554 Dr. F. A. Bather — Tube-building Fossil Anne/ides. 



straight round the tuhe. Whether each whorl was composed of 

 several tiles or only of one, continuous all round, is uncertain. The 

 length of a tile was about 6-5 mm., and of this the distal 3 mm. 

 overlapped the next whorl. 



The substance of the tiles does not seem to differ in any definite 

 way from that of either the surrounding matrix or the infilling of the 

 tube. Their surface, however, has occasionally a striated ' beefy ' 

 appearance. 



It is clear that this fossil accords with the interpretation that 

 Dr. 0. Beis has given of the Flysch fossils mentioned above. So far 

 as one can follow the descriptions in the absence of material, it seems 

 to approach most nearly the forms classed by Bothpletz (1897) under 

 Keclcia. " Hierunter verstehen wir die stielformigen und dichotom 

 verzweigten Fucoiden, welche in Folge von Quereinschniirungen wie 

 aus einer Beihe von Ringen zusammengesetzt erscheinen. Je nach 

 Erhaltungszustand erscheinen diese Bingwiilste auch schuppen- oder 

 scheideformig. Das Genus ist von [E. F.] Glocker 1840 [i.e. 1844] 

 (Acta Acad. Leop. Carol., xix [Suppl., Bd. ii, p. 319]) fur eine Art 

 aus dem Karpathensandstein Mahrens . . . aufgestellt worden, die er 

 als \_Keclcia~] annulata bezeichnete." The chief difficulty lies in the 

 words ' dichotom verzweigten '. Glocker's elaborately coloured 

 plate iv does in fact represent a much-branched structure. Of course, 

 our specimen might be a single branch of a branching tube, but 

 I greatly doubt it. However, for the sake of having a name, it may 

 be left in Keclcia for the present. 



Granularia (?) sp. (PL XXI Y, Fig. 2.) 

 A small piece of Gault clay [B.M. 39453], from Folkestone, Kent, 

 7 cm. by 5-7 cm. in area, is strewn with several fragments of tubes 

 composed of granules or pellets. This was bought from Edward 

 Charlesworth about 1860, and was entered in the register of the; 

 Geological Department as " ' oviform bodies', qy. worm castings ". Of 

 late years it has been placed on exhibition under the generic name 

 " Sabella(?)". On the other hand, there can be no doubt that the 

 specimen agrees in general character with several usually regarded 

 as ' fucoids ' and placed under some such name as Granularia. These 

 facts show that the palaeontologists of the British Museum were more 

 than prepared to accept the conclusions so lucidly drawn by Dr. Beis 

 (1910). 



The tubes are much like those from the Upper Cretaceous Alberese, 

 figured by Beis (pi. xvii, fig. 1) under the name Gramdaria lumbri- 

 coirfes, Heer; stouter and coarser than those figured by Bothpletz 

 (1897, pi. xxii, figs. 8, 9) under the same name; and most precisely 

 represented by the drawings of Phymatoderma ccelatum, Saporta (1873, 

 Paleont. Frang., Plantes Jurassiques, tome i, p. 472, pi. lxviii, 

 figs. 3, 2>a). 



The direction of the tubes is approximately parallel to the shorter 

 axis of the Gault slab. They are in rather short fragments, the longest 

 being about 22 mm., with an impression showing that it once reached 

 a length of fully 36 mm. The diameter is about 2 5 mm. Over the 

 whole specimen there is no evidence whatever that any of the tubes
