REPORTS ON GRAPTOLITES. 
By T. S. Hall , 4 /.A. (Melbourne University). 
From 2 Miles E. of Myrtleford. Collected by Mr. E. J. Dunn. 
No. 1459. 
The specimen is a fragment of one of the Dicellograptidse, and is. 
indicative of Upper Ordovician age. 
From Kerrie, Riddell. Collected by Mr. A. E. Kitson. Nos. 
1460, 1461. 
The specimens are counterparts, and show an example of a species of 
Climacograptus. The age is either Upper Ordovician or Lower Silurian. 
7.6.07. 
From 8 Chains W. of S.-E. corner of Allot. 15B of h, Parish of 
Barp, near Dunolly. Collected by Mr. W. H. Ferguson. 
Nos. 1462-1484. 
Specimens Nos. 1470, 1473, 1478, 1479, 1481, are apparently 
Dictyonema, with a very line mesh, No. 1481 being almost certainly so. 
Nos. 1477 and 1483 seem to be Dendrograptus. Nos. 1462, 1472, 1480, 
1482, and 1484 seem to be crustaceans allied to Rhinopterocaris , while 
No. 1466 is perhaps a Brachiopod. 
The whole of the specimens are very badly preserved, so that identi¬ 
fications of the graptolites are not possible. The age of the rocks is 
uncertain, but is probably Lower Ordovician. 
From the N.-E. corner of Dr. Wolfenden’s Paddock, Tarnagulla- 
road, Parish of Painswick [No. 18 of IX.]. Collected by 
Mr. W. H. Ferguson. Nos. 1539-1617. 
The following are present: — 
Clonograptus sp. Nos. 1566, 1569, 1575, 1591, 1595 (?), 1596, 
1614. 
C. magnipLCiis (?). No. 1579. 
C. flexilis. Nos. 1592, 1600, 1601, 1617 (?). 
Bryograptus sp. No. 1580 (?). 
Tetragraptus decipiens. Nos. 1569, 1591(7), 1606, 1608 (?), 
1615, 1616 (?). 
Dichograptus octobrachiatus. No. 1613 (?)—A 5-armed form. 
Dictyonema spp. No. 1555, 1609 (?). 
Phyllograptus typus (?), 1558. 
Sponge spicules are common; the following genera seem repre¬ 
sented :—- 
Stephanella. Nos. 1541(7), 1591(7). 
Protospongia. No. 1601 ■(?). 
Some of the others contain sponge spicules and graptolite fragments, 
but many are quite indeterminate. Nos. 1545-1554 inclusive are missing. 
I have very little hesitation in referring the beds to the Lancefieldian 
series. The abundance of sponge remains is remarkable, and most of 
them consist of straight spicules with a radiating arrangement. Specimens 
Nos. 1605 and 1616, which are counterparts, are striking, but, like the 
whole collection, graptolites and sponges alike are extremely indistinct 
through weathering.
