Danaella mimonectes (n. gen., n. sp.), 
a new bathypelagic Gammarid (Fam. Lysianassidæ) from 
South Greenland waters. 
By 
K. Stephensen. 
During the fishery investigations carried out by the “Dana” 
by Prof. Ad. S. Jensen in Greenland waters in the spring and 
summer of 1925 a specimen of a very remarkable new Amphipod 
was secured. 
The locality was: “ Dana” St. 2401: 61M7’ N, 52« 55’ W, 3000 m, 
1900 m wire, 9—7 — 1925, 2^« pm. At the same locality the following 
pelagic species of the fam. Lysianassidæ were secured: 
Cyphocaris anonyx Boeck, abt. 15 spec„ including some ? ovig. 
(on the species see my paper on the “ Ingolf“-Amphipoda pt. 1 
[Danish “Ingolf” Exped. vol. III, 8, 1923, p. 50]). 
Metacyphocaris Helgce Tattersall, 5 spec. (see ibid. p. 54). 
Koroga megalops Holmes, 1 spec. (see ibid. p. 60), and 
Katius otei/s Chevreux, 4 spec. (see ibid. pt. 2, “Ingolf”, vol. III, 9, 
1925, p. 126). 
Later on I have found a second specimen in the material col- 
lected by the “Dana”. 
Genus Danaella n. gen. 
The body is globular, but the globe essentially consists of the highly 
inflated third to sixth mesosome segments. The head and the first 
and second mesosome segments are small, and the seventh segment 
is somewhat compressed and narrow, in dorsal view not much broader 
than the compressed metasome segments. The urosome possibly 
consists of only two segments; but if my interpretation is correct.
