Asexual reproduction .seems to take place b\' one corner of the calice hcconiing 

 elongated. The ])rojecting portion may be of small diameter, then its diameter 

 increases to almost the size of that of tlie mother calice. The two calices are 

 subse((uently separated bj^ tission. 



Wall rather thick. Costw corresponding to all septii, e()ual, broad, rounded, and 

 ornamented with minute, crowded granulations. 



Septa in specimens Nos. 2 and 3 of the table (wliicli appear to be as large as the 

 specimens usually grow before division begins), 32 in number, i. e., there are three 

 complete cycles and some members of the fourth. Specimen No. 5 has 35 septa in 

 all. The dirt'erent cycles are not well diflerentiated; it is practically impossible to 

 distinguish l)et\veen the first and second cycle. In general the members of the, first 

 cj'de do not form parts of septal groups, while the members of the third bend 

 toward those of the second. The members of the first and second cj'cles are of the 

 same size, and when members of the fourth cycle are present the neighboring 

 members of the third equal in size those of the preceding cycles. Around the edge 

 of the calico the septa appear alternately larger and smaller, the last c\'cle alwaj^s 

 being smaller and having less prominent margins. Margins of the larger .septa 

 moderatelj' exsert; the exsert and inner portions of all septa thin. Septal faces 

 beset with crowded, tall, rather sharp-pointed, slender granulations (really delicate 

 spines). 



Pali before all septa, except the last cycle, in one or two crowns, sometimes 

 showing a tendency to unite the septa into deltas, as in iKUncijuflnix. They are 

 rather wide, very thin, and are granulated in the same fashion as the septa. 



Columella terminated above by several .stout papilla?, whose ends arc minutely 

 granulated.
