2567. BOLLMANNIA OCEliLATA, Gilbert. 



Head 3i to '6% in length; depth 4i. D. VIT-14 or 15; A. 14; scales 27. 

 Very close to Boll monnia chlaniiidcs, differing- from the latter constantly 

 in the following respects: The eye is larger, 3 to 3i in head (3| to 4 in 

 chlamjidcs) ; the filamentous rays of spinous dorsal are much longer, reach- 

 ing in adults, when laid back, to or nearly to end of base of soft dorsal, 

 1| to Ij times length of head; rarely the filamentous dorsal rays are little 

 more elongate than in chlamydes. Teeth in a narrow band in each jaw, 

 the outer series in upper jaw, and both outer and inner series in lower 

 jaw enlarged, but not canine-like; maxillary not reaching vertical from 

 middle of pupil, i length of head; interorbital width less than | diameter 

 of pupil; opercle short, its length being less than the diameter of the 

 eye; pectorals nearly as long as head, a trifle more than length of ven- 

 trals, which scarcely reach vent; caudal much longer than head in adults, 



7 or 8 scales before dorsal. Black spot on posterior part of spinous dorsal 

 jet black, conspicuously ocellated with white; a black streak along lower 

 margin of caudal, including several of the lower rays, and running from 

 base to tip of fin; no dusky bars visible on sides in any of the types; 

 fins dusky; membranes uniting outer rays of ventrals white instead of 

 black, as in cUlamydes; no black spot at base of caudal; branchiostegal 

 membrane with a medial black streak; anal blackish. Numerous speci- 

 mens from the northern part of the Gulf of California, at Albatross Sta- 

 tions 3031 and 3035, in 30 and 33 fathoms. This species may vary into the 

 typical cJdamydes, but the material before us does not justify us in so 

 identifying it. (Gilbert.) {ocellaius, ocellated.)

2568. BOLLMANNIA CHLAMTDES, Jordan. 



Head 3A (5 to 5^ in total) ; depth 4+ (6f to 7). D. VII-15; A. 15 ; scales in a 

 longitudinal series about 28, 8 or 9 in a cross series at vent. Body rather 

 robust, compressed; head large and heavy, its profile evenly curved; 

 mouth very large, oblique, the lower jaw projecting; maxillary reaching 

 to opposite pupil, 2t to 2f- in head; teeth small, sharp, in several series, 

 the outer, especially in lower jaw, somewhat enlarged; eye longer than 

 snout, 3f to 4 in head; interorbital area very narrow, concave, its least 

 width about ^ of eye or almost equal to pupil ; scales very large, ctenoid ; 

 little reduced on breast and nape ; about 8 before dorsal, w^here they are 

 little smaller than on body; top and sides of head with large scales; 

 scales on cheek in 4 rows ; 2 rows on upper part of opercle ; the scales 

 on head lost in some of the specimens; dorsal spines slender, filamentous, 

 fifth longest, li in head; first 2 in head, last 3i to 4; first soft dorsal ray 

 2| in head, the antepenultimate longest and about equal to head; first 

 anal ray equal to snout, the antepenultimate IJ in head; middle caudal 

 rays very long, somewhat more than i length of body ; pectorals 1^ in 

 head; ventrals IJ. Color olivaceous, darkest above; scales with a few 

 black dots, some of the posterior occasionally dark edged; sides with 



8 or 10 obscure dusky vertical bars, which are narrower than the inter-
