72 DEEP-SEA FISHES OK THE ATLANTIC BASIN. 



Two specimens (No. 23369, U. S. X. M. ; No. 272, Gloucester Donations), 00 and G3 milli- 

 inetcrs, were taken on the (Irand Bank by the schooner Lizzie. Individual, !tO millimeters 

 in length, is Xo. l.'JTST, U. S. X. M. ; Xo. 284, of the Gloucester Donations. xVnother (Xo. 

 2375G, U. S. N. M.; Xo. 58S, Gloucester Donations), 95 millimeters in length, washed aboard 

 the schooner Conductor on the Grand Bank. A specimen (Xo. 934, Gloucester Donations), 

 100 millimeters in length, was taken by schooner Marguerite, off Banquero. Still another 

 specimen (No. 24640, U. S. N. M.; No. 007, Gloucester Donations), 90 millimeters in length, 

 washed aboard the schooner Gatherer on the Grand Bank. An individual (No. -43781, U. S. N. 

 M. • No. 283, Gloucester Donations), 87 millimeters in length, with caudal somewhat imperfect, 

 ■was obtained January 30, 1879, in about 44° 30' N. lat., 54° 3.")' W. Ion. It washed aboard 

 in rough weather. One (Xo. 608, Gloucester Donations), 83 millimeters in length, washed 

 aboard the schooner Plymouth Rock on the Grand Bank during a storm. Another (No. 

 24648, IT. S. N. M. ; No. 604, Gloucester Donations), also washed aboard the schooner Mary 

 F. Ckisholm on southern edge of the Grand Bank. A specimen (No. 43783, U. S. N. M. ; Xo. 

 573, Gh)ucester Donations), three specimens (Xo. 43788, U. S. X. M.; No. 867, Gloucester 

 Donations), three specimens (Xo. 29982, U. S. X. M.), and specimens (Xo. 43784, IT. S. N 

 M. ; No. 281, Gloucester Donations) were also obtained by the Gloucester lishernum. 



The Fish Hawk secured chree specimens (No. 28999, U. S. N. M.) from station 1044, in 

 38° 37' N. lat., 73° 12' W. Ion., at a depth of 224 fathoms; and the Albatross captured 

 several specimens (No. 43786, U. S. N. M.) at the surface at station 2549, in 39° 51' 30" N. 

 lat., 70° 17' W. Ion., a depth of 571 fathoms, and specimens (Xo. 35696, F. S. X. M.) from 

 station 2262, in 39^ 54' 45" X. lat., 69^ 29' 45" W. Ion., at a depth of 250 fathoms. 



This species is evidently the M. punctatum of Ilaftnesc^uc, as well as of Bonaparte. 

 We have identified it with a number of specimens labeled '■'■ t<copelus Caninianus,''^ obtained 

 at Messina and iiresentcd by the Royal Zocilogical Museum at Florence (Xo. 40057, T^. S. 

 N. M.), and also with the figure and descrii)tion of Bonaparte and Rafinesque. Though 

 Rafinesque's figure does not fully agree with the description, which is manifestly careless, 

 it has the posterolateral photophores in front of the dorsal, as in all our specimens. 



We are unable to determine exactly what form is that discussed by Liitken (p. 251), 

 under the name Seopelus Caninianus, Cocco, for it has the posterolateral photophore miich 

 farther back in relation to the termination of the second dorsal and anal fin than has our 

 M. puiictntnm, and is in this respect more (;losely allied to Liitken's Scopehis affinis (p. 252).

Scopehis {(ffiiiis, LiiTKEN, Sj)oli.-i Atlautica, ii, 1892; 32, Fig. 10. 



A species of Myctophum closely resembling M.punctntum, l)ut having the posterolateral 

 photophoie farther back, under the soft dorsal and not far in advance of the vertical from 

 the last I'ay of the anal, over which occurs the break in the series of superanal photophores, 

 the number of which is 7-10-1-4-6. i;adial formula:— (?): L. lat. 37. 



Liitken examined a considerable number of specimens of this species, presumably all 

 taken at the surface, between 38° 40' X. lat., 63° W, Ion., and 39° 54' S. lat., 41° 30' E. Ion. 



MYCTOPHUM OPALINUM, Goode and Bean, n. s. (Figure 81.) 



Height of body contained 4;f times in total (without (;audal); head 4|. Least height of 

 tail is two-fifths of height of body. Snout very short, declivous, with a well-developed 

 median keel, its length about one-third of diameter of eye. Eye large, about 2| in the head- 

 Intermaxillary reaches nearly to angle of preoperculum and is broadly expanded at its 

 extremity and ])artly concealed by the large scales of the cheek. Space between eye and 

 hinder edge of preoperculum only one-half diameter of eye. Origin of dorsal much nearer 

 to tip of snout than to root of caudal, midway between snout and adipose fin, over eleventh 

 scale of lateral line and very slightly behind vertical through origin of ventral. Length of
