Howes, G. B. Rabbit with an Intranarial Epiglottis, with a Suggestion 
concerning the Phylogeny of the Mammalian Respiratory Apparatus. 
J. Anat. Phys. xxiii, pp. 263-272, woodcut. 
Describes two instances of this abnormality in the Rabbit, and records 
cases of its occurrence in other groups of terrestrial Mammals. Suggests 
that it may be a reversion to an aucestral type.

Observations on the mode of formation and structure of the Wolffian 
bodies in the Rabbit. 
Masius, J. De la Genese du Placenta chez le Lapin. Bull. Ac. Belg. (3) 
xvi, pp. 317-325. 
The author concludes that the placenta of the Rabbit is of foetal origin, 
formed by the allantoid villosities which ramify in a tissue derived 
entirely from the epiblast of the embryo, and that the maternal blood 
consequently circulates in a mass of epiblastic tissue of foetal origin. 
Ryder, J. A. Vestiges of Zonary Decidua in the Mouse. Am. Nat. xxi, 
pp. 1037 & 1038. [Omitted from Zool. Rec. xxiv.] 
The data seem to show that the primitive type of placentation was 
more diffuse than in existing Myomorphous Rodents, and throw light on 
the derivation of a discoidal from a zonary placentation.
