120 PAPUINA. 



Dr. Kobelt, ten years ago, referred them to the Partutidce (Bericht 

 ueber die Wissensch. Leistungen in der Malak., 1890, p. 374). Mr. 

 C. F. Ancey later writes as follows concerning them : " I succeeded 

 when in Paris in December, 1896, in procuring specimens. My 

 opinion was they were not at all " Bulimi," as suggested by Dr. 

 Hartman, but modified forms of the Diplomorpha type. I now think 

 there can be but little doubt they belong to the latter genus. The 

 texture of shell, outline and external characters are not dissimilar, 

 and in the best preserved specimens of Diplomorpha ruga and ber- 

 nieri both have the throat tinged with blood-red color as in the typi- 

 cal D. layardi, although the describer mentioned the fact in one of 

 them only. No epidermis remains on the shells, not very numerous 

 indeed, observed by me, but it may be very deciduous, and its absence 

 gives the shells a rough and uneven appearance. I am indebted to 

 Mr. Ph. Dautzenberg for a nice example of berm'eri, and the shell is 

 somewhat straw-colored like ruga. Of the latter, I procured two 

 specimens, one much larger than the type, the other, on the contrary, 

 considerably smaller. The parietal denticle is wanting in the species 

 under consideration, as well as in Diplomorpha delatouri" 



AUSTRALIAN BULIMOID HELICID^E. 



Various Australian species, originally described as Bulimus, have 

 proved to belong to groups of Helicidce already described in this 

 work. As the contour is suggestive of Bulimulidce, this seems an 

 appropriate place to supply the omitted descriptions. They are fig- 

 ured on plates 4 and 5.

" Shell nearly imperforate, of a lengthened oval form, rather thin, 

 smooth, very indistinctly striated, not shining, white, with numerous 

 black and reddish spiral bands, and, on each whorl, more or less 

 distinctly, a band of elongated black or reddish markings ; spire 

 acutely conical, bluish at the tip ; whorls 6, very slightly convex, 

 last not ventricose, deeply and irregularly stained with black and 

 red ; aperture uprightly oval ; peristome simple, regular, thin, colu- 

 mellar margin white, slightly expanded and reflected, but not quite 

 covering the umbilical orifice. Length 0.77, breadth 0.40, length of 

 aperture 0.40 inch" (Cox).
