1915] HOLDEN—CUTICLES OF CONIFERS 225 
2. On account of the character of its cuticle, the so-called 
Palissya indica of FEISTMANTEL cannot properly be referred to that 
or any other fossil genus; and to point out its resemblance to the 
living Retinospora, it is suggested that it be called Retinosporitis 
indica. 
3. Echinostrobus expansus closely resembles many living mem- 
bers of the Cupressineae, both in epidermis and in phyllotaxy; 
accordingly it would seem better to retain the old name of LINDLEY 
and Hutton, Thuyitis expansus. 
4. Taxitis tenerrimus has a type of cuticle common to many 
~ extant conifers, and its affinities cannot be decided. 
5. The epidermal structure of Podozamites lanceolatus consti- 
tutes another reason for referring that genus to the conifers rather 
than to the cycads. 
In conclusion, I wish to thank Professor SEWARD for this oppor- 
tunity to study the fossil conifers sent by the Director of the 
Indian Geological Survey, and to compare them with the living 
ones in the collections at the Botany School, and for valuable 
suggestions in regard to this work.
