original description it is said, “ breadth more than double its length. Morris descnbes 
ve^pertilio as “transversely fusiform” ; but, in his illustrations, Morris himself has, 1 
helieve, figured two distinct species under Sowerby’s name. His fibres 1 and 2 y i. 
17),* are 8. vespertilio, whilst fig. 3 of the same plate is another form, much shorter, 
less triangular, and much too high a shell. Professor He Koninck, wholly ignormg 
Morris’s description, adopts the extraordinary method of applying the name to tli 
aberrant fig. 3. His S. vesperfiUo is, therefore, to some extent not the species 
by the earlier writers named, but is distinct, and agrees with the casts above described 
from Queensland. If the latter, and the figures cited in He Koninck’s work are in want 
of a name, I would propose to call them Spirifera Stntchlimi, after the late Mr. 
Samuel Stutchbury, the first Government Geologist of New South Males, and at a 
time when that Colony and Queensland formed one territory. The true 8 vesperitUo 
is a long-winged, very alate shell, and quite distinct from the short triangular deltoid 
forms noiv under consideration. , r j-

Obs. Wo possess a decorticated example, which, from its shape and genera 
appearance, seems to be this species. It is from the Bowen Eiver Senes. Biit hte 
De Koninck’s figure, more ribs are present than laid down in Morris s descnption. 
Probably ten, as stated by Morris, may bo regarded as the low'est number, graduating 
un to fifteen or twenty, by counting all the bifurcations. ^ ^ 
Another specimen possessing prominent angular ribs, united into indefinite bun es 
of three, may also be 8. tasmaniensis (PI. 10, fig. 15). It is possible that this species 
will prove to be only a variety of the much better marked 8pirifera StoJeesii. Ainongs 
extra- Australian species, compare 8. musebachanus, E. Eoemer,t from Texas, whic is 
very elosely allied, having the same shape, clustered ribs, and highly dccussatea
