I have copied the foregoing description from Mr. Matthews's note books 

 because he has retained the diagnosis in tlie epitome of the species of this genus. 

 But I suspect that the discovery of abundant specimens of 0. perpusiUits in the 

 West Indies induced Mr. Matthews to sink this name altogether ; especially as he 

 omitted the name from the systematic list, and also did not leave any description 

 in his MS. The specimens in his own collection labelled with these two names 

 seem to belong to the same sjjecies. — [Ed.]
