but 1^ times length, of snout, and the least interorbital width is 11 or 12 

 times iu head. In levins euryojys (ootype. No. 45367, U. S. Nat. Mus.), the 

 eye is 2^ times in head and twice the length of the snout, and the least 

 interorbital width 16 times in head. It does not seem probable that the 

 species will vary to that extent. Maxillary reaching middle of pux>il, 

 2i in head. Upper preopercular spine slender, forked at tip, directed 

 upward and backward, the second and third spines simple, slender, the 

 second directed downward and backward, the third downward and for- 

 ward. Interorbital space shallowly grooved, the groove widening back- 

 ward into an occipital depression bound<'d in front by the somt^what 

 elevated interocular space, laterally by the occipital ridges; sujjraorbi- 

 tal rim elevated in front and behind; occipital ridges lf)w, broad and 

 rounded anteriorly, becoming narrower and more crest-like posteriorly. 

 In addition to the prickles and plates already mentioned, there is a band 

 of spinous scales behind axil of j)ectorals. Spinous dorsal low, the long- 

 est 8j)ine 2i in head, the longest ray of soft dorsal 2 in head ; pectorals 

 reaching beginning of horizontal portion of lateral line, the lower rays 

 thickened, their membranes incised; veutrals short, scarcely reaching 

 vent. Anal papilla large. Color in spirits; light brown above, with 4 

 blackish cross bars, 1 under spinous dorsal joining the dark axillary patch, 

 2 under soft dorsal and 1 at base of tail merging into the uniform deep 

 brown of the under parts ; head light brown above and below ; subocular 

 ring dark brown, this streak widening forward and crossing upper and 

 lower lips ; a small patch at base of exposed portion of maxillary ; opercle 

 blackish ; upper half of pectorals light, with or without a Ijrown basal 

 bar, the distal portion indistinctly barred with light brown; lower half 

 of pectorals, and all of veutrals dark brown, or black; dorsals blackish, 

 darkest above the cross bars on back; anal black; caudal whitish, dusky 

 above toward tip. Bristol Bay, Alaska, where numerous specimens, ,50 

 to 110 mm. long, were obtained by the Alhatfosn at depths of 109, 351, 

 350, and 406 fathoms, respectively. (Gilbert.) {rkiiialis, near, to Icelua

Head 3 to 3^ ; depth 6. D. VII or YIII, 23 or 24 ; A. 19 ; P. 16 ; V. 13 ; Lit- 

 eral line 43 to 46. A deep-water species, with conspicuous mucous canals 

 and pores, thin cranial boues, and rather plain blackish coloration. In 

 other characters it stands somewhat intermediate between Icelus hicornis 

 and Icelus spinUjer. The dorsal plates have the serrulated cross ridge 

 of Icelus hicornis, the occiput is shallowly concave, with low bound- 

 ing ridges ending behind in strong spines, and the posterior rim of the 

 orbit is elevated and denticulated, as in Icelus spiniger. In its anterior 

 portions, at least, the series of dorsal plates is accompanied above by 

 a more or less irregular row of smaller plates, which alternate with the 

 larger plates, and bear each a small spine. Caudal peduncle long aiul
