[Note. — Besides the fossils enumerated in the foregoing Table, there are not a few others, which, consisting of internal casts only, it is impossible either to identify or describe. Some of these, there is every reason to suppose, represent new species, and one or two possibly new genera ; and such I reserve for future examination and comparison. — S. S.]
Notes on a New Species of Starfish from the Ironstone Beds of the Inferior Oolite of Northampton. By Dr. Thomas Wright, F.R.S.E. and G.S.
The genus Goniaster was proposed by Prof. Agassiz, in his ' Prodrome,' to include Starfishes with a large pentagonal body, having the margin bordered by a series of wide, thick plates or tesserae, superimposed in pairs, and which support spines, granules, &c. The upper and under surface of the disk is covered with small polygonal plates, set closely together like a mosaic, and fitted into this marginal framework : the free surface of the ossicles is smooth or covered with granulations. The ambulacral furrows are narrow, with two rows of pedal suckers therein ; the vent opens near the dorsal surface, and the mouth-opening is slit-like and pentagonal.
Muller and Troschel, in their ' System der Asteriden,' suppressed the genus Goniaster, and instead thereof erected the genera Astrogonium, Goniodiscus, and Stellaster. The diagnostic characters of these groups were chiefly obtained from the structure of the mar-
- I am indebted to Mr. Henry Woodward, F.G.S. &c., of the British Museum,
for this suggestion, offered as conjecture only.
