1. Papuina lintschuana Kobelt, forma infraplanata n. f. 

 Kobclt. Mart. Chemn. Conch. Cab. Ed. II, Vol. I, Heliceen, p. 700, PL 200, fig. 5, G. 



Hollandia, April 1911. 



This specimen agrees in nearly every respect with the description 

 and figures of Kobelt, but the aperture is not oviform but more straight 

 in shape, the part of upper peristome near the body-whorl is not reflected, 

 and above all, the base of shell is nearly flat, only slightly more convex 

 behind the aperture ; as Kobelt has but seen one specimen, it is not to 

 be made out, if this character is of much value or that intermediate 

 specimens will fill up these differences. I thus prefer to distinguish it as 

 forma infraplanata, instead of describing a new variety. 



2. Papuina taumantias Tapparone Canefri. 

 Tapp. Canefri. Fauna Mai. N. Guinea, p. 141, PI. 3, fig. 13, 14. 



Hussin, July 1910. 



The specimen is not typical; by its elevated spire and rosy peristome 

 it might belong to var. (3 of Tapp. Canefri (1. c), its diameter is nearly 

 31 mill., that of the type 33 mill.; as the author mentions no measurements 

 for the var., I do not know if this slight difference is of any importance. 

 The shell is rather worn and has but one narrow dark band at the peri- 

 phery. It is a somewhat doubtful specimen. 



3. Papuina brazierae Brazier. 



Brazier. Proc. Linn. Soc. N. S. Wales, Vol. I, 1876, p. 107. Pilsbrv. Man. of 

 Conch. Vol. VII, p. 43, PL 5, fig. 93-96. 



Mouth of the Sermorvai-river, March 3, 1911; Seko, Aug. 8, 1911. 



Both specimens are large, that from the first-named locality has only 

 weak wrinkles, the other one has no brown stain on the columella nor 

 on the body-whorl in the aperture, but both agree sufficiently with typical 

 specimens in other respects. 



4. Papuina lacteolota Smith. 



Smith. Ann. Mag. Nat. Hist. 1887, p. 420, PL 15, fig. 9. Pilsbrv. Man. of 

 Conch. Vol. VII, p. 25, PL 1, fig. 11. 



Kaiserin Augusta-river, Sept. 18, 1910, on a tree. 



This specimen is smaller, (diam. maj. 30 mill.) than the type (diam. 

 maj. 36 mill.), the aperture is smaller, more rounded, the columella less 

 expanded; as however the shell has been broken on the dorsal part of
