NOTES AND ADDENDA. 



1. Lijiiitefrom the Trkis of New Brunswick. 



Jackson and Alger, in their memoir on Nova Scotia Geology, mentioned 

 the occurrence of lignite at Cape Blomidon in the Triassic sandstones, 

 but I have not succeeded in discovering it. Last summer Mr Ells, of the 

 Geological Survey, obtained a specimen in the sandstones of the opposite 

 side of the Bay of Fundy at Martin's Head. This specimen proves to be 

 a coniferous wood with one row of large disks in the cells, and of the same 

 type with silicified wood found at Quaco, and referred to in Acadian 

 Geology, p. 108. It is also of the same type witli Dadoxyhm Edvardianmn, 

 referred to above as characteristic of the Trias of Prince Edward Island, 

 and is similar to fossil wood which I have received from tlie Mesozoic 

 of Virginia. 



2. Lower Carhoniferous Fislies of Nno Brunsivich. 



The recent sinking of a shaft on the property of the Beliveau Albertite 

 and Oil Company on the Petitcodiac River, has exposed a new and interest- 

 ing deposit of fossil fishes in the rich bituminous shales of that district, 

 which contain the remarkable deposits of Albertite, described in Acadian 

 Geology, p. 231 et scq. The bed affordhig these fossils is a dark-brown 

 bituminous shale, and, I am informed by Mr E. B. Chandler, to whom I am 

 indebted for an interesting collection of the fish remains, is from four to 

 five feet thick. The specimens thus presented, with those previously 

 in my collection and one kindly given to me by Mr F. Adams of this 

 University, and the valuable memoirs recently published by Dr Newberry 

 in the Ohio Report and by Dr Traquair in the Journal of the Geological 

 Society, enable me now to give a revision of the fishes of this locality, as 

 described by Dr Jackson in his Report of 1851 on the Albert mine, which 

 I was unable to do in my second edition, owing to the small number of 

 specimens at my disposal. 



In the collections in my possession I recognise, in all, five species — three 

 of them very small, and two of larger size. Of these, one, which is un- 

 usually well preserved, and is tlic smallest of the whole, appears to be new, 

 and I shall begin by describing it. 



Palceoniscus {RhadhiichtJiys) iimhdns, S.N. — Length, 'asG to six centi- 

 metres ; greatest breadth, 15 to 17 millimetres— the proportion of length 

 to breadth being about five to one and a half. Head, oval and obtuse ; 

 details not preserved, except that the bones are sculptured with fine waving 

 lines. Body gracefully curved, and upper lobe of tail long and slender. 

 Pectoral fins small, with stout, mijointed rays. Ventral not distinctly 

 preserved, l)ut apparently small and nearer to pectorals than to anal. 

 Dorsal and anal of moderate size and opposite each other. Caudal very 

 heterocercal, with tlie lower lobe sharply pointed. Fins witli well- 

 developed fulcral spines especially large at the base of the caudal. Scales
