Not illustrated. 1904 Excerpt: ...unbranched, with several deep annulations on the proximal end, and regular short internodes, each bearing a hydrotheca and usually several annulations; nodes very deeply cut and oblique. Hydrothec not contiguous, barrel-shaped, ornamented with four to six annular rugosities, ending in a short ill-deiined square collar; margins square, with four ill-defined teeth and a four-flapped operculum.

SERTULARELLA AREYI, new species. (Plate XVII, flg. 6.) Trophosome.--A fragmentary specimen was ail that was secured. It was about one-fourth of an inch high. Stem unbranched, very slender, internodes longer in proportion to theirthickness than any others of the genus that I have seen, each bearing a hydrotheca near its distal end. Hydrothec barrel-shaped, very distant, margin square with four obscure teeth and a fourflapped operculum; hydrothecal body marked by two very distinct annular rugosities which divide the body into three nearly equal zones. The surface is further ornamented with distinct longitudinal lines or fine ridges. Gonosom e.--U nk no w n. Distribution.--Dredged nea...
