even higher than wide. In profile, however, they are seen to be longer than the typical 

 form, and present sundry crests and grooves. Ophioglypha bullata heads an aberrant 

 group which in some points approaches Ophiomusium, to wit, in the closely joined 

 radial shields ; the very long and spreading mouth frames, with a broad, regular, 

 uncovered nerve ring ; the massive and closely soldered disk plates, and the regular and 

 less club-ended genital plates. (See PI. XXXVIII. figs. 10-13, 14-17, 22-25.)
