Excerpt from book: III.?On a Collection of Graptolites from Mandurama; by T. S. Hall, M.A., Biological School, Melbourne University. [Plate VI.] I to thank Mr. E. F. Pittman, A.K.S.M., Government Geologist, for kindly- giving me the opportunity of examining a collection of graptolites from Mandurama. Mr. Pittman says: " They come from Mandurama, associated with rocks containing radiolaria, and in the same beds I found eome specimens of trilobites?apparently a new species of Agnostus." The number of specimens is small, though several species are represented. Two only seem well enough preserved for recognition, and they appear to be new, though closely allied to well known forms. The new species are Climacograptug a/finis and Diplograptus manduramte, while an undesignated Diplograptus is also figured. There appear to be other species both of Climacograpius and of Diplograptus present, but the specimens are very- indistinct. Climacogbapttjs Affines, n. sp. (PL VI, Fig. 1.) Hydrosome parallel sided, attaining its full width about three millimetres from the sicula, rounding rather rapidly to a point at the sicular end. Thecse twelve inches ten millimetres, opening at right angles to the long axis of the polypary. In compressed specimens the mouth indents the edge of the polypary for a little more than a third of its width. Inner edge of thec? not visible. Virgula free for about five millimetres. Virgella traceable for about three millimetres. No trace of lateral spines on the earlier thecse. The species is closely allied to C. normalii, Lapw., the only noticeable difference being the length of the virgella, a comparison having been made with specimens from Hartfell which were identified by the late Professor H. A. Nicholson. DlPMOBAPTUS lIANDUBAMju, ?. p. (PI. VI, Fig. 2.) ...
