Nos. 102 and 103 came from the bluff X.W. of the junction of Little 
Boy's Creek and the Thomson River. They are dark blue mudstones, 
showing the impression of a peculiar suboval fossil, which is slightly at¬ 
tenuated, pointed and curved at one end, and rounded at the other. The 
surface is deeply concentrically grooved, and the central area is occupied 
by a wrinkled and sub-elevated boss. This specimen apparently represents 
the remains of a depressed conical shell which has been flattened in the 
plane of bedding. It may possibly be allied to the tent-like shell Hercyn- 
ella, a genus not yet having described Australian species, but which I 
have recorded from the Yeringian beds of Victoria. 1 
From Quarter Sheet No. 34 S.W. (Wood's Point). Collected by 
Mr. O. A. L. Whitelaw, Nos. 104-117. 
From Barkly River. 
104. ? Fucoid remains and mud wrinkles. 
105. ? Trails of fucoids and ripple marks. 
106. ? Fucoid remains. 
Note. —These rocks are comparable with the Carboniferous series of the 
Broken and Delatite Rivers. 
From Macallister River. 
107. Ochreous and micaceous conglomerate with imperfect casts of 
fossils, including ? Orthoceras. 
- From lazarinVs Spur. 
108. no, in, 113. Quartzose and felspathic conglomerate, with hollow 
casts of fossils—? monticuliporids, very imperfectly preserved. 
109. 112. Micaceous sandstone or conglomerate, with obscure traces of 
fossils. 
From W. Watershed, Barkly River, above Crescent Creek. 
114, 115, 117. Arenaceous shales, with graphitic-like bands and patches 
— ? organic (fucoidal). 
116. A shalv and crumpled phyllite with nodular inclusions—? organic. 
This specimen probably came from older beds than the above. 
From Quarter Sheet 22, N.W. (Baw Baw), Collected by Mr. W. 
Baragwanath, jun. Nos. 118-128. 
118. Ferruginous gritty mudstone, with obscure traces of fossils (casts). 
119. (4 specimens.) Irregularly bedded felspathic sandstone of a 
bluish colour, with ochreous cavities, due to the impressions of fossils 
(brachiopods and ? polyzoa, indet.). 
From Waterloo Gully, 2 miles S. of Mt. Lookout. 
120. A dark-brown ferruginous sandstone, with remains of brachiopods 
and crinoids (indet). 
From Donnelly' 1 s Creek. 
121. Ferruginous fossiliferous conglomerate, with obscure remains of 
corals and ? polyzoa (indet.). 
122. Graphitic shale, with plant remains (indet.) 
123. Shalv fossiliferous sandstone, with indeterminate remains of 
brachiopods and crinoids. 
124. Fossiliferous sandstone, with inclusions of indurated shalv 
fragments. The fossils are obscure, and chieflv consist of small ramose 
corals or polyzoa.
