0/;,s'. — No examples of tliis species wi're in the colleotions of the 

 Australinii Museum, and only a lew were collected hy the author, Mr. John 

 Hiazier, who at later dates could not find further examples. From hJH 

 statements it would seem probable that the types and co-types were 

 dissected by vou Lendenfeld, as a result of wliich his paper was written. 

 1 collected two specimens in June 1918, one of which becomes the meta- 

 type in the collections of the Australian Museum. 



Ainttoiin/. — Opened from the dorsal surface the viscera is seen (PI. 

 xxxviii., tig. 1) compactl}'^ massed in a well defined mantle cavity; tlie 

 anatomy does not possess any extra-ordinaiy featuies compared with the 

 described anatomy of other species of this genus. 



Aliwenfari/ si/nti'in. — The mouth is two mm. in length formed by 

 lounded lips. The bulbus pharyngeus is strong and large, flattened on tlie 

 lower side and otherwise rounded. Tlie radula is deep brown in colour, 

 a!id the dental formula diffei's with its shape ; a complete anterior row 

 having 90 : 1 : 96 while the central and posterior rows liave 1:56 : 1 : 136

(Fig. 1). There is no definite jaw hut strong dagger shaped palatal 

 plates are present. The oesophagus leads from the bulbus phaiyn- 

 geus to turn slightly to the left, between the large and yellowish salivary 

 glands. The first stomach is small, and its internal walls have deep 

 furrows in w^hicli are situated minute papillfe of irregular arrange- 

 ment; the opening of the hepatic duct is small and does not seem to be 

 muscularly controlled. The second stomach is considerably larger than 

 the first, and the furrows of the first stomach continue to line the walls of 

 the second. A short neck connects the second stomach to the thii-d 

 stomach ; this latter is large and pear shaped, with lamellated walls, and 

 leads by the narrower posterior end to the intestine, at two ram. from the 

 commencement of which is a widened ampulla, which Cuvier considered 

 to be an especial stomach. 



The liver is tri-lobed and dirty yellowish in colour, occupying a large 

 part of the visceral mass. The anterior lobe is concavo-convex in shape 

 and its surface is traversed by slight furi-ows ; the lower lobe is the 

 smallest of the three, and the ducts leading to the hepatic duct p,re, as this
