in addition to the above, the late Mr. .Tames Smith has obtained, at Stanwell, a 
small Spirifera, possessing a lengthened hinge-line, flattened wings, an angular dorsal 
fold, and sharp ribs visible near the front margin. Such characters would indicate 
it to bo a young form of S. vespertilio.

Ohs. The most satisfactory example of this species yet obtained in Queensland 
has been figured by Mr. R. Etheridge, E.R.S., who remarked on it — "We may refer 
this fragment to Sp. convolata, its extreme width and straight hinge-line essentially ally 
it to this shell ; the acute angles at the extremities are lost, still many of our Yorkshire 
shells strongly resemble this species ; the ribs on the mesial fold are also less defined 
than on most typical forms.”

Ohs. It is with considerable hesitation that I introduce this as a Queensland 
species. I have not yet seen a specimen either from this Colony or from New South 
” ales possessing smooth alar expansions in connection with as large a number of ribs 
described by McCoy. On the other hand, here are several in which the wings are 
^^ertainly devoid of costie, and the bodies of the shells bearing nine instead of from 
Sixteen to eighteen. The cardinal margin is long with acute angles, and the lateral 
portions of the valves spreading and wing-like. The fold is very prominent, high 
ov\ ards the front, and appears to h.ave been divided by a narrow groove. The sinus 
brrows the veutral umbone quite from its apex, gradually spreading out towards the 
font, where it is wide and moderately deep. Particularly well-marked growth-laminai 
Crossed the valves longitudinally. 
The wings are not devoid of ribs to the same extent as McCoy’s representation of 
• lata, but still sufficiently so to become a point of importance in the determination of 
6 species. The plain fold and sinus at once separate these shells from Spirifera 
‘^^epertilio, whilst the simple cost® are equally important in distinguishing them from 
eonvoluta.
