 CijUopsis rvseiis, GiLL, loc. cil. 



A Cyttopsis resembling in general appearance Zeusfaber. Height of body one-lialf its 

 length; it.s thickness one (>ightli of the same; length of head two-fifths of length of body. 

 Snont more than half as long as the head, though the maxillary, on account of its nearly 

 vertical position, reaches scarcely to the vertical from the anterior margin of the orbit. 

 Teeth small, in villiform bands on the intermaxillaries, mandible, and vomer. Eye very 

 large, its diameter one third the length of the head; the upper orbital margin provided 

 with a series of saw-like teeth, pointed forward, nearly 30 in number, the five or six most 

 anterior more developed than the others, which can only be vseen with the lens; inter- 

 orbital space .sliglitly concave, striated. Gill opening wide. Vent slightly postmedian. 

 Scales present only in the lateral line and its immediate neighborhood. Three or four bony 

 plates between the ventrals and the vent, the anterior ones armed with very strong spines, 

 pointing backward. At the base of the dorsal and anal fins a series of little nodules, coiTe- 

 sponding to the interspinous spaces. 



Dorsal occupying a large part of the length of the back, its spines very robust; the 

 third, the strongest, is in length equal to one third the height of the body; the first eight 

 or ten soft rays increase in size, the first being the lowest; they are farther apart than 

 those which follow them and are united by a membrane only at their base. Anal very 

 similar to the soft portion of the dorsal; the first spine stout and immovable. The caudal 

 peduncle is widened at its extremity and tlie caudal is abruptly truncate. Pectorals moder- 

 ate, obtuse, composed of 13 rays. Ventrals remarkably long, inserted nearly in the verti- 

 cal from the insertion of the pectorals, and extending behind the anal spine; the two 

 branches which form each ray are very distinct, even from the base, as in Trigla and similar 

 fishes. 



Eadial formula: D. viii, 27; A. i, 25; V. i, 7; Br. viL 



Scales in lateral line 53, in transverse line 9-40. 



Color silvery, passing into roseate above and below. Fins yellowish; the ventrals 

 have the membrane black and the rays milky white. 



This species was originally described by Lowe from Madeira, and his specimen, eleven 

 inches in length, now in the British Museum, is believed to be the type. The TravaiUenr 

 obtained two specimens from the coast of Morocco, Station LXix, at a depth of 410 meters

OREOSOMA (After C. &, V.). 



Zeids with an elevated body and 2 dorsal fins, the first with 5 spines. A long anal, 

 composed entirely of rays. Opercles unarmed; operculum with two ridges terminating 

 in fiat angles. Villiform teeth on .jaws, vomer, and ])alatines. No scales, but numerous 

 large, conical, bony protuberances, symmetrically arranged.
