366 DEEP-SEA FISHES OF THE ATLANTIC BASIN. 



PHYSICULUS DALWIGKII, Kaup. 



Phi/sieiihis Dalwigkii, Kadp, loo, cit. — Gunther, Cat. Fish. Brit. Mus., iv, 348 (full description) ; Chal- 

 lenger Koport, XXII, 1887, 88. — Vaillant, Exp. Sci., Travailleur ot Talisman, 1888, 290, pi. xxv, tigs. 3-3c. 



" Eleven series of scales between the anterior dorsal and the lateral line. Axil of the 

 pectoral black. D. 7/67: A. 69: V, 5." {Glint her.) 



Giiuther has studied 3 specimens fi'om Madeira, the largest 10 inches long, and notes 

 that all have an exceedingly narrow base to the ventral fin. 



The species is only known from Madeira and from off Soudan, where the Talisman ob- 

 tained it at two stations, Lxxi, 782 meters, and Lxxi, 640 meters. 



PHYSICULUS KAUPI, Poey. (Figure 318.)

"This species," writes Giinther, "has constantly (as far as is shown by our specimens) 

 a broader base to the ventral tins than Phi/siculus dahcijikii, and they are formed of 7 rays, of 

 which the longest may or may not reach the anal tin. The tin rays vary within propt)rtiou- 

 ate limits; they are: D. !)-10 | CO-GO; A. 60-70. There are 13 series of scales between the 

 anterior dorsal and the lateral line. The peduncle of the tail is shorter and less slender than 

 in the Madeiran form, but otherwise the two species are so similar as to scarcely deserve 

 .specitic separation." 



Poey obtained a specimen at Cuba, and Melliss two at St. Helena. These are pro- 

 nounced by Giinther to differ in no respect from five exami)les found by the Challenger off 

 luosima in 3io fathoms, and 11 to 16 inches long. 



PHYSICULUS PEREGEINUS, GiJNTiiER. 



Pscudo2}hycis pcrcgrinus, GiJnther, Proc. Zool. See. London, 1871, 669. 

 PhysicHlus pcregrinus, GiJNTHER, Challenger Report, xxii, 1887, 88. 



The height of the body is less than the length of tlie head, which is two-ninths of thc! 

 total (without caudal). Vent at only a short distance behind the base of the pectoral ; tail 

 tapering into a very narrow band, the extremity of which is surrounded by the caudal tin ; 

 however, the vertical tins I'cmain separate fiom one another. Head rather broader than 

 deep, its greatest width being two-thirds of its length, luterorbital space concave, its width 

 being less than the diameter of the eye, which is one-fourth of the length of the head, and 

 equals that of the snout. Snout broad, obtuse, rounded, with the upper jaw overlapping 

 the lower; the maxillary extends to below the middle of the eye. Barbel shorter than the 

 eye. Vertical tins of moderate depth, with very fine tin-rays; the first dorsal commences 

 opposite to the base of the pectoral. Pectoral as long as the head without snout. The 

 ventral filament is jugular, extending beyond the origin of the anal, and composed of one 

 longer and two shorter rays. Scales minute and deciduous. 



Eadial formula: D. 7+63 (ca.); A. 66 (ca.); V. 3. 



Color reddish olive (in spirits), abdomen black. 



The British Museum has several examples of this species from Manado, one of which 

 measiu'es 5 inches in length. 



Another species, P. jialmatus, Kliinzinger, is from Port Philip, llobson Bay — probably 

 not a deep-sea form. 



PHYSICULUS FULVUS, Bean. (Figure 319.) 



Physiculnf> fiilru.t, Bean, Proc. U. S. Nat. Mus., 1881, vii, 210. 



A PhysiculuH with head broad and depressed, with a short snout; the length of the 

 liead contained in the total length to the caudal base nearly 4 times. The height of the 

 body is about eiiualto the length of the head without the snout, and is contained Ij times 

 in the total length without caudal. The eye is about two-sevenths as long as the head.
