HELIX-HADEA. 167 



Brazier says : " I have seen only one specimen of this species, and 

 it differs from H. incei and If. yulei by being more depressed and 

 broader, and in its lesser markings." 



H. INCEI Pfeiffer. PL 39, figs. 77, 78, 79, 80, 81. 



Shell partly covered umbilicate, depressed-globose, light buff with 

 spiral stripes of chestnut, one wider baud just under the suture, 

 another slightly narrower a short distance above the periphery, with 

 a variable number of lines upon the base and upper surface. Per- 

 istome white, with a brown spot at the root of the columella. 



Compact, solid, the umbilicus narrow and overhung by the trian- 

 gularly expanded basal lip ; spire low; whorls 62, slightly convex, 

 the last descending in front, rather swollen around the umbilicus, 

 which is obliquely excavated behind the baso-columellar lip. Aper- 

 ture nearly white inside, and showing the bands ; lip white, ex- 

 panded, dilated over the umbilicus, and having a purplish-brown 

 spot at its root and spreading a little upon the base, coloring it 

 around the axis. 



Alt. 25, greater diam. 32 mill, (large, thinner form). 



Alt. 22-0-, greater diam. 30 mill, (average specimen). 



Alt. 17, greater diam. 23* mill, (small form). 



Queensland in forest country, generally distributed.

An abundant species, usually smaller than If. appendiculata or 

 lessoni, light buff with brown bands and lines and a white lip over- 

 hanging the umbilicus. Although the columella has a dark spot at 

 its root, there is no distinct brown circum-umbilical patch as in the 

 closely allied H. yulei, a species further differing in its constantly 

 brown lip. The variation in size is shown in my illustrations. The 

 base around the umbilicus is clear yellowish, not suffused with brown 

 or closely banded, as it is in H. appendiculata and H. lessoni. 



H. PR^TERMISSI Cox. PI. 43. fig. 40. 



Shell deeply, openly, and rather narrowly umbilicated, globose, 

 solid, closely and finely striated, glossy, uniformly of a pale brownish 

 yellow color, obscurely banded with fine pale chestnut lines ; spire 

 obtusely conical ; whorls 7, rather convex, the last inflated and de-
