CoTTON—CATALOGUE OF CONE SHELLS 231 
baveasli¢hthly different anchoring action, Hor comparison microphotographs of the 
denticles of Darioconus onania, Virgiconus linidus, Parviconus rutilus, Flaraconus 
anemone are reprodneed. Mr. IL. Beoek of the Adelaide (niversity kindly assisted 
me with the preparation of these photographs and also suggested the similarity 
of the anemone denticle to a whale harpoon. From this description it seems that 
the radula of Ploraconus anemone is probably as venomous as any, though no fa- 
talities have been vreeorded from Southern Austvalia, The animal usually with- 
draws rapidly into the shell when handled, which may account for the nmmunity en- 
joyed hy many collectors who have handled them. Furthermore, it is doubtful 
whether a small cone of two or three inches in length has sufficient poison for a 
fatal dose, thongh it may be quite sufficient to paralyse smaller marine creatimes. 
Known records of fatal bites have been from larger species of about four to six 
inches in shell height for the average specimen, such as Rollus geographus and 
Darieconus tertile, Asa wise precaution collectors will be well advised to pick up 
live specimens by the spire end of the shell, keeping the hand well away frora the 
narrow or anterior end from whieh the proboscis projects. 
Species actually recorded as having inflicted bites are aulicus, textile, tulipa, 
marmoreus, (eagraphus, 
CLASSIFICATION, 
A preliminary attempt has been made to allot species to suitable genera, 
though it is realized that more genera will be required before a satisfactory classi- 
fication ean be offered, Genotypes are figured from specimens with definite locali- 
ties. Principal synonyms and varietal names are listed under the respective spe- 
cies, but in this survey the species names are used in the wider sense and in some 
cases may represent groups of geographical subspecies. Tomlin, 1937, give a full 
list of specific names up to that date. Many more specimens remain in this eol- 
lection lo be examined and identified and may add considerably to this eatalogus. 
The genus Conella Swainson (1840) genotype Conus plicato Swainson is now 
placed under the family Columbellidae, 
The genera are here arranged in groups which may even represent subfamilies.
