THE DISCOBOLI. 43 



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

 was originally published, it is given in that shape. 



" Cyclopterus Stelleri. 



" C. tuberculis osseis dorsalibus simplici serie ante pinnam dorsalem. 



" Cyclopterus glaber, acetabulo rugoso iutra pinnas pectorales, Steller. obs. ichth. manuscr. 



" Raro in mari Camtschateam alluente, prsecipue circa portum SS. Petri et Pauli capitur. 

 Stellerus tantum e siccato speciinine descripsit et a Camtsehadalis acceperat : banc speciem 

 in tantam magnitudinem excrescere, ut scaphas eoruni evertere valeat, ideoqae ab illis timeri ; 

 de qua fabula ipse dubitat Ipsam Stelleri descriptionem propono: 



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

 crassus, a eapite ad caudam forniam ovalem obtinebat. Colore erat nigricante, undique 

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

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

 Dentes ad oras utriusque mandibular exigui " (addo e specimine sicco Musa?i Petropolitani : 

 inrequales, obtusiusculi, inordinati ; in superiore maxilla in ora tubereuliformes, 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 appendicula mobilis pro lubitu 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 caudre initium pergit. Pinnm postbranchiales 

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

 acetabulum utrinque ambiunt, in summitatc concrete, nee multum solutse sunt. Pinna post 

 anum semuncia 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-E. 



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. Pseudobranchice 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,
