272 Part III. — Nineteenth Annual Report 



British record for Arcturella that T at present know of is that of the late 

 Dr. Bobertson of Millport for the Clyde ; he dredged it off Blackwater- 

 foot, Arran, Firth of Clyde, in 20 fathoms.* 



Mtjnnid^;. 



Paramunna 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 inerme, G. 0. Sars. 



P. inerme was dredged off Aberdeen by the " Garland " in 45 fathoms 

 on November 7th, 1900. 



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. 



Desmosomid^e. 



Macrostylis spinifera, G. O. Sars. (PI. XVIII., 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 mentions 

 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. (PI. XVIII. , 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. 



Bopykid^:. 



Phryxus abdominalis (Kroyer). 



This Epicarid was moderately frequent on the specimens of Spironto- 

 caris securifrons captured by the "Garland" off Aberdeen in October and 

 November last. What appears to be the same species of Phryxus was
