272 Part ITI.—Nineteenth Annual Report 
British record for Arcturella that I at present know of is that of the late 
Dr. Robertson of Millport for the Clyde; he dredged it off Blackwater- 
foot, Arran, Firth of Clyde, in 20 fathoms.* 
MUNNIDA, 
Paramunne bilobata, G. O, Sars. 
This small species was obtained in a gathering collected south-east of 
Fair Island on October 19th, in about 65 fathoms. This species, though 
small, is quite distinct, and appears to be extensively distributed around 
the Scottish coasts. It is one of the species obtained in the stomachs of 
small Haddocks captured sixty-five miles south-east by east of Sumburgh 
Head on September 4th, 1900. 
Pleurogonium imerme, G. O. Sars. 
P. inerme was dredged off Aberdeen by the ‘‘ Garland ” in 45 fathoms 
on November 7th, 1200. 
Pleurogonium spinosissimum, G. O. Sars. 
One or two specimens of this distinct species were dredged by the 
“Garland ” in the Sound of Mull in 72 fathoms on March 31st, 1900. 
DESMOSOMIDA. 
Macrostylis spinifera, G. O. Sars. (PL XVIIL, fig. 39.) 
A single damaged specimen, which is represented by figure 39 on Plate 
XVIII., was obtained amongst a small quantity of sand collected by the 
“St. Andrew ” about fifty miles south-east of Fair Island on October 19th, 
1900 ; nearly all the appendages of the specimen were broken off—even 
the styliform uropods were damaged. The species was obtained in about 
65 fathoms, and is an addition to the British fauna. Prof, Sars meutions 
that it occurs in a few Norwegian localities, from the Lofoten Islands to 
Christiania Fjord, and that the Vana longiremis of Meinert from the- 
Kattegat belongs also to this species, 
Echinopleura aculeata, G. O. Sars. (Pl. XVIIL, fig. 40.) 
This Isopod was obtained in the same gathering with the last, and is 
also an addition to the British Crustacean fauna. Two specimens were 
observed, and both were damaged ; it is the best specimen of the two which 
is represented by figure 40 on Plate XVIII. The Norwegian distribution of 
Echinopleura appears to be similar to that of Macrostylis, but Prof. 
Sars remarks that ‘‘it seems everywhere to be very rare.” The form of the 
body and the strongly-serrated margins of the segments impart to 
Echinopleura quite a distinctive character. 
BopyRID&. 
| Phryxus abdominalis (Kroyer). 
This Epicarid was moderately frequent on the specimens of Spironto- 
carts securifrons captured by the “Garland” off Aberdeen in October and 
November last. What appears to be the same species of Phryxus was
