Aulopidw, (restricted) Gill, MS. 



The family Aulopidw is characterized by the maxillary dilated beliiud, and the exten- 

 sion downwards of the hyijocoracoids, as in many Acauthopterygii [Gill, MS.). Cope's defi- 

 nition was iuaccnrate.

 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.

Height of body 5J in total length ; head 3.J 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 5 times in total 

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

 tral inserted under middle of dorsal. l*ectorals reach nearly to the middle of the length of 

 the body. Color greenish bronze, with silvery retiections. 



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



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

 specimens from Messina (No. 40071), seat by the Florence Museum. It ahso 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 oft' the Cape Verdes, 460 to 580 

 meters. 



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

 32° 43' K, Ion. 77° 51' W., 159 fathoms; 2067, lat. 30° 53' N., Ion. 79° 42' 30" W., 273 fath- 

 oms; 2264, lat. 370 07' 50" K, Ion. 74'^ 34' 20" W., 107 fathoms; 2398, lat. 28° 45' K, lou. 

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

 320 36' JSr., Ion. 770 29' 15" W., 258 fathoms.

 Chlorophthalmus Agassizii, GuNTUER, Challenger Report, xxii, 192, pi. L. C. 



Body terete, its height 6J iu its length, its width 7^. Tlie least height of the tail is 

 half that (jf the body. The scales are moilcrately strong, sharply pectinated at the edge, and 

 arranged iu regular transver.se rows, overlapping in such a manuer as to resemble oblique 

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