Two typical tests, one of which has three chambers. This 

 species occurs also at Marseilles, and Heron-Allen and Earland 

 report it at Noss Head in the Moray Firth.

Fig. 14a is somewhat similar to the " Challenger" illustration 

 of Lingulina carinata, pl. Ixv, fig. 16, but the sutures of the earlier 

 portion of the test are arched. The initial chamber is inflated, and 

 the four following chambers are well flattened. 



Fig. 15 has a continuous depression running down the centre 

 of the test similar to the " Palermo " example in the above reference. 

 Bruckmann (1904, Foram. der litanisch-kurischen Jura, pl. i, 

 figs. 18, 19) figures specimens with depressions under the name 

 F. spatidata Terquem, but the curving of the sutures is not the 

 same as in the example I figure. Besides the above there are 

 nine other tests, varying in minor details from fig. 14. Most of 

 these are more compressed. 



Frondicularia pacifica, sp. n. (Pl. IV, figs. 16, 17.) 



Test compressed, chambers arched, sutures sunk. Initial 

 chamber circular and inflated. Immediately above the initial 

 chamber a depression commences, which is continued throughout 

 the length of the test. The orifice is slightly produced and stellate. 

 The edges of the test are rounded and lobulate. The chambers, as 

 they are added, increase rather rapidly in width. The nearest 

 published figure to this form appears to be F. woodwardi Howchin, 

 1895, Carb. Foram. Western Australia, p. 197, pl. x, fig. 4 (Eept.
