[Norr.—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. 8. ] 
Notes on a New Spxcres of Srarrisu from the Ironstone Buns of 
the Invertor Oourre of Northampton. By Dr. Toomas Wricut, 
F.R.S.E. and G.S. 
Tre genus G'oniaster was proposed by Prof Agassiz, in his ¢ Pro~ 
drome,’ to include Starfishes with a large pentagonal body, having 
the margin bordered by a series of oe thick plates or tesserex, 
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 ambuiacral furrows are narrow, with two 
- rows of pedal suckers therein ; the vent opens near the dorsal sur- 
face, and the mouth-opening is slit-like and pentagonal. 
Miller and Troschel, in their ‘System der Asteriden,’ suppressed 
the genus Goniaster, and instead thereof erected the genera Astro- 
gonium, Goniodiscus, and Stellaster. The diagnostic characters of 
these groups were chiefly obtained from the structure of the mar- 
* Tam indebted to Mr. Henry Woodward, F.G.8. &c., of the British Museum, 
for this suggestion, offered as conjecture only.
