12 This species is introduced as a synonym of H. vtlatytts solely on the authority of Dr. Filhol (toe. cit.), hut in the sequel 
is frequently treated as a distinct species : if really distinct II. horbonicus should be referred to it, and perhaps some of the 
other synonyms. (See Gervais, loc. cit., p. 192.)
