Fig. 11 Diagram of the relations of the VIII and lateralis roots of Silurus 
glanis; compare figures 5 to 10. 
Nervus lateralis anterior: 
(1) cerebellar tracts. 
(2) fine fibers going to the lobus lateralis anterior. 
(3) two bundles of fine ventrally ascending fibers. 
(4) diffuse fine dorsally ascending fibers. 
(5) circular bundle of fine descending fibers ending beneath the lobus lineae 
lateralis posterioris. 
(6) diffuse bundle of fine descending fibers ending beneath the lobus lineae 
lateralis anterioris. 
(7) coarse fibers probably ending in the substantia reticularis ventralis or 
crossing with fibrae arcuatae internae. 
(8) coarse fibers probably ending in nucleus ventralis VIII (IkKappers). 
Octavus: 
(9) ascending bundle of fibers that probably gives off (a) fibers crossing the 
raphé; (b) fibers piercing the nucleus ventralis VIII (perhaps crossing the raphé) ; 
(c) fibers ending in the nucleus ventralis. 
(10) tract descending directly beneath the crista lobi lineae lateralis anterioris, 
not piercing the nucleus ventralis VIII. 
(11) tract, farther on, descending beneath the crista lobi lineae lateralis ante- 
rioris medially from the secondary VIII root. 
(12) spinal VIII tract. 
(13) second VIII root.
