* 
From spur between Boys and B>ell Creeks, on track along Thomson River , 
4 1 miles below the Jordan junction. 
(Nos. 488-521 and 539-546. Collected by Mr. Wm. Baragwanath, jun.) 
With the exception of Nos. 504, 540 and 541, which are indeterminate, 
all the slabs show specimens of Monograptus, but in no case are they suffi¬ 
ciently well preserved for determination. Only very rarely can the 
characters' of the thecae be even indistinctly recognised. The virgula is, 
however, almost always visible as a shallow semi-cylindrical groove, and 
serrations can be seen on the side opposite to this. There is a general 
agreement in shape in practically all the specimens. They are stout and 
have a scarcely perceptible sigmoidal curvature on the virgular side. Nos. 
490, 496,, 539, and 546 appear to belong to the sub-genus Pristiograptus .
