36 ANNALS OF SCOTTISH NATURAL HISTORY 



must therefore drop, as no genus can be founded on the 

 fragment of which a section is figured in Agassiz's larger work. 



Cosmaeanthus Maleolmsoni, Agassis. " Foiss. Foss. v. gres rouge," 

 p. 121, tab. 33, Fig. 28. Previously figured by P. Duff, op. at. 

 Plate VII. Fig. 5, as a "dorsal spine." Scat Craig. 



NOTE. The nature of this fragment is still doubtful ; it does not 

 seem to be a selachian spine as supposed by Duff and Agassiz. 

 By Pander it was interpreted as the outer penultimate marginal 

 plate of the lower part of the arm of an Asterolepid, but its 

 sculpture is different from that on the arms of Botliriolepis major, 

 the common Asterolepid of the Scat Craig deposit.
