CIIILOSTOMATA. Cell-opening or mouth closed with a movable 

 lip or operculum. Ayicularia and vibracula mostly present. 



Glaus divides this suborder into four groups : a. Cellularina, 

 zooecium corneous, funnel-shaped: ^Eteidse, Cellulariidae, and 

 Bicellariidse. b. Flustrina, zooecium quadrate, smooth exter- 

 nally : Flustridae, Cellariidas, and Membraniporidae. c. Escharina, 

 zooecium mostly calcareous, quadrate or semioval, with a lateral 

 opening : Eschariporidaj, Myriozoidse, Escharidae, and Discopo- 

 rids=e. d. Celleporina, zooecium calcareous, rhomboid or oval, 

 with a terminal mouth : Celleporidas and Reteporidse. For 

 Schmarda this and the two following groups rank only as 

 families. Hislopia is an aberrant Indian freshwater form.
