no. 2075. FISHES FROM SOUTHERN CALIFORNIA— GILBERT. 357 



slit, 5.5; distance from tip of snout to anus, 21; to base of first 

 dorsal ray, 30; length of caudal, 13; width of pectoral base, 18; 

 longest ray of upper pectoral lobe, 14; of lower pectoral lobe, 28; of 

 shortest rays in notch, 5. 



Dorsal, 53; anal, 50; pectoral, 28. 



Dorsal profile strongly arched at occiput and nape, the origin of 

 dorsal but little behind the apex of the arch. Profile of head strongly 

 declivous, that of snout nearly vertical; interorbital region trans- 

 versly wide and flat; mouth horizontal, at lower profile, the snout 

 protruding a trifle beyond the premaxfllaries ; maxillaries extending 

 to below posterior margin of pupil; majority of the teeth in both 

 jaws rather short triangular, with a distinct pair of lateral cusps, a 

 few of the teeth at the margin of the band simple. Gill-slit short, 

 confined to suprapectoral area, covered by a long tongue-shaped 

 opercular flap; nostril single, with slightly raised margin; pores on 

 head rather small. Vent well forward, under the posterior margin of 

 cheek. 



Origin of dorsal vertically above anterior part of gill- slit; basal 

 fourth of caudal fin attached to dorsal and anal. Upper pectoral 

 ray on level of middle of eye, the lower rays of the two fins closely 

 approximated under the posterior portion of the eye. Upper pectoral 

 lobe short, wide, and bluntly rounded, scarcely reaching vertical 

 from front of orbit. The three lower rays are short and largely free, 

 the four above it forming a very long narrow lobe, with only the tips 

 free, extending beyond the front of the anal. Above these, the fin 

 is abruptly and deeply notched; the rays in the notch very delicate, 

 but little more widely spaced than the rays above. 



Peritoneum and lining of gill-cavity black, showing through the 

 integuments. Caudal fin and the neighboring parts of dorsal and 

 anal dusky. Eye dark. Head and body otherwise light in color, 

 perhaps reddish in life. 



Only the type known. 



RHINOLIPARIS ATTENUATUS Burke. 



Three specimens of this species were taken at the following stations : 



There seem to be typically 7 rostral filaments, 3 in an upper 

 series, with the unpaired filament on the median line, and 4 in a 

 lower series of 2 pairs. In 1 specimen, the pyloric caeca are 7 in 

 number. The pectoral rays are 21. Branchiostegals 6.
