of Halani or some otlier Cirripeds ; and on examining the collection at Jermyn Street,* 
analogous impressions were found, produced by the attachment of these shells ; so that, 
although no other traces of the shells have been found, the family may, I think, be 
added to the list.”

Obs. The first Insect discovered in Australian Mesozoic rocks has been described 
Under the above name b}^ Dr. Henry Woodward. It was found by my Colleague in 1881. 
The remains consist of the proximal half of the posterior wing of a Libelluloid [usect, 
and exhibit the nervurcs in a remarkably fine state of preservation. As preserved, the 
jiortion measured twenty-five mm. in length, and nearly ifteon mm. in depth, and when 
perfect was probably forty-five mm. in total length. Dr. Woodward remarks — “It is 
the posterior wing of a Nouropterous Insect of the sub-order Odonata, Pabr., and 
perhaps referable to the sub-family Gomphinai, one genus of which, Austrogomphiis, de 
Soly.s, having five species, is characteristic of Australia and Tasmania.” 
It is very closely allied to forms met with in the Lower Secondary rocks of 
England — viz., the Purbeck Beds of Dorsetshire.

fhe discovery of the above, Mr. J. H. Simmonds has found Insect remains in the Ipswich 
Coal Measures.

Obs. Prof. G. Busk, who examined the species, remarked that he had not 
before noticed it, and that it did not occur in a series (Tertiary) he had examined from 
fount Gambier. The genus has not hitherto been found lower than the Cretaceous 
eriod. It occurs not unfreq uontly on the exteriors of the Wollumbilla fossils.
