ART. 3. NEW SPECIES OF FISH——-WEISH. | 
A small triangular luminous area close to maxillary behind vertical 
from posterior margin of eye; two rows of small, circular, nearly equi- 
distant photophores along side of body ventrally, extending to about 
the 6th anal ray; from this point to the caudal peduncle a single 
intermediate row of somewhat larger photophores; upper row, gill 
opening to ventrals, 29; ventrals to anal, 10; along anal, 4; lower row, 
isthmus to pectorals, 9; pectorals to ventrals, 29; ventrals to anal, 
10; along anal, 4; intermediate row along anal to caudal peduncle, 21. 
Dorsal origin over 15th anal ray; distance from tip of snout to origin 
of dorsal 1.15, to anal 1.33, to ventral 1.74, to pectoral 7.35; ventrals 
1.6 in head, the rays not divided into two groups; pectorals 1.5 in head, 
the rays filamentous, closely united for a short distance at base. 
Color in alcohol, body and head velvety black, with minute white 
granulations, these most abundant along lower row of photophores; 
barbel black, its conical tip and 
filaments white; dorsal and anal 
nearly colorless, their rays pig- 
mented basally, the last 10 banded 
with black at segments; ventrals 
colorless, the rays evenly pig- 
mented with black; pectorals 
black. 
Type.—Cat.No.84284,U.S.N.M., 
102 mm. long, taken with a townet 
at Station 101634, 170 miles southeast from Cape Hatteras, at a 
depth of from 500 to 0 meters. 
One other example, 88 mm. long, anal count 42, taken in a townet 
at Station 10162, 120 miles east-southeast from Cape Hatteras, at a 
depth of from 150 to 0 meters. 
(bigelowi, named for Dr. H. B. Bigelow, of the Cambridge Museum 
of Comparative Zoology.) 
FIG. 6.—EUSTOMIAS BIGELOWI, TIP OF BARBEL. 
EUSTOMIAS ENBARBATUS, new species. 
This species approaches F. obscurus Vaillant and EF. proximus, but 
differs from them in the number and arrangement of the photo- 
phores, in which it closely resembles F. bigelowit. From the latter 
it differs in the number of anal rays, the number and character of 
the pectoral rays, and the length and form of the barbel.* 
4The author has mentioned the close relationship of his species, Fustomias enbarbatus, and #. 
obscurus Vaillant, calling attention to the difference in the arrangement of the photophores. A com- 
parison of the type of FZ. enbarbatus with the drawing and description of the type of Z. obscurus has 
revealed a few other differences worthy of note for the convenience of the student. 
a. The ventral fins in E. obscurus are divided into two parts, the upper division consisting of 
three short rays and the lower of four long rays. These fins are undivided in Z. enbarbatus. 
b. The head in E. obscurus is not notably elevated and the profile is little concave over the snout 
and only slightly convex from the head to the nape. In Z. enbarbatus, as shown in the drawing, the 
head is much elevated, the profile is concave over the snout and strongly convex Over the head 
c. A very great difference is evident in the detail structure of the barbel. The bulbs at the end of 
these organs are different in shape and the tentacles attached thereto are also very different. For the 
structure of those of E. enbarbatus refer to figure 8. Those of EZ. obscuwrus are seven in number, all origi- 
nating from the distal end of the large bulb, and each tentacle in turn ending in a small bulb.
