KXTRA-BniTTSTT ASTEROmEA. 109 



AsTEItlAS Srnri.zii, Caffn. 



This is (lescril)e(l ami figured in Roemer, IS^-l, 'Die Verstein. Norddeiitsch. 

 Krcidegeb.,' p. 28, pi. vi, fig. 21,asfolloAys : " Fiinfeckig niit fi'inf kurzen Strahlen, 

 uiiteii voi'tieft und in der Mitte mit fi'inf Erliabcnlieiten ; dor vorstolicnde Rand 

 gewc'ilbt mid zwischen jo zwci Strahleuspitzen mit etwa l-j selimalcn Tiifelchen 

 besetzt." 



The description reads as if the .specimen belonged to the genus Staurauderaster, 

 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 

 Slellaster Schthii, In- Geinitz, ' Pala^ontographica,' vol. xx, pt. 2, pi. v, figs. 3, 4. 

 Tliis cast, however, looks like a cast of a species of either Callldenna or 

 Nymjihaster.

p. 27. 



This species is described as follows : " Die Fliichentiifelchen sind liinger als 

 breit, 4—6 eckig, schriigrandigfein gekornt und nahe am obcrn Rande durchl)ohrt.'' 

 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 Dunkcr and 

 Koch, 1837, ' Norddeut.sch. Oolithgeb.,' as plates of Ciihiris rarialiilin.

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

 Fritel, ' Le Naturaliste,' vol. xvi, 1002, p. 70, as tliis sjx'cics, iiiijiriu-s to be some- 

 what like Nymphaster innrf/ivatiis. 



CuPi'LASTER PAiPER, Fiir, 1893. ' Arch. Lande.'idf. 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.
