Bulletin of the Bureau of Fisheries . jaro. Cranium of Lopholatilus, left lateral aspei therefore seem best to separate Malacanthus opo its allies and It would therefore seem best to separate Malacanthus from the threeother genera and consider them as forming the family Latilidse,, as proposed bvDoctor Gill. A still more marked difference exists between Latilus andIInIIn/must, /• in the fact that thelatter docs not possess a myo-dome and also lacks the basi-sphenoid. The skull of Bathy-mastt r is smooth, depressed, andhas a small supraoccipital shutout from the foramen magnum;the vertebral column comprisesIf thoracic and 38 caudal ver-tebrae besides a Hemivertebra,this being double the numberfound in any of the arrangement of the para-pophyses in Bathymaster is alsoquite different from that in theother genera; there is a closedcanal beneath the eleventh to. Cranium i Lopholalihis, posterior aspect. sixteenth thoracic vertebrae, formed by the inward extension of a process from theparapophysis of either side, so that these are united below the centra. Bathymasterfurthermore presents a peculiarity in the shoulder girdle, having the hypocoracoidprolonged beneath and in contact with the fourth, or lowest actinost, while in the 86 BULLETIN OF THE BUREAU OF FISHERIES. majority of fishes there is a considerable gap between the lowest actinost andthe projection of the hypocoracoid. Consequently Bathymaster must be consideredas quite distinct from any of the other genera herein discussed, entitled to the rankof a family, and only distantly related to the Latilidaj.
