Appendices pyloricne har manglet lios de af mig aab- 

 nede Individer. 



Finnerne. — iStraaleantallet tandtes lios en Del un- 

 dersøgte Individer at være følgende (i de verticale Finner 

 er indbefattet den halve Caudal) : 



Dorsalen udspriuger i eu Afstand fra Gjællelaagets. 

 bagre Flig. der sonioftest er lig Lindsens Afstand fra Snu- 

 despidsen, ellei' ubetvdeligt mindr^. Dens Afstand fra 

 Snudespidsen indeholdes hos de storre Individer omtrent 3 

 Gange, hos de mindre omtrent S'/a Gange i Totallfengden ; 

 dog er dette Forhold noget varierende. Dens første Straale 

 ligger omtrent lige langt mellem Anus og Øjets Bagrand. 

 Af Bygning er Dorsalen ganske, soni hos de øvrige 'Lyco- 

 der, med" sin største Højde i den forreste Del. og svagt af- 

 tagende bagtil. 



Straalerue. som hos de storre Individer ligge indhyl- 

 lede i en tyk Hud. som ofte gjør dem vanskelige at tælle, 

 ere mellem 93 og 98 i Antal, hvortil kommer Caudalens 

 øvre Halvdel med G Straaler, tilsammen 99 til 104 Straa- 

 ler. De ere alle (ogsaa den første) kløvede til Grunden. 

 men begge Halvhele ere yderst spinkle og tætstaaeude, ved 

 Grunden nleddede. men udåd tint articulerede. og i Spid- 

 serne divergerende. 



Analen. der udspriuger et Stykke bagenfor Anus. er 

 af Bygning som Dorsalen, og tæller mellem 80 og 85 

 (gjennemsnitlig 82) Straaler. som. tilligemed Caudalens nedre 

 Halvdel (der bestaar af 5 Straaler). udgjøre tilsammen 85 

 til 90 Straaler. 



Caudalen danner 2 sammenhængende Straaleknipper, • 

 Dqrsalsidens bestaaende af 6. Ventralsideus af 5 Straaler. 

 der ere san'deles fine og yderst tætstaaeude. og derfor van- 

 skelige at tælle. Dens hele Længde er omtrent lig Læng- 

 den af Yentralerne (eller hos de ældre Individer noget der- 

 over). 



Pectoralerne have 19 — 21. Straaler. oftest 20. af hvilke 

 de øvre ere de la?ngste; hos enkelte Individer er Finnens 

 nederste Del atter noget længere. end den mellemste. 

 saaledes at Randen hos disse bliver svagt concav. De 

 nedre Straaler ere bekhedte med eu tykkere Hud. end de 

 øvrige, og have fri Spidser. Straalerne ere for'holdsvis 

 koi'te. saaledes at Finnen, naar den bøjes fremover, med sin 

 Spidse blot hos de yngste Individer naar frem til Bagran- 

 den af Lindseu. men er hos de større en halv. hos det 

 største (et sandsynligvis fuldt udvoxet Individ) endog en hel 

 Øjendiameter fjernet fra denne. Hos dette sidste opnaar 

 Pectoralen blot Hovedets halve Længde. hos de yngre noget 

 mere, 'end denne. Straalerne ere alle klovede til Roden, 

 og fint articulerede.

The dorsal commences at a distance from the post- 

 erior flap of the opercle generally equal to the distance 

 from the lens to the point of the snout, or a trifie less. 

 Its distance from the snout, in the larger specimens, is to 

 the total lengtli about as 1 to 'å: in the smaller. al)out as 

 1 to 3'/o; this proportion varies however to some extent; 

 Its first ray is about equidistant from the vent and the 

 posterior margin of the eye. The structure of the dorsal 

 as in all species of Lt/codes, the greatest height of tlie 

 fin being in its anterior portion. 



The rays, which in the larger individuals are envel- 

 oped in a thick cutaneous integument, rendering them often 

 difficult to count, number fi'om 93 to 98. to which must 

 be added those in the upper half of the caudal: so that 

 the total number is from 99 to 104. They are all (includ- 

 ing the first) cleft to the base; but both halves are ex- 

 ceedingly slender and close, simple at the base, but in 

 the outer part finely articulated, and diverging at the 

 points. 



The anal, commencing a short distance posterior to 

 the vent, is of the same structure as the dorsal, and 

 furnished witli from 80 to 85 (generally 82) rays, or, 

 including the 5 rays in the lower half of the caudal, 85 

 to 9U. 



The caudal is composed of 2 continuous bunches of 

 rays, that on the dorsal side with 6. that on the ventral 

 side with 5 rays, exceedingly slender and ver}- closely set; 

 therefore difficult to count. The length of this fin about 

 e(|uals that of the veutrals (in the older specimens it ex- 

 ceeds it). 



The pectorals are furnished with from 19 to 21 rays, 

 most irequently with 20. of which the upper ones are the 

 longest ; in some individuals, the inferior portion of the fin 

 is a ti'ifle longer than the middle part, and its margin there- 

 fore slightly concave. The lower rays are enveloped in a 

 thicker skin than the upper, and have free points. The 

 rays are comparatively short, their points reaching forward 

 to the posterior margin of the lens in the youngest spec- 

 imen only, being in the larger exanqjles distant from it 

 one-half of the diameter of the eye, and in the largest in- 

 dividual a whole eye-diameter; in the latter, the pectorals 

 do not attain more than- half the length of the head ; in 

 the younger specimens, the proportion is greater. Rays all 

 cleft to the base, and finely articulated.
