THE FISHES OF THE INGOLF EXPEDITIONS. 



Africa, from the Azores and from the Canarian and Capoverdian islands and from depths between 

 405 og 3200 Metres. Also the prince of Monaco obtained it at the Azores in great numbers, in 

 several draughts of the wee] , partly in the company of Simenchelys parasiticus, relatively 251 and 

 328 specimens. Compare: Collett's Resultats des campagnes scientifiqnes , Poissons p. 154. The 

 S. pinnatus is figured by Giinther (Report on deep-sea fishes pi. 62, fig. A) and by Vaillant 

 ( Expeditions scientifiqnes p. 88, pi. 6, fig. 2). Other species of the same genus are figured and described: 

 S.bathybius Gthr. (south of Japan, in the northern part of the Pacific and between Cape and Kerguelen, 

 Report on deep-sea fishes p. 254, pi. 62, fig. B), at 1375 — 2050 fathoms, perhaps identical with Histio- 

 branchus in/ernalis Gill. (Proc. Un. St. Xat. AIus. VI, 1884, p. 255), The Atlantic: 38 30' 30" Lat. North, 

 69/ 08' 25" Long. West, depth 1731 fathoms. Compare also the Oceanic Ichthyology p. 145, fig. 165. 

 The authors of this work take the genera Synaphobranchus and ffistiobranchus as different, partly also 

 the species of H. bathybius and //. in/ernalis, and it would therefore be the most correct thing to 

 retain the later name for the northatlantic type. Further: A', brevidorsalis Gthr. (I.e. p. 255, pi. 63, fig. C) 

 from North of New Guinea and South of Japan (345—1070 fathoms). 



Ingolf captured 2 specimens of a Synaphobranchus (or, according to Go ode and Bean, of 

 a Histiobranchus), 16 and 18 '\ inch, long, at the stations 36 and 37 on 61 50' Lat. North, 56 21' Long. 

 West and on 6o : 17' Lat. North, 54 05' Long. W., depth 1435 and 1715 fathoms where the bottom was a 

 grayish or light chocolate-coloured mud and the bottom-temperature 1.5 or i : .-iC It will be sufficient 

 to state of those Histiobranchi of the Ingolf , that the small pectorals (of the length of the snout) 

 the position of the anus and the fact that the dorsal fin reaches almost to the head, make it evident 

 that they do not belong to Synaphobranchus pinnatus, but either to //. bathybius or t<> (rill's H. infer- 

 nalis, if these are not synonyms. 



The geografical distribution of the same species will at the same time be elucidated as far as 

 it is known at present. 



Nemichthys (Serrivomer) Beanii Gill & Ryder. 



Of this species Ingolf captured on the Stations 12 and 20, at 64' 38' Lat. North, 32 37' Long. 

 West, and on 58° 20' Lat. North, 40" 48' Long. W., in the Denmark Strait and S. S. E. of Cape Farewell, 

 at a depth of 1040 and 1695 fathoms, on a bottom of soft mud with pebbles and a bottom-temperature 

 of o°.3 and 1 .5 C. two not fully well preserved specimens of the said deep-sea-eel-genus. A third some- 

 what better was obtained at Station 45: 61 32' Lat. N. and 9' 43' Long. W., West of the Faroe Islands 

 on a depth of 643 fathoms, light gray muddy bottom with Globigerina-shells and a bottom-temperature 

 of 4°.i7 C. It is a rather large specimen, 26 inches long; it is noted in the zoological Journal of the 

 expedition in the following manner: lower side of the head quite black, the sides of the trunk and 

 back bronzeously gilt with numerous fine black points . 



Goode and Bean have in the Oceanic Ichthyology given a figure (fig. 175) <>t - s ' 

 Beanii (till ec Ryder which agrees well with the 3 specimens at hand. The shape is much elongated, 

 the length of the head from the point of the beak to the branchial fissure being contained 6 7 times 

 in the total length, further on somewhat compressed and tapering to a long pointed tail, whose length
