T. Davidson — On Tertiary Brachiopoda. 153 



list of Brachiopoda from the Tertiary formations of Austria, and of 

 which a monograph is expected from the able pen of Prof. Suess : — 



Three new species of Terebratula, one of Terebratulina^ Megeilea truncata {oblita, 

 Michelotti) : Platidia Anomioides, Scacchi sp., Argiope decoUata, Cheran., A. Neapo- 

 Utana, Scacchi, A. squamosa, Eichwald, and a new species. Also a new species of 

 Crania and of Lingnla. , 



Very few Tertiary Brachiopoda are recorded from Eussia. 

 Belgian Species.

fig. 4. 1843. 



Large examples of this fine Ling%da have been found in the 



Assise Scaldisien, sables gaunes (crag), at Stenyvenberg, near 



Antwerp. It is, however, very rarely obtained entire. The best 



examples hitherto collected are preserved in the Museum of Brussels.

This interesting species has been very minutely described and 



illustrated by M. Bosquet. It occurs in a deposit attributed to the 



Middle Oligocene at Elsloo, a locality situated at the distance of 



about a hundred steps from the Belgian frontier. It cannot, strictly 



speaking, be considered a Belgian species, as no example has been 



hitherto picked up on Belgian soil ; but as its locality is so near to 



the Belgian frontier, we have deemed it desirable to record its 



presence.

 d'une description Geologique de la Belgique, p. 407. 1868. 

 • (Not Pileopsis variabilis of Galeotti. — T.D.) 

 " Shell irregular, insequivalve, transversely oval, slightly conical, 

 patelliform, depressed : vertex almost central : surface exteriorly un- 

 equal and rugose. Interior of upper valve (the only one known) 

 concave, margin narrow, granulated. Four muscular impressions : 

 the posterior ones are more or less circular, lying close to the inner 

 edge of the granulated margin, and separated from each other by a 

 flat space not equal in size to one of the muscular impressions ; 

 the anterior pair are irregularly oval, diverging from near the centre 

 towards the posterior lateral margin : a slight prominence existing 

 before the central pair. Vascular impressions not well defined, 

 structure punctuated."^ Length 7, width 9 lines. 



In 1852 Sir C. Lyell placed in my hands for description and illus- 

 tration the unattached valve of a Crania he had obtained from the 

 Eocene beds of Dieghem, near Brussels. On comparing this valve 

 with others of the C. HoeningJiausi of Michelotti and which occur
