A single specimen, 220 mm. long, which thougli not in entire 

 agreement with Giinther's description and figure, is so similar 

 that despite the wide range between South America and the 

 present locality, I liesitate to regard it as distinct. It difl:ers 

 from the Challenger figure in having the tail about two-thirds 

 the length of the head longer, and produced into a fine point. 

 The whole body is rather more slender and the anal rays ai'e 

 longer. The fins are dusky, and the outer anterior Jialf of the 

 anal is black. Inallothercharactersitisinagreement withthefigure, 



It may be that the type specimen had the tail imperfect as in 

 one of our specimens of Optonii7-ns denticu/atus (see p. 346) in 

 which case these differences would be of little importance. 



CCELORHYNCHUS INNOTABILIS, sp. 7iOV.

 D. II. 8; P. 18; V. 7. 



Greatest depth of the body 1 1 -5 in the total length. Head 

 including the spine on the snout 5-5 in the same. Snout 2-4 in 

 tlie head, longer than the eye which is almost 3 in the head. 



Snout broad, its terminal half tapering abruptly and tipped 

 with a sharp triangular spine. Orbit elliptical, a little longer 

 than the post-orbital portion of the head, and touching the dorsal 

 profile. Interorbital space 1 "8 in the longitudinal diameter of the 

 eye. Widtli of the moutli at the angle of the gape nearly twice 

 in the width of the head in the same line ; maxillary reaching to 

 below the posterior margin of the eye. Barbel very small, one- 

 fifth the length of the eye. Ridges on the head very pronounced. 

 A median one from the rostral spine to between the first-third of 

 the eyes The supraorbital ridge extends round the posterior 

 edge of the eye before turning oft" in a horizontal line to the upper 

 end of the gill-opening. Tlie inner pair of ridges branch off from 

 the supraorbitals slightly in advance of the middle of the eye, and 

 convei'ge gently, becoming parallel till about the middle of their 

 length, where they again separate a little. The spaces between 

 the ridges, other than on the top of tlie head and the nape, are 

 quite bare and formed of soft, membranous, and translucent skin
