Type-specimen of Lindley & Hutton in tie Manchester Museum^ 

 •Owens College (No. 321). 



Frond pinnate ; rachis slender, giving off at unequal intervals 

 linear lanceolate segments ; the segments are characterized by their 

 gradually tapered acuminate apices and constricted bases ; they are 

 traversed by several parallel veins. 



The type-specimen was obtained by "Williamson from Haibum 

 "Wyke, and presented with a drawing and brief description to 

 Lindley; it is described by the former as "no doubt produced by 

 some one of the Cycadeoideous stems of the Oolitic rocks." The 

 rachis is 13 cm. in length, bearing irregularly disposed linear 

 pinnae, about 7 mm. broad, attached by a narrow base. The longest 

 pinna measures 7 cm. in length, and tapers gradually to an 

 acuminate apex, but becomes suddenly nan-ow towards the basal 

 end ; a few of the pinnae appear to be laterally attached to the 

 rachis, with a slightly decurrent lower margin, but in one or two of
