FOEAMINIFERA OF THE ATLANTIC OCEAN. 141 



from the Bay of Palermo/^ but this has a different shape and an 

 exserted neck and does not appear to be the same species. 



The name Frondicularia spathulata was first used by Williamson 

 for a species of a very different form from the British Coast which 

 does not appear to have been since recorded. Brady used the same 

 name for a species of a different form occurring in the Indo-Pacific 

 which I have named F. hradyi Cushman. The specific name spathu- 

 lata beii^ preoccupied in this genus, I have given the above name 

 to the species of the Mediterranean and the coast of western Europe.

Frondicularia pygmaea Sidebottom, Mem. Proc. Manchester Lit. Philos. 

 Soc, vol. 51, no. 9, 1907, p. 5, pi. 1, fig. 27. — Hekon-Aixen and Eab- 

 LAND, Proc. Roy. Irish Acad., vol. 31, pt. 64, 1913, p. 96, pi. 8, fig. 14. 



Description. — " The initial chamber appears to be nearly globular, 

 and the following ones are compressed, narrow and reflexed. The 

 septa are arched, and slightly sunk, and the orifice is simple. A 

 small wing commencing on the last chamber but one runs on either 

 side of the test, gradually broadening out and terminating as a 

 spine. The initial chamber is likewise armed with a small spine. 

 Two specimens were found and both consist of five chambers." 



Length of Delos figured specimen 0.20 mm.; off Clare Island 

 specimen about 0.15 mm. 



Distribution. — Sidebottom originally described this species from 

 the coast of the Island of Delos in the Mediterranean. Heron- Allen 

 and Earland record it from the Clare Island region, off Ireland, 

 and Earland had it from off Noss Head, Moray Firth. 



The microspheric form has a straight test without sign of coiling 

 as does the megalospheric. It seems to belong rather to Lingulina 

 than to Frondicularia.

Description.— T^st compressed, irregularly elliptical, initial end 

 usually narrow, bluntly pointed, proloculum subspherical, following 

 chambers coiled in part or not at all, quickly giving place to typical 

 V-shaped frondicularian chambers, highest in the center, thence 

 gradually tapering to the pointed lower ends; test occasionally with 

 a slight peripheral keel, sutures slightly depressed ; aperture circular
