in the number of centripetal canals. The specimens with triangular gonads have always 

 three centripetal canals in each quadrant, even in the intermediate stages when the gonads 

 are beginning to develop. The specimens with elongated oval gonads have only one 

 centripetal canal in each quadrant and the gonads begin as linear enlargements of the 

 radial canals. 



Liriope was found at 27 stations. A good haul was made north of Chagos (17 May, 

 1905, C.) when 78 specimens were taken. These were mostly early stages with a few 

 adults of Liriope sp. Another large haul of the same species was made at the Farquhar 

 Isles (1 Oct. 1905, v.). Except at these two stations Liriope was rather scarce.

The specimens are early stages and not in good condition. The smallest, about 3 mm. 

 in diameter, has one centripetal canal in each interradius, and the perradial hollow tentacles 

 are just beginning to develop. The largest specimen, about 8 mm. in diameter, has three 

 centripetal canals in each interradial sextant. The gonads are beginning to develop. Two 

 of the sense organs have two otoliths instead of the usual single one. 



Distribution. At the surface in the tropical and warm regions of all the Oceans, and 

 in the Mediterranean.

Description : — The umbrella is about 5 mm. in diameter, slightly curved, and 

 moderately thin. The marginal lappets are about as broad as long, and curved on the 

 outer edge. Velum narrow. The stomach is circular, its lower .wall rather loose, and 

 the mouth closed in the form of projecting lips. There are broad marginal canals, but not
