62 OTOZAMITES. 



with 0. Klipsteinii in having auriculate pinnae, hroader and stouter 

 than the majority of species of the genus. In describing the type 

 specimen, Lindley and Hutton ask if the plant may be a pinnated 

 leaf of the Cycadeoidece, but reply with a decided negative; in the 

 second volume of the Fossil Flora the generic name Otopteris is 

 substituted by the authors of the species for Cyclopteris, under 

 which the plant was originally described. In the Leckenby Collec- 

 tion in the Woodwardian Museum, Cambridge, there are several 

 very fine specimens of Otozamites Beanii, which in some instances 

 show a terminal portion with small pinnae very similar to such 

 an apical tip as is represented in PL I. Fig. 3. In the Yorkshire 

 plant the species are, however, very distinctly auriculate, and 

 have the upper portion of the base more prominently lobed than 

 is the case in 0. JTlipsteinn (Dunk.). In one of Leckenby's 

 specimens, which possesses a rachis 43*5 cm. long, the largest 

 pinna has a length of 3 cm. and a breadth of 1*9 cm., the smallest 

 measuring 1 cm. by 7 mm. Some of Zigno's figures of his species 

 Otozamites Molinianus l present a striking likeness to 0. Beanii, 

 and ought most likely to be referred to that species. Kurr's figure 

 of what he calls Zamites Handehlohi- agrees very closely with 

 the specimen represented in PI. IV. Fig. 4 ; the genus Otozamites 

 has been rightly substituted by Schimper for Kurr's species. 

 The larger pinnae of 0. Klipsteinii show a certain resemblance 

 to those of some few previously described plants ; but in no case 

 does the similarity appear sufficiently pronounced to justify a 

 reference to the same species. In the third volume of the 

 Oondwana Flora of India, 3 Feistmantel figures some isolated 

 pinnae under the name Glossozamites StoUcxkanus, Feist., and 

 describes them as probably constituting the largest representatives 

 of Schimper's genus. The form of these large segments is not 

 at all unlike that of the Wealden pinnae, but in the latter case 

 the auriculate base favours the adoption of the genus Otozamites. 

 The plant described many years ago by Goppert, from a much 

 lower geological horizon, under the name of Cyclopteris frondosa 4 

 (Gb'pp.), may be compared, as regards the form of its leaf segments,
