braiichlct, while, as remarked by 

 Kent in reference to his supposed 

 bi-tripartite variety, the termination 

 of each branchlet bears a considerable 

 number of collared /ooids. 



Allied to what I therefore consider 

 the complete and mature form of C. 

 iimhellata is a hitherto undescribed 

 colony of the same genus, whose 

 truly splendid aspect seems to demand 

 recognition in the specitic name ?nag- 

 nlfica. Its main stem is considerably 

 longer than that of C umhcllata and 

 bears just twice as many primary 

 branches, each of these being furcated 

 and each of these secondar\' l)ranches 



tion between it and other somewhat 

 similar forms : 



Codosli^a magnijica^ sp. nov. 



Main stem bearing umbellately eight 

 rigid, straight branches about one- 

 half its own length, and bifurcated, 

 each of the secondary branches sub- 

 dividing into four branchlets, the 

 summit of each of which usually sup- 

 ports two zooids resembling in form 

 those of C. iimbeUata : main rachis 

 ten to fifteen, the primary and sec- 

 ondary branches four to six, and the 

 branchlets two to four, times as long 

 as the body of a single zooid. Height 

 of pedicel, exclusive of the bodies. 



giving origin to four branch- 

 lets every one of which usual- 

 ly supports two zooids, rarely 

 more, except during repro- 

 ductive fission. The entire 

 formation, even exclusive of 

 the animalcules, is the largest 

 yet recorded, being easilv dis- 

 tinguishable with so low a 

 magnifying power as that of 

 the one-inch objective. The
