NOTOSCOPELUS RESPLENDENS (Richardso.nj. (Figure iU.) 

 Lampanyrtus resplendenn, Richardson, Voy. Ereb. and Terr., Ichth., 42, pi. 27, figs. 10-18.— CuviER and 



Valenciennes, xxii, 452. 

 Scopelus resplendens, Gunther, Cat. Fish. Brit. Mas., v, 1804, 415. 

 Scopelus crocodilus, Cuvier and Valenciennes, xxii, 447 (not Risso). 



Height of body 5 times iu total Iciigtli (without eaudal); length of head 3i or 3f ; 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 couical, with jaws equal in 

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

 scarcely dilated behind. Origin of dorsal midway betweeu the e.xtremity of snout and 

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

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

 lateral line rather larger than others. 



Mediolaterals 3, in 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; D. 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 

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



NOTOSCOPELUS QUERCINUS, Goode and Bean, n. s. (I'iguiv 97.) 



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

 nearly 4 times iu length of head (3.i 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 preopercxdum. Length of ujiper jaw al)out four-fifths that of head. Origin of dorsal 

 much nearer tip of snout than root of caudal, being over the twelfth scale of tlie 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 fi-om end of dorsal equaling 

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



Mediolaterals 3, iu 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 fiap of the oi)erculum 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. 



The Alhutrosn obtained a specimen (No. 43790, U. S. N. M.) from station 2731, iu 36° 

 45' N. lat., 74'5 28' W. Ion., at a depth of 781 fathoms, and also a young specimen (No. 

 43791, U. S. N. M.), at the surface by electric light, at station 2528, in 41° 47' N. lat., 67° 

 37' 30" W. Ion., at a depth of 677 fatiioms. 



This species is very closely allied to Scojyelus elongafiis, as figured by Raffaele (Mitt. Zool. 

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