served, one in Avhich the particles of the test are small and the test 

 smoothly finished, the other using larger grains and consequently a 

 rougher surfaced test. As the specimen develo])s it becomes more 

 nearly spherical and the nipplelike apertural neck becomes apparent. 

 A variety of tliis species from the Faroe Channel is noted. It 

 has a very rough test using "large tetractinelUd spicules as a support- 

 framework for the shell.'" Usualh' tlicsc have no protuberant neck, 

 "the aperture being usually an irregular and large opening, nearly 

 flush with the slicll wall and lined with pale cement." This variety, 

 apparently worthy of varietal rank, may ])e known as Saccammina 

 sphaerica, var. anglica, new variety. It is plate 1, figures 15-19, of 

 Heron-Allen and Earland's paper in the Journal of the Royal 

 ^Microscopical Society for 1913.
