a minute twig to the skin adjacent, presumably for the small 
pit organs over the lachrymal bone. The remainder of the 
buccal nerve runs forward under the nasal sac to distribute to a row 
of five or six large pit organs near the anterior nasal aperture 
and doubtless to small pit organs also in the same _ vicinity, 
though the latter point was not actually observed. Together 
these larger organs form arow corresponding to the ‘‘maxillary 
” or organs 0, c, d, e, f, of Menida and to the lines 
of naked organs in the corresponding position of Lophius 
(GUITEL, ’91), Batrachus (CLapp, ’99), and Gadus (COLE, ’98, 
p. 158 and Herrick, ’0o p. 281). Attis has previously men- 
tioned this line (’97, p. 629). StTanwnius (49, pp. 41, 43) and 
JuGE (99) affirm that the r. buccalis is absent in Silurus, which 
of course can only be interpreted to mean that it is not ana- 
tomically distinct. The latter author mentions in his summary 
(p. 159) that the suborbital lateral line canal is innervated by a 
twig from the inferior branch of the r. ophthalmicus superficialis 
facialis (JUGE relegates this nerve, however, to the trigeminus 
and calls the true r. ophthalmicus superficialis V the ophthal- 
micus profundus). Unfortunately he does not give, so far as I 
can find, a more exact description of this nerve. If the fact is 
as stated, it simply means that in Silurus the dorsal and ventral 
branches of the dorsal lateralis root of the facialis separate into r. 
ophthalmicus superficialis VII and r. buccalis far distal to their 
‘common foramen instead of intra-cranially asin teleosts generally.

This nerve has been examined and briefly reported upon by 
my pupil, Mr. WorkKaN (’00, p. 403), his studies having been 
based upon the same sections as those now under consideration. 
Its fibers separate from the dorsal side of the ganglionic com- 
plex (see Fig. 2) and are purely lateralis fibers with no admixture 
of other components. Emerging from the cranium by a separate 
foramen, it supplies all of the organs of the supra-orbital canal 
(except the fifth organ, supplied by the r. oticus) and small pit 
organs along the course of this canal. The general arrangement
