THE LIFE COLORS OF CREMNOBATES INTVEGRIPINNIS., 
By ROSA SMITH. 
The type specimens of this species were described (Proc. U. 8. Nat. 
Mus., 1880, 147) after the color markings were changed from immersion 
in alcohol. The following description is made from two living ex- 
amples: Ground color, light purplish brown; top of head and snout, 
greenish yellow; a broad streak of coralline pink, closely resembling 
the color of Callithamnion heteromorphum, from eye across cheek and 
opercles; the base of the pectoral fin is of this color, outlined by a 
black crescent, beyond which the tips are transparent and pale green, 
dotted with black. On the side of body below lateral line are three 
orange-colored, nearly circular blotches, the anterior one overlapped 
but not entirely covered by the tips of the pectoral, the first spot equal- 
ing or larger than the orbit, the two posterior ones somewhat smaller. 
Dorsal fin with eight nearly square purple spots, alternating with lighter 
spaces of similar size and shape; the seventh dark dorsal spot is a 
green ocellus (black in the preserved specimen) encircled with a narrow 
ring of orange color and surrounded with very dark green, the ocellus 
covering the twenty-fourth, twenty-fifth, and twenty-sixth dorsal spines. 
The lips are pale green. A white dot at base of occipital tentacle as 
large as pupil; minute white dots along lateral line from its origin to 
the pointof curvature, and a larger white dot close under the twenty- 
first or twenty-second dorsal spine. Anal fin marked with dark spots 
similarly to the dorsal and narrowly margined with white. Caudal 
transparent, pale green, dotted with black. Ventrals obscurely barred 
with black. Ventral surface lighter than sides of body. 
Lower rays of pectorals projecting beyond membrane, the upper rays 
much less projecting. 
Beginning of anal fin a little nearer tip of snout than base of caudal. 
The number of fin rays and all other characters agree with the original 
description. 
One of the present examples was taken February 6, 1883, with a dip- 
net, from a shallow tide pool about 4 by 6 feet in diameter, two or three 
miles distant from the locality where this species was discovered. The 
floor of the pool was of sand and no pools intervened between it and 
the sand beach, so that this one would be unsurrounded with water at
