PLEUSTIDZE. 
Paramphithoé monocuspis, G. O. Sars. 
This species and the closely-allied form Paramphithoé bicuspis were 
obtained in gatherings collected off Fair Island in October, and in one 
collected off Aberdeen in 45 fathoms, November 7th, 1900. In the 
gathering collected off Aberdeen P. monocuspis was much more frequent 
than the other. 
Sympleustes latipes (M. Sars). (= Amphithoé latipes, M. Sars.) 
A few specimens of this species were obtained in a bottom gathering of 
Crustacea collected by the “Garland” off Aberdeen in 60 fathoms, | 
October 25th, 1900. 
EPIMERIDA. 
Epimeria cornigera (Fabricius). 
This fine species was moderately frequent in some material collected by 
the “Garland ” off Aberdeen in 324 fathoms, October 12th, 1900; one or 
two of the specimens in this gathering were of a nearly white colour. 
Epimeria cornigera was also moderately frequent in some of the 
gatherings collected eastward of Fair Island in the same month. 
KUSIRIDA. 
Husirus longipes, Boeck. 
This was dredged by the “Garland” in the Sound of Mull in 72 
fathoms, on March 31st, 1900; it also occurred in some material col- 
lected by the “ Garland” off Aberdeen in 324 fathoms on October the 
12th, and again on October 23rd in 36 to 49 fathoms; in this last 
gathering the species was moderately frequent. 
CALLIOPIIDA. 
Apherusa borealis (Boeck). 
This was moderately frequent in material collected in Aberdeen Bay on 
June 28th. Another species—Apherusa bispinosa (Bate)—was obtained in 
a gathering collected off Aberdeen in 60 fathoms, on October 25th ; while 
a third species—A pherusa furinic (M.-Edw.)—was obtained in a gathering 
of Crustacea collected in Bay of Nigg with a hand tow-net and rowing- 
boat by Mr. Williamson, July 27th (1900). 
ATYLIDA. 
Paratylus uncinatus, G. O. Sars. 
This is the species which has no projections on the dorsum, but which 
otherwise somewhat resembles Paratylus falcatus (Metzger). P. uncinatus 
occurred in some material collected in Aberdeen Bay on June 28th, and 
also in the same gathering from Bay of Nigg which Mr. Williamson. 
collected on July 27th, 1900. The species was very sparingly represented.
