I. On some specimens of the Birkelänge [Molva ahyssorum, Nilsson) from Ice- 

 land and Faroe. It might well be descended from a parent stock not greatly differ- 

 ing from the common Ling {M. vulgaris). — II. On the recessus orbitalis, an ac- 

 cessory visual organ in Pleuronectid Fishes. Its function is simply to protract 

 the eye and to regulate its vertical movements. — III. On an adult specimen of 

 the Common Sole [Solea vulgaris Quensel) with symmetrical eyes, with the discus- 

 sion of its bearing on Ambicoloration. The left (commonly blind) side is colourless, 

 so that the ambicoloration cannot be held to depend on the mere arrest of the 

 migration of the eye. The skull presents all the characters which one finds in 

 a specimen in which the usual migration has taken place.

Mesodermal. The apparent disappearance of the basement membrane is due 

 merely to the obliquity of the plane of section. The splitting off of the lower 

 layer of the ectoderm is due to the resistance offered to the section-knife. (Against

L'auteur a traité les points suivants: la structure des lobes antérieurs, l'origine 

 des fibres du pédoncule cérébral, l'origine et la terminaison des fibres du faisceau 

 de Meynert ou rétroréflexes, éléments constitutifs des lobes optiques, origine et 

 terminaison des filets olfactifs, origine de l'oculo-moteur, du facial, origine et 

 terminaison périphérique et central des fibres du nerf acoustique, éléments con- 

 stitutifs du ganglion de Casser et du ganglion sur le trajet du nerf pneumo-gastri- 

 que, et comme les fibres sensitives de ces deux nerfs se comportent à leur entrée 

 dans le tronc cérébral.

The first indication is a thickening of the ectoderm close to neural canal. Me- 

 soderm tissue begins to separate it from the olfactory lobe. The nerve connects 

 it with this. The ciliated epithelium appears and »the interior part of the epithe- 

 lium has developed into an olfactory one with plenty of nerve cells«.
