THE NAUTILUS. 139 
good latinist he naturally would not. His genus-name was 
Brazilia. And so in his judgment and on the face of Mr. 
Greger’s impeachment, Brasilica had a right to live. Alas! 
neither did I use the term Brasilica, but Brasilia; and here I 
am, mutatis mutandis, just as bad a trespasser on Dr. Buckman’s 
preserve as if Mr. Greger’s commentary had been right. Who 
is to decide in this very delicate point on nomenclatorial ethics, 
whether upon an indictment false and disproved, I can be con- 
victed and fined. Perhaps it may be seemly for me to intimate 
that it is polite, when practicable, to permit an author to him- 
self correct his errors when they are shown to him. If he will 
not, then he is beyond grace. 
Doctor Dall, in his great wisdom, disposes of the matter thus: 
(Letter of February 21, 1921.) 
‘‘There is no Brasilica Clarke. Ergo, Brasilica Greger = 0. 
Chapadella Greger = Brasilica Greger = 0.”’ 
In the presence of this formula I propose to rechristen this 
brachiopod genus with the name Brasilina.—JoHn M. CLARKE. 
Liguus at Marco, FLoripa.— Marco, as you know, is a set- 
tlement at the north end of Key Marco, or Marco Island. 
When we were collecting Liguus in 1904-6-7, we found none 
at Marco, and the inhabitants knew of none there then, though 
the tree snails were remembered as having been at Marco some 
years before. Also, a man told us he had in the past found 
‘*blue snails’? near Marco and had been in the habit of ship- 
ping them to a curio dealer in Key West. He gave me the 
dealer’s name and address. 
We carefully examined the trees where the man reported the 
discovery of the blue Liguus but we found no snails of any kind 
there. Now (January, 1921) Albert Addison tells us that his 
son Chester, some weeks ago, saw snails having blue stripes on 
them in a thicket in sight of the houses of Marco, the same 
place I think where the man years before spoke of having found 
blue snails. 
We searched carefully this thicket, which now is small, and 
found some Liguus there, which I am sending you by insured 
parcels post [Liguus fasciatus roseatus] but none of the blue 
variety, as you will see.
