stretches of the interior of the island; one was a siuall species of Helix, the 
other belonged to the genns Bullmun of M. de J.amarck.’’ Ferussac gave as 
the collector of liis 8hark Bay shells, ‘‘Gaudicho’’ ; this refers to C. Gaiidi- 
chaud, the apothecary on the lAanie, which visited Shark Bay in 1818. 
In further contirination, Botiez and Michaud are cited, as they figured 
the Shark Bay shell under the name Rulimus contulatus Ferussac, and acknow- 
ledged the as.sistance of Feinssac. 
The shell i.s roundly oval, the spire short, obtuse, less in length than the 
aperture, which is oval, outer lip thin, rather solid. The coloration of all the 
dead shells seen is white, but tlu" living shell is orange, longitudinally flamed 
with dull streaks. 
Aiie.x flattened not distinguished finnilv from adult whorls, the sculpture 
be ginning as faint wrinkled lines, the succeeding whorls sculptured with tine 
concentric lines cutting; the faint growth lines into small lozenges which 
vanish helow the periphery of the last whorl. Colunuhla short, rellocted tri- 
angularly over the umbilicus, which however is not dosed.

Smith wrote: “otislou'i .... Five other examples are considerably 
.smaller, averaging only 15 to 18 mm. in length. They are a trifle less 
globose, and more strongly granular just below the suture.’’ Pilsbry com- 
mented: “Apparently adult specimens of this small form before me are even 
smaller than the dimensions given by M. Smith, two measuring: Alt. 13.5 
diam. 9, longest axis of aperture 8 mill, whoils D/gl «ihI alt. 14.5, diain. 8.2, 
longest axis of aperture 8 mill., whorls a trifle over 5. They are strongly 
granose below the suture, and striped longitudinally with pale reddish or 
grey and opaque white.'’ Kobelt later also named this form, and it seems 
common and easily .se])arahle and not a dwarf of '^onslowi.” Collecting 
might solve the problem as there is no similar instanee of dwarfing in this 
family. 
Bothriembryon whitleyi sp. nov. 
Plate IT., fig. 21. 
A nice series, collected by my colleague, Mr. G. P. Whitley, at Gerald- 
ton, is composed of white dead shells. They are, however, quite fresh and 
do not appear to have been coloured. Shell small, dead wliifc ralher shin- 
ing subglohose ])erforate, perforation hidden by reflected columella. Apex 
of two whorls, finely ])unctato, a subvarix seiiarating these from the adult 
four whorls which are longitudinally radially wrinkled, the racUals crossed 
by concentric line.s, wliieh produce a subnodulose a])pearanee, the base of the 
last whorl smooth. The mouth is oval, the outer lip thin, the columella rather 
broadly reflected, hiding the umbilicus, but leaving it quite oi)en. Height 
16 mm., breadth 12.5 mm. This is a plumper shell than minor, and differs 
in coloration.
