THE FIvSHEvS OF THE «INGOLF. EXPEDITIONS. 



reckoned from the anus is three fourths of the total length. The jaws are moderately elongated, the 

 length of the upper jaw measured from tlie anterior margin of the eye is contained twice and a half in 

 the whole length of the head. The month reaches backwards xnider the eyes, which are not absolutely 

 small. The branchial openings are very wide, obliquely placed slits in the median ventral line, almost 

 continuous. The jaws are armed with fine teeth, and the vomer wears a long series of denselv placed 

 pointed teeth. The very small pectorals are placed at the upper end of the branchial slit. The 

 dorsal fin is represented by a series of very delicate and short rays beginning somewhat behind the 

 anus, also the rays of the anal fin are very feeble, but perhajDS somewhat longer. The soft blue-black 

 skin is more or less lacerated in all the 3 specimens btit partially preserved. The measures are the 

 following: 



Total length 680""" 570""™ 510'"'^ 



The length of the head to the branchial slit 100 - 93 - 85 - 



The length of the beak to the corners of the mouth ... 42 - 37 - 35 - 

 Trunk and head from the point of the snout to the anus 170 - 135 - 123 - 

 Length of the tail from the anus 510 - 435 - 387 - 



The Scrrivoiner Beanii was known hitherto from a single sj^ecimen caught by the Albatross 

 at 41° 40' 30" Lat. North, 65" 28' 30" Long. W. and at 855 fathoms depth. It is described by Gill and 

 Ryder in 1883 (Proc. U. vS. Nat. Mus. VI, p. 260) together with a related type Spiiu'voiiicr Goodci, also 

 taken by the •; Albatross ;• in the northern Atlantic likewise in a single specimen. Both the generic 

 names are derived from the armature of the vomer with large teeth. Goode and Bean have in the 

 «Oceanic Ichthyology; p. 155 distinguished them as a separate group of nemichth^id murfenoids: 

 SpinwovteridaL\ to which is further referred the A^ciiiichthys (Serripes) Richardi \'aill., captured b\- the 

 «Talisman» at the Azores on 2995 fathoms and originally con.sidered by Vaillant ( v Exp. scientifiqnes 

 Travailleur et Talisman , p. 93, pi. VH, fig. i — la) as identic with Giinthers: Nciiiichfliys iiifaiis 

 (Chall. Rep. vol. XXII, p. 264, pi. 63), but in the «Appendice> (p. 385) to the said work established as a 

 separate species.

Besides the A. rostra fiis already known to Risso from the Mediterranean and from adjoining 

 parts of the Atlantic as far as the Azores, the Canarian and Capoverdian islands — for which species 

 besides the older figures by Risso and Valenciennes I may refer to Vaillant s Expeditions 

 scientifiqnes :> (pi. XI and XII) and to «Oceanic Ichthyologys (p. 36, fig. 41) — some other atlantic 

 species have been described especially by American ichthyologists: A. Agassizii G. B., A. prodiicfiis G\\\ 

 A. Bairdii G. B., Conocara Mc. Doiialdi G. B. and A. (C.) umcroptcrus \^aill., for which species I ma\- 

 refer to sOceanic Ichthyology p. 37-39, fig- 45, 46, 47, 48 og 43. A further addition is A. Giardi
