92 CLASS II. 
Sp. Minyas cinerea Cuv. R. Ani. 1° edit. Pl. xv. fig. 8, Lesson Centurie 
Zool. Pi. ux. fig. 1, in the Atlantic Ocean. This genus is referred by 
Cuvier to the Lchinodermata apoda ; Lrsunur, who has made known some 
other species of it, gives it a place near Actinia. An accidental, not a 
natural opening in the disc, opposite the mouth, was taken by Cuvier for 
anus. See the 2nd edition of LAMARCK, Hist. nat. des Anim. sans vertébres 
Ill. pp. 427—429. 
Lucernaria Murti. Body gelatinous, radiate, the rays tenta- 
culiferous at the tip, above flattish, with mouth central, funnel- 
shaped, protracted, below elongated into a pedicle disciform at 
the extremity.

Comp. on this genus Lamouroux, Mém. du Muséum, U. pp. 460—471. 
Pl. xvi. Does it belong here? Lamarck refers this genus to the Acalephe. 
Edwardsia QuATREF. Body free, cylindrical, rounded behind. 
The middle portion of the body with thicker epidermis, opaque ; 
the anterior and posterior pellucid, retractile within the middle. 
Mouth furnished with tentacles,. hollow, arranged in single or 
double row.

xvilt. Zool, Pl. 1. fig. 1, &e. 
These remarkable animals, discovered by QUATREFAGES, live on the sea- 
shore in the sand, like Sipwnculus and some Annulata. The tentacles are 
not perforate at the extremity, as little as they are so in Actiénia, in which 
preceding authors (Rapp, RyMER JONES and others) admit a reception of 
water through the presumed apertures. 
Orprer IV. Bryozoa. 
Y 
Nutrient canal supplied with double aperture (mouth and anus), 
replicate, the posterior portion ascending by the side of the anterior. 
Tentacles long, furnished with vibratile cilia, surrounding the 
mouth. The anterior part of the polyp soft, retractile within the 
posterior by mversion. 
EHRENBERG was the first to separate with precision these animals 
see the Introduction to this 
class. Minne Epwarps makes of them, in company with the 
Acephala nuda, a division of the type of the Mollusca under the 
name of Jolluscoides. As in our first order of Polyps we see a 
resemblance to Acalephe or Medusz, in the second recognise the 
from the other forms of the Polyps 
proper type of the Polyps, and in the third perceive a transition to
