NOEGGERATniOPSIS. 183 



Hislopi, which were first described by McCoy in 1847. McCoy 1 

 referred them to a Triassic species instituted by Morris as Zeugo- 

 pihyllites ehngatus, which has been transferred recently by Mr. Seward 2 

 to the genus Pheenicopsis of Heer. It was not until 1892 that 

 Mr. Etheridge, jun., pointed out that McCoy's determination was 

 incorrect. McCoy's specimens were redescribed 3 in 1902, when 

 I referred the leaves in question to JVbeggeratMopsis Goepperti, 

 a species described by Schmalhausen 4 from the Permian rocks of 

 Russia. A full account of the confusion with regard to McCoy's 

 plant will be found in that paper. At that time, as I stated, 

 I was unable to arrive at a definite conclusion with regard to the 

 identity of N~. Goepperti with N. Hislopi, despite their great 

 similarity in habit and detail. I am now, however, of opinion 

 that the Australia fronds should be referred to N. Hislopi, since 

 such differences as exist seem to be insufficient to warrant separation. 

 Zeiller has shown that Schmalhausen's species must now be trans- 

 ferred to Cordaites, and that Noeggerathiopsis is probably not identical 

 with that genus. 



It appears to me that all the three species instituted by Dana 5 

 in 1849 are identical with N. Hislopi. Feistmantel 6 has already 

 united two of the leaves in question. 



The plant recently figured by Shirley 7 as Noeggerathia (?), sp., 

 is of very uncertain affinity. The leaf doubtfully ascribed to the 

 genus Noeggeratlnopsis by Seward 8 is rather like some of the 

 Indian and Australian species described by Feistmantel. The same 

 author 9 has recently expressed doubt whether the Tonquin 

 specimens referred to this species by Zeiller may not be identical 

 with Pheenicopsis elongata (Morris).
