and without tentacles; body perfectly smooth; lateral line complete; 

 pores large, the anterior nine with tentacles which are simple, bifid 

 or trifid. Preopercular spine long, simple, and with a perceptible 

 upward curve. Mouth small; maxillary extending to a vertical 

 passing between anterior edge of orbit and pupil. Teeth in broad 

 bands on jaws, vomer, and palatines. 



Dorsals separate; outline of spinous dorsal slightly concave, the 

 length of highest (anterior) spines contained about 2.3 times in the 

 head; all but the last three anal rays large and fleshy, the membrane 

 deeply incised between them; height of longest anal rays 2.5 in head; 

 last dorsal ray connected by membrane with caudal peduncle, the 

 last anal ray free posteriorly; both dorsal and anal falling far short 

 of base of caudal when depressed. Tip of pectoral reaching a vertical 

 through base of first anal ray when depressed; lower seven pectoral 

 rays fleshy, the membrane deeply incised between them; all the rays 

 simple. Ventrals 2 in head, not reaching anal opening. Caudal 

 rounded; 1.4 in head. 



In spirits the color is almost plain, a faint dusky band being 

 suggested below the spinous dorsal, and two similar ones below the 

 soft dorsal; tentacles of the lateral line black; orbital flap dusky. 

 Spinous dorsal dusky, with two indistinctly outlined light spots; 

 soft dorsal with about seven oblique, dusky bars; anal with similar 

 bars which are broader and more numerous; upper and lower rays 

 of caudal with four or five elongate, dark spots which are faintly 

 continued as bars on the fin. Pectorals with narrow, irregular, 

 dusky bars. Ventrals immaculate. Head with a narrow, dark line 

 curving from tip of snout beneath nostril and passing backward 

 below eye; another beginning at posterior margin of eye and extending 

 across preopercle to base of spine. 



Type. — Cat. No. 68240, U.S.N.M., from Same, Japan. A cotype, 

 No. 21426, Stanford University collection, is like the type in all 

 particulars except that there are 15 dorsal rays and no tentacles at 

 tips of nasal spines. The cotype is also from Same. 



BERO ZANCLUS, new species. 



This species differs from Bero elegans in having a markedly slender 

 body and no multifid tentacles on the head, there being a pair of 

 slightly fringed flaps above the eyes and but one pair of small, simple 

 tentacles on the occiput. The intromittent organ is much smaller 

 and more slender in B. zanclus. 



Head 2.8 in length to base of caudal; depth 5.8; depth of caudal 

 peduncle 13.5; eye 4.5 in head; maxillary 2.1; snout 3.9; interorbital 

 space 15; D. IX, 15; A. 15; P. 15; pores in lateral line 38. 



Body elongate, tapering gradually from head to caudal peduncle; 

 snout rather pointed; lower jaw included; eye large, the diameter 

 about equal to length of snout; maxillary extending to a point below
