Corrections to the paper on the Malacostraca 
from the Tjalfe-Expedition. 
By 
K. Stephensen, 
Åcanthephyra (p. 64). 
During a visit to Copenhagen last summer (1912) Cand. real. 
O. Sund, Assistant at the Fisheries-Investigation in Bergen, Norway, 
studied the material of the genera Acanthephyra and Pasiphae 
preserved in the Zoological Museum in Copenhagen. At the named 
time I was on a zoological research in Greenland; but Mr. O. 
Sund has left a note, wherein he writes that all the specimens 
of 4. purpurea M. Edw. in our museum do not belong to this 
species, but to Å. multispina Coutiére, and after my return from 
Greenland I have convinced my-self that he is right.  Accordingly 
all the Greenland specimens of the genus Acanthephyra, also those 
from the ,,Tjalfe”-Expedition, in reality belong to A. mudtispina. 
A short report will be given in Conspectus Crustaceorum et 
Pycnogonidorum Groenlandiæ, Meddel. om Grønland vol. 22, 1913, 
p. 44—47; but later on I intend to give the results of a closer 
examination in: Crustacea, in Report on the Danish Oceanographical 
Expeditions 1908—1910 to the Mediterranean and adjacent seas, 
published at the cost of the Carlsberg Fund under superintendance 
of Johs. Schmidt, Ph. D. 
Boreomysis tridens and B. nobilis (p. 78). 
On account of a very unfortunate mistake I have on 3 of the 
labels for B. tridens in stead of the right name written B. nobilis.
