70 THE NAUTILUS. 
Brasilica Clark 1913. This generic term was erected by 
Dr. John M. Clarke (Monog. do Serv. Geol. e Mineral. do 
Brazil, Vol. 1, pp. 214-216, 1913) with the Centronella? mar- 
garida Derby as the genotype. The use of the term Brasilica 
is not applicative, in view of the fact that it was employed by 
S. S. Buckman in 1898 for a genus of Ammonites, with the 
Jurassic species A. bradfordensis as the genotype. The 
generic term Chapadella is here proposed for the type of loop 
structure exemplified in Centronella? margarida Derby, the 
genotype. Chapada is a small village in Matto Grosso, Brazil, 
near which place H. H. Smith collected the material originally 
used by Dr. Derby in his paper published in the Revista do 
Museu. Rio de Janeiro, 1896.—Daruine K. GREGER. 
ZONITOIDES NUMMUS IN INpDIANA.—In looking over a lot of 
shells collected on Feb. 28, 1904, by the late A. C. Billups 
from Great Miami River drift, Lawrenceburg, Ind., I found 
specimens which I take to be Zomtoides nummus Van., so am 
sending some. This is far out of the recorded range of this 
species so far as I know. The balance of the shells are what 
one would expect from that region. A good many of the Z. 
minusculus have the thickening of the lip, or rather back of 
the lip, ‘‘bourrelet’’ I believe the French call it. This is not 
a mark of maturity, as many of the half-grown shells have it.
