NOTOSCOPELUS RESPLEXDENS (BlCHABDSON). (Figure94.) 

 Lampanyctua resplendent, Richardson, Voy. Ereb. and Terr., Ichth., 12, pi. 27, hgs. 16-18. — Cuvikr and 



Valenciennes, xxii. 152. 

 Scopelns retplendens, Gunther, Cat. Fish. Brit. Mus., v, 1864, 415. 

 Scupelus crocodilm, Cuviee and Valenciennes, xxii, 147 (not Risso). 



Height of body 5 times iu total length (without caudal); length of head 3J or 3§; least 

 depth of tail more than one half height of body. Eye moderate; distance between posterior 

 margin of orbit and preopercular edge less than diameter of eye. Posterior margin of pre- 

 operculum descending obliquely backwards. Snout obtusely conical, with jaws equal in 

 front. Cleft of mouth nearly horizontal. Maxillary reaches to angle of preoperculuni and 

 scarcely dilated behind. Origin of dorsal midway between the extremity of snout and 

 adipose tin, and above root of ventral; its last ray above middle of anal. Pectoral fin 

 shorter than ventral, and not extending beyond its root. Scales perfectly smooth, those of 

 lateral line rather larger than others. 



Mediolaterals 3, iu curved subvertical line; posterolaterals 2, horizontally side by side, 

 the posterior one in advance of the soft dorsal. Precaudals 2 + 1, the last slightly below 

 the end of the lateral line. Radial formula: B. 8; 1). 21-24; A. 18; V. 8; scales 3 | 38 | 5. 



This species was described from the Gulf of Guinea. It is very desirable that the 

 Bohuslan species should be examined, as well as those in the museum at Milan. 



NOTOSCOPELUS QUERCIXI's, Goode and Bean, n. s. (Figure 97.) 



Height of body 5g in total length; length of the head 3§-4. Eye moderate, contained 

 nearly 4 times in length of head (3.J in eye). Snout short, about one-half as long as the 

 diameter of the eye. Mouth oblique, and very large, the maxillary extending to angle 

 of preoperculuni. Length of upper jaw about four-fifths that of head. Origiu of dorsal 

 much nearer tip of snout than root of caudal, being over the twelfth scale of the lateral line 

 and immediately above origin of ventral ; length of its base equals that of head, and longest 

 ray two-thirds as long as head, its end over seventh ray of anal. Pectoral short, not 

 reaching to origin of ventral. Anal origin about under twenty-first scale of lateral line; 

 the length of the base equals that of head without snout, and the longest ray is about one- 

 half as long as head. Adipose fin very slender, its distance from end of dorsal equaling 

 one-half length of head. Caudal moderate, deeply forked. 



.Mediolaterals 3, in curved subvertical line; posterolaterals 2, under the soft dorsal : pre 

 caudals 2 + 1, the last below the end of the lateral line. One of the precaudals very high 

 up, between the Hap of the operculum and the lateral line. 



Eadial formula: D. 21-21; A. 19-20; L. lat. 42. 



The species is described from a specimen (No. 43789, U. S. N. M.; No. 822, Gloucester 

 Donations). 125 millimeters in length, taken by one of the Gloucester fishing vessels. 



'I'lie Albatross obtained ■., specimen (No. 43790, U. S. N. M.) from station 2731, in 36° 

 15' N. lat.. 71 28' W. Ion., at a depth of 781 fathoms, and also a young specimen (No. 

 43791, I*. S. N. M.(. ai the surface by electric light, at station 2528, in 41° 47' X. lat,, 67° 

 37' 30" W. Ion., at a depth of 077 fathoms. 



This species is very closely allied to Scopelus elongatus, as figured by Kaffaele (Mitt. Zool. 

 Stat. Naples, IX, 185, pi. vn, fig. 11), and also agrees with a specimen sent (from Nice)
