NOTES AND ADDENDA. 



1. Lignite from (he Tries 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 silichied wood found at Quaco, and referred to in Acadian 

 Geology, p. 108. It is also of the same type with Dadoxylon Edvardianum, 

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

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

 of Virginia. 



2. Lower Carboniferous Fishes of New Bninsiviclc. 



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 seq. The bed affording 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 P. 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 the smallest of the whole, appears to be new, 

 and I shall begin by describing it. 



Palcconiscus (Rhadinichthys) modulus, S.N. — Length, live 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 line waving 

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

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

 preserved, but apparently small and nearer to pectorals than to anal. 

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

 heterocercal, with the lower lobe sharply pointed. Fins with well- 

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