 divider var det ene (hvis Totallængde var 265""") en ung 

 Han. med endnu ikke 1'uldt udviklede Testes, det noget 

 større Individ (Totallængde 295""") en Hun. med fuldmodne 

 Æg i det eneste Ovarium. Disse Æg vare forholdsvis 

 store, neppe over 300 i Antal. alle jevnt udviklede; desu- 

 den fandtes et mindre Antal. der tilsyneladende ikke vikle

 Dele af Ovariet med (ufuldbaarne) Æg. Dette viser, at 

 Hunnen saaledes kan opnaa en lignende betydelig Størrelse, 

 som Hannen. Af de øvrige vare de 2 velbevarede Indi- 

 vider Hanner, med udviklede Testes. Den venstre af disse 

 var saa kort, at den næsten kan kaldes rudimentær (14 — 

 17'"'"). den højre lang (70"™).

 hones are furnished on each side with '•• — 11 teeth in a

 occurs on the vomer. 



Young individuals have somewhat fewer teeth, and 

 the full number of the anterior series is attained gradually. 



As in all the I/yco&es, the jaws are protected by a 

 thick adipous skin, depending from the mandible in the 

 form of an oval Lappet.

For comparison are subjoined a few proportions 

 deduced from measurements of the 5 large Finmark spec- 

 imens, 2 dried, and 1 a skeleton. 



Ovaries and testes single. Of the two largest in- 

 dividuals obtained on the Expedition, one (total length 

 265 """) was a young male, with the testes not fully devel- 

 oped, the other, of somewhat larger size (total length 295"""), 

 a female, with mature ova in the single ovary. These 

 ova. hardly more than 300 in number, were comparatively 

 large, all of them uniformly developed, exclusive of which 

 was a smaller number that in all probability would not 

 have arrived at maturity. The ovary was single. 



t If the large specimens from Finmark, one. which had 

 been dried, was a female, portions of the ovary, with (im- 

 mature) ova. being still attached to the abdomen. This 

 shows that females can attain as large a size as males; of 

 the remaining examples, the 2 well preserved specimens 

 were males, with well developed testes. That on the left 

 side is so short as to be almost rudimentary (14 — 17"""). 

 that on the right is long (70""»). 



No pyloric appendages.
