274 QUARTERLY CHRONICLE. 
from the trunk are openings leading into this internal canal, 
which constitutes, as it were, a continuous canal-system. The 
canals open in spoon-shaped slits at the extremities of the 
branches. 'The canal seems to be formed by the union of the 
borders of an originally simple flattened lamella or riband. 
The polype-cells are circular, and are placed in rows, 
which are so disposed that the middle line of each branch is 
left free. The cells are often closely crowded in these rows, 
especially at the upper part of the stem and at the ends of 
the branches. 
The species is thus characterised:—Stem somewhat 
flattened, slightly flexible, solid, pervaded by nutritive 
canals. Branches and ramules furnished with lateral flat 
appendices, which, except at their commencement and end, 
are so grown together that the branches and ramules appear 
to be hollow. Polypes disposed in two series, which leave 
the underside and middle line of the branches and ramules 
above, free. Each polype is seated in a more or less well- 
defined eight-rayed disc or cup. ‘The interior of the entire 
ceenecium, pervaded by nutritive canals, with the exception 
of an ill-defined slender axis which is found in the branches. 
The spicula, except in this axis, free. An imperfectly deve- 
loped horny substance occurs in places in the central parts of 
the whole ccencecium. 
The systematic position of this new and curious genus, he 
says, is obviously among the Gorgonide, and in the family 
of the Briareaceze of M. M. Edwards. 
5. “On the Ganglion-cells of the Spinal Chord,” by 
Friedrich Jolly— The author’s observations were prompted 
principally with a view of examining the results arrived at 
by Fromman,* and by Deiters.t And they were instituted 
chiefly on the cells of the anterior cornua of the chord; which 
on account of their greater size afford the best characters for 
observation. 
“It is of the greatest importance,” he observes, ‘in an 
inquiry of this nature, to examine the chords of various 
animals besides man, inasmuch as the cells even from corre- 
sponding parts differ enormously. As regards the human 
subject the chord of the newly born infant is to be pre- 
ferred.” Here follows the mode of preparation recommended 
by Deiters (1. c. p. 1—26). The author considers that sections 
of hardened preparations are almost inapplicable for the study 
of the ganglion cells, owing to the changes produced in those
