front of anal; several of those farther back bifurcate, each bearing sev- 

 eral fine interhaemals, each with a slender ray ; vertebrae smaller behind ; 

 no anal spine. 



Dorsal rays about 75, the fin low, beginning over the eye; the rays 

 all very slender, the short anterior ones turned forward and inserted 

 much before the enlarged neurals ; ribs few, short, hair-like. Anal 

 rays about 57, not certainly counted. Ventrals with about 5 rays, 

 inserted far behind eye, apparently just before pectorals, which are oblit- 

 erated; caudal peduncle short. Caudal moderate, rounded, the hypural 

 as in EVESTHES, made up of slender coalescent neurals and haemals, 

 the surface, therefore, strongly striate. 



The species is named for Theodore J. Hoover, Professor of Mining 

 in Stanford University. 



Zororhombus Jordan, new genus. 

 (Type: ZORORHOMBUS VELIGER Jordan.) 



A near ally of the living genus BOTHUS Rafinesque (RHOMBUS 

 Cuvier), differing in the excessively high dorsal fin and rather more pos- 

 terior insertion of the ventrals. 



Form broadly and regularly elliptical, the depth two-thirds the length 

 to base of caudal ; eyes on the left side, mouth large, terminal, with coni- 

 cal teeth. Vertebrae small, deeper than long, 37 in number. Neurals 

 strong, two interneurals, each supporting a ray between each pair ; inter- 

 haemals similar, the anterior very oblique. Dorsal beginning on head, 

 much elevated posteriorly, the longest rays two-thirds length of head. 

 Dorsal rays about 80 ; anal about 65 ; ventral separated from anal and ex- 

 tended along ridge of abdomen, a little in advance of pectorals, the rays 

 6 or 7. Caudal separate from dorsal and anal, the peduncle short.

22. Zororhombus veliger Jordan, new species. 



(Plate XXVII) 



Type No. 230. A flounder, 8*4 inches long, fairly perfect. Head 

 2% in length to base of caudal; depth l 1 /^. Body very deep, broadly 

 elliptical, the dorsal and ventral outlines corresponding. Head large, its 

 outline regular ; mouth large, terminal, the lower jaw prominent. The 

 maxillary a little more than half head; jaws with moderate, conical teeth, 

 a few present; opercle moderate, striate. Vertebrae rather small, about 

 15 + 25 = 37 in number, rather deeper than long, moderately grooved, 

 each with a strong, straight neural spine, about a fourth of depth of body, 

 and each corresponding to a pair of interneurals of about the same 

 length, each of which in turn supports a dorsal fin ray. Occasionally a
