The Ichthyological Results of the Expeditions 



of the „Ingolf". 



By Chr. LCitken. 



THE oceanic ichthyological earnings of the 2 expeditions of the Ingolf» in 1S95 and 1896 are in 

 so far rather considerable as they comprise c. 29 genera and c. 44 species; but they do not com- 

 prise many types which are new, viz. not known or described in our own days or in earlier times. 

 But thev number several forms which were not formerly known at our museum or from the northern 

 seas more accessible to us, and there are species among them which have been known hitherto in 

 few specimens only and thus from a very limited study-material. The knowledge of the distribution 

 of several types is therefore now extended, as also the knowledge of their occurrence over an area 

 hitherto little examined, and an addition somewhat considerable is thence procured to the earnings of 

 the earlier expeditions of the Challenger , le Talisman , le Travailleur , the Blake , the Alba- 

 tross , the Voringen , the Knight Errant , PHirondelle and the Princesse Alice etc. 



It was so far a disappointment that the expedition did not forward us several rather well 

 known arctic or abyssal types that might have been expected, f. i. apodal Lophioidei, arctic picked 

 dog-fishes, Aphanopus etc. The impossibility of using the weel of the prince of Monaco in seas of 

 a northern and troublesome character and the difficulties, to say the least, of using angles must wear 

 the blame for the deficiencies in this respect. The types, which will be specially mentioned in the 

 following sheets and partly figured in the accompanying plates, are chiefly Cottoidei (in the wider, 

 older sense of the word), the Lycodes, Liparides and allied types (Paraliparis), Rhodichthys^ Macrums 

 and other deep-sea Gadoids and deep-sea fishes [Alepocephalus, Antimora), deeip~sea.-Murcenoids, A 

 cant hi ni and certain Raja - species. That the account of Scopelini is rather scarce is due to the diffi- 

 culties of capturing those fragile fishes. That the results as here exposed may be found somewhat 

 uncertain in several cases — in certain difficult genera — owing in part to my personal defects, I shall 

 not deny, but I hope that the special difficulties of those cases will be my excuse. The number of 

 the plates I have reduced to the most necessary. I have specially made use of the colored sketches 

 made on board of the Ingolf <>}' animals still living or freshly caught, which made it possible t<> 

 produce some colored figures. 



Mr. Adolph Jensen has been kind enough to assist me with the revision of the manuscript 

 and in other ways; I owe t<> him several important corrections and emendations and bestow on him 

 my best thanks for his aid.
