spire not attenuate and about the length of the aperture. The apical whorls 
are .strongly punctate, the adult ivliorls rounded, the sculpture being rather 
strongly nodulose, the nodules irregular, but squarish, and persisting but 
weakening on to the base of the body whorl. The shell is thin and conse- 
quently the outer lii> is thin, the columella reflected, leaving so minute a chink 
that the shell appears imperforate. The coloration is a dirty fawn with 
indistinct longitudinal streakings of dull red; the red cireumbilical patch is 
only seen in one specimen. The type measures 24 mm. in length, 13 mm. in 
breadth, the aperture 12 mm.

Smith’s comparison reads: “B. me'o is a broader and more bulky species, 
and B. kinaii is more acumitialc above, less granular, and exhibits more 
coloration both e.xternally and within Ihe aperture. The umbilicus is more 
closed than in the present species, and is surrounded by a brown zone.” The 
notable feature is the strong granulation and this aiipears to connect it with 
the kingii serie.s. Mr. A. W. B. Powell, of the Auckland Museum, has given 
mo three specimems collected at F'linder’s Bay by Chnneut L. Wragge, and 
these are to]iotype.s of the species. The apical features jirove it to be refer- 
able to the kinfiH series fi'om which at sight it appears very different. The 
shell is elongate, rather stout, the spire about equal to the np(>rtnre, but not 
attenuate, the whorls apiireciably shouldered. The apex is elevated, finely 
punctate, the |)unctalions separable until th(' end of two whorls, where a 
definite small varix can be seen. The adult scul])ture consists of coarse granu- 
lation, rough separate radials being cut into oblong lozenges by concentric 
deep irregular lines, the unevenness of the' radials givitig a nodulose sugges- 
tion. This continues on to the upper half of the last whorl, the rough radials 
alone being observed on the lower half. The columella is white, reflected, but 
leaving a notable umbilical chink behind; a white glaze connects the inner 
lip with the outer lip which is thin. The coloration is a uniform creamy 
white. 
The length of the figured shell is 29 mm., the breadth 15 mm. A specimen 
from Lake Cave, Margaret River, generally agrees but is much narrower, 
measuring 28 mm. by 13 mm. 
Another series from Margaret River is short and bi'oad, recalling the 
melo series, but the apex seems to Ix'long to (he kinijii series. The mouth and 
aperture are about equal, and the sculpture is similar to that of the above, 
but much weaker, the concentric lines disajipearing on the body whorl. The 
columella is reflected but hnves an open chink, and the outer lip is thin. The 
coloration is dirty whitt' with flesh stia'aks. There aiiiiears to b(! much con- 
fusion in the ai'ea from Cape Leeuwin to Cape Naturaliste, and for the 
present this form is being only named subspeeifically Bothriembryon 
leeuwinensis eventus subsp, nov. ; the type measuring 23 mm. in length by 
14 mm. in breadth.
