In the eleven different forms of Aluco instanced, would it 

 not be equally (and perhaps more) to the purpose to write

 with names which do not describe such values. 



Aluco Jiammea niyresceiis, I humbly think, would be better 

 adapted for use in the field if written Aluco Jiammea, 

 St. Vincent, simply, with as much descriptive matter after- 

 wards as might till a page, if necessary ! ! 



Yours &c,

 facts relating to the use of the names Tardus musicus and 

 Tardus iliacus by Linnaeus. Mr. Hartert, in the last number 

 of this Journal (above, p. 431), has pointed out that, ac- 

 cording to the brief "diagnoses" in the tenth edition of 

 Linnaeus's ' Systema Naturae/ the name Turdus musicus
