Type-specimen. The type-specimen of Phillips is in the York 

 Museum. 



Frond linear or hroadly lanceolate ; the lamina may be almost 

 entire or divided into distally truncate segments varying considerably 

 in breadth ; the apex is obtuse, and the lamina is usually entire at 

 the distal end of the frond. The veins are more or less at right 

 angles to the rachis, and are either simple or dichotomously 

 branched; the branching may occur close to the rachis or in any 

 part of the lamina. 



Phillips' figure, which is somewhat crude, represents the type- 

 specimen half the natural size ; the veins are indistinct. Some 

 forms of Anomozamites Nilssoni exhibit a fairly close agreement 

 with the fronds of Nilssonia compta, but the segments of the 

 latter species are usually more oblique to the axis of the frond, and
