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 weel , parth- in the company of Siine^ichelys parasiticus ^ relatively 251 and 

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

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

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

 S. bafhvbius 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- 

 hranchus iufcnialis Gill. (Proc. Un. St. Nat. :\Ius. 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 Synapliobranclius and Histiobrajicluis as different, partly also 

 the species of //. bathybius and H. iiiferiinlis ^ and it would therefore be the most correct thing to 

 retain the later name for the northatlantic type. Further: .S'. brcvidorsalis Gthr. (1. c. p. 255, pi. 63, fig. C) 

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



«Ingolf captured 2 specimens of a Syiiaphobraiichiis (or, according to Goode and Bean, of 

 a Hisfiobraiic/iiis)^ 16 and 1872 inch, long, at the stations 36 and 37 on 61° 50' L,at. North, 56° 21' Long. 

 West and on 60" 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°.4 C. It will be sufficient 

 to state of those Histiobranclii of the «Ingolf t , 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 Synapliobranclius piiiiiatus^ but either to //. bailiybius or to Gill's H. infer- 

 iialis, if tliese 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 I'^.s 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 G/obio-cri/ia-sheWs 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: slower 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) of Scrriiioiuer 

 Beanii Gill & 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
