difference, and could furnish no new information about it), 

 and Giintlier entirely omits it in his ' Catalogue of Fishes,' I 

 have thought that I ought not to miss this opportunity of 

 again calling attention to it. 



The circumstance that for our knowledge of all these three 

 remarkable Greenlandic Lophioids we are indebted to one man, 

 Carl Holboll, deserves to be noticed as an indication of what can 

 be effected in this way by indefatigable attention and intelli- 

 gent zeal, and also of what may be expected from the future, 

 in proportion as interest in and knowledge of nature spreads 

 from the cultivators of science to a greater public. 



Our new genus and species may be characterized as follows, 

 in accordance with what has been stated in detail in the pre- 

 ceding pages : —

Genus et species nova e familia Lophioideorum (Halibatrachorum), 

 nee non e tribu Lophioideorum apodum nudorum. Corpus breve, 

 crassum, mediocriter compressum. Caput maximum, tetragonum, 

 fronte declivi, profunde excavato ; rictus oris mediocris, horizon- 

 talis ; oculi minuti, absconditi ; dentes mediocres, graciles, elon- 

 gati, conici, subincurvi, mobiles in maxillis, in vomere et in pha- 

 rynge supra ; iu palate nulli. Apertura branchiahs sat magna, 

 infra insertionem primarum pectoralium ; pseudobranchiae oper- 

 culares nuUse ; arcus branchiahs primus branchiis destitutus ; 

 branchiorum paria 2|,cute arcum branchialem quartum cum osse 

 hypopharyngeah conjungente ; radii branchiostegi utrinque sex. 

 Pinnae ventrales nullae (pectorales ignotae). Radius frontahs cum 

 osse interspinali horizontah subcutaneo articulatus, hand procul 

 ab apice rostri insertus, sinum frontalem longitudine haud supe- 

 rans, clavaeformis ; caput clavae compressum, tentacula plura mi- 

 nuta gerens ; radius dorsalis (secundus) summo dorso impositus, 

 conicus, depressus, flaccidus, frontalem longitudine superat. 

 Pinna dorsahs vera et analis breves, caudah approximatae, sed 

 distinctae ; caudalis mediocris, haud elongata. Pinnarum formula 

 radiorum : D. 1 + 1 + 6, P.?, V. 0, A. 4, C. 8 ; radii moUes, car- 

 tilaginei, haud articulati, caudales mediani quartuor soli fissi. 

 Squamae nullae ; cutis nuda, molhs, nigra totum corpus obtegit. 

 Vesica natatoria et appendices pyloricae nuUae ; ossa sceleti mollia, 

 semispongiosa, ut in piscibus affinibus, spinis binis frontalibus et 

 mandibularibus exceptis nulhbi in tubercula vel spinas prodeuntia. 



(see Giinther in Ann. & Mag. Nat. Hist. 1861, p. 190, and Steenstrup in 

 ' Videnskabelige Meddelelser fra den naturhistoriske Forening,' 1863, 

 p. 208). I refer to this only in order that this note may not produce the 

 notion that this family of fishes is more strongly represented in the 

 northern seas than it really seems to be.
