SEVEN NEW SPECIES OF FISH OF THE ORDER 
MALACOPTERYGII. 
By W. W. WE tss, ? 
Scientific Assistant, United States Bureau of Fisheries. 
The following descriptions of seven new Malacopterygian fishes 
have been taken wholly from the unpublished notes of Mr. W. W. 
Welsh, formerly scientific assistant, United States Bureau of Fisheries, 
whose most unfortunate demise has placed this work of salvage on 
me, as the one who was most recently collaborating with Mr. Welsh 
in the study of fishes. 
All illustrations, except that of Aristostomias tittmanni, were pre- 
pared under the personal supervision of Mr. Welsh. That of Aristo- 
stomias tittmanna was made by Mrs. E. B. Decker, under the direc- 
tion of Mr. S. F. Hildebrand. Those of Eustomias prozimus and 
bigelowi were drawn by Mr. T. Van de Bogert, and the remainder 
are from my own pen. Mr. 5S. F. Hildebrand supplied the footnotes 
to the description of Aristostomias tittmanni and Eustomias enbarbatus.

Genus DIPLOPHIS. 
Diplophas GuNTHER, Journ. Mus. Godeffroy, vol. 2, 1873, p. 104. 
DIPLOPHOS MOOREI, new species. 
Three examples taken by the Bache, two, 43 and 33 mm. in length, 
at Station 10196, in the northeast Providence Channel, and one, 
39 mm. long, at Station 10202, 5 miles west from Gun Cay, in the 
Straits of Florida. The first two were taken at the surface, the third 
in a haul at 75 to 0 meters. 
This species differs markedly from known forms, in the shorter and 
deeper body, much lower anal count, and lesser number of photo- 
phores. 
Dorsal, 12; caudal, 20; anal, 38; ventrals, 8; pectorals, 9.
