Age—Silurian. 
From H T alkali a. Centennial Mine, Stringer 1 s Creek . 
Nos. 1176, it 77. Collected by Mr. J. P. L. Kenny. 
These are quite unidentifiable, and may not even be graptolites. 
From Kangerong (E. of Dromana ). • Bald Hill Quarry. 
Nos. 1164-1175. Collected by Mr. A. E. Kitson, F.G.S. 
Didymograptus sp., No. 1172.

Tetragraptus approximatus, Nicholson, Nos. 1166, 1167 (counter¬ 
parts). The specimen is larger than any I have seen, the branches being 
more than 2.5 cm. long. 
Dicliogr aptus sp., No. 1169. 
(?) Clonograptus magnificus, Pritchard, No. 1168.

Didymograptus sp., No. 1409. 
Tetragraptus quadribrachiatus, J. Hall, Nos. 1410, 141 1. 
Tetragraptus serra ( ?), Brongn. 
Nos. 1415, 1416, 1417 are mineral specimens.

Tetragraptus serra, Brongn., Nos. 1420, 1424. 
Tetragraptus quadribrachiatus , J. Hall, Nos. 1421, 1423. 
Clonograptus (?) flexilis, J. Hall, No. 1427. 
Indeterminate, No. 1426. 
If the determination of Clonograptus flexilis is correct, as I consider 
almost certain, then the beds show an approach to the Lancefield series, 
and are older than the typical Bendigo series as hitherto dealt with.

14 in 1 cm., inclined at 40 deg., of even width, overlapping about three- 
quarters of their length. Sicula broad ; virgula about 1.5 mm. long.
