Three secondary marginal tentacles and six sense organs in 
each octant. The subumbrella, the stomach and the stomachal 
pouches, and the tentacles are deeply reddish brown; in some 
specimens a number of large white eggs are present. 
Bigelow (1909) as well as May er (1910) suspect that 
Aeginura Weberi Maas is identical with A. Grimaldii Maas. In 
1908 Vanhoffen described two new species of the genus: guinensis 
with 5 secondary tentacles, and obscura with 4 secondary tentacles 
/ 
in each octant; I do not think this character nor the comparatively 
slight variation in colour is sufficient for describing new species; I 
am sure, in consequence, that the two species cannot be maintained. 
Aeginura Grimaldii , then, has a very wide distribution. Maas 
described the species from the North Atlantic, 47° 43' N. Lat., 
17° 10' W. Long. Later he described it as A. Weberi (Maas 
1905) from the Malayan Archipelago. The “Valdivia” Expedition 
(Vanhoffen 1908) found Aeginura (Cunoctona) Grimaldii var. 
munda and A. guinensis off the tropical coast of West Africa (the 
Guinea region), from great depths, and A. obscura in the depths off 
the German East Africa. Bigelow (1909) records A. Grimaldii 
from the eastern tropical Pacific. — All the records are from deep
