ON THE OCCURRENCE OF A SPECIES OF CREMNOBATES AT SAN 
DIEGO, CALEFORNEA. 
By ROSA SMITH. 
Three specimens of a small scaly Blenny found in those rocky tide- 
pools which are heavily lined with algie, on March 6, 1880. 
This Blenny is evidently of rare occurrence, this one point being at 
present its only known habitat on the Pacifie coast of the United 
States, and these three specimens the only ones I could procure. It is 
accompanied by Oligocottus analis, which in this vicinity is abundant in 
all rock-pools, by Gibbonsia elegans of a dull color, and by Hypleurochi- 
lus gentilis. 
These specimens were provisionally identified as belonging to Oremno- 
bates monophthalmus (Giinther) Steindachner (Anchenopterus monoph- 
thalmus Giinther, Cat. Fishes Brit. Mus., iii, 275), a species hitherto 
known from three examples from the Pacific coast of Central America. 
My specimens differ from Giinther’s description in the following partic- 
ulars: The dorsal fin is continuous, the membrane of the third spine 
joining the fourth near its summit in two examples, at its first third 
in the other. The head is proportionally shorter, forming two-ninths of 
the total length instead of one-fourth, and the body is less elongate, 
its depth forming one-fifth the total length instead of one-sixth. The 
characters of the San Diegan form of this genus agree more closely 
with Steindachner’s description of Cremnobates affinis (Ichthyologische 
Beitriige, v, 178), a species considered by its describer as doubtfully 
distinct from C. monophthalmus. C. affinis is known from one individual 
taken on the West Indian island of St. Thomas, the proportions and 
coloration of which accord with my specimens, but this species also has 
the membrane from the third dorsal spine joining the fourth at its base 
(‘die Membrane des dritten letzten Strahles setzt sich an die Basis des 
folgenden ersten Stachels des zweiten Dorsales an”). 
If the specimens from San Diego prove to be of a distinct species, 
which seems probable, they will be separated from those already known 
by the single merely emarginate dorsal fin, instead of two separate 
fins. In any event, the genus Cremnobates furnishes an interesting 
addition to the fauna of our Pacific coast. 
Cremnobates integripinnis sp. nov. 
DESCRIPTION.—The body is oblong, compressed. The head is less 
than the fourth of the total length, which measures two inches and an 
eighth. Gape of mouth oblique, the maxillaries reaching a vertical 
line intersecting posterior rim of orbit. Head conical, thickish, with 
the orbits placed far forward, small fringed tentacles on their superior 
margins, a tentacle on posterior margin of anterior nostril, and palmate 
tentacles on occiput. A cusp or spine on opercle. 
Dorsal continuous, composed wholly of spines of nearly equal height
