reflected almost covering up the umbilicus, the outer lip thin, and a glaze 
connects the inner lip to the outer lip across the body whorl. The apex is 
eroded but shows the coarse pitting of the mclo series. iMeasurements — ■ 
length 21 mm., breadth 15 mm. (Esperance ilallee Belt). The range of this 
form inland would be interesting, as we might get intermediate localities 
between this and the Centralian sycnceri. From Newman Kocks shells are 
a litth' more globose, spire shorter, and the colours reversed, being pale bi'own 
with a peripheral white band recalling cdi^taneus, but differing in sculidure.

A large series of shells collected alive by Mr. L. Glauert at Serpentine 
Palls, Darling Range, all agree in form an<l coloration though varying a little 
ill proportions. Thus some are shorter recalling the coastal hiiUd, and others 
are elongate similar to iyiduhts, but very unlike in shell texture. These are 
thin and are pale brownish-yellow thickly longitudinally streaked, being thus 
referable to the htilla style rather than to the indutus series. The ape.v is 
finely punctate the succeeding rvhoiTs rounded, the spire about equal to the 
mouth, four adult- whorls succeeding the two punctate whorls sharply. The 
columella is reflected, brownish purple, halving a very small umbilical fissure, 
the outer lip thin, the aiierture brown within. Scnlptui'e, rough closely set 
irregular radials overrun by concentric lines, almost forming a distinct can- 
cellation on the earlier whorls. A couple jiicked at random gi\-e measure- 
ments — length 25 mm., breadth It) mm., and length 32 mm., breadth Ifl nun. 
The shell figured (tjqie) measures 28 mm. in length and 16 mm. in breadth. 
The locality falls into the 30-iuch annual I'ainfall belt. 
Bothriembryon praecelsus sp. nov. 
Plate II., fig. 11. 
One specimen from Kellerberrin may be immature, but it is large and 
verj' distinct from any shell from the Darling Ranges or the Perth district. 
The locality is inward of the ranges, and lies in the lfl-15 inches rainfall 
belt. 
The shell is inflated but the sjjii'e is conical and shoif, the apertui'e a 
little longer than the spire and ojien, shell very thin. Coloration almost uni- 
form being brown, growth lines lighter. The apex is worn but shows a flat- 
tened two whorls stoi)ping suddinfly so that almost a varix appears: llnu’o 
is a reticrdato pitting now seen. The adult sculpture, consists of fine radials 
crossed by fine concentric lines almost cutting the radials into lozenges, these 
vanishing below the should(*r on the last whorl, only Ihe rather rude radials 
persisting. The columella is white, reflected, almost concealing the umbilicus, 
a very slight glaze crossing to the edge of the outer lip which is thin. The 
measurements read — length 29 mm., breadth 20 mm., length of aperture .17 
mm., breadth of npertirre 10 mm.
