DISCUSSION OF SPECIES AND THEIR DISTRIBUTION.

ridges; 7 bucklers along the base of the dorsal, the fifth aud sixth largest; 2 on the median 

 line in front of the veutrals, the second largest; one median ijlate, aud G pairs between 

 ventrals and anal, and 4 along the base of the anal. Top of the head with I'oughish 

 ridges, but without spines ; a spine at the base of each dentary bone ; the broad maxillaries 

 each with a supplemental bone; teeth nearly obsolete. Eye large, nuich nearer the gill 

 opening than the tip of the snout. Gill-rakers short. Caudal peduncle very slender, the 

 caudal fin short and rounded; ]>ectorals very short; ventrals large, the rays i, G, the first 

 soft ray closely appressed to the spine; anal spines sliort and stout, the soft rays, like 

 those of the dorsal, low; dorsal spines filamentous. D. IX, 2G; A. Ill, 24. Pelagic; one 

 specimen taken at Provincetown, Mass. (Description from the original type,by Jordan.) 



ZENOPSIS OCELLATUS. 



Zenopsis conchifer, (Lowe), is closely allied to this species and is a pelagic form. Fo 

 evidence has as yet been found of its occurrence below the surface. 



CYTTUS, Gunther. 

 Cyttus, GtiNTHER, Cat. Fish. Brit. Mns., ii, 18G0, p. 396. 



Body compressed and elev.tted, covered with very small scales; month protractile. 

 Two contiguous dorsal fins, the first with eight or nine spines, tlic anal with two short 

 spines. No bony i^lates along the base of the dorsal and anal fins. Ventral fins composed 

 of one spine aud six or eight soft rays. Minute teeth in the jaws and on the vomer, none 

 on the palatine bones. Branchiostegals, eight. 



The tyi)e is Ct/ttvs oustraUs {Gupros anstralis, Eichardson), ti-om Australian seas. C. 

 ahbreviatus, Hector (Giinther, Challenger Keport, xxii, p. 22, PI. X, fig. B), was obtained 

 in 400 fathoms some 200 miles off Cape Farewell, New Zealand. C. hololrpis, described 

 below, was obtained in 220 flithoms. It is fair to assume then, since two out of three 

 of the known species are found in deep waters, that C. amtraUs also descends to the 

 depths.

The gi-eatest depth of the body, which is at the ventral origin, is two-fifths of the total 

 without caudal. The length of the head is three-eighths of the standard length. The eye 

 is very large, equal to two-ninths of the length without caudal, and more than one half tlie 

 length of the head. The width of the iutenu-bital space, millimeters, is two-fifths of tlie 

 length of the head. The intermaxillary is protractile aud when drawn out a deei) horseshoe-
