76. Rhachotropis inflata G. O. Sars. 
Conspectus p. 184. 
Bredefjord St. 48, 2 spec.; St. 79, 30—50 m., 1 spec. 
Hitherto found in W. Greenland only in Nivak Fjord (abt. 6814? N.). 
77. Gammarus locusta L. 
Conspectus p. 192. 
Kvanefjord St. 10, 19,5—54 (?) m., 1 spec. — Bredefjord St. 29, 
taken at the surface, 1 spec. — Bredefjord Sermilik, Tasiusak, 
under stones at the shore, several specimens. 
It is remarkable that this extremely common and widely distri- 
buted species is not found in very great numbers in the “Rink” material.

— — Sexton, Schriften Physik.-ökonom. Gesellsch., Kö- 
nigsberg 1. Pr., vol. 54, 1913, Heft 1, p. 90, Pl. 4, fig. 2. 
In the stream at Narssak, Skovfjord, 6—vrrr, 1912, 1 spec. 
The specimen is small (abt. 7 mm.), and not a little defective. There 
are no setae in “clusters” on the antennae, which is perhaps due to 
the youth of the individual, but up. 3 and especially the 1. joint of p4 
are in excellent accordance with SEXTON’S figure; there are however, 
only 2 (not 3) teeth on the posterior portion of 1. joint in p4. 
The species is new for Greenland, it is known however, from North 
Germany (Königsberg to the Elbe) and from Irish lakes; it is found in 
salt, fresh and brackish water.
