Pleustid^:. 



Parampkithoe monocuspis, G. 0. Sars. 



This species and the closely-allied form Parampluthoe 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). ( = Ampkithoe 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. 



Epimerid,e. 



Epimeria cornigera (Fabricius). 



This fine species was moderately frequent in some material collected by 

 the "Garland" off Aberdeen in 32J 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. 



Eusirim;. 



Eusirus 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 32J fathoms on October the 

 12th, and again on October 23rd in 36 to 49 fathoms; in this last 

 gatheriug the species was moderately frequent. 



Calliopiid^. 



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 — Apherusa furinii (M.-Edw.) — was obtained in a gathering 

 of Cru&tacea collected in Bay of Mgg with a hand tow-net and rowing-

Atylidje. 



Paratylus ancinatus, 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.
