Aulopidm, Cope, Trans. Ainer. Phil. Sot-, xiv, 455; Proc. American Assoc. Adv. Science, 1870, 333. 



Aulojiida; (restricted) Gill, MS. 



The family Aulopidce is characterized by the maxillary dilated behind, and the exten- 

 sion downwards of the hypocoracoids, as in many Acanthopterygii ( Gill, MS.). Cope's defi- 

 nition was inaccurate. 



A. Dorsal preinedian. Rays not filamentous. 



1. Palatine and tongue with teeth. Adipose fin present, small. 



a. Vcntrals not in front of dorsal. Snout conical Chlokc ipiithalmus. 



B. Dorsal postmediau. Rays of some of the fins filamentous. 



1. Second and third dorsal rays prolonged, filamentous. Palate and tongue toothed. . . [Aulopus].

 Hyphalonedrus, Goode, Proc. U. S. Nat. Mus., 1881, 483. 



Body rounded, terete, mouth wide, mamillaries long, posteriorly dilated. Teeth minute, 

 in narrow bands on jaws, and on palatines, vomer, and tongue. Ventrals behind origin of 

 dorsal. Adipose fin small. Anal short. Gill opening very wide. Branchiostegals 10. 

 Pseudobrauchiai well developed. Scales pectinate.

Height of body 5J in total length ; head 3A in same. Eye very large, its diameter nearly 

 one-half length of head. Dorsal origin at one-third the distance from snout to base of caudal 

 rays. Its height is about equal to that of the ventral and is contained •"> times in total 

 length. Anal insertion about three-fourths of distance from snout to base of caudal. Ven- 

 tral inserted under middle of dorsal. Pectorals reach nearly to the middle of the length of 

 the body. Color greenish bronze, with silvery reflections. 



Kadial formula: D. 11-12; A. 9; L. lat. 60-63. 



This form occurs about Naples and Sicily, where it is rare. The National Museum has 

 specimens from Messina (So. 40071), sent by the Florence Museum. It also occurs at con- 

 siderable depths in the eastern Atlantic. The French expedition obtained it off the Azores 

 in 1,440 meters, also iu the Sargasso Sea, 405 meters, and off the Cape Verdes, 4(50 to 580 

 meters. 



The Albatross obtained specimens from various localities as follows: Stations 2314, lat. 

 32° 43' K, Ion. 77° 51' W., 159 fathoms; 2667, lat, 30° 53' K, Ion. 70 '-• 42' 30" W., 273 fath- 

 oms; 2264, lat, 37° 07' 50" K, Ion. 74= 34' 20" W., 167 fathoms; 239S, lat, 28° 45' K, Ion. 

 86° 26' W., 227 fathoms; 2543, lat. 39° 58' 15" K, Ion. 70=42' 30" W., 106 fathoms; 2624, lat. 

 32Q 36' N., Ion. 77° 29' 15" W., 258 fathoms. 



CHLOROPHTHALMUS CHALYBEIUS, Goode. (Figure 71.)

Bull. Mus. Comp. Zool., x, 223. 

 Chlorophthalmus Agassizii, tii nther, Challenger Report, xxu, 192, pi. L. C. 



Body terete, its height 6^ iu its length, its width 1$. The least height of the tail is 

 half that of thebody. The scales are moderately strong, sharply pectinated at the edge, and 

 arranged iu regular transverse rows, overlapping in such a manner as to resemble oblique 

 plates upon the sides. The lateral line is prominent, straight, containing about 48 scales.
