Description. — Test subspherical, smooth, aperture either stellate or 

 a fissure with an entosolenian neck, wall thin, usually transparent, 

 but sometimes thicker and nearly opaque, white. 



Length about 0.35 mm.; breadth usually a little less. 



Distribution. — This species seems to be a cosmopolitan one and is 

 well distributed in the North Pacific as elsewhere. Nearly all the 

 stations are in deep water, but a few are in shallow depths and near 

 shore in the case ol the record of Rhumbler off the Chatham Islands 

 and Brady from the coral reefs of Honolulu. 



A great many very variable figures are found if one looks up the 

 synonymy of this species. According as the author's idea of variation 

 has been restricted or loose the number of things put here varies. 

 Perhaps the worst example of the latter is that of Parker and Jones. 1 



1 Ann. Mag. Nat. Hist., ser. 2, vol. 19, 1857, pi. 11, figs. 25-29, where four figures referred to this species 

 are four distinct species not one of which can be in any sense truly referred to this species with a smooth 

 test. Brady's specimen from the Silurian as figured might be fully as well and perhaps better some form 

 of Difflugia than Lagena globosa. 



Balkwill and Wright, 1S85, make note of two forms occurring in their material, one with a stellate aperture 

 the other with a fissure. With a large collection of material various forms would doubtless be found which 

 are perhaps of varietal rank and definitely distributed.
