192 DEEP SEA FISHES. 



Scales large, with prominent concentric strife, cycloid, in ten longitudinal 

 and sixty to sixty-five transverse series, in eight series along the caudal 

 pedicel. Lateral line a deep groove curving upward from the upper angle 

 of the gill o2)ening till close to the median line near which it continues 

 along the sides of the dorsal to within about fifteen rays of the end of 

 this fin where it ends abruptly. An air bladder. Two pyloric cajca, short 

 and thick. In a female of one and one fourth inches the ova are nearly 

 or quite mature. Largest specimen measuring one and seven eighths 

 inches. 



Flanks, cheeks, and iris silver}^; back appearing brownish from numerous 

 small spots ; top of head darker. There is a long group of small spots, near 

 the hinder part of the first section of the anal, on the lower edge of the 

 flank passing backward a short distance along the second part of the fin. 

 A group of the spots at the base of the caudal. Entire ventral surface light 

 excej^t in a series of blackish dots at the bases of the anal rays, anteriorly 

 in the fold and more or less complete backward ; these are covered by 

 membranes and simulate the luminous spots of the Scopeloids.

This species has a larger eye than either Brcgmaceros 3Iacdellandii or 

 B. atlanticits and its snout is shorter, more blunt, and less conical. B. longipes 

 is less closely allied to either of the last two than they are to one another. 

 B. Macdellandii has been reported from the China Seas and from the Philip- 

 pines to Bengal, where Alcock notes its occurrence from 128 fathoms. 

 B. atlanticus was taken by the steamer *• Blake," in the West Indies off 

 Nevis and Grenada and in the Gulf of Mexico, lat. 25° 33' N., Ion. 84° 

 21' W. in depths varying from 101 to 305 fathoms. 



MACRUROIDS. 



This is a deep sea family of which a few members are found near the 

 surface. It contains a small number of genera, but the latter are made up 

 of a large number of species and these, again, judging from their abundance 

 in the dredges and trawls, include hosts of individuals. The family gener- 

 ally is well adapted to bathj'bial conditions, even in the few species dwelling 

 in the shoaler waters, and probably is distributed from the Arctic to the 

 Antarctic regions in all the oceans. Immense numbers of individuals, with
