BLENNIIDAE. 157 
nate at lower edge of brown caudal spot; between this series and the soft dorsal 
are numerous round white spots and vermiculate white lines. 
A female 2% inches long has the following measurements: — head 4.54 in 
total length without caudal; depth 5.55; eye 4.05 in head; dorsal XII, 20; anal 
IJ, 20; interorbital very narrow; ocular cirrus long and fringed on both sides; 
nasal cirrus comparatively long and simple; no cirrus on nape; crest well de- 
veloped. 
Color of head and body very similar to that of the male, but on the middle 
of the under lip there are two short converging lines; pectoral, ventral, anal, and 
caudal pale, but finely punctulate with dusky; caudal having a yellowish area 
and brown spots at its base; Ist and 2nd dorsal similar to those of male, but 
much paler. 
Of the remaining four specimens three are females having dorsal XII, 19 
and anal ii, 20, the two anterior represented by the 11 being shorter than the 
others, the first papilla-like, and separated from the rest of the fin; the second 
- connected by a membrane and may be considered a ray. 
The fourth and smallest specimen is a male having dorsal XII, 20 and anal 
ii, 21, the anterior of which is a simple papilla and the second a short ray con- 
nected by a membrane to the rest of the fin. 
These specimens agree perfectly with the description of Salarias biseriatus 
Cuvier and Valenciennes (loc. cit.) and the description and figure by Kner in 
Novara Reise Fische, 1865, p. 197, taf. 8, fig. 4, with the exception that both of 
these authors state that there are no posterior canine teeth on the lower jaw; 
the present specimens possess large canine teeth, although their location is such 
that they might be easily overlooked. Dr. Steindachner has kindly sent us 
one of Kner’s specimens taken at Tahiti. Upon examination we find that it 
possesses large canines well back in the mouth but in such a position as to be 
easily overlooked. It is a female without crest, containing well-developed eggs. 
Specimens in the Reserve Series of the U. 8. Bureau of Fisheries have been 
misidentified as Salarias biseriatus by Jordan and Seale, Bull. U. S. Bur. Fish. 
1906, 25, p. 427. These we describe as 
Alticus margaritatus, sp. nov.
