SYNGNATHID4E.

Corythrolehthys maenads sp. nov. Plate 2, lg. 3.

Rings 18+33; dorsal 19, on 1+4 rings; pectoral 12; caudal 10; anal 2. Head 9. Eye 5. Body 1.5 in tail. Cranial ridges strong, median keel on snout to middle of eye; ridge on occiput high, notched in front and behind. Supraocular ridge beginning in tubercle in front of center of eye; two ridges on opercle. Nostril double, in front of and near eye, tubed, dorsal tube short, ventral tube longer. Keels on body and tail strong; lateral keel of body running into ventral caudal keel. Belly convex, keel strong.

Body with 22 yellow and 22 brown bands, each covering from one to two body rings, some of which divide on the ventral surface of belly into rings and blotches of brown. Brown bands edged with darker. Bands on snout become irregular spots and blotches. First brown band crosses interorbital space through eye and obliquely downward and backward to large brown area on ventral surface of opercle.

Closely related to C. alhirostris, but well defined in color-markings. Vertebrae and body rings correspond.

Type, No. 3084, Zoological Museum, Princeton University. Length 10.5 cm. From bunch of coral off Ballenas Point.

Named for a party of friends from Ensenada, who obtained this specimen.

CHEILODrPTERED/E. Ands conklini sp. nov. Plate 3, fig. 1.

Head 2.6; depth 2.7; eye 2.6; interorbital 3.2; dorsal VI-I, 9; anal II, 9; scales 2-27-7; eye large, 2.5 in head; head broad; mouth rather large. Lateral line complete, following curve of back to caudal peduncle, where it dips down to center line. Anterior nostril near front of snout; posterior nostril large oval opening in front of center of eye.

Color orange-red with clusters of small black specks bordering scales over entire body. Caudal peduncle with large oblong black spot; caudal edged with black; spinous dorsal black; soft dorsal and anal with black bar at base; a black bar extending downward and backward on front of preopercle from eye; another bar extending transversely on nape and down on opercle, where it is more or less broken up into series of dots.

Differs from A. sellicauda in color markings, larger eye, and more robust body. Examples of A. sellicauda were obtained on the same coral reef, and this species differs distinctly from A. conklini, the proportions and color mark ings being quite different. A. conklini does not fade to white in spirits and the clusters of minute dark dots bordering each scale do not fade.

Two specimens, 4.5 and 5 cm. long, obtained with dynamite on coral reef off Guanica Harbor.

Type, No. 3080, Zoological Museum, Princeton University. Length, 5 cm. Paratype, No. 3128, Zoological Museum, Princeton University. 4.5 cm. long. Named for Professor E. G. Conklin.

Three specimens, 1.5 to 2.5 cm. long. Inhabits dead sea-urchin shells. Almost every sea-urchin skeleton in small muddy MS west of Guanica Har bor was inhabited by one of these delicate little fishes. The individual was never found more than a foot or two away from its shelter and when disturbed or approached darted into the shell. At low tide or when the surf was breaking over the mud flats the fish was invariably found inside the shell Measurements of the largest individual are as follows: Depth 3; head 2.7; eye 3; snout 5; scales 2-27-6. The chromatophores take the form of stel lations in spirit preparations. In life this fish is a uniform dark brown, almost black, with no evidence of bars or spots.
