296 DEEP-SEA FISHES OF THE ATLANTIC BASIN. 



CALLIONYMUS, Linnseus. 



Callionymus, Linn.eus, Systcma Natura', ed. x, 1758, I, 249 (type, C. lyrn) ; oii. xil, i, 433. — Gill, Proc. Acad. 

 Nat. Sci. Phila., 1859, 125. 

 Gol)ioids with triangular depressed head, narrow month, protractiU^ npi)er jaw, and gill- 

 opening' rednced to a very narrow foramen on the upper surface of tlic^ head. Eyes mod- 

 erate, looking upwards. Teeth minute, absent from palatines. Angle of preoperculum with 

 a strong spine. A single lateral line. First dorsal composed of a very few flexible spines. 

 Ventrals normal, remote. Branehiostegals G. No air-bladder. Pseudobranchiai present, 

 (iills 4, with a slit behind the fourth. 



'■'■CaUionymuii has been restricted to species with a single lateral line, branchial aper- 

 tures on the sides of tlie nape, and perfect ventral fins. The V. (jornmensis, Blkr., may be 

 regarded as a distinct type (Diplofirammus), distinguished by the double hiteral line. Syn- 

 chiropus and Ductyloptts are excellent genera, and the last has been adopted under the name 

 Yulstis, the change of name having been made on account of the existence of the term Dae- 

 ti/ldjioda, given by Von Meyer to a group of reptiles, as I have been kindly informed by the 

 author of the change. Such extreme views would necessitate very numerous changes in 

 the nomenclature, and are not recognized by naturalists generally." (Gill.) 



CALLIONYMUS LYRA, Linnjsus. 



CaUionymus lyra, Linn^US, Systema Naturae, ed. x, 1758, i, 249; ed. xii, 17G6, ii, 433. — Vaillaxt, Exp. Sci. 

 Travailleiir et Talisman, 349. 



This well known European form, found along the entire coast of Europe from the Ger- 

 man Ocean to the Mediterranean, was obtained by the French expedition in the Gulf of 

 Gascony in 411 meters, off Spain and Portugal in 1)9 to 240 meters, oft' Morocco in 112 

 meters, and near the Canaries in 90 meters. 



In addition to the three Atlantic forms named below, the Challenger took C. laianvs, 

 Giinther, in 140 fathoms oft' the Kai Islands (station 192), C. calauroponms, Eichardson, from 

 115 fathoms, near the Philippines (station 204 E). 



The Investigator took C carebares, Alcock (Ann. and Mag. Nat. Hist., 1889, ii, 209, pi. 

 VIII, fig. 8), in the Bay of Bengal (station 96), 98 to 102 fathoms, about 70 specimens. 



CALLIONYMUS PHAETON, Gunther. 



CaUionymus fextivus, BONAPARTE, Fauna Italica, Pesci, Fasc. with figures of male and female (not C. fcstivus, 



Pailas). 

 CaUioiiy III us phaeton, GiiNTHER, Cat. Fish. Brit. Mus., ni, 18G1, 147.— Vaillant, Exp. Sci. Travailleur ut 



Talisman, 349. 



A. Callionymus having the preopercular spine bicuspid and the last dorsal and two 

 middle caudal rays filamentous in the male. 



Eadial formula: D. IV, 9; A. 8; C. 10. 



Color; reddish, variegated with green. 



This form, not generally recognized by the Italian ichthyologists, is supposed to occur' 

 in the Mediterranean, where Bonaparte obtained the specimen figured by him. Vaillant 

 had specimens from off the Azores, taken in 5G0 meters by the French Expedition (station 

 CXXIII). 



CALLIONYMUS HIMANTOPHORUS, Goode and Bean, n. s. (Figures 268, 268, A. B.) 



The body is slender, moderately elongate, the fins are all well developed, the tail taper- 

 ing and with some of its rays produced into a filament. The greatest depth is at tlie head 

 and the anterior portion of the trunk. The depth of the head equals the length of its post- 

 orbital portion and, also, the greatest depth of the body. The caudal peduncle is very slen- 

 der, the least height of the tail being scarcely more than one-fonrth the greatest height of 

 the body. The profile descends very rapidly at the snout. The mouth is small and the
