2. LIPARIS. 163 



to the pneopereulum. Gill-openings reduced to a lunate foramen on 

 each side of the back. Ventral disk small. The dorsal commences 

 a little behind the gill-opening. Brown-dotted; a silvery streak 

 from the upper jaw through the eye and opercles. 



5. Liparis cyclopus. 



D. 35. A. 30. C. 12. 



Caudal fin entirely free from dorsal and anal; the latter com- 

 mences in the vertical from the seventh dorsal ray ; pectoral margin 

 with a notch, some of the lower rays being produced ; ventral disk 

 ovate, its length being less than one-half of that of the head. 



a. Fine specimen. Esquimault Harbour. Presented by Lord John 

 RusseU. 



This species agrees in nearly every respect with Liparis vulgaris, 

 from which it differs in the following points besides those men- 

 tioned : — 



The greatest depth of the body is nearly one-sixth of the total, 

 the length of the head nearly one-fifth. The skin is tougher and 

 more firmly adherent to the body. The head is flat above, the nape 

 of the neck being scarcely prominent. The nostril is a short tube, 

 situated nearly midway between the eye and the upper lip. The 

 pectoral extends only to the vertical from the anal papilla, and the 

 dorsal fin commences yet more backwards. The teeth are small, 

 with three lobes. Infraorbital extending to the pneopereulum. 



The colour is brownish-olive, with darker spots, more conspicuous 

 on the fins than on the body. Belly reddish. 



The length of the specimen described is 45 lines. 



The following species require further examination : —

 Lipans gelatinosus, Cuv, H^gne Anim. 



B. 7 ? D. plus quam 50. A. ca 45. C. 6. Case, pylor. 48. 

 Vert. 64. 



Vertical fins contiguous. Ventral disk small, supported by a bi- 

 lamellated cartilage, which descends from the throat. 



Pallas has given a description and figure from the MS. of SteUer 

 and from a specimen in the St. Petersburg Museum : — 



Body oblong, compressed, thicker towards the head and thinner 

 towards the tail, semitransparent, exceedingly soft, like jeUy. Head 

 thick, somewhat depressed, flat on the vertex, and convex between 

 the orbits. Eyes directed upwards ; nostrils in the middle between 

 the margin of the mouth and the orbit, with a small tubular append- 

 age ; a series of pores along the upper lip towards the gill-opening.
