80 Miscellaneous. 



Sciences of Brussels describing the pelvis of Cetacea. He has de- 

 scribed and figured the femur and tibia of the Greenland Whale ; 

 thej are both rudimentary, and somewhat similar to the rudimen- 

 tary femur observed by Mr. Flower when describing the Tinner 

 Whale {Phy solus). 



On a remarJcahle Form of Pleuronectidse from the Mediterranean. 

 By Dr. Steindachnee. 



This fish, described under the name of Apionichthys Ottonis, has 

 rndimentary, 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 5| times, the 

 depth of the body 3| tinles, and the caudal 4^- 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 cler Akacl. der Wiss. in Wien, May 22, 1868,

On the Antherozoids of the Mosses. By E. Roze. 



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 Polytrichacea) (Atrichum, Fogonatum, Folytri- 

 clium), still contained in their mother cells, and upon the free an- 

 therozoids ofBryum capillare oxidi pseudotriquetrum, Mniiim Jiornum, 

 and Hypnimi cupressi forme. — Comptes Mendus, tome Ixvi. June 15,
