SELLARDS: NEW GENUS OF FERNS. 187 



of the pinnule, connate with the pinnule below, or the outer 

 part of the lobe overlapping slightly. In the pinnules ap- 

 proaching the base of the frond the lobes are progressively less 

 strongly developed, entirely disappearing on the reduced basal 

 pinnules. Main rachis of the frond brokenly and roughly striate 

 throughout its entire length. Midvein of the pinnule moderately 

 strong, continuing to near the apex, straight or nearly so, join- 

 ing the rachis with a short downward curve. Lateral veins 

 indistinct ; those of the auricles best preserved. These leave 

 the rachis w^th a slight curve, run straight and apparently 

 simple to the border. In the first auricle (top of fig. 1, plate 

 XLII, left side) six veins can be counted in the distance of 3 

 mm. On some of the pinnules of the eroded specimen (plate 

 XLI) the lateral veins show indistinctly. They leave the mid- 

 vein obliquely and curve in, passing to the borders; w^hether 

 simple or forked, cannot be made out. 



Two specimens of this species are found in the collection, 

 both of wdiich are photographed. The smaller one is well pre- 

 served and covered by a thick coaly layer, entirely obscuring 

 the venation except in the lobes of the auricles. This speci- 

 men show^s well the distinct lobe between the pinnules. The 

 second specimen is of an eroded frond, somewhat defaced. The 

 lobate base, however, is well showm on some of the pinnules. 

 The species has a very different appearance from others of the 

 genus, due to the odd shape of the pinnules and their lobate 

 bases. The large specimen, plate XLI, has evidently the nat- 

 ural sh'ape of the frond, except that the apices of the pinnules 

 are broken and somewhat displaced. The frond is rigid, 

 strongly curved at the base, and again less strongly curved in 

 the opposite direction at the apex. The extreme apex is not 

 preserved. 



The first specimen of this species, that of plate XLI, was col- 

 lected by Mr. Sterling.
