down, binding the sand together without any decided filaments. Trama compact. Spores globose, inch
across, strongly echinulate.—TMs agrees with Hijdnanghm iu the trama separating in the centre, in consequence
of its compact structure, and with Octaviania iu its sterile base. There is only a single specimen, much
ì from etXioç, an intestine, and
eaten by insects.

Receptaculum sursum divisura in lacinias æquales intégras 1. emarginataa, apicibus liberis.
This genus is distinguished from Clathrus by the free apices of the laciniæ, and from Aseroë by their not being
deeply bifid. (Name from Xvu>, to loosen, aud oupo, a tail; from the free divisions.)

H a b . On the grouud, Archer.
Outer peridium split halfway down into about seven acuminate laciniæ, so as to form a deep sac, in which the
inner perfectly sessile peridium is sunk ; orifice plicate, but less so than in G. siriatus, not rising from a distinct
orbicular disc.—This differs from the small fonn of G. striatus in the perfectly sessile inner peridium, the less
regularly plicate orifice, and the saccate outer peridium. It is a small species, scarcely exceeding an inch m
diameter when dry. It differs from G. saccatus in the nature of the orifice.—P la t e CLXXXIII. Fig. 9 bis,
