no. 2075. FISHES FROM SOUTHERN CALIFORNIA— GILBERT. 369 



CATAETYX RUBRIROSTRIS Gilbert. 



Three specimens obtained at the following stations : 



LYCODAPUS DERMATINUS Gilbert. 



Reexamination of the type of this species indicates that it is a well- 

 marked form of which no second specimen apparently has been ob- 

 tained. It belongs at the fierasfer end of the series, having fine teeth 

 in the jaws, disposed in comparatively narrow bands, all concealed 

 when mouth is closed ; it has several teeth on the vomer and has com- 

 paratively slender gill-rakers, which are longer than they are wide at 

 the base, and are 10 or 11 in number on anterior limb of outer gill-arch. 



The vomerine teeth are characteristic, being stronger than any of 

 the other teeth. They are 6 in number, canine-like, curved, the 

 median teeth directed downward, those at the sides strongly out- 

 ward and backward. In L. fierasfer, the vomerine teeth are minute 

 and are typically 10 or 12 in number. Palatine teeth in L. dermatinus 

 small, almost 10 in number, a wide interval separating them from the 

 vomer. The fin rays apparently are less numerous in L. dermatinus 

 than in any other species, the dorsal containing but 70 rays.
