THE DISCOBOLI. 43 



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

 was originall}'^ published, it is given in that shape. 



" Cyclopterus Stelleri. 



" C. tnberculis osseis dorsalibus simplici serie ante piunam dorsalem. 



" Cyclopterus glaber, acetabulo rugoso intra piiinas pectorales, iSteller. obs. ichth. manuscr. 



" Raro in mari Camtscliatcam alluente, prsecipue circa portuui SS. Petri et Pauli capitur. 

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

 in tantara magnitudinem excrescere, ut scaphas eorum evertere valeat, ideoque ab illis tinieri ; 

 de qua fabula ipse dubitat. Ipsam Stelleri descriptionem propono : 



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

 crassus, a capita ad caudam formam ovalem obtinebat. Colore erat nigricante, undique 

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

 dibula inferior superiore dimidia uncia (rhenol.) longior, utraqne bifida. Lingua crassa. 

 Denies ad eras utrinsque mandibulfe exigui " (addo e specimine sicco Mussei Petropolitani : 

 insequales, obtusiusculi, inordinati ; in superiore maxilla in era tuberculiformes, interius 

 autem majores). ^'Oculi exigui, in summis lateribus capitis, ultra unam unciam ab extimo 

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

 cum membrana branchiostega non movetur, nee aperitur, sed ostio sphajrico saltern in 

 lateribus patet, et supra hoc ostium ap^yendicula mobilis pro luhitu clauditur et aperitur, 

 eadem ratione ac in Cobitide T;enia. Anus tertiam partem corporis inchoat. Pinna in 

 dorso unica, in medio dorso incipit et fere ad caudse initium pergit. Pinnce 'postbranchiales 

 pectoralibus aliquanto altiores. P. pectorales, quas CI. Artedi veutrales perperam dicuntur, 

 acetabulum utrinque ambiunt, in summitate concret£e, nee miiltum solutfe sunt. Pinna post 

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

 Acetabxdum intra p. pectorales (ventrales, maguitudine denarii misnici). — Interna in sicco 

 pisce deerant." 



LIPARIDID^. 



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- 

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

 one single. Pseudobranchite 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,
