Measurements. — Apertureu 



^ Ua = 0.08 mm. 



„ . jLz = 0.50 mm. 

 U2 = 0.42mm. 

 Variations. — The measurements are quite variable, those we give 

 being the greatest. There are five distal spines. The zooecial def- 

 ormations are frequent and quite great. The operculum closes the 

 ovicell. In front of the aperture there is a small mucro with a 

 minute pore on each side conforming to the figures of Smitt. This 

 is the distinctive characteristic of this form, which is very rare. It 

 is somewhat larger than the form innominata Couch, 1844. It does 

 not correspond altogether to Puellina radiata as Norman, 1909, lim- 

 ited it, for this author indicates the inconstant presence of a lunate 

 pore before the aperture. 



Biology. — Our specimens encrust corals. They were in reproduc- 

 tion and fixation May 1, 1884.
