80 Miscellaneous. 
Sciences of Brussels describing the pelvis of Cetacea. He has de- 
scribed and figured the femur and tibia of the Greenland Whale ; 
they are both rudimentary, and somewhat similar to the rudimen- 
tary femur observed by Mr. Flower when describing the Finner 
Whale (Physalus). 
On a remarkable Form of Pleuronectidee from the Mediterranean. 
By Dr. SrerpacHner. 
This fish, described under the name of Apionichthys Ottonis, has 
rudimentary, punctiform eyes, a short, fissure-like branchial aper- 
ture, and a long pointed caudal fin, into which the dorsal and anal 
gradually pass. The length of the head is contained 53 times, the 
depth of the body 34 times, and the caudal 41 times in the total 
length. On the blind side of the body the ventral is wanting. The 
lateral line passes through 87—90 scales; the dorsal contains 70-73 
and the anal 52-54 rays. On the upper margin of the lower lip 
there are 16-17 cilia, but only on the eye-bearing side of the head. 
The nasal orifice on the blind side of the head is dilated into a disk, 
and lobed.—Anzeige der Akad. der Wiss. in Wien, May 22, 1868,

On the Antherozoids of the Mosses. By E. Rozr. 
The author’s first investigations on the antherozoids of the Mosses 
led him to express the opinion that these organs are composed of a 
biciliated filament with two spiral turns, to which a mass of amyla- 
ceous granules adhered, but only during their motility. In the 
spring of this year he ascertained that these granules, instead of 
being affixed directly to the spiral, are contained in a hyaline plas- 
mic vesicle, which is attached to the filament by a sort of tangential 
adhesion. 
Under a power of 1500 diameters, this vesicle is clearly discerned, 
both by its spheroidal outline and by the very brisk molecular move- 
ments of its contents. It swells in water immediately after the 
quiescence of the ciliated spiral; then it suddenly bursts, and the 
amylaceous granules continue in the liquid the lively molecular tre- 
pidation which seems normally, in the vesicle, to coincide with the 
cessation of the ciliary movement. 
Except as regards the existence of this vesicle, the facts previously 
indicated by the author are by no means modified. From this new 
fact it appears that the antherozoids of all classes of Cryptogamia pre- 
sent not only an organ of locomotion, but also a vesicular appendage 
filled with a plasmic liquid suspending either non-analyzable grains 
or amylaceous granules. This fact was foreseen by M.A. Brongniart. 
The author’s recent observations were made upon the antherozoids 
of various genera of Polytrichacee (Atrichum, Pogonatum, Polytri- 
chum), still contained in their mother cells, and upon the free an- 
therozoids of Brywm capillare and pseudotriquetrum, Mnium hornun, 
and Hypnum cupressiforme.— Comptes Rendus, tome lxyi. June 15,
