Its formula is 2-4-1-1 ; that is, the two dorsal rays are simple, the next 

 four bifid, the next one simple, and the ventralmost bihd. The anal 

 has 4 rays, none of wldch is bifid. Its base is considerably shorter 

 than that of the dorsal. The pectorals contam 13 rays, the ventral 

 one of which is bifid. The ventral ray on the left fin is trifid, with 

 one division deeper than the other so that there at first appear to be 

 14 rays in this fin. Directly behind and below this fin is the giU 

 opening, which is 6 mm high. The vent is a short distance ahead of 

 the origin of the anal. 



Remarks. — Regan (1926, pp. 26, 27) has limited the genus Onei- 

 rodes to those members of the family Oneirodidae having the pre- 

 maxillaries not particularly protracted, the illicium near the end of 

 the snout, followed by an isolated simple ray that appears on the 

 middle of the back. To this genus, then, be leaves Oneirodes esch- 

 richtii, noting that 0. niger Brauer and 0. cornutus Gilchrist probably 

 are species of the genus Dolopichthys. Oneirodes hulbosiLS differs from 

 0. eschrichtii in having 13 instead of 17 pectoral rays, 5 dorsal rays 

 instead of 6. From the picture of the latter species given bj'^ Regan 

 (1926, p. 26) the new species differs in having the sphenotic spine 

 posterior to the eye, the maxillary not extending posteriorly to a 

 vertical from the sphenotic spine, the basal bone of the illicium pro- 

 jecting past the snout, in having the above mentioned spine below 

 and behind the corner of the mouth, and in several other characters 

 such as the gill opening extending down only a small distance from 

 the base of the pectoral. The structure and the position of the 

 appendages of the illicium are quite different from those shown for 

 0. eschrichtii. 



It is believed that this is the first example of the genus Oneirodes 

 taken in the Pacific Ocean. Besides Dolopichthys thompsoni Schultz, 

 which lils:ewise was taken by the International Fisheries Commission 

 (Schultz, 1934), this species is the only member of the suborder 

 Ceratoidea that has been taken from the northeastern Pacific Ocean. 



Named in reference to the nearly spherical shape of the body of the 

 fish.
