reddish tone, but always the coloration is characteristic. The apex is punc- 
tate, the thiinbling tiiier tlian in the southern meio : the longitudinal irregular 
ribbing is cut into nodules by the concentric lining and there is commonly 
a notable deep line just below the suture which is never seen in tnelo, the 
sculpture being much more ])ronounced in this species. Some specimens 
elongate Avith age and thus we get Keeve’.s ‘'rhodostoma” and Pilsbry’s 
conispira. The normal shell measures 2.5 mm. in length by 1G.5 mm. in 
breadth, conispira being 25 by 14.5 mm., and others up to 28 mm. by 10.5 
mm. 
Bothriemhryon bradshawi sp. nov. 
Plate II., tig. 14. 
A good series, collected by Mr. F. K. Bradshaw at Tambellup, north ol 
the Stirling Ranges, and sontli of Broome Hill, provides an interesting 
problem. 
The shell is small, thin, sjjire and mouth about equal in length, spire 
conical, mouth a little iullated so that it ajjpears someAvhat intermediate 
between the Idngii ami melo series. 
The apex is a little more elevated than in the mdo form, but not so 
elate as in the kinijii group, and is finely punctate, the sciilptiu'e fading 
away so that no vaiix-like division is seen. The adult seuljdiu'e consists of 
fine sloping radials being more rude as the shell develops, and contiiming on 
to the base of the last whorl. On the first adult whorl a tew widely spaced 
(‘onceiitric lines arc* seen which soon vanish. The early coloration is whitish 
mottled with reddish brown, the motllings massing so that the coloration of 
the last Avhorl resembles that of some of the well-colored forms of kingii.

Bothriemhryon irvineanus sp. nov. 
Plate 11., fig. 15. 
A series, collected by Mrs. Irvine, a very well-known IVest Australian 
shell lover, at Cape Naturaliste, along with B. naturalistanim, but probably 
occupying a distinct station ecologically, is here named. 
The shell is thin, elongale, ot the mdo form, but nari'ower and showing 
no perforation, recalling serpent in us, hut broader, the spire a little shorter 
than the aperture, columella twisted. Coloration uniform with no red 
circumbilical patch. The n()ex is coarsely punctate r('calling that of kingii^ 
but broader, more elevated than that of bulla; adult whorl strongly rudely 
railially ribbed crossed by concentric ditches iiroducing a strong snbnodulose 
effect, the radials persisting strongly on to the body whorl but concentiic 
ditches disappear on base. Length of type, 2G nun. ; breadth, 16 mm. 
Bothriemhryon richeanus sp. nov. 
Plate II., fig'. 16. 
A series labelled “Cape Riche, King George’s Sound, S.IV. Australia’^ 
by Brazier, proves that the locality “King George’s Sound’’ was used for the 
whole of that south-west l)lock, as Cape Riche is sixty miles distant, and is 
a well known landmark. 
The shells are quite distinct, being strongly grannlose recalling 
Iceuwinensis and hrazlerp but are iiarroAver than the former, and broader 
than the latter. They belong to the kingii series, hut are broader with the
