(5) The absence of spines along the inner margin of the inner 
uropods. 
The last two characters will also serve to separate it from the 
remaining two species of the genus: P. ahyssicola (which is doubt- 
fuUy distinct from P. obesa) and P. spectabilis. 
The species is a deep water form but at suitable depths.

Brutomysis vogtii, Lo Bianco (1901; nec Chun, 1896). 
Eucìiaetomera tennis (pars), Lo Bianco (1903). 
E. fowleri, Holt & Tattersall (1905 and 1906). 
The specimen from St. 43. 1901, came to me labelled Bruto- 
mysis vogtii and is evidently the single specimen recorded under 
that name by Dr. Lo Bianco (1901). On examination it proved to 
belong undoubtedly to Euchaetomera tennis. As no further specimens 
of Brutomysis vogtii occur in the collection, this species must be 
deleted from the Mediterranean list, its place being taken by Euchae- 
tomera tennis. In a reccnt letter, Dr. H. J. Hansen informs me that, 
after examining the type of E. tennis G. 0. Sars, he regards the 
latter and E. foivteri Holt & Tattersall as one and the same species. 
Mr. E. W. L. Holt has kindly compared for me the types of E. tennis 
and E. fowleri and entirely agrees with Dr. Hansen. Accordingly I 
bere adopt Dr. Hansen's conclusion and sink E. foivleri as a syno- 
nym of E. tennis. Dr. Lo Bianco's originai records of the latter 
species from the Mediterranean^ therefore, remains correct, except 
in so far as they refer to the following species. E. tennis is evi- 
dently very rare in the Mediterranean, having been captured only on 
one occasion during each cruise though gatherings were made at 
several stations over depths suitable for its capture. 
Euchaetomeropsis gen. nov. 
Euchaetomera (^2ix^\ Lo Bianco (1901 and 1903). ^7.,Illig(1908). 
In accordance with a Suggestion made by Holt & Tatter- 
sall (1906), I define this genus for the species recently named 
Euchaetomera merolepis by Illig. Specimens of this species were 
communicated to the authors named, by Dr. Lo Bianco, and in 
noting its occurrence, without, however, naming it, they pointed out 
that the character of the antennal scale excluded it from the genus 
Euchaetomera. Illig does not seem to bave been aware of this 
note when naming the species and he retains the latter in the
