TEXTILARIA AGGLUTINANS. 147 



3. Textjlarta subflabelliformis, Hantken, 1875. Plate V, fig. 21. 



Textilaeia subflabellifoemis, Hantken, 1875(1881). Mitth. Jahrb. Ung. Geol. 



Anstalt, vol. iv, p. 66, 

 pi. xv, fig. 2. 



This form is closely allied to T. sagittula, but shorter and broader. Von 

 Hantken' s illustration (fig. 2) is a good counterpart of our fig. 21. Fornasini 

 figures the nearly allied T. unita, 'Boll. Soc. Geol. Ital.,' vol. vi, 1887, p. 397, 

 pi. s, figs. 2, 2(7, 2 6, differing from our specimen in being larger, thicker, and 

 narrower, and therefore less broadly triangular. Both of these have the style of 

 growth of T. sagittula as to the setting-on of the chambers, which are nearly 

 horizontal and compact; but extending laterally they give a greater breadth to 

 the shell. This form is short in growth, and whether it be young or dwarf is 

 doubtful. 



Textilaria flabelliformis, Giimbel, 1868, ' Abhandl. Akad. Bayer.,' vol. x, p. 6-17, 

 pi. ii, figs. 83 a, b, having limbate sutures, is analogous, in this respect, to the 

 var. jugosa of T. sagittula. It is otherwise similar to von Hantken's fig. 2, except 

 that its chambers are curved. Fornasini, in the ' Boll. Soc. Geol. Ital.,' vol. vi, 

 1887, p. 400, pi. xi, figs. 2, 2 a, has illustrated a " short form of T. sagittula,'" 

 which has the upper edges of the chambers thickened so as to form a limbation, 

 as in var. jugosa. Except for this feature it would be sub flabelliformis. 



Occurrence. — The specimen of Textilaria subflabelliformis, PI. V, fig. 21, is in 

 the Searles-Wood Collection in the British Museum, and was probably obtained 

 from Sutton. We have not noted its occurrence in other exposures of the 

 Coralline Crag.
