126 POMPECKJ. JURASSIC FAUNA OF CAPE FLORA, [norw. POL. EXP. 



Beani Trautsch. is, moreover, otherwise interpreted from Lahusen and 

 Eichwaldi2. 



Leaving the last, unauthenticated occurrence, out of consideration, Lin- 

 gula Beani Phill. is principally distributed in various, especially lower, zones 

 of Bajocian. 



Discina reffexa Sow. sp. has a similar distribution^. It perhaps occurs 

 already in the Lias of England; it is especially frequent in the Blea Wyke 

 Beds, and is perhaps also found in the "Dogger" of Yorkshire. Quen- 

 stedt mentions it from the Opahnus Clay of Boll in Wiirttemberg, and 

 Lepsius has found it in strata of the same age at Gundershofen in Alsace*. 

 Trautschold's statement that Discina reflexa occurs in his middle stratum of 

 the Jura of Moscow, is as doubtful as is the same author's statement about 

 the Lingula Beani Phill. 



As we have seen, Discina reflexa Sow. sp., as also Lingula Beani 

 Phill. is principally confined to the Bajocian. 



The two species, Lingula Beani Phill. and Discina reflexa Sow. sp., 

 have hitherto never been found together, except in the Blea WyJce Beds 

 of YorJcshire, i. e. in, the very lowest zones of the Bajocian (vis. in the 

 AaUnien May.-Eym. Haug. e. p.). 



The Belemnite remains from the sandy hard marl and the light gray 

 marl of Elmwood, are too imperfect to allow of any accurate specific deter- 

 mination. Only this much can be stated with certainty, that they agree 

 neither with the species from the Callovian of Cape Flora, nor with species 

 from the Callovian on the whole, of arctic regions, Russia and other parts. 



If the best preserved (and most frequently occurring) remains of Belem- 

 nites, which were compared with Belemnites Beyrichi 0pp. in the description 

 of the fauna, are really closely allied to this species, this would indicate the

2 Fiehelkorn (Zeitschr. d. Deutsch. Geol, Ges. 1893, p. 445) unites Lingula ovalis Sow. 

 Beani Phill. and Zeta Quenst. erroneously, however, and thus gives to Lingula 

 Beani the same wide distribution as Trautschold.
