of which he gives figures of four interesting species, a new Sylvia 

 nearly allied to S. mexicana, Fringilla leucophrys, Numenius hudsoni- 

 cus, Lath., 1. N. borealis, Wilson, and Anas Barrowii of Richard- 

 son. Then follows a list of the Greenland Fish, accompanied with 

 numerous observations, and with the description of two new genera, 

 which he thus characterizes : 



Lycodes. 

 Corpus elongatum, antice incrassatum, rostro obtuse conico, trunco com- 

 pressor cauda ensiformi. Squamce corporis rotundse, minutae, tenuissi- 

 mae, cuti immersae. Os dentibus validis, intermaxillaribus, mandibu- 

 laribus, vomerinis et palatinis armatum ; rictus mediocris. Membrana 

 branchiostega sexradiata utrinque jugulo connata, apertura branchiali 

 angusta postica. Pinnce ventrales obsoletae brevissimae latiusculae jugu- 

 lares. Pinna dorsalis et pinna analis longissimae, apicem caudae cir- 

 cumdantes ; radiis articulatis divisis. Vesica natatoria nulla. 

 Inter Zoareceum et Anarrhicam genus medium. 



1 . Lycodes Vahlii. Corpore fasciato, capite postice parum depresso ; pin- 

 nis, dorsali et anali, squamis minutissimis adspersis, ilia radiis 117, hac ra- 

 diis 93 ; ano ante medium gastrasum sito. (Tab. V.) 



Pustulated Blenny, Pennant, Artie. Zool. — Blennius polaris, Sabine. 



2. Lycodes retmdatus, corpore reticulato ; capite postice compressiusculo; 

 pinnis, dorsali analique, nudis, ilia radiis 95, hac radiis 75 ; ano fere in 

 gastraeo medio sito. (Tab. VI.) 



3. Lycodes seminudus, corpore concolore, ab apice oris usque ad angulum 

 anteriorem pinnae analis nudo ; capite postice compressiusculo ; pinnis dor- 

 sali analique nudis, ilia radiis 91, hac 71 ; ano pone medium gastraeum sito. 



Bythites. 



Corpus breve compression antice incrassatum, ore fere truncato, cauda 

 ensiformi. Squamce corporis rotunda? minutae imbricatas. IAnea late- 

 ralis tubulis exsertis cutaneis compacta, interrupta. Os dentibus acu- 

 tis intermaxillaribus, mandibularibus, vomerinis et palatinis armatum ; 

 rictus mediocris. Membrana brancliiostega utriusque aperturae invicem 

 connata sub isthmolibere suspensa; radiis octoj apertura ampla infero- 

 postica. Pinnce ventrales obsoletag uniradiatas filiformes longiusculae ju- 

 gulares. Pinnce, dorsalis et analis, longae, apicem caudae circumdantes ; 

 radiis articulatis divisis. Membrum conicum crassum pone anum hori- 

 zontaliter porrectum, apice triphyllo papilligero. Vesica natatoria ca- 

 nali pneumatico nullo.
