Type.—Imperfect fish; Paleontological Museum, Munich. 
Six examples of this species are preserved in the British Museum, four in the 
Bayet Collection of the Carnegie Museum, one of which is in counterpart. These 
are cataloged as Nos. 4007, 4314, 4357, and 4357a, 5240. In No. 4357 the ver- 
tebral column is displayed to advantage and seen to consist of twenty-one centra. 
Suborder THORACOSTEI. 
Under this head Swinnerton,‘ following Smith Woodward’s suggestion, has 
proposed to unite the Lophobranchs of Cuvier with the Hemibranchs of Cope. 
As remarked by Boulenger in the volume on fishes in the Cambridge Natural 
History, “the structure of the Lophobranchs (Solenostomide and Lyngnathide) 
shows that these fishes are only extremely specialized forms of the group of which 
the Sticklebacks are the well known type, and the character of the ‘tufted’ gills 
alone is surely not of sufficiently great importance to warrant the retention of the 
Lophobranchii as a division equivalent to the suborders adopted in the present 
classification.” 
The diagnostic character of this group, which, according to Mr. Regan, may be 
related to the Scombresocide, is the presence of a large dermal plate on each side, 
which in the adult is codssified with the coracoid and anteriorly united by suture 
to the clavicle. There are two well-marked divisions, the Gasteroidei and Aulo- 
stomatoider. 
Family Fisrutarima (Cornet Fishes). 
Aulostoma, by some regarded as type of a distinct family, Fistularia (‘Trumpet 
Fish” or ‘‘Flute-mouth” of recent faunas) and Urosphen are the only known repre-
