ilarg-aret River. 
Specimens from Cape Freycinet agree so closely in their features with 
the figure and flcseription of sagi that they can be so named, while solidus 
PiLsbry aiii)ears to be merely a large local variation of this species. 
The typical shell i.s small, with an attenuate spire with the whorls flat- 
tened, rather solid, with the und)ilicus always left a little open. The colora- 
tion is whitish with a few pale real streaks at times. There is no civciimbilical 
patch in this series, other wi.se there is no disen'pancy at all. A rather 
notable feature is the thickening of the columella and the strong white glaze 
connecting the inner and outer li])s, the latter having th(' edgi' stouter than 
usual. 
The tyi)e of solidus, here figured, is much larger and more solid, and be- 
longs to a series from the Margaret River, having the same conical attenuate 
spire with flattened whorls, and the longitudinal sculpture a little stronger.

Pilsbry wrote: “Fig. 30 is a small specimen from Cape Xaturalist. 
There are 5 whorls, the last inflated below, almost imperforate. It i.s beauti- 
fully streaked with opa(|ue, glossy white on a cortu'ous and inirplish brown 
ground. Alt. 20, diam. 11, longe.st axis of aperture 10, 7 mill. The aperture 
is decidedly more obliipu' than in the tyjiical foi-m from King (leorge Sound. 
It is not unlikely that this will prove a geographic race or variety. From the 
Cox collection.” Kobelt gave this the varietal name mil urulisto.rum. The series 
from which Pilsbry selected the figured .sb.ell is before me, and I am refiguring 
his specimen. Again it is immature, but numbers collected by Tom Carter 
at the same locality show that it develoiis into an elongate shell very like 
that from Margaret Ri\er, which 1 regard as sagi, but it is thin and has the 
mouth more e.xpanded, is smooth, and measures 25 mm. in length by 13 mm. 
in breadth. 
Local naturalists must study these shells and fix the status of the named 
forms.

IVhile collecting numerously B. jacksoiii at Deep River and Bow River, 
Mr. Sydney IV. -Jackson also found alive under debris on ground in dense 
hazel scrub at the Bow Rix'er some .shells of the kinijii series, but sculptured 
after the style of hrazieri and leemvifiensis. The narrow shell here selected 
as type measures 23 mm. in length by 11 mm. in breadth; a broader phell 
measures 23.5 mm. in length by 12.5 mm. in breadth. The sjiire about equals 
the aperture in length, and is not attenuate. The columella is appressed so 
that barely a chink remains, and there is a red eireumbilical jiatch, while the
