ilarly the genus is absent from the Lower Cretaceous of 

 Portugal. Arber (1917) comments on absence of Otoza- 

 mites from Neocomian flora of New Zealand although he 

 records Ptilophyllum which is of doubtful generic distinct- 

 ness. Ptilophyllum has also been recorded from Patagonia 

 by Halle (1913, p. 34, pi. 3, f. 1-12) in association with 

 Marchantites, Nathorstia, Gleichenites, Cladophlebis, Ruf- 

 fordia, etc., from Upper Jurassic or Lower Cretaceous. 



Kuntz in 1901 recorded 4 species of Otozamites from the 

 Lias of Piedra Pintada, northern Patagonia : Wieland in 

 1916 describes 17 species of Otozamites from Lias of south- 

 ern Mexico: and Halle in 1913 recorded 4 forms from Gra- 

 ham Land.

Pinnate fronds of apparently large size, the longest frag- 

 ment collected measuring 27 cm. in length and 15 cm. in 

 width and showing no approach to either end. Simple pin- 

 nate. Coriaceous in texture. Stipe stout, about 6 mm. in 

 diameter in the laminar region. Pinnae alternate relatively 

 narrow and elongate, linear lanceolate, the tips narrowed 

 curved upward slightly, the wider ones roundly pointed, 

 attached to the upper margin of the stipe by about half their 

 width, the distal side of the base wider than the proximal 

 and slightly auriculate, the latter rounded. Veins thin and 

 close, immersed in the leaf substance, parallel except at the 

 base. The pinnae form angles of about 70 with the stipe, 

 they are slightly sigmoid curving outward and then upward, 

 the larger are 8 cm. in length by n mm. in maximum width, 

 the smaller are 6.5 cm. in length by 6 mm. in maximum
