Oken, who makes the Lernaeidea a ‘‘ Sippschaft ” of the 
‘“‘ Armwirmer,” gives the following definition of the family :— 
“Leib walzig und unformlich, kein Unterschied zwischen 
Brust und Bauch, hinten meist freie Eierschniire, geiself6rmig 
oder als Saum einer Haut, keine Stummelfiisse, keine Fiihler, 
keine Augen, kein Riickenschild, Schmarotger.”” The modern 
definition is given in Mr. Bassett--Smith’s exceedingly useful 
summary. That summary, however, is limited to the genera 
and species parasitic on fishes. It does not, therefore, mention 
Ive balanoglosst, Mayer, or Pennella balaenopterae, Koren 
and Danielssen. It may be added that, according to Richiardi, 
Atti. Soc. Toscana, Vol. II., p. 190, 1876, Cornalia’s Taphrobia 
pilchardi, described in Atti Soc. Ital. Sci. Nat., Vol. XVIII., 
fasc. 2, p. 197, is identical with, but of later date than Heller’s 
Peroderma cylindricum. It should also be noted that in 
1864 Kroyer described a genus Therodamas, not Therodamus.
