258 DEEP-SEA FISHES OF THE ATLANTIC BASIN. 



backward. A very sbort filament above the orbit ia front and another one behind, whose 

 length (4: inillinieinoters) is abnnt one-third that of the eye. The head i.s entirely scaly 

 with the exci'ption of t he top of the .snont, and the integument covering the snpramaxilla 

 and the gill rakers has the same structure. The anterior nostrils are tubular, the tube 

 produced behind into a thin narrow Hap; tlie anterior nostril is at a distance from the eye 

 equal to tlie iiiterorbital width. The posterior nostril is not tubular. The distance of the 

 dorsal from the tip of the snout (36 millimeters) is twice the length of the maxilla. The 

 length of the first spine (10 millimeters) is about two- thirds the length of the the second (14 

 millimeters), the third and longest spine (16 millimeters) is one half as long as the head 

 without the snout. The penultimate spine (S millimeters) is nearly as long as the first, and 

 the last spine (10 millimeters) is about one-half the length of the upper jaw. The longest 

 ray of the dorsal (12 millimeters) equals one-third of the distance from tip of snout to dorsal. 



The length of the middle caudal rays (20 milimeters) is about one-half the length of the 

 hea'i. The caudal is almost truncated behind. The anal originates under the second ray 

 of the dorsal; the length of its base (10 millimeters) is one quarter the length of the head. 

 The length of the first spine (7 millimeters) is about two-thirds the length of the anal base; 

 the length of the second (17 millimeters) is about one-fifth of the standard length; length 

 of third spine (13 millimeters) is about equal to that of the eye. The longest ray (16 mil- 

 limeters) is equal to the longest spine of the dorsal. 



The longest ray of the pectoral (25 millimeters) equals the distance from the vent to 

 the origin of the ventral. Pectoral when extended reaches to the vent or to the vertical 

 from the penultimate dorsal si)ine. The ventral origin is under the base of the pectoral. 

 The fin reaches to the vent, its length (22 millimeters) a little greater than that of the 

 mandible. There are about 6 lows of scales, counted obliquely, from the origin of the 

 dorsal to the lateral line and about 10 below the line. There are about 22 tubes in the 

 lateral line. 



Radial formula: D. Xii, 10; A. III, 5; P. 17; V, i, 5. 



The colors of the alcoholic specimens have faded out. The type is now a very light 

 orange; fins all pale. There are faint traces of the existence of dusky blotches along the 

 back in life. 



The colors of the fresh specimen were as follows: Uniform rosy intermingled with 

 pearly white; the light areas most conspicuous on the tins. Anterior part of anal more 

 intensely colored than any other part of the fish. Cephalic tentacles pale; the posterior 

 supi'aocular pair with a little band of rose a little below the middle of the height. Pupil 

 an intense blue. Iris golden above and below, overlaid with rosy, greenish golden an- 

 teriorly and posteriorly. Belly and throat pearly white. The light areas on the caudal 

 simulate bands. 



The tyiie of the description is a single small individual measuring 88 millimeters to 

 the base of tlie caudal; total length, 110 millimeters, from station 2354, Albatross, N. lat. 

 20° 59' 30", W. Ion. 86^ 23' 45", off Yucatan, ti'om a depth of 130 fathoms. 



PONTINUS LONGISPINIS, Goode and Bean, n. s. (Figure 246.) 



The peculiar form of the spinous dorsal, noticeably in P. Knhlii, is quite marked in 

 our new species — that is to say, the third spine is longer than the fourth, and much longer 

 than the first and second. The gill-rakers also are stout, rather short, and not numerous, 

 while the pectoral rays are all small. The species is not so deep-bodied as IS. Kuhlii, the 

 greatest depth of the body (40 millimeters) being a little less than one-third of the stand- 

 ard length. The least height of the tail (12 millimeters) is one-fourth of tlie length of the 

 head. The length of the head (50 milhmeters) is about two-fifths of the standard length; 

 greatest width (27 millimeters) is a little more than one-half its length. The width of the 

 interorbital area (7 millimeters) is one-half the length of the eye. which is about equal 

 to the length of the snout. The length of the eye (15 millimeters) is contained 3.J 

 times in that of the head, or li times in the length of the postorbital part of the 

 head. The maxilla reaches to below the middle of the eye; its length (23 milhmeters) is
