band' 960 feet below the 'Ell-coal' at Goodliock Hill, Sbotts, 

 Lanarkshire. For this form Mr. Salter proposed the genus Antlira- 

 folcBmon (a name which, as he observes, ' has only a general signi- 

 fication, and is not intended to indicate a real relation to Palcemon,^ 

 to which genus it has not the least resemblance or affinity). He also 

 added the specific name of Grossartii. 



" Mr. Salter also proposed for the Coalbrook-dale form [Apus 

 dubiiis of Milne-Edwards) the sub-generic appellation of Palceo- 

 carabus. This sub-genus was subsequently erected into a genus by 

 the same author, and a new species, described under the specific 

 appellation Russellianus, was added." 



In a paper communicated to the Glasgow Geological Society,'^ from 

 which the above is an extract, Mr. Woodward has pointed out that 

 the characters upon which Mr. Salter depended for his new genus and 

 species were based on an accidental displacement of the antennules 

 and antennee. 



Mr. Woodward further concludes that there are no good grounds 

 for maintaining two genera on these Crustacean remains from the 

 Ironstone. The carapaces of A. Grossartii and F. Bussellianus 

 agreeing in all particulars. As Anth-apalcemon has two years' priority 

 over Falceocarahus, Mr. Woodward suggests the retention of the 

 older name. 



In their Paleeontology of Illinois (1868, vol. iii. p. 554) Messrs, 

 Meek and Worthen have figured and described another example of 

 this type under the name of AnthrapalcBmon gracilis, which in many 

 respects closely agrees with the Scottish and English forms. 



The subjoined note by Principal Dawson, E.E.S., on a new form of 

 Anthrapalcenion from Nova Scotia, adds yet another locality to the 

 wide distribution of this Palaeozoic type. — Edit. Geol. Mag.

The specimen referred to in the following 

 note is I believe the first example of a Ma- 

 crourous Crustacean from the Carboniferous 

 of Nova Scotia; and it is interesting to find, 

 as pointed out to me by Mr. Woodward, that 

 its affinities are so close with the long known 

 Palaocarabus dubius of Prestwich; and Antlira- 

 palcemon of Salter, from the English 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 

 the bands of black bituminous limestone which Fia. 1. 



occur in the middle part of the Coal Formation.
