 example has been followed by many observers, hence 

 the records of this species are disproportionately

found in which E. ciliata is the prevalent species ; in 

 its larger forms it is distinguished from E. compressa 

 by its oval transverse section, denticulated aperture- 

 scales, and its smaller body-scales; small glabrous 

 individuals are distinguished from E. Isevis by the 

 denticulated aperture-scales (fig. 124) and larger and 

 more broadly-oval body-scales (fig. 123). The ellip-

tical aperture distinguishes it from E. strigosa which 

 invariably possesses a' circular one. Tests of that 

 species which have been slightly crushed accidentally 

 can usually be identified by the thickened aperture- 

 scales, but if these, as may rarely happen, are of the 

 same thickness as the other scales of the test, and there 

 is no trace of a neck, such crushed tests of E. strigosa 

 cannot be distinguished from those of E. ciliata. This
