The vagina is considerably larger tliari in /'. Iluchstetteri; 

 at its extreme distal end a short sessile roceptaciilum seminis 

 is seen. The tree oviduct is very short and ari.scs latero- 

 dorsally on the right side, passing in an oblique direction 

 forwards. The common duct is a long, ahnost straight, 

 double lube. The remaining organs call tor 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 V. HocliHtetteri so far as the generative 

 organs are concerned, though it is very probable that tliere 

 exist intermediate species wliicii 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 

 vuiniing from the anterior edge of the mantle to the head, 

 and well-marked lateral grooves running from the mantle to 

 the lips. l*osterior to the mantle the visceral mass slightly 

 overhangs the tail-region. No caudal mucous |)ore. Respi- 

 ratory orifice in the antero- lateral margin of the mantle. 

 Rugaj large, ill-defined laterally. Sulci almost black. Pcri- 

 podial groove indistinct. Foot-fringe yellow, with greyish- 

 yellow lincoles. Foot-sole greyish yellow, with faint trans- 

 verse wrinkles, not divided into median and lateral planes. 



Length (in alcohol) 25 millini., foot-sole 8 milliin. broad. 



Hab. Near Stratford, North Lslund, New Zealand. 



The genns Schizoglossa was constituted by Hedley in 1^1)3 * 

 for the reception of the Daudebardia novoseelandica of Pfeiffer f. 

 The species was originally described from the shell only. 

 Hedley [op. cit ) was the first to give a description of the 

 animal and it.-* structure and to figure the same and shell ; he 

 therefore must be regarded as the authority for this species.
