130 A. E. SHIPLEY. 
A single specimen, 3cm. long and 7 mm. broad at its broadest. The proboscis much 
shrunk, but in life as long as the body. The characteristic spiral funnels of the two pairs 
of nephridia were very evident. 
Locality. Hulule, Maldive Islands, also recorded from Amboyna. 
6. Thalassema vegrande Lampert. 
Shipley. Willey’s Zoological Results, Part 111. 1899, p. 352. 
Two specimens of this species were taken at Hulule. In many specimens of the 
Echiuroids collected on this expedition the proboscis had parted from the body but it had 
always been carefully preserved. In this case there was no trace of proboscis on the 
animal or loose in the bottle. The specimens were slightly shorter than those hitherto 
described but the skin seemed much contracted and was not so thin and papery as the 
latter. 
Locality. Hulule, Maldive Islands. This species has also been described from the 
Philippines and from Rotuma. 
EXPLANATION OF PLATE VI.

colour of the living animals.
