head, appear to be more elongate than in old individuals. 

 The same is the case with the tail, measured from the gill- 

 opening. It appears to have a greater number of tentacles on 

 the skin, especially on the pectorals; the margin of the 

 pectorals appears to be finely ciliated. D. 11, (dorsal fin with 

 eleven rays.) The differences from old individuals as we find 

 them stated here by Valenciennes, agree, in the chief points, 

 with our observations; but it is evident that Valenciennes took 

 his notes from a mutilated specimen, in which the delicate 

 appendages of the fins had been lost or shrivelled up, either 

 previous to or during its preparation in spirits. The two 

 specimens observed by Diiben and Keren, on the western 

 coast of Norway, were much more perfect; they were 94 mm. 

 and 78 mm. long, and exhibited such remarkable differences 

 from the specimens commonly observed, that those naturalists 

 were induced to describe them as a new form, under the 

 name of Lopliius eurijpterus, a species which we find adopted 

 by Professor Nilsson, in his work, 'Skandinavisk Fauna.' 



"The view of the fish represented is the most depressed one 

 possible. 



"I extract the following notes from the very detailed des- 

 cription: The head is described as broader than long, less 

 depressed than in Liphius piscatorius , its length (from the 

 extremity of the snoat to the posterior margin of the gill-cover) 

 being one half of that of the remainder of the body, the 

 caudal fin not included. The dorsal spines are comparatively 

 short, the length of the first being only half of that of the 

 second, or one fifteenth of the total length of the fish; the 

 first terminates in a transverse cylindrical knob, which is pro- 

 vided with minute cilia; the two others have alternate fringes 

 on both sides. The spines which form the continuous dorsal 

 are similarly fringed; and the rays of the soft dorsal project 

 very slightly beyond the membrane. The pectoral is exceed- 

 ingly broad, and extends beyond the origin of the anal. The 

 ventral also is broad, and can be expanded like a fan." The 

 disproportion of this fin, however, in the two individuals observed 

 is very remarkable. It is nearly twice the length in the larger 

 one that it is in the smaller. The pectoral also is absolutely 

 as well as relatively larger in this specimen than in the one 

 figured, a difference by which perhaps the sexes are dis-
