monstrosity and named it Dimorphina millettii {Q. i9i8,FECA,p. 145, pi. v, figs. 13, 14). 

 We think this was a mistaken view, although Cushman and Ozawa accept the name in 

 their recent monograph (tit supra). None of the figured individuals are identical as 

 regards the exact position and size of the accessory chamber. In the Falkland Islands 

 specimens the accessory chamber, instead of being attached to the apex of the shell, 

 projects from the side of the final chamber, and, although itself furnished with a distinct 

 aperture, connects with that chamber by absorption of the intermediate walls, and not 

 through the oral aperture of the terminal chamber. At WS 408 a specimen, 0-4 mm. 

 long, which is presumably megalospheric. It has only three chambers including 

 the proloculum, which occupies about one-half of the entire test.
