264 GREGORIO—ERRONEOUS SYNONYMY. [April 15; 
the species, though this may have been chosen to denote the genus. 
For instance, the name of JZya vulsella L. (as a new genus has been 
created) has been changed in Vulsella lingulata. The name of 
Ostrea malleus \.. has been changed in Madleus vulgaris Lamk. 
I have proposed in similar cases to retain the original name of the 
species, which I believe is the more correct. So I have proposed 
to call these species Vulsella vulsella (L.), Malleus malleus (L.). 
My proposition has been accepted by many malacologists. 
Indeed now instead of Péicatula ramosa Lamk. (= Sponottlus plica- 
tus L.), it is better to employ the name Picatula plicata (L.) sp. 
Instead of Lima sqguamosa Lamk, (= Ostrea lima I..) the name of 
Lima lima (1..) sp.; instead of Hippopus maculatus Lamk, 
(=Ostrea hippopus (L.)) the name of Hippopus hippopus (L.) 
Sp:; tc: 
I think that this modification might be conveniently adopted also 
for plants as well as animals. I believe, for instance, it is much 
better to say Zymnus tymnus than Scomber tymnus or Tymnus vul- 
garis. For the same reason I believe it to be much more correct 
to say Malus malus instead of Pyrus malus or Malus communis. 
What I have said for the names of Linné, is also applicable to the 
names of other authors which have been changed, because recent 
authors have chosen the name of the species as a generic name. 
I call the attention of zoologists and botanists to this interest- 
ing innovation. I hope that it will be adopted for plants and for all 
animals, as it has been for the mollusks.
