RECORDS OF W.A. MUSEUM. 
Palaeontological Contributions to the Geology of Western Australia, 
1910). Some of the notes then made were recently discovered 
among other papers, and I decided to investigate matters more 
thoroughly as I now had the necessary leisure. 
It was found that, whereas the locality mentioned in the 
description of Saltevella hardmani was correct, the record on the 
label attached to the Olenellus had been inaccurately copied. In a 
list of Western Australian Fossils in the Collection of the British 
Museum (Nat. Hist.) obtained for my assistance by the Acting 
Government Geologist, Mr. H. P. Woodward, F.G.S., in 1908, the 
locality for the Trilobite is given as “ River south of Base Line 
Camp ” and “Ord River”- — that is to say, the Trilobite remains were 
collected in two localities, a fact confirmed by the following 
paragraph in Mr. Etheridge’s description. 1 “ On the weathered 
surface of a similar limestone rock, and from the same locality as 
the head just described, there is a short spine probably belonging 
to the present species ; if so, it would be the telson. In another 
piece of limestone, similar to those containing the head and telson, 
there is a portion of a thoracic segment which agrees in form with 
the first two segments of an Olenellus ; this may also belong to the 
present species.” 
The addition of the single word “ Camp ” simplifies the localisa- 
tion of the Cambrian beds from which the fossils were obtained. 
As the specimens collected in 1883 and 1884 and deposited in 
the Geological Museum at Fremantle are tabulated in the form of 
an appendix to Hardman’s 1884 Report, published in 1885, a search 
was made, with the result that an entry, “Hb27. Limestone with 
lead, zinc, and fossils, from river south of Base Line Camp ; 
several specimens, 2 ” was discovered. 
No “ Base Line Camp” is referred to in the Report for 1883, 
but in that for the succeeding year, paragraphs 295 s to 299 describe 
“ Section between J 34 and the Base Line Camp," and in paragraph 
298 we read “ Base Line Camp, Z 27,” which an examination of 
Hardman’s map shows was placed on the left (north) side of the
