ronowitsch's work, thus indicating that they should be the homo- 

 logues, respectively, of the nerves called by me in Aiiiia, and also 

 in the present work, the ophthalmicus superficialis facialis, and 

 ophthalmicus superficialis trigemini. The distribution of the 

 branches of the two nerves is not, however, entirely in accord with 

 this supposition. Thus, the so-called ophthalmicus superficialis of 

 Lota is said to supply "den Schleimkanalen der hinteren Knochen 

 der suborbitalen Reihe"; a region innervated both in Aiiiia and 

 Scomber by a nerve that can only be considered either as a branch 

 of the buccalis facialis or of the oticus facialis. Goronowitsch then 

 says, "Einige Zweige innerviren die Schleimkanale des Frontale"; 

 but whether these branches come from the ophthalmicus super- 

 ficialis or from both that nerve and the profundus is not stated. 

 The profundus is said to send a branch to the canal in the antor- 

 bital bone; that is, to a section of canal that lies in a bone that 

 usually forms part of the suborbital chain of bones, and that, in 

 Amia, is innervated by a branch of the buccalis. That there is 

 some error in these several statements seems to me certain, and I 

 assume that the fibers destined to supply the supraorbital canal all 

 come from the stem Trigeminus II. R. From this same stem, Tr. 

 XL R, a branch is said to be sent forward along the floor of the 

 orbit. It is called by Goronowitsch the nervus rostralis and is 

 said to innervate the lateral canal in the suborbital bones, being 

 thus the probable homologue of the ramus buccalis facialis of my 

 descriptions of Amia. It is said to be closely accompanied by a 

 branch of the stem Trigeminus I., which is called by Goronowitsch 

 the nervus maxillaris superior. An independent motor branch, 

 which innervates the adductor mandibulse muscle, is said to arise 

 from the Trigeminus I., and the nervus maxillaris inferior is said 

 to receive its fibers in part from that stem and in part from the 

 dorsal root of the facialis. The entire stem Trigeminus II. H, is 

 said to unite with the ventral root of the facialis, and to then re- 

 ceive fibers from the dorsal root of the facialis and from the stem 

 Trigeminus I., the fibers from Trigeminus I. being said to be 

 possibly motor. From these united nerves the ramus hyoideo- 

 mandibularis is said to arise. 



Trigeminus I. of Lota thus seems to be the homologue of the 

 anterior, or trigeminal root of the trigemino-facial complex of
