makes a bend to the left side and then dips down into a cavity 
bounded by the pedal muscles. To this portion the short 
retractor muscle is attached on the right side (PI. LI. fig. 21). 
Paryphanta Edwardi, Suter. (PI. IL. figs. 22-25.) 
Animal a deep blue, darker laterally than on the dorsum. 
Mantle greyish white, with very fine sepia markings on the 
collar, which is divided asin the genus A/ytida. Generative 
orifice 85 millim. from the right upper tentacle. Ruge 
irregular, very small posteriorly. Sulci bluish white. Peri- 
podial groove ill-defined, Foot-fringe bluish white and finely 
spotted, no lineoles. Foot-sole sepia-coloured, with a tinge of 
blue in the median portion, not divided into median and 
lateral planes. 
Length (in alcohol) 43 millim, 
The shell and radula of this species were described by 
Suter in 1899 *, It differs considerably from the preceding 
species. Suter regards it as standing nearest to P. atramen- 
tarta, Shuttl., from Victoria, a species I am unacquainted 
with. 
Anatomy. 
The Alimentary Canal.—The buceal cavity calls for no 
special mention. ‘The cesophagus enters on the dorsal surface ; 
tracing this posteriorly it widens a little, forming the crop, 
around which the salivary glands are closely wrapped; the 
ducts leave the anterior borders and enter the buccal mass at 
the side of and just behind the cesophagus. Behind the crop 
there is a thin tube-like portion of the canal, which again 
widens before reaching the stomach. 
The Fedal Gland (PI. II. figs. 23, 24) is very similar to 
that in P. LHochstettert, Pfr., differmg, however, in its greater 
length, measuring in setu 24 millim., and in turning forwards 
and downwards to the left side. Imbedded in the pedal 
muscles and quite distinct from this gland is a small glan- 
dular body like that found in Rhytida Greenwoodi, Gray. 
The Generative Organs (Pl. Il. fig. 25).—On turning 
back the body-wall the penis is seen to lie in a very similar 
osition to that in P. Hochstetter?. It measured 58 millim. 
in length. It is an almost straight tube, widening in the 
distal half. In structure it is similar to that in the preceding 
species. Being larger the vas deferens is easily made out 
fiom the left side of the distal end of the penis to the union 
with the prostatic canal. It is a simple tube not convoluted.
