Over Bas'i'mideu Mi' Øjneue staa pan liver Side et 

 Par kegletbrmige Kuiuler, der lige til Spidseu ere klædte 

 at' Hovedhudeu ; af disse er den ydre den raindste (hos det 

 mindre Ex. fra Stat. 862 er den uæsten umærkelig). I 

 omtrent en IJrbitaldiameters Afstand bagenfor disse staa 

 paa hver Side en enkelt Ivnude. der er af Hojde og Form 

 som den største af de forreste. Tilsammen danne disse 4 

 storste Knnder et .Qvadrat. hvis Bredde indeholdes omtr. 

 I'/a Gang i deres Ltengde, og de repræsentere selvfolgelig 

 den samme Anordning af Pandeknuderne, som hos de fleste 

 ovrige. Arter af denne Familie. Endelig tindes et Par 

 stumpere Kunder jiaa hver Side af Hovedet i den Linie, 

 der strækker sig melleni Øjets 

 Rand. 



Øjnene ere forholdsvis smaa. 

 dog er Øjets ydi'e Begra^ndsning 

 Overhuden er heklædt med de samme spidse Bentorne, som 

 ere stroede ud over hele Hovedet, lige ind mod Lindsen. 

 Navnet inicrops er derfor kun forsaavidt betegnende, som 

 næsten hele Iris er skjult under denne farvede og ru Over- 

 hud. Dog maa . Orbitas Lanigde antages at indeholdes over 

 5 Gange i Hovedets Laaigde: Afstanden fra Lindse til 

 Lindse indeholdes omtrent 3'/j- Gange i . Hovedhengden.

 Uuderkjæven rager ganske 



og Interorbitalrummet

 til unjler Midten af Lindsen. 

 ubetydeligt frem foran Overkjæven. 



Næseborene ere 2 Par, hvoraf de nederste ere ror- 

 formigt forlængede. Overkjævens Rand, det forreste Næse- 

 bor, det bagerste Næsebor. og Øjet, ligge fjernede i en 

 indbyrdes Afstand fra hinanden af omtr. en Liudsediameter. 

 Tungen er Særdeles bred og tyk, og fortil fri. 



, Gjællehinderne have 6 Straaler ; de ere ikke sammen- 

 voxede paa Hovedets Underside, saaledes at de danne en 

 tvers over denne lobeude fri old, saaledes som hos alle 

 de øyiige Slægter af vore cottoide . iske (Coitus, Phobefor, 

 Centridennichthys, Icelus, Triglops, etc.^, men ophører 

 ved den nedre Ende af hver Gjællcspalte. Den indbyrdes 

 Afstand melleln Gja^llespalterne paa Hovedets Underside er 

 omtrent lig Hovedets postoi'bitale Del, saaledes forholdsvis 

 betydelig. 



Gjællespalten er forholdsvis vid og strækker sig fra 

 Pectoralens nedre Fæste op til ovenfor Legemets Midtlinie, 

 Operculum er særdeles stort og bredt, og dækker et ikke 

 ubetydeligt Parti af Legemet mellem Gjællespalten og Pec- 

 toralen; den øyre fri Rand af Operculum danner derfor 

 en næsten ret Linie af Længde som eii Øjendiameter. 

 Gjællerne ere af normal Bygning, 



Tienderne ere tilstede i Kjæ verne, og paa Vomer, 

 men mangle paa Palatiubenene, I Over- og Underkjæven 

 danne de flere Rækker; jjaa Vomer sidde de i 2, neppe 

 sannnenhængende Felter, 



Finnerne. Straaleantallef i de forskjellige Finner viste 

 sig at van-e følgende:

Dorsalen, , , , 20 (G + 14); 21 ((3 + 15); 20 (6 + 14). 



Above the posterior margin of the eyes,- on either 

 side, occur a couple of cuneiform protuberances or tuber- 

 cles, enveloped up to the point in the skin of the head'; 

 the exterior is the smaller of the two (in the small 

 exanij)le from Station 362 scarcely obvious). Posterior to 

 these tubercles, on either side, distant about the length of 

 the (U'bital diameter, is an isolated tuberbcle. the same in 

 shape and size as the larger of the two anterior ones. The 

 four largest tubercles form a quadrangle, the breadth being 

 to the length as 1 to U/^; hence the disposition of these 

 protuberances is precisely the same as in most of the other 

 species of Cottidce. On either side of the liead 2 tuber- 

 cles, somewhat more obtuse, occur along the line extending 

 between the eye and the upper margin of the gill-opening. 



Eyes comparatively small, but with large lenses ; the 

 exterior limit of the eye, however, is difticult to determine, 

 tlu' cuticle being studded, nearly to the edge of the lens, with 

 shai']) osseous prickles, similar to those dispersed over the 

 entire surface of the head. Hence the name microps is 

 not otherwise appropriate than from the circumstance of 

 the iris being almost entirely hidden beneath the rough and 

 coloured cuticle. The diameter of the orbit cannot, .how- 

 ever, be much less than one-tifth of the length of the head ; 

 the distance between the lenses is to the length, of the 

 head as 1 to 3^;:..: interorbital space consequently broad. 



Mouth wide, the maxillary extending to the middle 

 ■ of the eye. The lower jaw slightly projecting beyond 

 the upper. 



Nostrils double, each of 'the lower tubular. Distance 

 between 'the margin of upper jaw, the anterior nostril, the 

 posterior nostril, and the eye in each case about equal to 

 the dianu'ter of the lens. Tongue exceedingly broad and 

 thick, the forepart detached, 



Brancheostegous rays 6; the gill membrane not con- 

 tinuous across the isthmus and connecting the gill-openings 

 by a detached cutaneous flap, as is the case in almost all 

 the other genei'a of our Cottoid tishes (Coitus, Phobetor, 

 Centridermichfhys, Icelns, Triglops, etc.^, but attached to 

 the isthmus, and terminating at the lower extremity of each 

 opening. Distance between the lower margin of the gill- 

 openings about equal to the length of the postorbital 

 region of the head, and hence comparatively great. 



The gill-openings are comparatively wide, extending 

 from the base of the pectorals to some distance above the 

 mesi.an line of the body. Operculum very large and broad, 

 covering a considerable portion of the body between the giU- 

 openings and the pectorals; upper free margin of oper- 

 culum, in len.gth about equal to the diameter of the eye, 

 consequently almost •strai.aht. Structure of gills normal. 



Teeth in jaws and on vomer, wanting on i)ie palatine 

 bones. Along the maxillaries they are regularly disposed 

 in several well-detined series ; on the vomer, the arrangement 

 is in two quadrangular divisions, probably continuous.
