The following an1 its branches: a. A vessel at the ventral end of the Hist branchial arch which divides into thenutrient artery to this arch (5, fig. L6) and into branches which go to the cranial partof the niusculus sternohyoideus. (.£, fig* L6.). Fig. 6.—Efferent branchial vessels of tile-fish, with circulus cephalicus. Ventral aspect, natural size. On theleft side the hyoidean and direct afferent pseudobranchial arteries are shown; on the right side the efferentpseudbbranchia] artery. b. An anterior and a posterior branch shortly after passing through the fora-men at the ventral end of the ceratohyal. The anterior branch (6) corresponds tothe lingual artery of Wright (1885) and supplies the niusculus geniohyoideus andstructures on the floor of the mouth; it terminates in two vessels which accom-pany the rami of the dental bone. The posterior branch (?) is somewhat smallerthan the anterior and runs caudad over the lateral surface of the ceratohyal tosupply the branchiostegal region. c. Two branches where the artery passes through the fissure between the quad-rate and symplectic; the larger/anterior branch (8) runs craniad and divides into The pseudobranch of the tile-fish consists of from
