Original description Test oval, compressed; periphery rounded; ecto-entosolenian; external neck short, flattened transversely, and armed on each side with a strong, recurved spine; aperture, a transverse fissure. Length .2 mm. This species bears a superficial resemblance to the form figured by Rymer Jones ( 1872, Trans. Linn. Soc. Lond. vol. xxx, pp. 51, 67, fig. 13) as L. vulgaris typica Will. with circlet of recurved spines (three in the figured specimen). His form, however, as may be gathered from the text, has a test circular in section, and a round aperture, while the species now described belongs to the second of the subdivisions of Lagena, given in the "Challenger" Report, the test being compressed and the aperture fissurine. Shore mud, and at 10, and 14 fathoms. Very rare.

A single specimen from Station 23. This differs from Chaster's figure in the shape of the chamber, which is short, sub-globular, and compressed, as compared with Chaster's compressed oval figure. The neck, as in Chaster's specimen, is a broad, flat extension of the shell, with two strongly recurved hooks, and the neck is of the full width of the body of the shell, both in Chaster's specimen and in our own. Similar specimens of the same short type have been found in "Goldseeker" dredgings off Noss Head, Moray Firth (70 metres), and at other stations round the Scottish coast. For comparison we also figure the normal type of L. falcata from one of the "Goldseeker" dredgings in Orkney.

Two specimens at Stn. 4, one representing Chaster’s original elongate type and the other the short broad form as figured by us (ut supra). Previously only recorded ut supra and by Wright from post-Tertiary deposits at Altcar (Proc. Liverpool Geol. Soc. vol. ix. 1904, p. 364).
