54 THE CRAG POLYZOA. 



Cells ovate, contracted at top, surface smooth ; a single row of minute punctures 

 around the border of the cell ; orifice subquadrangular or oblong, transverse ; peristome 

 produced, entire, thick ; a broad tooth within the lower border. 



Habitat.— C. Crag, S. W. 



27. L. iNFUNDiBULATA {n. sp.) Plate VIII, fig. 4. 



Cellulis ovato-ventricosis ; orificio oblongo, transverso ; peristomate integro, valde 

 producto sive expanso. 



Cells ovato-ventricose ; orifice oblong, transverse ; peristome entire, much produced 

 and expanded. 



Habitat.— 'Red Crag, on shell, S. W. 



This may prove to be only a variety of L. Beussiana, though presenting some apparently 

 strongly distinctive characters, such as the absence of the marginal puncta and of the 

 oral denticle. From L. labrosa {Alysidota labrosa), Busk ('B. M. C.,' pi. xcii), it appears 

 to be distinguished; not only by its habit, but also by the smoothness of the surface, and 

 the circumstance that the peristome is entire posteriorly. 



28. L. PALLASIANA, MoU. PI. IX, fig. 7. 



Cellulis ovato-ventricosis, superficie puncturatis, subinde verrucosis. Orificio supra 

 arcuato, medium infra coarctato ; peristomate simplici, incrassato ; labio inferiori recto, 

 nitegro. 



Cells ovato-ventricose, surface punctured, sometimes verrucose ; orifice arched above, 

 contracted below the middle ; peristome simple, thickened. Lower lip straight.
