Principal Dawson — On New Palceozoic Crustacea. 
band ’ 960 feet below tlie ‘ Ell-coal ’ at Goodhock Hill, Shotts, 
Lanarkshire. For tbis form Mr. Salter proposed the genus Anthra- 
palcemon (a name wkich, as he observes, ‘ has only a general signi- 
fication, and is not intended to indicate a real relation to Palcemon,’ 
to wkick genus it bas not tbe least resemblance or affinity). He also 
added tbe specific name of Grossartii. 
“ Mr. Salter also proposed for tbe Coalbrook-dale form (Apus 
diibius of Milne-Edwards) tbe sub-generic appellation of Palceo- 
carabus. Tbis sub-genus was subsequently erected into a genus by 
tbe same author, and a new species, described under tbe specific 
appellation Russellianus , was added.” 
In a paper communicated to tbe Glasgow Geological Society, 1 from 
wbicb the above is an extract, Mr. Woodward has pointed out tbat 
tbe characters upon wbicb Mr. Salter depended for bis new genus and 
species were based on an accidental displacement of the antennules 
and antennae. 
Mr. Woodward further concludes tliat tbere are no good grounds 
for maintaining two genera on tbese Crustacean remains from tbe 
Ironstone. The carapaces of A. Grossartii and P. Russellianus 
agreeing in all particulars. As Anthrapalcemon has two years’ priority 
over Pa/ceocarabus, Mr. Wood ward suggests the retention of tbe 
older name. 
In tbeir Palfeontology of Illinois (1868, vol. iii. p. 554) Messrs. 
Meek and Worthen bave figured and described another example of 
tbis type under the name of Anthrapalcemon gracilis, wbicb in many 
respects closely agrees witli the Scottish and Englisb forms. 
Tbe subjoined note by Principal Dawson, F.R.S., on a new form of 
Anthrapalcemon from Nova Scotia, adds yet another locality to tbe 
wide distribution of tbis Palaeozoic type. — Edit. Geol. Mag.

Fig. 1.* Anthrapalcemon ( Palceocarabus ) Hilliana, n.s. 
The specimen referred to in the following 
note is I believe tbe first example of a Ma- 
crourous Crustacean from tbe Carboniferous 
of Nova Scotia ; and it is interesting to find, 
as pointed out to me by Mr. Woodward, tbat 
its affinities are so close with tbe long known 
Palceocarabus dubius of Prestwicb, and Anthra- 
palcemon of Salter, from tbe Englisb and Scottish 
Coal-measures. It was found by Mr. Albert 
G. Hill, manager of the Cumberland Coal-mine, 
at the South Joggins in Nova Scotia, in one of 
tbe bands of black bituminous limestone wbicb Fig. 1. 
occur in the middle part of tbe Coal Formation.
