COLORS. Chiniicra collici, of which an immature specimen is pictured in plate xi, shows lustrous colors when taken from the water. Its ground tone is silver, but at every movement it reflects metallic hues—brass, copper, and gold. Its snout is trans-. Fig. 2.—Photograph of living Chimaera colliei. This shows the pectoral fins extended on either side of the body at the time of the down stroke of the fin. The pelvic fins stand out on either side apron-lilte. showing clearly their light-colored anterior border. In this position the spotting of the back is conspicuous. In lateral view (cf. fig. I ) the spots can scarcely be seen. lucent, its optic cuj) is luminous, refracting ]>ale greenish-blue, its iris brassy, and on head and trunk are tinges of rose, cobalt, pale-green, and madder. Out of water, however, its brilliant tones soon fade, and its delicate, scaleless skin blotches and dries. In the aquarium, as one could naturally expect, the fish fails to show much of its metallic luster, but, on the other hand, its pigments appear to greater advantage.

Its ventral region and fin bases are white, the fins themselves translucent and even tran
