certain Agnathous Pulmonate Mollusks. 71 
The vagina is considerably larger than in P. Hochstetteri ; 
at its extreme distal end a short sessile receptaculum seminis 
is seen. The free oviduct is very short and arises latero- 
dorsally on the right side, passing in an oblique direction 
forwards. The common duct is a long, almost straight, 
double tube. The remaining organs call for no special 
mention. 
Until more species of this genus have been anatomically 
examined any comparisons are of little value. P. Edwardi 
is very distinct from P. Hochstetter’ so far as the generative 
organs are concerned, though it is very probable that there 
exist intermediate species which would connect the two.

Animal (in alcohol) brownish yellow, darker on the dorsum, 
posteriorly and latero-posteriorly splashed with irregular 
black markings. Dorsum marked by two parallel lines 
running from the anterior edge of the mantle to the head, 
and well-marked lateral grooves running from the mantle to 
the lips. Posterior to the mantle the visceral mass slightly 
overhangs the tail-region. No caudal mucous pore. Respi- 
ratory orifice in the antero-lateral margin of the mantle. 
Ruge large, ill-defined laterally. Sulci almost black. Peri- 
odial groove indistinct. Foot-fringe yellow, with greyish- 
yellow lineoles. Foot-sole greyish yellow, with faint trans- 
verse wrinkles, not divided into median and lateral planes, 
Length (in alcohol) 25 millim., foot-sole 8 millim. broad. 
Hab. Near Stratford, North Island, New Zealand. 
The genus Schizoglossa was constituted by Hedley in 1893 * 
for the reception of the Daudebardia novoseelandica of Pfeiffer f. 
The species was originally described from the shell only. 
Hedley (op. czt.) was the first to give a description of the 
animal and its structure and to figure the same and shell ; he 
therefore must be regarded as the authority for this species,
