lips as there are radial canals. The radial canals enter the stomach at the 
highest point, and do not extend down the peduncle. The entoderm is deli- 
cate blue-green. Common off the. Florida coast and Bahamas.

Bell half egg-shape; less than 2 mm. in diameter. Bell-walls thin and 
uniform. Eight large unbranched tentacles, the distal ends of which bend 
outward. The inner and lateral sides of each of these tentacles bear 3-10 
flexible cirri which are besprinkled with wart-like clusters of nematocysts 
and terminate in a knob. There is a large ectodermal, cup-like ocellus, with 
a lens upon the outer side of each tentacle bulb. Velum large, and with 
circular striations. Manubrium large and spindle-shaped with about six 
rounded protruding pouches at its widest part. Mouth surrounded by five 
oral tentacles, each ending in a ball of nematocysts. The manubrium is thus 
octameral at top, hexameral in the middle, and a five-pointed star at the 
mouth. Genital products develop in the ectoderm of a large part of the ma- 
nubrium. Ocelli black, all other parts colorless. Found by Dr. H. F. Per- 
kins swimming on the surface at night in July, 1902, in Nassau Harbor, 
Bahamas.

THE OLINDIADi^.* 
The most characteristic medusae of the shallow water of the Bahama banks 
are species of Cubaia (Gonionemoides) and Olindias. These together with 
Olindioides, Gonionemus, Vallentinia, and possibly Limnocnida and Limno- 
codium may be grouped under a single family. 
Olindiudoe: With a pad-like cluster of modified nematocyst cells upon the 
aboral side, near the distal extremity, of some or all of the tentacles. With 
four or six radial canals, and with or without blindly-ending centripetal 
canals. With gonads upon the radialcanals.
