dorsal surface; the egg mass is a bright green-blue; the eyes are brown. 

 In the younger, or smaller individuals the star-shaped marks are con- 

 fluent over the whole surface of the thorax and abdomen. The horns 

 between eyes are very small. The frontal horn is large and broad, 

 rounded. The eyes are large and close together. Twelve specimens, 

 parasitic on lane snapper (Neomsenis synagris) . The color is white, the 

 dorsal surface with one or two rows of brown star-shaped spots across 

 each segment; the eyes are dark blue- black. The frontal horn is 

 very large, rounded, produced, upturned. The eyes of both sexes are 

 large and close together. Eight specimens, parasitic in eye sockets 

 of the yellow-tail (Ocyurus chrysurus). The color is light brownish- 

 yellow, with a row of brown star-shaped spots across each segment 

 on the dorsal surface; the eyes are dark seal-brown; the egg masses 

 are a bright salmon-pink. All the horns on the head are small, the 

 two posterior ones almost obsolete. The eyes in both sexes are very 

 large and close together. Four specimens, parasitic in the eyes of the 

 yellow-tail {Ocyurus chrysurus) . The color is a light yellowish- white, 

 each segment with a single row of brown spots across the dorsal sur- 

 face. The eyes are very large and close together, almost confluent 

 in one specimen. One specimen, from the fins of the sea-pcrcupine 

 (Diodon Jiystrix) . The color is gray- white, with a row of brown star- 

 shaped spots across the dorsal surface of each segment ; the eyes are 

 dark brown. This is probably an immature female. (Collected by 

 C.B.Wilson.) 



One specimen from White Rock, from the gill cavity of the rock- 

 hind (Epinephelus adscencionis) . The color of the ventral surface is 

 white, of the dorsal surface white, nearly covered with a loose pattern 

 of light reddish-brown; the eyes are black; the claws on the tips of 

 the legs red-brown ; the legs themselves white.

Locality. — Montego Bay; parasitic on the French grunt (Esemulon 

 Jlavolineatum) . The color is beautifully variegated in delicate shades 

 of brown, pink, and gray. The head and first three segments and 

 the abdomen are delicate pink with fine dots and lines of red-brown 

 on the dorsal surface; the remaining thoracic segments are a light 

 olive-gray, with variegated spots, lines, and blotches of dark olive- 

 green, the fourth segment with a prominent wide transverse band 

 of dark brown spots; all the segments have a narrow band of red- 

 brown on the lateral margins; the telson has a central crescent of 

 black spots shaped like this £j[y, the eyes light pink; the egg mass 

 is jet-black.
