In external appearance, our shell equally resembles the genus Aemnlona, C. A. 
White,* but here again a want of knowledge of its internal characters, and the apparent 
absence of a punctate test, preclude any definite reference. 
The only Australian fossil having any resemblance to S,. ? lilymerensis is Atrypa 
plicatelU, De Koninek,t from the so-called Lower Devonian of New South Wales, 
which has a similar sculpture, but is very much less deltoid and attenuated towards the 
umboncs.

Obs. Two crushed examples, not to be distinguished from this widely distributed 
shell, were obtained by the late Mr. James Smith, with the characteristic spines 
exposed as a frill around the margin of the valves, each separate from its neighbour, a 
character which at once separates A. Boysii from the allied A. planosulcata. The shell 
figured by Prof. De Koninek J under the latter name does not, as portrayed, exhibit, to 
tty mind, the slightest resemblance to the species in question. The difficulty of 
correct identification is further increased by the careless manner in which the references 
in the text are made to the figures on the plates, a fault which more or less pervades 
the whole work. Through this, it is at times difficult to understand to which figure the 
Irofessor is referring in his descriptions.

Obs. A crushed, but at the same time readily recognisable specimen of this 
^finally characteristic shell has been found by Mr. W. H. Eands. Although only a east 
e sulcus of the ventral valve is still traceable, and there are indistinct remains of 
oncentric ornamental lines of growth.
