Characters. — Tapering and bent ; many oblique riblets on each chamber, 

 excepting sometimes the latest. 



Occurrence. — Dentalina ohliqtiestriata, as stated in the First Part of this 

 Monograph, appears not to have been found in a recent condition. No mention 

 of it is made by Brady in the ' Challenger ' Report. It has been recorded from 

 the Yorkshire Lias (Tate and Blake) ; from the London Clay (Sherborn and 

 Chapman) ; and we have it from the Casterlian of the Kattendyk Docks, Antwerp. 

 So far as the Crag is concerned, we have nothing to add to the record in the First 

 Part of the Monograph. 



3. Dentalina padperata, d'Orbigny, 1846. Plate I, figs. 13 — 18 and 20. 



Part I, 1866, pages 59 and 63 ; and Appendices I and II, Tables, No. 39.

 taken as a subtypical form to which certain Dentalines might be conveniently 

 referred. Their relationship one to another, and to D. communis, d'Orb., was 

 carefully indicated in the nomenclatorial lists at pages 58 — 62. Names upon 

 names have been given for this kind of smooth, arcuate, tapering, and very 



1 Signor C. Pornasini ('Boll. Soc. Geol. Ital.,' ix, 1890, pp. 345-6) points out that in the 

 synonyms " D. Geintziana, Terquem," should be changed to " D. matutina, Terquem ;" and " pi. ii " 

 should be inserted.
