The type of CO. rubroguttata from the Hargraves collection is preserved 
in the Australian Museum. It seems to me to be the typical form of 
P. tincta. Perhaps a smaller more closely latticed form that occurs also 
on the Australian coast may be distinguished as var. corrugata. 
Hab. Queensland:—5 to 10 fathoms, Hope Island; Two Isles, off 
Cape Flattery; Lizard Island; Murray Island; Mapoon; Mornington

Hocycioroma Boettger. 
Hucyclotoma Boettger, Nachr. Malak. Gesell., xxvii., 1895, p. 55. Type 
Daphnella fusifornis. ; 
From Daphnella this genus is distinguished by a spirally striated 
nucleus. On the adult whorls the spiral sculpture developes into pro- 
minent keels. Its members are chiefly associated with a coral reef fauna. 
Besides the type the founder included in his genus Plewrotoma 
tricarinata Kiener and Clathurella bicarinata Pease. Addition of the 
following is now suggested :—Plewrotoma lactea Reeve, P. hindsii Reeve, 
P. inquinatu Reeve, P. carinulata Souverbie, Daphnella varicifera Pease, 
and D. trivaricosa yon Martens.
