According to the very short and imperfect descriptions of 
the earlier authors this species has been confounded with 
H. galba, H. Latreillei, H. oblivia and others, or else, being con- 
sidered as a new species, it has got new names as Talitrus cyanece 
Sabine, Hyperia Lesuewrii Latreille, H. spinipes Boeck. In 
my opinion it. is evident that no animal but that here de- 
seribed can be identified with the Paulex cancriformis antennmis 
brevissimis Strom, as the characteristic quoted by him, I. c., 
p. 189: »De to ferste Par Fedder ere lodne eller flossede, i 
Enden stumpede» agrees well with this animal, but not with 
ke ovher > Hyperie. The animal deseribed by O: Fabricius 
in his »Fauna groenlandica» under the name Omniscus medusarum 
18 another species, possibly identical with Hyperoche Kroeyert 
or H. abyssorum (see below p. 564). The examination of the 
description and drawing of Talitrus cyanee given by Sabine 
(repa pli tj has convyimeed me that a true Hyperia 
medusarum has been the type of his new species. The Hy- 
peria cyanee of Spence Bate! is not the same species as 
Sabine's, but synonymous with FEuthemisto Nordenskiöldi (see 
below p- 570), probably his typieal specimen has been pre- 
served in the same phial as the original of Sabine, because 
he refers to the original label of Sabine. 
The diagnostical points of this species are the not produced 
carpi of the first pair of pereiopoda, the scarcely serrated, densely 
hirsute metacarpi and small dactyli of the first two pairs, and 
the length of these pairs in comparison with the two following. 
In general habitus it comes very near to H. Latreillei.
