforated at the summit, on each side below the thy- 

 rostome. 



Locality. — Wilkinson's Xo. -t. Aire coastal beds (Dr. Hall). 



This species is very near /. nutrir, recorded by Jullieni, but 

 it has not the central " fenestrule semilunaire " of that species.
