222 PUPILLA, AUSTRALIA. 



types received from him, the lower one strong and elongate, 

 externally marked by a furrow, the upper one small, tuber- 

 cular. The last whorl has behind the lip a swelling followed 

 by a contraction, both individually variable in degree of de- 

 velopment. 



Length 3.4, diam. 1.6 mm.; 6 whorls. 



Length 3, diam. 1.5 mm, ; 5~y 2 whorls.

' ' Shell dextral, fissured, cylindrical, thin ; transparent, pale 

 brown; whorls 5y 2 , roundly convex, last small, obliquely and 

 transversely faintly striated; apex roundly obtuse; aperture 

 small, ovate-denticulated within with 4 prominent white teeth, 

 one placed on the body- whorl, elongated and rounded ; a 

 second on the columella, large and acute; two placed inside 

 the outer lip, the lower one long and prominent, the upper 

 moderate and rounded ; peristome whitish, thickened and ex- 

 panded ; margins continuous, with a thin coating of the callus 

 over the perforation. Length %, breadth y 2 lines" (Brazier}.

It does not appear likely that a shell so small as this is a 

 Pupilla. It may prove to be a Costigo (Vol. XXV, p. 366), if 

 that somewhat nebulous group be retained. Hedley writes : 

 "In the Australian Museum is one specimen labelled in Bra- 

 zier's hand 'Pupa scotti, Braz. Fitzroy Isd. N. E. A.' As he 

 particularly stated that but one was found (and no others 

 have since been obtained), this is clearly his type. I am 

 much puzzled to find that this type disagrees with the figure, 

 P. Z. S., 1874, pi. 83, figs. 24, 25, 26. Brazier, who is now 74, 

 has no recollection of the matter, except that the type was 

 unique. I enclose a camera lucida sketch drawn by myself of 

 this type of scotti. My opinion is that it is an immature 

 specimen and that it represents a Pupilla distinct from other 

 Australian species. Possibly Brazier, recognizing its imma- 

 turity, instructed the artist to 'develop' the labial armature."
