1 G4 DISCOBOLI. 



Lips thick ; cleft of the moutli directed upwards, as in Uranoseopus, 

 but with the lower jaw less prominent. The jaws, the palate, and 

 the pharynx are rough Avith teeth. Four gills on each side ; seven 

 branchiostegals. The gill-opening is reduced to a slit above the 

 base of the pectorals. Pectorals large, very broad, commencing at 

 the throat, the inferior part of their bases being parallel, ascending 

 to the gill-opening ; they are composed of about thirty rays, the in- 

 ferior of which are very short and not connected by a membrane. 

 The dorsal and anal fins are contiguous with the caudal ; they com- 

 mence a little behind the middle of the body and are composed of 

 feeble rays. The jugular disk is situated between the pectorals, in 

 ft'ont of the vent ; it is very small, soft, supported by a bilamellated 

 cartilage which descends from the throat. The vent is between the 

 pfictorals. Caudal small, six-rayed, llose-coloui-ed ; the vertical 

 fins violet ; gill-cavity black. 



Steller adds the following anatomical details : — 



Ovarium orbicular, containing eggs of the size of a pea. Liver 

 large, di\aded into four lobes, of a whitish colour ; gall-bladder ab- 

 sent. Sijleeu triaugidar, brown. The stomach is three times as 

 wide as the oesophagus ; forty-eight pyloric appendages, two inches 

 long, and as thick as the wing-feather of a pigeon, in a specimen 

 eighteen inches long. The remainder of the intestinal tract is about' 

 as long as the fish. The urine-bladder is the size of a hazel-nut. 

 The Iddneys are united into one cuneiform mass, commencing near the 

 gills and extending to the anterior portion of the ovarium ; the ureter 

 is single, very wide, flexuous, becoming narrower before its insertion 

 in the bladder. The nervi optici and olfactorti have one common 

 ganglion, from which, first, the former arise, emitting the latter from 

 the angle formed by the nerves and the ganglion (?). Skeleton very 

 slightly osseous. 



Specimens (one of 18 inches long) were found by Steller in 

 Peter and Paul's Harbour.

We are unable to give the specific difierences of this fish, as it 

 is only known to us by the description of Girard, who omits the 

 numbers of the fin-rays, stating, however, that the vertical fins are 

 united. The following is an abstract of Girard's notes, taken from 

 a specimen four inches long : — 



The head is contained about five times in the total length ; the 

 snout protrudes slightly beyond the upper jaw. The longitudinal 

 diameter of the eye enters about five times in the length of the head. 

 The mouth is not deeply cleft, since the maxillary extends but to a 

 vertical line di-avni in advance of the pupil. The lips are flabby. 

 Teeth very small, disposed in transversely oblique series in each jaw. 

 Girard has found onlv four branchiostegals. Dorsal and anal fins
