Neuropteris antipoda. Nou. Sp. 



Frond pinnate (or bi-pinnate?) ; pinnae probably linear- 

 lanceolate ; pinnules coriaceous, slightly falcate, symmetrical, 

 regular (seven in the space of 40 millimetres), alternate, 

 slightly angled, ovate-lanceolate, closely set, subauriculate, 

 and only attached to rachis by a very short pedicel. Costa 

 fine and flexuous but distinct, continuous beyond middle of 

 pinnule ; secondary nerves arising from costa and reaching 

 margin at an acute angle, few, distant (about six pairs), 

 alternate, flexuous, dichotomous. 



Breadth of pinna, about 36 millimetres ; breadth of pin- 

 nula, 6 to 7 mil. ; length of pinnula, about 19 mil. 



This distinct form approaches N. gigantea Brongt., but the 

 small number of nerves is very exceptional, and is very 

 characteristic.

Alethopteris serratifolia. Nov. sp. 



Frond bipinnate ; pinna very oblique, sub-alternate, dis- 

 tant ; pinnuke rather coriaceous-lanceolate, falcate, and 

 somewhat obtuse, oblique, slightly incurved, closely set or 

 adnate, decurrent, dilated towards base where crispate, 

 margins often overlapping are strongly distantly dentate or 

 serrate ; midrib somewhat flexuous, rather thick, evanescing 

 towards apex ; veins oblique, rather distant, forking once or 

 twice before reaching margin. Stipes with two well-marked 

 grooves, giving an angled appearance ; rachis usually with one 

 central groove ; average distance apart of pinna?, 27 milli- 

 metres ; breadth of pinnae, about 28 millimetres,near to rachis ; 

 average length of medial pinnae, about 8 inches ; length of 

 larger pinnulae, 17 millimetres ; greatest breadth at base, 

 about 7 millimetres ; breadth of stipes, 31- to 4 millimetres ; 

 length of fragment, 10 inches. Occurring in shaly beds at 

 Lord's Hill, New Town. 



This form is very handsome, and is easily distinguished 

 from A. Anstralis by its more robust appearance and its 

 crisp or sinuous dentate pinnulae. In some respects it ap- 

 proaches A. currani (Ten. Woods), but its more robust form 

 the greater size of the pinnulss, and the more coarsely and 

 continuously dentate margins, easily distinguishes it from 

 that species. 



Genus Odontopteris. Brongt. 



Fronds pinnate ; generally bi-pinnate at the apex. Pinnae, 

 pinnate, and pinnatifid. The apical ones single, sub-oppo- 

 site, and sub-alternate, linear-lanceolate ; pinnules obliquely 

 inserted by the whole base ; decurrent free, but towards the
