Pinna minuta, Gabb, Proc. Phila. A. N. S., 1860, p. 198, PL 3, f. 10, from the Cretaceous of Chile, 

 is apparently the carinal plate of a Scalpellum, and since no species of this genus has been 

 described from this region, it will have to retain the specific name and be called S. minutum. 

 This is an unfortunate name, since the species is of average size, but is another illustration 

 of the bad results which arise from even well-intentioned character names, and not less so 

 of the regrets with which more mature students sometimes have to look back on their juve- 

 nile efforts.
