LYCODES MUCOSUS (Richardson). 



Genus LYCODES, Reinhardt ; Th. Ar/cwS^s (lupo similis). 



Lycodes mucosus : PLATE XXVI., fig. 1-5, nat. size. 

 Radii: Br. 6-6 ; D. 84 ; C. 10; A. 64 ; V. 3 ; P. 18. 



Professor Reinhardt became acquainted with this generic 

 form in the year 1831, on examining a specimen taken from 

 the stomach of a shark at Nennortalik, on the coast of West 

 Greenland, in 60 of north latitude. Subsequently he 

 obtained other examples from Fiskerness, lying under the 

 sixty-third parallel ; and in his ' Ichthyologiske Bidrag og 

 Tillseg til den Gronlandske Fauna/ published at Copenhagen 

 in ]837, he gave a detailed account of three species, viz. 

 Lycodes Vahlii, L. reticulatus, and L. seminudus, with figures 

 of the first two."* These three species are more or less scaly, 

 but Lycodes mucosus has no scales whatever : in this respect 

 it agrees with the Blennius polaris obtained on the coast of 

 North Georgia near the seventy-fifth parallel of latitude, during 

 Sir Edward Parry's First Expedition. Captain (now Colonel) 

 Sabine does not enter into sufficient details to enable us to 

 characterize polaris, but says enough to render it probable 

 that it enters into the genus Lycodes, and if so it agrees with 

 mucosus in being destitute of scales. t Through the kindness 



* Kroyer in his ' Scandinaviens Fiske' figures a Lycodes perspicil- 

 lum which has a white spot close behind each eye and nine dark 

 bands crossing the body : there are two varieties, which dift'er in the 

 forms of the bands.

 most essential particulars that he notices : Blennius polaris, iuiberltis,
