disposed spiral^, and the "habit o£ the twig support a reference to 

 BrachypliylUcm. Some American Cretaceous examples of J^racliy- 

 phyllum have been assigned on anatomical grounds by Jeffrey to 

 the Araucarinese, but it would be rash to assume this affinity for all 

 the numerous impressions included in the genus. 



Elatocladtjs pla]S"a (Feistmantel). (PL XTI, fig. 20.) 



The piece of foliage shoot shown in fig. 20 bears two-ranked 

 leaves spirally disposed, reaching a length of 3 cm., and barely 1 mm. 

 broad. There is a well-marked midrib, and the lamina tapers 

 gradually towards an acute apex ; the lower margin is decurrent. 

 Shoots of this type are figured by Feistmantel ^ from the Madras 

 coast as Taxites planus. In view of the impossibility of 

 determining the affinity of specimens such as these, we adopt the 

 non-committal generic name Elatocladus. 



PLANTA INCERT^ SEDIS. 



Desmiophtllum sp. (PL XII, figs. 18 <5^ & 18 6.) 



This fragment of a linear leaf, 8*5 mm. broad, has seven parallel 

 veins about 0*5 mm. apart. The impression is not sufficiently well 

 preserved to demonstrate the presence or absence of interstitial 

 ' veins.' It may be a piece of a Podozamites leaf, a leaf of 

 Phoenicopsis, or a fragment of a Cycadean leaflet. It agrees 

 ■closely with some of the specimens from Indian Jurassic beds 

 named by Feistmantel ^ Podozamites lanceolatiis, and it is also 

 very similar to a small specimen figured by Feistmantel from the 

 Madras coast ^ as a piece of a Cycadean leaflet. In view of the 

 impossibility of determining accurately the specimen, we employ 

 the convenient designation Desmiophylhim^ It is, however, 

 noteworthy that while Podozamites is known from Indian beds, 

 Phoenicopsis has not been recorded from the Gondwana Series. 



CONCLTJSIOl^. 



The following is a list of our determinations : — 



Cladojphlebis reversa (Feistmantel) 



\_=Todites Williamso7ii (Brongniart)]. 

 Cladopfdehis denticulata Brongniart. 

 Taeniopteris spatulata McClelland. 

 Araucarites cutchensis Feistmantel. 

 Brachyphylluin mainillare Brongniart. 

 Elatocladus plana (Feistmantel). 

 Desm.iophyllu')n sp. 



Five of these species we believe to be identical with plants 

 recorded by Feistmantel from the Madras coast, and in all
