Note. — I may add that an exhaustive article on the anatomy of 

 the genus, entitled " Beitrag zur Kentniss der Gattung Harpa,'' by 

 Dr. R. Bergh, was published in 1901." 



And, with regard to the fossil forms, the " Essais de Paleontologie 

 Comparee," by M. Cossmann, 1899, livr. iii., pp. 72-79, contain an 

 extended account of the various species, of which only a selection 

 was given in the fust portion of this paper, Dr. Tate and others 

 having added many in more recent years to our lists.
