BULLETIN OF THE UNITED STATES FISH COMMISSION. 
On October 28, 1896, several hauls with a 45-foot fine-meshed seine were made by Messrs. Ever- 
mann & Kendall in the Little River at various places in the last half mile of its course, and 35 fine 
specimens of this species were secured. They were found in all portions of the stream examined, in 
very brackish water about the mouth, in company with Neomwnis griseus and Lagodon rhomboides, and 
farther up where the water was perfectly fresh, and associated with such fresh-water fishes as Notropis, 
Abramis, Lucania, Jordanella, Heterandria, Acantharchus, and Elassoma. 
In studying the fishes collected in Florida by Dr. TI. M. Smith, in 1895, we find 3 specimens of 
this species which he obtained in Crocodile Hole, Indian Creek, a locality on the opposite side of 
Biscayne Bay from the mouth of Little River. 
Little River flows into Biscayne Bay a short distance north of Miami. It is a short stream, having 
its rise in the Everglades a few miles to the westward. At the mouth there are a good many mangrove 
bushes, but farther up the shores are lined with tall marsh grasses. The bottom is composed in most 
places of hard coral rock, worn into an irregular surface, over which it is difficult to haul a seine. In 
some places this rock is more even and is overlaid by a thick layer of mud and vegetable debris. The 
current was slow and the stream was well filled with such water plants as Myriop hyllum, Chara, Pota- 
mogeton, various species of filamentous alg;e, and an occasional patch of pickerel weed ( Pontederia ). 
The thirty-five specimens of Lophogobius cyprinoides from Little River vary in length from 1 to If 
inches. The following description is based upon one of the largest examples : 
Head 3£; depth 4; eye 4 in head; snout 4. D. vn-10; A. n, 8; P.16; scales 27, 9 in a transverse 
series, counting from origin of anal upward and forward to dorsal. 
Head very broad and heavy, its greatest width It in its length; snout short and blunt; mouth 
large, oblique, maxillary reaching vertical of pupil; teeth in a single series in each jaw, none on 
vomer or palatines ; gill membranes united to the isthmus, the gill slits wholly lateral ; branchiostegals 
4 ; jaws subequal; anterior nostril in a short tube; body compressed, tapering from head to the rather 
long, slender caudal peduncle, which is considerably expanded vertically at base of caudal fin ; least 
depth of caudal peduncle 2-J in head, depth at base of caudal fin 2 in head. Fins all large; origin of 
spinous dorsal at one-third distance from tip of snout to base of caudal, its base l-J- in head, its longest 
spine slightly greater than base of fin; the 2 dorsal fins not connected, the interspace very short; 
base of soft dorsal nearly equal to length of head, the rays all about equal in length, the last reaching 
base of caudal, in head; anal fin similar to the soft dorsal, immediately under it, the last rays 
reaching base of caudal; pectoral broad and long, the length equaling head, reaching past origin of 
anal; pectorals completely united, the middle rays reaching anal; caudal rounded, the middle rays 
longest; a high dermal crest from above eye nearly to origin of spinous dorsal, its height about 
equal to diameter of eye. Scales very large, finely ctenoid; no lateral line; head, nuchal region, and 
breast naked; cheek and opercles beautifully vermiculated with about 10 irregular lines of close-set 
mucous tubes. 
Color in adult, uniform dark brown, almost black on back and upper part of sides, somewhat 
paler beneath ; fins all black; entire head black. 
There is not much variation among the thirty-five specimens. The smaller individuals are 
somewhat more chunky in general form and the color is lighter. The nuchal dermal crest is present 
on all. 
OGTLBIA Jordan & Evermann, new genus of Brotulidas, allied to Dinematichthys. 
Type : Ogilbia cayorum Evermann & Kendall. 
Body moderately elongate, covered with small, smooth, embedded scales; no lateral line; sides of 
head with similar scales. Preopercle with its margin adnate, and mucous pores along its border; 
opercle with a small spine posteriorly; no barbels; jaws subequal; gape of mouth wide, the 
maxillary broadened posteriorly, but without distinct hook; teeth in jaws in bands, subequal; similar 
teeth on vomer aud palatines; lower lip without cirri. Gill membranes little connected, free from the 
isthmus; dorsal fin low, continuous, of soft rays only, inserted behind base of pectoral and not joined 
to the caudal, the base of the fin embedded in thick skin; anal similar to dorsal, but shorter; caudal 
small, rather pointed; pectorals moderate, inserted high; ventrals inserted before pectorals, each 
developed as a long filament of two soft rays. Anal papilla of the male without horny appendages 
or claspers. This genus is closely related to Dinematichthys, from which it differs in the absence of 
horny claspers to the anal papilla. Dinematichthys ventralis Gill, from the Pacific coast of Mexico,
