Aulopidw, (rostriiteil) (iiLi.. MS. 



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

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

 nition was inaccurate.

Height of body a.J in total length ; head 3i 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 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. 



Eadial formula: I). 11-12; A. 9; L. lat. 60-C3. 



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

 specimens from Messina. (No. 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 in tiie Sargasso Sea, 405 meters, and off' the Cape Verdes, 460 to 580 

 meters. 



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

 3L>o 43' N., Ion. 77° 51' W., 150 fathoms; 2()C7, lat. 30° 53' N., Ion. 70° 42' 30" W., 273 fath- 

 oms; 2264, lat. 37° 07' 50" N., Ion. 74° 34' 20" W., 167 fathoms; 2398, lat. 28o 45' N., Ion. 

 86° 26' W., 227 fathoms; 2543, lat. 39° 58' 15" N., Ion. 70° 42' 30" W., 166 fathoms; 2624, lat.

 Chlorophthalmus Ai/assizH, GOntueu, (^Iiallenger Report, xxii, 192, pi. L. C. 



Body terete, its height 6,| in its length, its width 7.f. The least height of the tail is 

 half that of the body. The scales are moileratcly strong, sharply pectinated at the edge, and 

 arranged in 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.
