170 RALPH TATE, 
S. curTa, sp. nov., Pl. x., fig. 1. 
This genus was founded by D’Orbigny in 1841, and its type- 
species, S. Bellardi, from the Older Miocene of Turin has remained 
till now unique, <A good figure of it is given in Fischer’s Manuel 
de Conchyliologie, but is more fully illustrated in Nicholson’s 
Manual of Palxontology. 
Nicholson placed the genus in Sepiade, Fischer in Belopteride, 
Tryon in Belemnitide ; this last location seems to me to be the 
best, as Spirulirostra may be viewed as a Belemnite with a sub- 
spiral phragmacone lying obliquely within the alveolar cavity. . 
An example of the present species was collected by me at Bird- 
rock Bluff, near Geelong, in January 1890, and I announced its 
discovery to the Royal Society of South Australia at its April 
meeting of that year; during the following summer I was suc- 
cessful in obtaining a second example at the same locality. 
The rostrum of the Australian species is more robust, is shortly- 
pointed, and is less arched dorsally and ventrally, where it is more: 
or less truncated. Lateral axis of rostrum 8, ventro-dorsal axis 12, 
length to apex of phragmacone 16 ; length of alveolar cavity above. 
plane of apex of phragmacone 29 (incomplete). 
Class GASTROPODA. 
Genus Murew. 
Subgenus DMuricidea. 
Of the described species of T'rophon, only 7’. icosiphyllus, makes. 
an approach to the characters of the genus, the rest belong as also. 
do some species of Ocinebra, e.g. O. biconicus, to Muricidea. 
Subgenus Muricopsis. 
Murex (Ocinebra) alveolatus and I. crassiliratus belong here. 
Genus Clavilithes. 
_ This genus, so characteristically Eocene, is represented in the: 
Kocene-beds of Australia by F. incompositus, F. bulbodes, and F. 
Tateanus, whose relations to the type-species of the genus, /usus- 
longaevus, Solander, I had already indicated.
