THE DISCOBOLI. 43 



As its value to an investigator is greatest in the exact form in whicli it 

 was originally published, it is given in that shape. 



" Cycloptkrus Stelleei. 



" C. tnberculis osseis dorsalibus simplici serie ante pinnam dorsaletn. 



" Cyclopterus glaber, acetabulo nigoso intra pinnas pectorales, Steller. obs. ichth. manuscr. 



" Raro in mari Camtschatcam alluente, prtecipue circa portum SS. Petri et Pauli capitur. 

 SteUeriis tantum e siccato specimine descripsit et a Camtschadalis acceperat : banc speciem 

 in tantani magnitudinem excrescere, ut scaplias eorum evertere valeat, ideoque ab illis tiuieri ; 

 de qua fabula ipse dubitat. Ipsam Stelleri descriptionem propono : 



Descr. "Oblatus piscis dodrantem longus erat, in diametro nbi crassior, quatuor uncias 

 crassiis, a capite ad caudam formam ovalem obtiuebat. Colore erat nigricante, undiqne 

 glaber, in medio dorso tantum series tuberculorum aderat, usque ad pinnam dorsalem. Man- 

 clibula inferior superiore dimidia uncia (rbenol.) longior, utraque bifida. Lingua crassa. 

 De)ites ad oras utriusque mandibuh? exigui " (addo e specimine sicco Musa?i Petropolitani : 

 iniequales, obtusiuseuli, inordinati ; in superiore maxilla in era tuberculiformes, interius 

 autem majores). "Oculi exigui, in summis lateribus capitis, ultra unam uiiciam ab extimo 

 rostro remoti. Valoa branchialis valde magna ; ossicula brancliiostega sex at vero valva 

 cum membrana brancliiostega non movetur, nee aperitur, sed ostio sphifirico saltern in 

 lateribus patet, et supra hoc ostium ap2yendicula mobilis pro lubitu clauditur et aperitur, 

 eadem ratione ac in Cobitide Trenia. Amis tertiam partem corporis incboat. Pinna in 

 dorso nnica, in medio dorso incipit et fere ad caudre inilium pergit. PinncB postbranchiales 

 pectoralibus aliquanto altiores. P. pectorales, quae CI. Artedi ventrales perperara dicuntur, 

 acetabulum utrinque ambiuut, in summitate concretse, nee multum solutse sunt. Pinna post 

 anum seniuncia ab ano incipit, ac deficit ubi p. dorsi. Cauda post anum subito gracilescit. 

 Acetabulum intra p. pectorales (ventrales, magnitudine denarii misnici). — Interna in sicco 

 pisce deerant." 



LIPARIDID-ffiJ. 



A greater resemblance to the tadpole is seen in the shape of the 

 species of this family than occurs in either of the preceding families. 

 Forward, the body proper is broad, rounded, and more or less depressed ; 

 backward, rather more than half of the total length is made up by the 

 much compressed post-abdominal section. The head is short and broad, 

 the snout wide and blunt, the mouth of moderate width and nearly or 

 quite terminal position, and the eyes, medium to very small, are lateral. 

 Teeth tricuspid to simple, very small, villiform, in a number of rows form- 

 ing a pavement or card. Branchiostegals six. Gills, three double and 

 one single. Pseudobranchias present, said to be lacking in one species. 

 Gill openings small, above the base of the pectoral. Pectorals broad, the 

 bases extending forward under the throat. Ventrals, when present, below 

 the head, between the pectorals, transformed into a small adhesive disk,
