DESCRIPTIONS OF NEW AND LITTLE-KNOWN FISHES. 
131 
Color grayish, darkest on anterior half of body, where each scale is dark brown on its basal half, 
then with a white ellipse, the narrow border darker, the contrast between the dark base and the 
white ellipse very marked; owing to the irregular arrangement of the scales the dark bases in some 
cases appear as spots ; upper side of caudal peduncle brown, sides nearly plain white ; snout and 
under parts of head lilac-brown; under parts of body rusty brown; tins all dark brown, especially 
the soft parts of dorsal and anal. 
LYOSPHiHRA, new genus of Diodoniidw, allied to Chilomycterus. 
Type: Lyosphcera globosa Evermann & Kendall. 
This genus is distinguished from Chilomycterus by its armature of flattish, papery or cartilaginous 
plates to which minute hair-like papillae are attached. The nostril, as in Diodon, is undivided. 
Etymology, Xvoo, to loose, i. e., lax or flabby; 6<f>aipa, sphere, ball. 
10. Lyosphaera globosa, new species. (PI. 9, figs. 11 and 12.) 
Type locality, the Rappahannock River near the mouth of Windmill Creek, Virginia, where 2 
specimens were collected by W. C. Kendall, July 18, 1892. Type, No. 48794 U. S. N. M. Associate 
type locality, Biscayne Bay at Cape Florida, Florida, 1 specimen. Cotype, No. 531 U. S. F. C. 
The type specimen is about 1J inches long and about 1 inch wide and deep. 
Head 3; depth 1J; eye 3^ in head; snout 4; D. 11; A. 4. Form oblong-ovoid ; head broad; inter- 
orbital space slightly convex, broad, its width H in head. Dorsal and anal far back, each separated 
from the caudal by a space equal to two-thirds diameter of eye, each very small, the anal rays scarcely 
distinguishable ; pectoral broad and short, with about 20 rays, the length less than interorbital width. 
Tooth of each jaw solid and continuous. Entire body sparsely covered with minute hair-like append- 
ages or flexible, dermal papillae, these very short inch in type), and appear to be two-rooted. 
Nostril a short, entire papilla with two lateral openings and no division at the tip. Ground color 
yellowish white, this color regularly broken up into hexagonal spots by a network of dark brown, 
the width of the brown spaces being usually less thau one-fourth the diameter of the spots, which are 
smallest on back and top of head; a villous papilla in the center of each spot. 
The two specimens from the Rappahannock agree closely, but the one from Cape Florida, which 
js a younger individual, differs from them somewhat in color. It may be described as being pale 
yellowish- white, covered with about 50 narrow dark-brown or blackish rings or circles, each inclos- 
ing a circular spot of pale, yellowish- white; these circles smallest on the back and not touching each 
other anywhere; on the belly they are distant from each other a distance about equal to their own 
diameter. It seems that as the fish grows older these dark rings approach each other and finally unite 
to form the reticulations seen in the two other specimens. 
We were at first disposed to regard these specimens as being the young of some known species, or 
possibly Trichodiodon pilosus 1 (Mitchill), but an examination of DeKay’s figure 2 shows that they can 
not be Mitchill’s species. It is equally apparent that they can not be Cuvier’s Diodon asper 3 4 or 
Gunther's Trichocyclus erinaceus:' 
Etymology, globosus, spherical. 
11. Lophogobius cyprinoides (Pallas). (PI. 9, fig. 13.) 
Gobius cyprinoides Pallas, Spicilegia, Zool., vm, 17, pi. l, fig. 5, 1770, Amboina(?); Poey, Reper- 
torio, i, 335, 1868. 
Lophogobius cyprinoides Poey, Synopsis, 393, 1868; Poey, Enumeratio, 125, 1876. 
Gobius crista-galli Valenciennes, in Cuvier & Valenciennes, Hist. Nat. Poiss., xii, 130, 1839, 
Havana (Coll. Poey) ; Poey, Repertorio, I, 335, 1868. 
One of the most interesting results of the recent investigations of the fish-fauna of the coastal 
waters of Florida is the finding of this remarkable goby in considerable numbers in the mouth of 
Little River, near Miami. It is a West Indian species, not hitherto known north of Cuba. The type 
used by Pallas is said to have come from Amboina, and the specimens which Valenciennes had came 
from Havana, whence they were sent by Professor Poey. Poey had specimens from Cuba, Haiti, 
Jamaica, and Santo Domingo.
