EXTRA-BRITISH ASTEROIDEA. 109 



ASTEKIAS SCHTJLZII, Gotta. 



This is described and figured in Roemer, 1841, 'Die Verstein. Norddeutsch. 

 Kreidegeb.,' p. 28, pi. vi, fig. 21, as follows : " Fi'mfeckig mit fiinf kurzen Strahlen, 

 unten vertieft und in der Mitte mit fiinf Erhabenheiten ; der vorstehende Rand 

 gewolbt und zwischen je zwei Strahlenspitzen mit etwa 45 schmalen Tafelchen 

 besetzt." 



The description reads as if the specimen belonged to the genus Staurander aster, 

 but neither this nor the figure given is much aid in the exact identification of the 

 species. 



A cast of a fossil Asteroid is ascribed to the same species under the name of 

 Stellaster Schulzii, by Geinitz, ' Palaeontographica,' vol. xx, pt. 2, pi. v, figs. 3, 4. 

 This cast, however, looks like a cast of a species of either Calliderma or 

 Nymphaster. 



ASTEEIAS? DUNKEHI, Roem&r, 1841. 'Die Verstein. norddeutsch. Kreidegeb.,' 



p. 27. 



This species is described as follows : " Die Flachentafelchen sind langer als 

 breit, 46 eckig, schriigrandig f ein gekornt und nahe am obern Rande durchbohrt.'' 

 Only isolated plates were known. I am unable to identify the species with other 

 known Asteroids. The illustration given is not very clear. 



According to Roemer, these isolated plates were described by Dunker and 

 Koch, 1837, ' Norddeutsch. Oolithgeb.,' as plates of Cidaris varialtilis. 



CCELASTER COULONI, Ayassiz, 1836. 'Mem. Soc. Sci. Nat. Neuchatel,' vol. i, p. 191. 



No figure was given of this species by Agassiz. A fossil Asteroid figured by 

 Fritel, ' Le Naturalists,' vol. xvi, 1902, p. 79, as this species, appears to be some- 

 what like Nymphaster marginatus. 



CUPULASTER PAUPER, Fric, 1893. ' Arch. Landesdf. Bohmen,' ix, no. 1, p. 112. 



This species is named from a specimen 3 mm. in diameter, which so obviously 

 presents the large terminal plates which are common to all very young forms 

 of starfish, that it is useless to speculate as to its identity. 



Locality and Strati graphical Position. -- Cretaceous (Priesener Schichten), 

 Waldek, near Bensen, Bohemia.
