The specific characters of this species have already been given in 
Part T. of the present Catalogue (p. 190). De Koninck describes 
the Australian form as “ very large, straight, conical, elongated, 
covered with very fine longitudinal ribs, partly interrupted and cut 
transversely by striae of growth, a little oblique, and sometimes 
slightly undulating. Septa concave, subhemispherical, with straight 
sutures ; siphuncle central, rounded, slightly infundibuliform, and 
having a diameter about a tenth of that of the septa. The distance 
of the septa varies a little with the progressive development of the 
shell . . . The body-chamher is very long and spacious . . 
Bemarlcs. The species differs from Actinoceras striatum, J. Sow., 
sp., in the possession of very distinct and regular transverse lines 
of growth, and therefore the identity of the Australian with the 
English species must be left in doubt. Perhaps the former may be 
a variety of the latter. The^specimens are casts in a brown mica- 
ceous sandstone.
