In the synonymy of Liparis lineata, I have only included the references to 

 the Greenland fish, without, by any means, undertaking to decide between 

 Drs. Kroyer and Liitken, the former of whom considers the Greenland fish en- 

 tirely distinct from the Cyclopterus lineatus of Lepechin, while the latter consid- 

 ers it the same, and also identical with the Liparis vulyaris of Europe, but still 

 retains the name Liparis lineata, as Lepechin first gave the distinctive appella- 

 tion. As, therefore, the nomenclature is not affected, Dr. Kroyer retaining the 

 name Liparis lineata for the Greenland fish, I am glad to be able to leave the 

 controversy in statu quo. 



The discrepancies between the radial formula, especially of the caudal fin, 

 of Liparis valgaris of authors and Liparis lineata deserves attention. Thus 

 Giinther assigns to his Liparis vulgaris D. 35 36, A. 27 28, C. 10 ; Lepechin, 

 to his Cyclopterus lineatus, D. 30, P. 26, A. 28, C. 13 ? ; Kroyer, to his Liparis 

 lineatus, D. 13+21, A. 2 + 29, C. 13, P. 34; and Liitken, to his, D. 36, A. 30, 

 G. 14 ? P. 33. and with the results of the latter two my own observations 

 agree. 



Of thirteen English specimens of the so-called Liparis vulgaris of Yarrell, eleven 

 exhibited little distinct coloration on the body, but the dorsal and anal fins were 

 densely dotted, so as to give to those fins, especially when folded, a blackish- 

 blue hue. The pectorals of some, especially towards the superior margin, were 

 also clouded. In one specimen, the head aud body were distinctly marmorated, 

 and delineations like those represented on the head, body and pectorals of 

 Liparis lineatus by Kroyer, and Ij. lineata by Liitken, were observed, but the 

 dorsal and anal were simply dotted as in the ordinary variety, and the delinea- 

 tions themselves were dark lilac on a yellowish ground. The last one, conse- 

 quently, represented the L. lineatus of Lepechin and Liitken, and the others 

 the L. barbatus of Ekstrom and Liitken. 



Liparis arctica, Gill. 



The greatest height exceeds a third of the total length, while the greatest 

 width is rather less than a seventh ; the height at the end of the caudal pe-
