tlie orifices are gi'anulated. Ooecia are absent. The vibraculte are very 

 pleutifnl and issue from small vibracular chambers situated between 

 neighboiuing zooecia. The flagella? are very long and golden, and are 

 directed upwards and sideways, lying against the surface of the polyzoary.

Polyzoary. — A strong discoid grcnvth 11 mm. in diameter and from 4 

 to 5 nun. in height. The zooecia, airanged in radiating rows, are super- 

 ficial and occupy the outei" surface. The basal oi' inner surface is smooth, 

 though decorated witli occasional radiating lines of minute punctations, 

 which can be seen under a microscope. A ci'oss section of the polj'zoary 

 shows the zooecia to be remarkably shallow and superficial ; the structure 

 other than these is entirely made up of fibrous calcite. The greatest 

 thickness, that is at the apex, is 25 inm., and this slopes evenly to a 

 thickness of 1 mm. at the edges. 



l)'ia(iiiosis. — The zooecia ai-e roundly quadrangular and are covered 

 with a yellowish depressed ciyptocyst, tlie distal borders of which are 

 overlapping. They aie arranged in a radiating series of tliirteen from 

 the apex to the edge. The oiifice is minute and is orbicular in shape. 

 Oo-cia are absent. Vibiac\il!v aie very plentiful, and small ciicular 

 vibracular cells are situated betweei\ the zoo^cial rows over the entire
