with shorter marginal grooves between them, giving the edge of the 
foot a crenated appearance ; ; the end of the body becomes suddenly 
more slender, with a prominence on the back just before this sudden 
alteration, as if the mass of the viscera were confined to the first 
two-thirds of the body ; but this may be caused by the contraction of 
the animal from being in spirits. 
Shell none, or at least there is no appearance of any through the 
skin. 
JANELLA ANTIPODARUM. 
Hab. New Zealand. Length three-fourths of a inch. 
This genus is most nearly allied to Philomycus (=Tebenophorus, 
Binney=Limacella, Blainville), with which it agrees in having a thin 
mantle covering the whole of the back; but it differs from it in the 
position of the respiratory aperture, and in the presence of only two 
tentacles, which, instead of being placed on the head, as in Philo- 
mycus and all the other Arionide and Helicide, are placed in the 
front part of the mantle. All these characters induce me to regard 
it as the type of a new family of Pulmonata, which may be called 
Janellide. 
3. On THE ATTITUDES AND FicureEs or THE Morse. 
By J. E. Gray, Pu.D., F.R.S., V.P.Z.S. 
The arrival of a living Morse, or Walrus, in this country, show- 
ing that it is very different in its manner of moving from the Seals, 
has induced me to examine and compare the figures which have 
hitherto been given of this animal. Most of the oldest figures were 
purely imaginary. To this series must be referred the Rosmarus and
