black ; the dorsal filament whitish. 
GoBIUS SEMINUDUS. 
6] 15. Ay10, 
Head and anterior portion of the trunk naked ; sides with exceed- 
ingly small scales, becoming somewhat larger posteriorly. The 
height of the body is one-sixth of the total length, the length of the 
head one-fourth. Head with the cheeks swollen, depressed, broader 
than high, its width being two-thirds of its length. Eyes close to- 
gether, directed upwards, of moderate size ; snout obtuse, as long as 
the eye; cleft of the mouth slightly oblique, with the jaws equal 
anteriorly, and with the maxillary extending to below the middle of 
the eye. Teeth in villiform bands, the anterior of the lower jaw 
slightly enlarged ; there are two small curved canine teeth on each 
side of the lower jaw. Dorsal fins rather low, the hind part of the 
spinous dorsal being scarcely lower than the anterior ; caudal round- 
ed, as long as the pectoral; none of the pectoral rays silk-like ; 
ventral rather short, terminating at a great distance from the vent. 
Blackish, fins and sides of the head dotted with black ; ventrals black. 
The largest of the specimens examined is two inches long. The 
species has such peculiar characters that it will be readily recognized. 
It has no natural affinity to the other small-scaled Gobies, which 
generally have an elongate form.

Deb] Was ok b4.,) de late. 
Twenty longitudinal series of scales between the dorsal fin and the 
anus, twelve between the anterior portion of the second dorsal and 
the anal. The height of the body is one-eighth of the total length, 
the length of the head five times and two-thirds. The head is as 
high as broad, its width being somewhat more than one-half of its 
length. Eyes very close together. Snout obtuse, shorter than the 
eye, the diameter of which is one-fourth of the length of the head. 
Cleft of the mouth slightly oblique, with the jaws equal anteriorly, 
and with the maxillary not extending to below the centre of the eye. 
Head naked ; scales on the nape and behind the axil very small, be- 
coming larger posteriorly. The second dorsal spine is the longest, 
somewhat lower than the body underneath, but higher than the soft 
dorsal ; caudal rather elongate and pointed, two-ninths of the tota! 
length. Pectoral shorter than the head; the ventral terminates at a 
great distance from the vent. Light greenish olive with a series of 
four brown spots along the middle of the tail; sides of the head 
with some irregular blackish-violet blotches; dorsal, caudal, and 
pectoral fins dotted with black, ventral and anal immaculate. 
This species has a second series of very small teeth within the 
maxillary front series; these internal teeth do not appear to be’ 
fully developed, but destined to replace those in function. The teeth 
of the lower jaw form a very narrow band anteriorly, and stand in a 
single series posteriorly.
